Business model and the types of applications related to PV, PV market into a separate classification of photovoltaic systems and photovoltaic systems and grid-connected photovoltaic power generation system. Independent photovoltaic power generation system is divided into micro-grid rural electrification, communications and industrial applications, and decentralized use of photovoltaic products. Grid-connected PV power generation system consists of distributed PV systems and building large-scale photovoltaic power plants. Use the PV system can take much for me to save? A conversion efficiency of 10% of the PV system, electricity can be issued about 180 per square meter in the area. Rated power of 1 kW photovoltaic system photovoltaic power generation, power generation per year is about 1800 degrees. Allow annual loss of efficiency in photovoltaic installed by less than 1%, so that a system can power nearly 36 PV efficiency in 20 years, 000-degree photovoltaic prices in 30 years is to generate electricity 54,000 degrees. This means that in 30 years, the PV system sends electricity worth about $ 10,000. In many countries, solar power can enjoy the preferential price, and offer tax breaks and other favorable conditions, thereby improving the economic performance of photovoltaic power generation.
