Solar photovoltaic power generation need comprehensive consideration of various factors, only master the accurate information, can determine the panels installation, low power and specifications ( Solar panels are effective capacity every day must be too in load power consumption) And battery
solar photovoltaic power generation need comprehensive consideration of various factors. Only master the accurate data, to determine the installation method, minimum power of the battery, specification ( Solar panels of effective capacity must be greater than the load power consumption) And the way the capacity, performance, and control. Make the product the best price. If the estimate of the related factors, will directly affect the independent photovoltaic power generation system performance and cost. ( 1) The geographical location of site. Include: location, latitude and longitude, altitude, etc. ( 2) Install the scene of the meteorological conditions. Total solar radiation, direct radiation (including month Or the sunshine percentage) , the annual average temperature, the longest continuous rainy days, the maximum wind speed, hail, snow and other special weather conditions. ( 3) The maximum load. Including daily working hours and average power consumption load, as well as the continuous rainy days of working time. ( 4) Load power consumption characteristics due to the solar array output current to direct current (dc), if the load for alternating current (ac), may need to be done by inverter transformation to work properly, so eventually provided to the load of solar energy loss will increase, so the solar cells will increase, will increase the cost of solar power supply system. ( 5) Ac load demand for power supply in addition to need more solar panels, ac load also need different inverter, depending on the load. In general, such as heating wire pure resistive load to the requirements of the inverter is not high, so you can use the ordinary modified wave inverter. However, TV and need a relatively high power electric motor, and requires high inverter power and output characteristic. Power sine inverter is needed to ensure that the load can work normally and without interference. Cost due to different load requirements. ( 6) Use restrictions due to some countries and regions have specific environment request for battery, especially the nickel cadmium battery tightly restricted in Europe and the lead-acid battery is restricted in the transport sector, all of these factors will lead to the increased cost of solar photovoltaic products.
