Okamura Sangyo Co., Ltd. provides 'O&M support' for solar power plants. With our monitoring system "Plant Manager," we conduct daily web patrols of our customers' power plants to check the operational status of the equipment. Visual checks of the power plants allow us to quickly identify local issues such as weed growth, panel dirt, and cracks that cannot be discerned from graphs. Additionally, we conduct annual inspections: low voltage every two years and high voltage annually, and we provide a work report via email approximately 10 days after the completion of the work. If any issues are discovered during web patrols or alert emails, we will respond on-site within 72 hours on business days to identify the cause of the failure and carry out repairs. We protect solar power plants with consistent support from web patrols to annual inspections and on-site responses in case of failures!

• Harbor Construction

In 1973, Okamura Industries began with electrical wiring for homes. What I always thought about on-site were small innovations and preparations. In our efforts to improve the site, we have gradually made small proposals and taken steps forward. In recent years, we have started basic design and construction of solar power plants. In Japan, which lacks resources, renewable energy enriches everyone's daily life and living. Based on the experience we have cultivated on-site, we aim to become pioneers leading into the future, contributing to the creation of a circle of energy that can be shared and used by everyone around the world, pursuing and delivering further "creation" to you. 【Business Activities】 ○ Sales of the renewable energy remote control panel "Power Plant Manager" ○ Sales and construction of solar power generation systems ○ Design and construction of electrical equipment work For more details, please contact us or download the catalog.
