6 Measures to Prevent Power Loss from Grass Cutting Management at Solar Power Plants

Maintenance of a solar power plant involves not only inspections of panels and power conditioners but also on-site vegetation control such as mowing, which is an important task to protect power generation. When weeds grow, they can cast shadows on the lower edges of panels and around mounting structures, causing generation losses. Furthermore, it can worsen inspection access, lead to missed checks around cables, cause poor drainage, allow intrusion by birds, wildlife, or small animals, and increase the risk of accidents during work, all of which may affect the overall operation and maintenance of the plant.

Grass cutting is not sufficient if done simply by "cutting when it grows." It is important to manage it proactively and systematically, taking into account site conditions, season, panel layout, racking height, surrounding environment, and inspection frequency. This article explains, for operational staff of solar power plants, the approach to grass-cutting management to reduce generation losses and six practical measures that are easy to implement on site.

Why Vegetation Management at Solar Power Plants Reduces Power Generation Loss

In solar power plants, sufficient sunlight reaching the panels is necessary to ensure power generation. Therefore, when weeds grow up to the front or bottom edge of the panels, they can cast shadows on some panels or cells and cause a reduction in power output. This is especially true at plants with low mounting structures or where the clearance from the ground to the bottom edge of the panels is limited, making them more susceptible to the height of the vegetation.

Shadows from weeds are easier to overlook than those from trees or buildings. If they only cast shadows in the morning or evening, the problem may not be visible depending on the inspection time. Also, when grass height suddenly increases from the rainy season into summer, places that were fine at the previous inspection can quickly become conditions that affect power generation. When considering grass-cutting management as a measure against power loss, it is important to estimate not only the current grass height but also how much it will grow before the next inspection or the next mowing.

Power generation losses are not necessarily noticeable at the plant level. If only a particular string, row, or section is affected by weeds, the loss can be buried within the total output and detection may be delayed. In practice, rather than waiting to confirm a drop in generation before mowing, it is important to proactively manage locations that are prone to shading.

Grass cutting management also affects inspection quality. If the grass grows too long, workers have difficulty accessing under the racks and around junction boxes, making it hard to check for cable damage, abnormalities around terminal boxes, and clogged drains. When you cannot see your footing, the risk of trips, falls, and stepping through weak spots increases. Grass cutting is not only for maintaining appearance; it is a basic task for safely inspecting power generation equipment and detecting abnormalities early.

Furthermore, when weeds die and dry out, they can contribute to an increased risk of fire spread. The accumulation of dead grass near cables and electrical equipment is undesirable in power plant management. If clippings are left after mowing, they can be blown around equipment by the wind or obstruct drainage. Mowing management needs to cover not only the cutting work but also inspection of the post-cut condition.

Thus, vegetation management is maintenance that supports power generation, inspection access, safety, and disaster resilience. To minimize generation losses, it is important not to treat weeds merely as an aesthetic issue, but to regard them as a factor affecting the power plant's performance and management quality.

Measure 1: Prioritize managing areas where grass casts shade

The first thing to consider in mowing management is which areas to prioritize for maintenance. It may seem ideal to mow the entire power plant uniformly short, but the site is constrained by factors such as area, working time, budget, weather, and number of workers. Therefore, it is important to prioritize areas that are more likely to cause generation losses and manage them efficiently.

Pay particular attention to the lower edges of the rows closest to the front of the panels. Where the clearance from the ground to the panels is low, even a slight increase in grass height can easily cast shadows. At south-facing or sloped solar plants, the way shadows fall changes with the sun’s elevation and the seasons. During inspections, it is important not only to stand in front of the panels and check how high the grass has grown, but also to consciously verify whether shading is likely at the low sun angles of morning and evening.

Next, attention is also needed at the ends of the racking rows and near boundaries. Areas along fences, at the base of slopes, alongside drainage channels, and near neighboring property lines tend to retain vegetation. Locations that are difficult for large mowers to access or that require manual work are more likely to have uncut vegetation after each maintenance operation. If such areas are close to the panels, they can cause localized shading.

Also, at power plants with elevation differences across the site, attention must be paid to grass that grows from lower areas up to higher ones and to grass that falls or leans down from slopes. Grass heights that are not problematic on flat ground can more easily come close to the panel surface on slopes or where there are level differences. At reclaimed sites or power plants in mountainous areas, the effect of grass varies with the terrain, so it is essential to verify the actual height relationships on site, not just the distances shown on drawings.

