We would like to introduce our company's "disaster response capabilities." After a disaster, rapid investigation, accurate diagnosis, and appropriate response are essential. When the impact of a disaster is significant, restoring the surrounding environment that protects power plants is also crucial. We respond to the collapse of irrigation channels, erosion, submersion of PCS, and the collapse of structures due to snow, while striving for appropriate on-site restoration and conducting investigations for insurance purposes. 【Disaster Response】 ■ On-site investigation using drones and visual inspection ■ Emergency inspection and diagnosis ■ Equipment replacement ■ Civil engineering restoration work ■ Waste disposal *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce our "Inspection, Diagnosis, and Evaluation" services. Even with remote monitoring and annual inspections, symptoms of decreased power generation and insufficient power generation are increasing. Therefore, it is necessary to investigate and analyze the issues with the power generation equipment. Additionally, to mitigate abnormalities in power supply during disasters, we respond with qualified diagnostics and prompt action. [Inspection Contents (Partial)] ■ Issue Investigation ■ Internal Resistance Inspection of Panels ■ Infrared Drone ■ Internal Damage Inspection of Modules ■ Insulation Resistance Inspection ■ Ground Resistance Inspection ■ Cubicle Inspection *For more details, please refer to the PDF materials or feel free to contact us.

Our company offers maintenance called 'Dr. Repowering' that does not reduce power generation. Solar panels are advertised as maintenance-free, but dirt on the panel surface becomes increasingly difficult to remove over the years, leading to a decrease in power generation. We would like to propose that you reconfirm whether your original power generation capacity is being maintained. If our company cleans the panels, power generation can increase by 180%. [Features] ■ Restores power generation to the state at the time of installation, enhancing asset value ■ Power generation increases by 180% *For more details, please refer to the PDF document or feel free to contact us.

Our company conducts "repowering" to restore the power generation efficiency of solar panels through cleaning. We can propose a construction plan based on the site environment and the attributes of the dirt, so please feel free to consult with us. If you wish to remove any severe dirt and restore the panels to their original power generation capacity, we can suggest panel cleaning machines for thorough manual work, speedy operations within a limited time, and low-cost cleaning. Additionally, we consider environmental aspects and cost reduction by using ultra-fine bubbles that demonstrate high cleaning power through their penetration ability. 【Features】 ■ Measurement of power generation before and after cleaning is possible ■ Evidence of cleaning effectiveness can be provided ■ Replacement and disposal of defective panels are possible *For more details, please refer to the PDF document or feel free to contact us.

At Ozawa Maintenance, we also carry out grass cutting at power plants. For solar power plants, weeds are one of the significant factors that can lead to a decrease in power generation efficiency. Our company conducts thorough preliminary surveys to identify high-priority areas based on the growth of weeds. At the same time, we mark hazardous locations on the plans to ensure that workers remain vigilant. The grass cutting machines we use have a scissor-like structure, which prevents them from pinching cables above a certain thickness and eliminates the risk of stones being thrown. **Features** - Proven track record of 90MW - Conduct preliminary surveys to select high-priority areas based on weed growth - Use grass cutting machines that do not throw stones - Mark hazardous areas on-site and carry out work under sufficient safety management - Workers are either those who have undergone the required safety training or work alongside trained personnel *For more details, please refer to the PDF materials or feel free to contact us.*

At Ozawa Maintenance, we conduct inspections of power plants. We simultaneously measure open circuit voltage and short circuit current to assess the power generation status of the modules. Our services include I-V measurement inspections, ground resistance inspections, and power conditioner performance inspections. We provide a comprehensive service from "assembly" to "maintenance." You can trust us with the inspections of your power plant! [We offer the following inspections] ■ I-V measurement inspection ■ Insulation resistance inspection ■ IR measurement inspection ■ Ground resistance inspection ■ Module inspection ■ Power conditioner performance inspection ■ Internal damage detection inspection of modules *For more details, please refer to the PDF document or feel free to contact us.
