It can generate approximately 244.8 kilowatt hours per day.
Generally speaking, the amount of energy that a 68 kilowatt photovoltaic power generation system can produce in a day depends on the intensity of solar radiation at the location . Solar radiation intensity refers to the energy of the sun per unit area. The intensity of solar radiation is related to geographic location, season, weather conditions and other factors.
Taking southern China as an example, the intensity of solar radiation in summer is relatively high, generally around 1,000 watts/square meter. Let us assume that the efficiency of the photovoltaic panel is 15%, that is, the proportion of light energy that can be converted into electrical energy is 15%. Then, the amount of electricity that a 68 kilowatt photovoltaic power generation system can generate in a day is approximately : 68 kilowatts × 15% × 1,000 watts/square meter × 24 hours = 244.8 kilowatt hours
Converted to units of electrical energy, or 244.8 kilowatt hours. This value is an estimate and the actual electricity production will also be affected by other factors, such as weather conditions, cleanliness of photovoltaic panels, etc.
