Japan Photovoltaic Energy Association panel shipments in 2015. Japan Photovoltaic Energy Association Japan Photovoltaic Energy Association (JPEA) is the best-known body for solar photovoltaic energy companies in Japan. Founded on April 23, 1987, it has a number of objectives and activities, one of which is providing the JPEC certification for solar modules in the Japanese market. The association serves as a spokesperson for the photovoltaics energy industry in Japan. JPEA set a pathway for the photovoltaic industry in Japan to reach 100 GW by 2030, from roughly 30 GW in 2015. The group comprises multiple companies in the industry, and reported a 13% drop
Photovoltaic system can have an efficiency of up to about 17%, while commercially available panels can go as far as 27%. It has been recorded that a group from The Fraunhofer Institute for Solar Energy Systems have created a cell that can reach 44.7% efficiency, which makes scientists' hopes of reaching the 50% efficiency threshold a lot more feasible. Photovoltaic cell electrical output is extremely sensitive to shading. The effects of this shading are well known. When even a small portion of a cell, module, or array is shaded, while the remainder is in sunlight, the output falls dramatically due to internal