To understand the impact of grass, it is effective to inspect the power plant by dividing it into sections. Divide the site into units that are easy to manage on site—per panel row, per junction box, per power conditioner unit, along service roads, on slopes, and along fences—and check grass height and the likelihood of shading. If you make sure to inspect from the same viewpoints each time, changes from the previous inspection will be easier to recognize.

When setting priorities, we look not only at whether shadows that lead to power generation losses are present, but also at whether they interfere with inspections. For example, if grass is dense in front of junction boxes or combiner boxes, it can impede tasks such as opening doors and performing visual checks. Areas where it is difficult to check cable routes or supporting structures should also be mowed early. Even if it does not appear to directly affect power generation, if it causes delays in detecting abnormalities it will ultimately lead to losses at the power plant.

Once you have decided on priority management areas for mowing, it is important to put them in a form that can be shared on site. If you convey information only verbally, management standards are likely to shift when the person in charge changes. Using simple zoning maps, photos, and inspection records to make clear notes such as "this area grows quickly," "this area is prone to shade," and "this area requires manual work" will help stabilize mowing quality.

The purpose of grass-cutting management is not simply to keep the site looking neat. It is to prevent shading that leads to power generation losses and to maintain conditions that make inspections easy. For that reason, the first measure is to identify the locations at each site where the impact is greatest and to prioritize their management.

Measure 2: Plan mowing schedules to match seasonal growth patterns

A common mistake in mowing management at solar power plants is treating mowing the same way year‑round. Weed growth varies greatly with the seasons. From spring into summer growth is rapid and can surge after periods of rain. Conversely, from autumn into winter growth steadies, but the accumulation of dead grass and drying conditions require careful management.

Early spring is the period when grasses that were inconspicuous during winter begin to grow. If management is delayed at this time, grass height can rise rapidly around the rainy season, increasing the workload. Even before large shadows form, identifying locations within the power plant that tend to grow more makes it easier to plan subsequent mowing. During spring inspections, it is effective to check not only grass height but also areas that were overgrown or left uncut in the previous year.

The rainy season through summer is a period when the importance of mowing management becomes particularly high. Rain and higher temperatures cause grass to grow rapidly, so even if only a short time has passed since the last work, vegetation can approach the lower edge of the panels. Because this is also a period when power generation is expected, you want to avoid generation losses caused by shadows from weeds. During this period, in addition to the mowing schedule for the entire power plant, it is advisable to consider supplementary management that prioritizes treating only the areas prone to shading.

During summer operations, attention to worker safety is also necessary. Mowing in high temperatures can quickly deplete physical strength, leading to heatstroke or reduced attention while operating machinery. Forcing the completion of a large area in a single day increases the risk of missed spots and equipment damage. It is important to decide in advance the working hours, breaks, work area, and emergency contact methods, and to balance measures to prevent power generation loss with safety management.

Autumn is a time when grass growth begins to settle down, but it is also a season when dealing with the grass that grew over the summer is often left unfinished. If cut grass or dead grass remains under panels, in drainage channels, or along fences, it can cause poor drainage or become a habitat for small animals. In autumn mowing, it is important not only to reduce grass height but also to check the accumulation of clippings and the drainage routes. After typhoons or heavy rains, you should also check whether fallen grass or inflow debris is obstructing drainage.

Because grass grows less in winter, mowing is often required less frequently, but it is best to avoid stopping maintenance entirely. Check whether dead grass has accumulated around equipment, become entangled in fences or mounting racks by strong winds, or is obstructing inspection routes. At power plants with a lot of dry dead grass, tidying up around equipment is also necessary from a fire-prevention standpoint.

When making an annual plan, it is important not to think only in terms of how many times to mow per year. The required maintenance frequency varies depending on the power plant’s location, grass species, soil type, sunlight exposure, rainfall, seeds blowing in from surrounding areas, and whether slopes are present. By reviewing last year’s records to see which sections became problematic at which times and reflecting that in the next year’s plan, you can reduce unnecessary work while more easily preventing generation losses.

A mowing plan is effective not only for setting the work date but also when coordinated with inspection dates and power output checks. Take site photos before mowing and check the same locations after the work; by then observing subsequent power generation and trends for each string, it becomes easier to determine how much mowing contributes to reducing generation loss. Planning that takes seasonal growth patterns into account is the foundation for keeping power plant maintenance stable.

