The rated power of photovoltaic panels is 315 watts, which means that a solar panel power generation system with an installed capacity of 315w generally uses W to describe the model of photovoltaic panels on the market. the most common ones on the market are around 260W to 315W. 1000W is equivalent to 1KW. 10KW is equivalent to approximately 38 260W boards. The area of a single board is approximately 1 meter by 1.65 meters, or 1.65 square meters, and 1KW is equivalent to 1 kilowatt hour of electricity per hour.
The use of photovoltaic panels with a nominal power of 315 watts
If there are 7 to 8 hours of sunshine that day, it will in fact be 60 kilowatt hours of electricity. But on average, including rain and cloudy days, the annual average is only 4 hours. Solar panels are devices that absorb sunlight and convert radiation energysolar directly or indirectly into electrical energy by photoelectric effect or photochemical effect. The main material of most solar panels is silicon, but the production cost is high.
If it's a 10 kilowatt solar panel, it can theoretically generate 10 kilowatt hours of electricity per hour, but many factors actually affect it. When the sun shines that day, the electricity from the solar panels must be converted by the inverter into 200V household electricity before it can be used. There will be losses in the process, usually 25-30%. The sunshine in southern China is generally such that a 10 kW solar panel can produce 26 kilowatt hours of electricity per day.
