The "Power Plant Manager Web Patrol Service" is a solar power plant O&M service where specialized staff patrol your power plant online every weekday to check the operational status of the equipment. We confirm the power generation status and any faults of the PCS (power conditioner) alone. If power generation is low, we assess the situation based on local weather conditions. In addition to conducting "annual inspections" targeting access roads, parking lots, fences, and solar panels, we also create monthly reports and provide "on-site response" for initial actions when the power plant experiences abnormalities. 【Service Contents (Partial)】 ■ Daily WEB Patrol (Monitoring) ■ Annual Inspections (Low Voltage: once every 2 years, once a year) ■ Creation of Monthly Reports (Downloadable from the WEB) ■ On-site Response (from receiving alert emails to initial actions) ■ Support for Regular Reports to the Ministry of Economy, Trade and Industry (JPEA) *For more details, please refer to the PDF document or feel free to contact us.

The Energy Management System (EMS) "Power Plant Manager" is an EMS that can centrally manage a wide range of devices, including not only the measurement of electricity usage but also self-consumption solar power, storage batteries, and EV chargers. It uses a mobile line that does not require a local communication line, allowing for secure connections. Measurement data is stored on a cloud server, enabling data management anytime and anywhere, and since there is no data on-site, there is no risk of data loss in the event of terminal failure. 【Features】 ■ Can centrally manage a wide range of devices ■ Uses a mobile line for secure connections ■ Measurement data is stored on a cloud server ■ No risk of data loss in the event of terminal failure *For more details, please refer to the PDF document or feel free to contact us.

Okamura Sangyo Co., Ltd. provides "O&M support" for solar power plants. Our monitoring system, "Plant Manager," conducts daily web inspections of your power plant to check the operational status of the equipment. Visual checks of the power plant allow for quick identification of on-site 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, with a work report sent via email approximately 10 days after the completion of the work. If any issues are discovered during web inspections or alert emails, we will respond on-site within 72 hours on business days to identify the cause of the failure and restore functionality. We protect solar power plants with consistent support from web inspections to annual checks and on-site responses during failures! 【Service Contents】 ■ Daily web inspections ■ Annual inspections ■ On-site response ■ Other support *For more details, please refer to the PDF document or feel free to contact us.

In 1973, Okamura Sangyo began with electrical wiring for homes. What I always thought about on-site were small innovations and preparations. We have gradually made progress by accumulating small proposals to improve the site. In recent years, we have started the 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 remote control panels for renewable energy "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.
