Next Energy Builds Solar Plant Using Reused Solar Panels in Nagano

Next Energy & Resources Co Ltd built a solar power plant by using only reused solar panels and had a ceremony to celebrate the completion of the plant June 3, 2018.

For the plant, “PV Next Komagane Solar Power Plant,” Next Energy (Komagane City, Nagano Prefecture) installed five kinds of reused solar panels (1,202 panels in total) by renting 6,749.1m2 of land that is owned by Komagane City and was formerly used for Inan Cleaning Center (incinerator plant for combustible materials). The total capacity of the solar panels is 280.78kW.

Though the names of the manufacturers of the used solar panels were not disclosed, monocrystalline silicon (Si), polycrystalline Si and CIS-based solar panels were adopted. The plant started commercial operation May 30, 2018.

Next Energy selected products that meet the conditions for the facility certification of Japan’s Ministry of Economy, Trade and Industry (METI). And it sells electricity generated at the plant based on the feed-in tariff (FIT) scheme.

Also, as measures for local disaster prevention, Next Energy installed an off-grid system (solar power generation facilities that independently store electricity) and solar-powered street lamps. Furthermore, with consideration for surrounding environments, the company conducted a voluntary environmental assessment and planted trees around the plant. And it will promote the use of the plant for environmental education by accepting visitors.

In 2005, Next Energy started a business of reusing solar panels that were once installed and operated. Since 2015, it has been engaged in the construction of solar power plants to be owned by the company using the “Reborn Technology,” its own technology for selecting high-quality reused panels. The PV Next Komagane Solar Power Plant is its second power plant built by using reused solar panels.
