Hello: I can understand your question about whether there is a relationship between photovoltaic energy production and light intensity! In response to this question: The production of photovoltaic energy has a direct impact on solar irradiation, that is to say on light intensity. The greater the irradiation, the higher the electricity production! In addition, factors that affect the power generation level include component tilt angle, component conversion efficiency, shadows, losses, etc. I hope to adopt it!
How much electricity can one square meter of solar energy produce per hour?
You can query the hourly radiation data of any point or level of province/municipality, city, county/district in the world through the weather data platform.
Data SettingsHorizontal Surface Radiation: The total amount of radiussolar radiation incident on the horizontal unit surface of the earth
Direct radiation: refers to the solar disk and the area closest to the sun. (centered on the sun 5 Direct solar radiation emitted by the solar circle (degree of the sun)
Scattered radiation: refers to the diffusion of solar light when it encounters clouds, gas molecules, dust, etc. passing through the atmosphere and reaching the ground, and arrives in a diffuse form on the Earth's surface
Data source: Xihe Energy Big Data Platform ( xihe-).energy)
If you need to query more data, you can "Search for properties" in "More properties "
The efficiency of domestic crystalline silicon cells is about 10-13%, and that of similar foreign products is about 12-14%. For example: the average annual solar irradiation of Beijing est of 17 MJ/square meter/day. Assuming 6 hours of sunlight per day, the hourly irradiation is approximately 3 MJ/square meter/hour.
Only 10 to 14% of this amount is converted into electricity, which means that the electricity production per hour is (0.3 to 0.42) MJ, which is equivalent to (187 .5 to 262.5) W.
