How to calculate the output power of solar cell

Solar panels are made of solar cells in series parallel, one square metre of panels with different batteries, series-parallel have different combinations. Solar ac power system consists of solar panel, charge controller, inverter, and battery common

solar panels composed of series and parallel solar panels. A square meter panel using different panel, and a different combination of series and parallel. Solar ac power system by the solar panel, charge controller, inverter and battery. Solar energy does not include the inverter DC power system. In order to make the solar power system can provide enough power for the load, it is necessary to choose various parts according to electric power reasonably. Let's new energy to hotan 170 watts of monocrystalline silicon solar panels as an example, with 170 w power output, 6 hours a day, for example, to introduce calculation methods: 1. First of all, should calculate daily consumption watt hours ( Including the inverter loss) : if the inverter conversion efficiency of 90%, when the output power is 170 w, the actual need of the output should be 170 w / 90% = 188 watts; If use 6 hours a day, power consumption is 188 * 6 h = 1128 watts. 2. The calculation of solar panels, solar panels, the output power of 1128 watts / 6 hours / 70% = 268 watts, based on the effective sunshine time of 6 hours a day, and consider the loss during the charging efficiency and charging. 70% of which is the real power of the solar panels are used in the process of charging. More than just to hotan new energy 170 watts of monocrystalline silicon solar panels as an example for reference only. The specific calculation should be based on your actual needs. The company have more other types of solar panels used in different areas, more professionals will be tailored for you according to your need. If you want to buy car solar panels, and new energy sources will provide you with one-stop purchase, installation and after-sales service. You are welcome to inquire.