Countermeasure 3: Establish work rules for under the panels and around the mounting racks

Grass cutting at solar power plants is particularly difficult under the panels and around the mounting structures. While wide aisles and flat areas are relatively easy to work in, the lower edges of panels, the legs of the mounting structures, areas around cables, and around junction boxes are close to equipment and require careful work. If the work rules for these areas are unclear, the risk of leaving uncut vegetation or damaging equipment increases.

The area beneath the panels is prone to causing shading if grass is left behind. In particular, on the front-row side or with low-mounted racking, even a slight growth of grass near the panel edges can have an effect. That said, forcing machinery in can risk contact with the panel undersides, cables, the racking, or piping. Before starting work, it is important to decide how far to mow with machinery and where to switch to manual work.

The area around the mounting frame legs is prone to grass entanglement and often has uncut patches. When grass is dense around the legs, visual inspection of bolts and fastenings becomes difficult. Ground settlement, scour or erosion, and abnormalities around the foundations are also easy to overlook. To ensure grass-cutting management contributes to inspection quality, it is important to keep the area around the mounting frame legs clear and visible.

In front of junction boxes and combiner boxes, the area must be kept clear so workers can stand safely, open and close the doors, and inspect the interior. Dense grass makes footing unstable and worsens workers’ posture during inspections. It can also provide hiding places for insects and small animals. The work space in front of equipment should not just be passable; there must be an awareness to ensure sufficient room and visibility for inspection and restoration work.

As part of the work rules, setting a guideline for cutting height makes management easier. Cutting too short can damage the ground or increase the risk of flying stones. Conversely, leaving it too high will quickly cause shading again. Depending on site conditions, it is important to determine a height that minimizes impact on equipment while making it easier to ensure work safety, and to share that among the persons responsible.

Also, the direction of work is important. Swinging a brush cutter toward panels or cables increases the risk of flying stones and contact with the blade. In locations close to equipment, you need to decide the cutting direction, the operator’s position, and procedures for checking the surroundings. When working with multiple people, keep sufficient distance from each other and ensure work areas do not overlap.

Before starting work, it is advisable to set aside time to confirm the locations of equipment. Especially when workers are entering the site for the first time or when external contractors are performing work, drawings alone cannot fully convey the on-site points to watch for. Places where cables run close to the ground surface, where piping is exposed, where inspection ports are present, and where there are level differences in the ground should be shared in advance. Because it is too late if these are noticed after work has begun, an on-site check before starting work is important.

After mowing, check for grass left uncut under the panels and around the mounting racks. Even if it looks cut from the worker’s eye level, from a distance there may be grass that could reach the panel surfaces. When checking, look from multiple angles — in front of the panel rows, from oblique directions, and from the aisle side — to reduce the likelihood of overlooking anything.

Mowing beneath panels and around the racking is a task that must consider both preventing generation loss and protecting equipment. By making work rules clear and sharing site-specific precautions, you can simultaneously reduce the risk of areas being left uncut and of equipment damage.

Measure 4: Adopt a safe mowing method that does not damage cables or pipes

Although vegetation management is intended to prevent power generation losses, if cables or conduits are damaged during work it can lead to power outages and restoration work. At solar power plants, cables often run under panels and along the racking, and in some locations they may be close to the ground or hidden by grass. During mowing operations, preventing damage to equipment must be the top priority.

Particular attention should be paid to brush cutter blades and flying stones. If metal or hard blades are used, they can fling stones from the ground and strike panels, cables, or piping. Damage to the front or back of a panel may be hard to detect by visual inspection but can lead to long-term degradation or reduced power generation. When working near equipment, it is important to carefully consider the tools used, the direction of cutting, and the working distance.

On sites where cables are hidden in grass, it is dangerous to start cutting with a machine right away. First visually confirm the cable route and, if necessary, remove the surrounding grass by hand. If the cable is sagging or a fastener has come off, record the situation and share it with the supervisor before grass-cutting work. Pulling grass out forcefully can put strain on the cable or its fixtures, so handle any entwined grass carefully.

The same applies around pipes and protective conduits. Pipes buried in grass or soil and hard to locate are more likely to be struck by a brush cutter. Be especially careful around sections that are slightly exposed above the ground, bends, and risers. If there are areas that were repaired in the past or are temporarily protected, sharing that information before work begins will help prevent accidents.

