Publication of design guidelines for solar power generation slopes and agricultural lands

Regarding "solar power generation," which is one of the renewable energies that the national government places the highest priority on the realization of a carbon-free society, design guidelines have been compiled to reduce damage to power generation facilities due to typhoons, etc. The design and construction methods in special environments have been materialized.

The introduction of "solar power generation" has expanded rapidly since the feed-in tariff system for renewable energy that started in 2012 after the Great East Japan Earthquake, but it is safe because the equipment is damaged one after another due to natural disasters such as typhoons and heavy rains. Ensuring sex is one of the challenges.

In recent years, slopes, agricultural lands, and equipment on the water, which are being installed more and more, have also been damaged, so guidelines that specifically describe precautions for design and construction in such special environments have been compiled and published. ..

Of these, in the case of installation on slopes, it is necessary to conduct a ground survey in advance to prevent the outflow of earth and sand, and to protect the slope and install drainage facilities in consideration of the regulations of the local government. ..

Also, in the case of agricultural land, it is important to take measures to prevent chain collapse due to collision of agricultural machines such as cultivators and to protect cables to prevent electric shock. It is required to fix it after assuming the force.

NEDO = Senior Researcher Mitsuhiro Yamazaki of the New Energy and Industrial Technology Development Organization, who summarized the guidelines, said, "In order to popularize photovoltaic power generation, it is necessary not only to reduce costs but also to improve safety and reliability. I would like you to use this as a reference for designing so that you can contribute to the reduction of carbon dioxide. "

The Ministry of Economy, Trade and Industry is considering the guidelines with the intention of incorporating them as guidelines for the technical standards for "solar power generation" within this fiscal year.
