On July 27th, I visited Goyozan Solar Project site in Iwate, Japan. The solar farm directly supplies 16 MW (Maximum output) to the local grid without the use of energy storage. In the site, we discussed the common issues/problem with the project, which includes panels efficiency, materials used, lifetime, recycling of panels, tariffs and cleaning. The visit comes as part of MiSK global leadership program for sustainable energy systems.
