How much electricity can a square meter of solar panel produce in one hour?

Currently, the efficiency of commercial photovoltaic solar panels can reach about 16%, which means that 16% of the solar energy obtained from one square meter can be converted into direct current. \r\n \r\nLight intensity varies greatly between regions, so the actual energy output of the same photovoltaic panels installed in different regions will also be very different. Taking the Shanghai area as an example, at noon from May to June, the solar intensity received per square meter is about 900 to 1,000 Wh. According to the 16% efficiency mentioned above, it can generate 150-160 Wh of electricity per square meter per hour. 1,000 Wh corresponds to one kilowatt hour of electricity. \r\n \r\nIf you have a 100 square meter roof, you can probably install 10 to 12 kW panels, which can generate around 40 kilowatt hours of electricity every day from May to June.
