小澤メンテナンス List of Products and Services

We would like to introduce our company's "disaster response capabilities." After a disaster, rapid investigation, accurate diagnosis, and appropriate response = response capability are essential. When the impact of a disaster is significant, restoring the surrounding environment that protects the power plant 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.

• Environmental Survey

We would like to introduce our "Inspection, Diagnosis, and Evaluation" services. Even with remote monitoring and annual inspections, there has been an increase in symptoms of reduced power generation and insufficient electricity production. Therefore, it is necessary to investigate and analyze any issues with the power generation equipment. Additionally, to mitigate power supply abnormalities during disasters, we provide qualified diagnostics and prompt responses. 【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 document 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 the dirt on the panel surfaces becomes increasingly difficult to remove over the years, leading to a decrease in power generation. We would like to offer you the opportunity to reconfirm whether your panels are maintaining their original power generation levels. 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 characteristics 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, or low-cost cleaning options. Additionally, we consider environmental aspects and cost reduction by using ultra-fine bubbles, which demonstrate high cleaning power through their penetrating 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 perform 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 areas of high importance based on the growth of weeds. At the same time, we mark dangerous areas on the drawings to ensure that workers are fully aware of the hazards. 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】 ■ Achievements of 90MW ■ Preliminary surveys conducted to identify high-importance areas based on weed growth ■ Adoption of grass cutting machines that do not throw stones ■ Marking of dangerous areas on-site, ensuring adequate safety management during operations ■ Workers are either those who have undergone the required safety training or work alongside trained personnel *For more details, please refer to the PDF document or feel free to contact us.
