List of maintenance plans（２）
Spot inspection
Solar power generation is a “high-performance system.” Systems have a limited lifespan and failures are inevitable.
If your solar power generation device has not been inspected by a professional since purchase, there is a high possibility that it may have defects, so we recommend that you get a second opinion.

※This service is for low voltage 50KW or less, so if you have high voltage equipment, please contact us at 03-6264-6808.
※This service is available nationwide, but may not be available to some remote islands.
※For roof installation, an elevated workbench may be required separately.
Emergency rush
In the event of a problem such as a sudden drop in power generation, our experts will rush to the site on behalf of the business owner and investigate the cause with on-site response to avoid further problems.

Weed control/panel cleaning
Leaving weeds unattended will not only reduce power generation, but may also lead to system failure.
Stubborn panel stains can become hot spots and cause system failure or fire, so regular maintenance is required.
Weeds grow quickly in sunny solar power plants, so regular countermeasures are necessary.
Although it is often not anticipated at the beginning, the huge amount of weeds that grow in summer is one of the serious problems that can reduce power generation efficiency. Not only do weeds block sunlight, but weeds also become a source of damage from birds, animals, and insects, which increases the amount of dirt on the panels, leading to a significant drop in power generation efficiency. Weed control methods vary depending on the type of weed, the height of the mount, and the cable piping method, so we will make the best proposal for the owner’s solar power plant.
Cleans stubborn dirt that won’t come off in the rain.
Stains such as feces, dirt, dust, sand, exhaust gas, volcanic ash, and pollen gradually harden and become stubborn stains. These dirt impedes the transmission of visible light necessary for power generation, so if dirt accumulates on the panel surface over many years, power generation efficiency will definitely decrease. Dirt that cannot be removed by rain, such as feces damage, can cause hot spots and fires, so we recommend regular panel cleaning.
