Tokyo-based Girasol Energy and the enterprise bureau of Japan’s Yamanashi prefecture are renewing Japan’s oldest PV system, a 100 kW array inbuilt 1993. The challenge goals to partially substitute the unique 13.3% environment friendly photo voltaic module, which gives a substitute for dismantling and recycling. system elements.
Japanese startup Girasol Energy and the enterprise bureau of Yamanashi prefecture have collectively repowered the nation’s oldest PV system – a 100 kW array deployed in 1993.
The system has a 95 kW inverter and 1,800 photo voltaic modules with an influence conversion effectivity of 13.3%, unfold over a land space of 751 sq. meters.
“We have redesigned the plant to maximise efficiency and keep operations by making focused enhancements primarily based on extremely correct anticipated energy technology calculated utilizing simulation expertise derived from massive information evaluation,” mentioned Sunflower Energy. “Instead of utterly changing the photo voltaic panels, we normally restore the cables, restore the elements of the communication system and substitute the inverter.”
Girasol Energy mentioned that repairing the techniques, relatively than recycling the elements, is a sensible answer for PV techniques that can see their feed-in tariff finish within the coming years.
“WI consider that by shortly figuring out faulty elements and making applicable repairs, even small and medium-sized energy vegetation which were put in for a few years can proceed to be worthwhile,” the corporate mentioned.
The firms didn’t disclose additional technical particulars in regards to the PV system, which at present powers close by eating places and a golf course. The renovation challenge is a part of an initiative launched by the enterprise bureau.
“This is the primary try at first to goal for 50 years of PV system operation,” the corporate mentioned in a press release. “Renovating a solar energy plant doesn’t imply changing all the gear. We have been capable of clearly present a path to the long run the place electrical energy technology might be restored by making appropriate redesign when gear breaks down or reaches the top of its helpful life.
The firms have developed an Internet of Things (IoT) platform that enables real-time, distant monitoring of photo voltaic vegetation, permitting operators to trace information from sensors with out extra line of communication.