Along fences and around gates, communication lines, grounding wires, and wiring for security equipment may be involved. Even if the area being mowed is not directly beneath power generation equipment, damaging surrounding equipment can cause management issues. In power plant maintenance, it is necessary to adopt a perspective that protects not only equipment directly related to power generation but also facilities related to monitoring, communications, security, drainage, and grounding.

To ensure safe mowing, perform a pre-work hazard check and a post-work abnormality check as a set. Before work, check for locations where cables are exposed, where piping is close to the ground surface, where there are many stones, and where slopes make footing unstable. After work, check for damage to cable jackets, damage to piping, loosened fasteners, stone-chip marks on panels, and accumulation of cut grass around equipment. If any abnormalities are found, record them in accordance with the power plant’s management rules and take the necessary actions.

When hiring external workers to mow, it is important not to leave the job entirely to them as if it were ordinary weeding. At solar power plants, because power-generation equipment is located immediately adjacent to the areas to be mowed, the precautions differ from mowing in ordinary vacant lots or along roadsides. Before work begins, you should share the equipment layout, no-entry zones, locations that require manual work, and the contact information to use if any abnormalities are found during the work.

Also, during grass-cutting work, you should not touch power generation equipment, lift cables, or alter how the equipment is secured without authorization. Even if grass is entangled and makes the work difficult, pulling it forcibly can cause other malfunctions. It is advisable to have a system in place to confirm any equipment-related decisions with the power plant manager or a person knowledgeable about electrical equipment.

Mowing management is work that both prevents power generation loss and avoids damaging equipment. By codifying safe cutting methods and sharing them with workers, you can reap the benefits of weed control while minimizing unnecessary shutdowns and repair risks.

Countermeasure 5: Check records and changes in power generation after mowing

To use mowing management effectively as a countermeasure against power generation losses, it is important not to stop at simply completing the work. Record when, where, and to what extent you mowed, and compare those records with subsequent power generation and site conditions to improve management accuracy for future rounds. If work continues without records, you may repeat the same problems in the same places each year or do more work than necessary.

First, what you should keep are photos taken before and after mowing. Photos are useful for checking grass height, the presence or absence of shadows, missed cuts, and the condition around equipment. Keeping the shooting position consistent each time makes it easier to compare with previous photos. Decide on fixed points at locations that tend to be problem areas on site—such as the ends of panel rows, slopes, along fences, around junction boxes, drainage ditches, and access roads—to improve continuity of management.

You need to record the work area as well as taking photos. Note whether you mowed the entire power plant or only certain sections, where manual work was performed, and where areas were left uncut. Also record spots where the grass was very dense during the work or where machinery had difficulty accessing, as this will help with the next plan. Especially when the plant is large or you manage multiple sites, management that does not rely on memory is indispensable.

When checking power generation, looking only at total output before and after mowing may be insufficient. Because weather and irradiance change, simply comparing daily outputs before and after the work makes it difficult to judge the effect of mowing alone. If possible, examine differences between sections within the same plant, differences between strings, trends at the inverter unit level, and comparisons of days with similar irradiance conditions to confirm whether locations suspected of being affected by grass have improved.

For example, if only specific rows or sections have lower power generation and grass shadows were observed on site, mowing and then checking whether the difference narrows makes it easier to judge whether weeds were a loss factor. However, differences in generation can also be related to panel soiling, equipment malfunction, wiring faults, solar irradiance conditions, temperature, snowfall, or other causes of shading. If mowing does not produce improvement, it is important to suspect factors other than weeds and broaden the scope of inspection.

Records also help confirm work quality. By looking at photos taken after mowing, you can see whether areas under panels or around equipment were left uncut. If the same locations are left uncut each time, there is room to improve the work methods, tools, or instructions about the work scope. If the work is outsourced, using the records to align the work details with the contractor makes it easier to stabilize quality going forward.

Also, grass-cutting records are important as part of a power plant’s management history. When multiple stakeholders such as the owner, operations personnel, maintenance staff, and contractors are involved, being able to share the status of grass cutting makes it easier to handle inquiries and explain issues during incidents. If there are recent grass-cutting records and site photos when a drop in power generation occurs, the initial steps to isolate the cause can be taken more quickly.

