solar photovoltaic power generation is increasingly becoming an important form of electricity generation, is accepted by more and more people. More and more people are installed photovoltaic power station. So what is a photovoltaic power generation? Photovoltaic power generation system is a kind of use solar cells convert solar energy directly into electrical energy power generation system. Household solar power generation system consists of solar battery, solar controller and the battery ( Group) Composition. If the output power to 220 v or 110 v ac, also need a inverter. What are the advantages and disadvantages of household solar power system? Advantages: 1, the inexhaustible solar energy, solar power safe and reliable, not suffer from electricity crisis or fuel market is not stable; 2, the solar energy is everywhere, nearby power supply, without long distance transmission, avoid long distance transmission line loss; 3. Solar power without operating unit, without damage, simple maintenance, especially suitable for unattended. 4, solar power does not produce any waste, no pollution, noise pollution, no adverse effects to the environment; 5. Solar doesn't need fuel, operation cost is low. 1. The energy density is low. Under normal circumstances, the solar radiation intensity of ground receiving 1000 w/m2. When the mass use of demand occupy large area; 2. Intermittent and random use, power generation and climate conditions, power generation in darkness or little or no rain; 3. Offer relatively expensive, 3 ~ 15 times that of conventional power generation, high initial investment. However, in the present circumstances, solar photovoltaic power generation has become a trend, it can be for personal use, also can use the rest of the power connected to the Internet.
