Solar power generation, which was once said to be maintenance-free, is now required to have "maintenance and management" mandated by the revised FIT law enacted in April 2017. It has become necessary to conduct regular inspections at least once every four years. Without maintenance, issues can arise such as unnoticed power converter failures leading to sales losses (equipment failure) and the accumulation of dirt on panels causing deterioration (efficiency decline). Japan Inspection, part of the San-Ei Group, conducts maintenance for solar power plants as its main business. We also offer O&M services that can manage everything from regular inspections to weed control monitoring. 【Examples of Maintenance and Daily Inspection Contents】 ■ Is the power generation unusually low despite good weather? ■ Are there any errors occurring? ■ If surveillance cameras are installed, regularly check the site. ■ Is there an overgrowth of weeds? ■ Check for any foreign objects, etc. *For more details, please refer to the related links or feel free to contact us.

We held a demonstration tour of our popular panel cleaning service, which is part of the maintenance services we offer, and we would like to introduce it to you. If the force applied is incorrect, the panels can crack. If the degree of dirt on the panels is not properly assessed, the dirt may not be completely removed, leading to the need for re-cleaning, and overlooking dirt can result in hot spots. Dirt on the panels accumulates daily, and as time passes, it can more easily affect power generation. We hope that this opportunity will help more people understand the importance of panel cleaning. If you are interested, please first refer to our recovery profit simulation. *For more details, you can view them through the related links. For further inquiries, please feel free to contact us.

We would like to introduce seasonal solar power generation troubles. There are two main types of solar power generation troubles caused by snowfall: one is that snow accumulates and blocks sunlight, leading to a decrease in power generation, and the other is that if too much snow accumulates, the panels or mounting structures may not be able to withstand the weight and could be damaged. The first measure against snow is proper installation, and if there are consecutive snowy days or a possibility of heavy snowfall, it is best to clear the snow. Our company not only provides installation services for solar power plants but also offers consistent maintenance services afterward, and we also provide O&M services that encompass maintenance and management. 【Examples of solar power generation troubles】 ■ Decrease in power generation ■ Accumulated snow may slide off and affect the lower parts ■ Panels may crack under excessive weight ■ Mounting structures may collapse under the weight ■ There is a possibility of secondary disasters affecting adjacent land *For more details, please refer to the related links or feel free to contact us.

In recent years, the decline in electricity sales prices has led to a decrease in the construction of large-scale power plants. Conversely, the introduction of solar power generation facilities is gaining increasing attention as a countermeasure to the rising electricity rates. Solar power generation equipment has fewer installation restrictions, allowing it to be installed almost anywhere that receives sunlight, such as roofs, walls, and even slopes that are usually difficult to utilize. This makes it possible to introduce solar power systems in factories and other locations. We propose suitable solar power generation facilities and installation methods tailored to our customers' needs and carry out the construction. *For more details, please refer to the PDF document or feel free to contact us.*
