The solar energy principle in all parts of the solar photovoltaic power generation systems

Solar photovoltaic power generation system consists of solar battery, solar controller, battery ( Group) Composition. Such as the output power for ac 220 v or 110 v, also need to configure the inverter. The role of each part as follows: ( A) Solar panel: solar electricity

solar photovoltaic 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. The role of each part is: ( 1) Solar panel: solar panel is the core part of the solar system, was a high value part of the solar system. Its function is to convert the sun's radiation ability into electrical energy, or store it into the battery, or promote work load. ( 2) Solar controller: solar controller's function is to control the working state of the whole system, prevent the battery overcharge and over discharge. In difference in temperature big place, qualified controller should also has temperature compensation function. Other additional features, such as light control and time control switch should be the optional features of the controller. ( 3) Battery: normally lead-acid battery, nickel metal hydride batteries, nickel-cadmium batteries or lithium batteries can also be used for small and micro system. Its function is when there is light store electric energy from solar panels, and released when needed. ( 4) Direct output of inverter, solar energy is usually 12 VDC and 24 VDC and 48 VDC. To 220 volts ac power supply, need to convert solar power generation system to produce direct current (DC) to alternating current (ac), so you need to use DC ac inverter. Factors to consider in the design of solar photovoltaic power generation systems. 1. Where is the use solar power system? How is the area of solar radiation? 2. How much is the load power system? 3. How much is the output voltage in the system, DC or ac? The system need to work how many hours a day? 5. In the rainy days without sunshine, the system need how many days of continuous power supply? 6, load, pure resistance, or inductance, the starting current?
