PV systems can use saved me how much to spend? A conversion efficiency of 10% of the photovoltaic system that can emit electrical 180 degrees per square meter in the area. Rated power of 1 kW photovoltaic system PV power plant per year generating about 1800 degrees. Under allow annual efficiency losses of less than 1%, such a system can generate nearly 36,000 degrees in 20 years, in 30 years, but can generate 54,000 degrees. This means that in 30 years, the photovoltaic system sends electricity worth about $ 10,000. In many countries, solar power can enjoy the preferential prices, and provide other concessions and tax incentives photovoltaic join, thus improving the economic performance of photovoltaic power generation. The business model of international experience in the international arena for distributed PV systems used incentives or business model there are three kinds: "Tariff" (Feed-inTariff photovoltaic applications, FIT) policy, "net power settlement" (NetMetering) policy, and "self-consumption" (Self-Consumption) policy. PV generator | TIANHUI solar power (certified) | Wuhan photovoltaic provided by Wuhan days Hui Technology Co., Ltd. giant. Wuhan Tian Hui Ju Technology Co., Ltd.
