PV photovoltaic products requirements (1) In order to maximize control and protection panels and battery life, in general reverse charge, overcharge, over-discharge protection circuit control, photovoltaic installation, to avoid damage to the battery plate and battery prematurely aging. (2) Due to the different parts choose solar photovoltaic products use environment, Castle photovoltaic power generation, the temperature difference between the larger, thus requiring parts to a wide operating temperature range. (3) maintain the photovoltaic system has no moving parts, photovoltaic agents, not easily damaged, Photovoltaic principle, its maintenance is very simple. But also need to do regular maintenance, it may affect the normal use, and even shorten life. PV relevant national energy policy Article IV State Council department in charge of the country distributed PV planning guidance and supervision; local energy authorities in charge of the energy sector under the guidance of the State Council, responsible for the area of ??distributed photovoltaic power generation planning, supervision and management of construction; National Energy Board the agency responsible for the area of ??distributed PV planning and policy implementation, and network operation, and a fair market operational safety supervision photovoltaic applications, Castle photovoltaic, solar day-by Wuhan days Hui Ju Technology Co., Ltd. .