To continue keeping records, it’s important not to make operations too complicated. If there are too many items that are difficult to enter on site, you won’t be able to keep it up. By narrowing management to the items needed for field work—work date, work area, an overview of grass height, presence or absence of shadows, any uncut areas, presence or absence of equipment damage, photos, and notes for the next visit—you can keep useful records while reducing the burden.

By making it routine to record mowing activities and check power output afterward, mowing changes from a mere periodic task into an improvement activity aimed at reducing generation losses. Visualizing site conditions and linking them with generation data to inform decisions leads to more effective maintenance.

Measure 6 Manage the entire site, including drainage, wildlife control, and fire prevention

Grass cutting management at solar power plants not only prevents shading of the panels but also helps maintain the overall condition of the site. If weeds grow too tall, various problems are likely to occur in areas such as drainage, bird and wildlife measures, fire prevention, inspection access routes, and fence management. To prevent generation losses, it is necessary to consider not only direct shading but also a perspective that reduces operation and maintenance risks across the entire plant.

On drainage surfaces, grass and cuttings can block drains, catch basins, side ditches, and culvert inlets. When drainage deteriorates, water can accumulate on the site, causing muddiness, erosion, ground destabilization, and deterioration of maintenance roads. Changes in water flow around mounting foundations can also affect long‑term stability. When mowing, it is important to ensure that drainage routes are visible and that cut grass is not obstructing the flow.

On slopes and developed land, cutting all the grass very short is not always the best approach. Suddenly removing grass that had been protecting the ground surface can affect rainwater flow and soil erosion. On the other hand, if grass and trees are left to grow too large, they can cause root-related impacts, tree falls, poor drainage, and make inspections difficult. On slopes, management must be carried out while balancing shading of power-generation equipment, sediment runoff, and worker safety.

Grass cutting is important for measures against wildlife and small animals as well. Areas where grass is tall and dense make it easy for small animals, birds, and insects to hide. If animals enter the power plant, it can lead to cable damage, nesting, droppings, and hazards during inspections. Under fences and near gates, around cable racks, and near junction boxes are places where visibility should especially be ensured. Managing grass also helps with early detection of abnormalities.

From a fire-prevention perspective, it is important to avoid the accumulation of dead grass. If dry grass accumulates around power generation equipment, it can become a factor in the spread of fire. Check around electrical equipment, around power conditioners, around junction boxes, at cable risers, and along fences for any accumulated cut grass or dead grass. Because cut grass left lying after mowing can be blown by the wind toward equipment, a post-work inspection is necessary.

Site boundary management must not be overlooked. When grass grows along the fence, it can hide fence damage, holes, or potential entry routes. If grass encroaches onto neighboring land, it can lead to disputes with nearby residents. Because power plants are often operated unmanned, how the site appears from the surroundings and boundary management are also part of maintenance quality. During mowing, it's a good idea to check not only the power generation equipment side but also the outside of the fence and its relationship with adjacent properties.

To manage the entire site, it is important not to separate grass-cutting operations from on-site inspections. Days when you enter the site for grass cutting are an opportunity to simultaneously check panel shading, around the racking, drainage, fences, cables, maintenance roads, slopes, signage, gates, and so on. Even if the grass-cutting crew and the inspection personnel are different, when you find an anomaly, take a photo and establish a process to share it with the manager so site information can be used effectively.

If vegetation management is regarded as part of overall site maintenance, it not only prevents generation loss but also extends benefits to failure prevention, work safety, neighbor relations, and disaster prevention. To ensure the long-term stable operation of a power plant, it is important not to treat weeds as a standalone problem but as part of the site's overall risk management.

On-site operational tips to make mowing management easier to sustain

Vegetation management is not a task that ends once it's been cleaned up. A solar power plant is a facility that is operated over the long term, and weeds grow back every year. Therefore, making operations easy to sustain is important for preventing power generation losses. No matter how carefully a plan is made, a system that is difficult to implement on site will not be sustained.

First, it is important to make management standards that can be judged on-site. The phrase "cut the grass when it grows" alone will lead to different judgments depending on the person. If you define criteria that can be seen on-site—such as whether vegetation is approaching the lower edge of the panel, blocking inspection walkways, making work difficult in front of junction boxes, or obstructing drainage paths—decisions become more consistent. Ideally, this will allow the same quality of management to be maintained even when personnel change.

