Editor's note: recently, the photovoltaic system energy recovery cycle is calculated results released, for 25 years in the service life of the photovoltaic power station under the premise of photovoltaic system energy recovery cycle is zero. 58 years.
photovoltaic (pv) is the main clean energy, is to realize the energy transformation of powerhouse. Over the years, there are still some misunderstandings, however, think that photovoltaics will spend a lot of energy, a large amount of carbon dioxide emissions.
the deputy secretary-general of the national federation of industry and new energy chamber of commerce, crystalline silicon photovoltaic (pv) branch of the secretary-general Shi Limin sponsored by the national federation of industry and new energy chamber of commerce in the 2020 China international new energy released at the annual meeting of the pv system research on energy recovery cycle is calculated results, photovoltaic (pv) grid, solar power network, for photovoltaic power generation.
Shi Limin, said energy payback period is equal to the whole life cycle of photovoltaic power generation system of the total consumption annual energy output divided by the pv system, solar portal, namely photovoltaic system energy payback period is equal to the manufacture, installation and transportation process of the total energy consumption capacity of system life. And photovoltaic system energy consumption depends on the technical level and production operation management ability, solar energy, photovoltaic power system depends on the system configuration, installation position and way, local solar energy resources condition, operational level, etc.
according to the calculation, for 25 years in the service life of the photovoltaic power station under the premise of photovoltaic system energy recovery cycle is zero. 58 years, solar panels, photovoltaic power station are of great value in environmental protection and energy yield.
