The analysis of the photovoltaic modules is the core of influence power factor

Photovoltaic component installation Angle of photovoltaic module is the core factors affecting capacity, photovoltaic modules the conversion rate of the high power, the better the results. Photovoltaic modules installed solar radiation Angle and direction to face, the installation Angle is generally local latitude

photovoltaic component installation Angle of photovoltaic module is the core of influence power factor. Photovoltaic conversion rate is higher, the module of power the better the results. Installing a photovoltaic modules, solar radiation Angle and direction should try to face. Usually 5 degrees latitude and local installation Angle, installation Angle is usually south by west. Inverter voltage range of inverter voltage range is wide, the higher the output. In outdoor installation, inverter should be equipped with rain and sun protection cover, to avoid direct sunlight and rain water. Inverter is not directly exposed to the sun or other sources of heat. Inverter must be placed on the air circulation in the empty room. Inverter is divided into forced air cooling and natural cooling. Inverter is in itself a source of heat. All heat must be send out in time, not in the empty room, closed, otherwise the temperature will be more and more high. System configuration standardization of photovoltaic power station system configuration is pieced together, possible component is good also, but the stitching effect is greatly reduced. A standardized system must go through many times of matching test, data comparison, system debugging and installation of demo, can achieve stable power generation capacity. This system is known as standardization system. Reduce the loss of line loss, photovoltaic DC lines as short as possible, inverter and the distance between the meter should be as short as possible. System of DC and ac circuit line loss should be controlled within 5%. Design, therefore, should use electrical conductivity good conductor, the diameter of the conductor should be enough. Not allowed to cut corners during construction. During the system maintenance, should pay special attention to the connector and wiring terminals are strong. Any series power plant dust loss portfolio losses, will loss caused by components of current differential current; Any parallel voltage loss caused by the voltage difference between the components. Comprehensive loss could reach more than 8%, China engineering construction standardization association standards is less than 10%. In order to reduce the loss of comprehensive, power station before installation should strictly choose current components in series. Consistent attenuation characteristics of components as much as possible. According to the national standard GB/T - After 9535, under prescribed conditions test, big output power attenuation solar battery components shall not be more than 8%. Isolation diodes are sometimes necessary.