Next, it is useful to record the characteristics of each power plant in the management documentation. Even within the same solar power plant, grass growth varies by plot. Sunny spots, damp areas, slopes, along fences, places where seeds easily enter from neighboring land, areas that are difficult for vehicles to access—each has its own characteristics. If you record site-specific cautions, preparation for the next operation will be quicker and missed cutting will be reduced.

Pre-work briefings are also important. Sharing the scope of work, priority areas, precautions for locations near equipment, areas that require manual work, photo locations, and post-work inspection procedures before starting makes it easier to prevent mistakes. When external contractors are involved, it is essential to convey the precautions specific to solar power plants. Even if someone has general grass-cutting experience, different considerations are necessary when working near power generation equipment.

Coordinating grass cutting and inspection work is also effective. After grass cutting, cables, support structure foundations, drainage channels, and the undersides of fences that are usually hard to see become easier to check. Carrying out a simple inspection at this time makes it easier to detect abnormalities early. Rather than scheduling separate days for grass cutting and for inspections, combining them according to site conditions improves travel and work efficiency.

On the other hand, it is also important not to try to forcibly fix any abnormalities noticed while mowing. Electrical equipment, cables, piping, and mounting supports may require specialist assessment. Workers must consistently record photos and location information and report them to the manager. If workers operate equipment, remove cable ties, or pull wiring based on on-site judgments, they may cause additional malfunctions.

When deciding how frequently to mow, consider the balance between its impact on power generation and the workload. Keeping the grass short all the time may seem safe, but the more often you mow, the greater the cost and the more opportunities there are for contact with equipment and work accidents. Conversely, cutting too infrequently lets the grass grow taller, leading to generation losses and making inspections difficult. Using last year’s records, seasonal growth rates, the plant’s terrain, and how easy the work is to perform, find a frequency that suits the site.

When managing multiple power plants remotely, it is efficient to use site photos and inspection records to set priorities before visiting. By checking first the sections showing anomalies in power generation data, the places where grass had grown last time, and the areas prone to vigorous growth before and after the rainy season, you can cover the important spots even with limited time. Linking mowing management with data and site photos leads to more consistent maintenance quality.

For mowing management that’s easy to sustain, a consistently functioning system is more important than a single perfect operation. By integrating management standards, records, work rules, reporting methods, and power generation monitoring into a unified operation, you can create a system that makes it easier to prevent generation losses even when personnel change.

Summary

Vegetation management at solar power plants is an important maintenance activity to prevent generation losses. When weeds cast shadows on panels, power output can decrease, and particular attention is required where mounting structures are low, on slopes or embankments, alongside fences, and near the lower edges of panels. Grass cutting should be regarded not merely as landscape upkeep but as work that protects power output, ease of inspection, safety, and fire prevention.

To carry out effective grass-cutting management, first prioritize areas where shading is likely to occur. Rather than viewing the entire power plant uniformly, it is necessary to identify locations that are likely to affect power generation and inspections, such as in front of panels, the bases of racking legs, around junction boxes, slopes, drainage routes, and along fences. Next, make a plan according to the seasonal growth of grass. Growth is rapid from spring to summer, while in autumn and winter it is important to check for dead grass, drainage, and fire prevention.

Also, under panels and around mounting racks, it is essential to clarify work rules. By deciding in advance how far to cut with machinery, where to switch to manual work, the cutting height, and the work direction, it becomes easier to prevent missed areas and equipment damage. To avoid damaging cables and piping, it is important to check hazardous spots before work, inspect for abnormalities after work, and share precautions with external workers.

After mowing, recording photos and the work area and comparing them with changes in power generation can improve management accuracy. On-site records are useful for distinguishing whether a drop in generation is caused by shading from grass or by other equipment factors. Furthermore, checking the entire site—including drainage, measures against birds and animals, fire prevention, fences, and access roads—contributes to the long-term stable operation of the power plant.

Vegetation management is also a valuable opportunity to check the condition of the power plant each time you enter the site. By combining work plans, on-site photos, inspection records, and power generation data, you can prevent generation losses caused by weeds while enabling early detection of equipment abnormalities. By establishing a continuous maintenance system, it becomes easier to protect the profitability and safety of the solar power plant.

If you want to make mowing management at solar power plants more efficient and visualize on-site checks and measures against generation losses, utilizing systems that support inspection records and site management can also be effective. It is important not to leave daily maintenance as person-dependent work, but to organize photos, location information, inspection histories, and site-specific notes, and to establish an operational system that can be continuously improved.
