The solar photovoltaic power generation system mainly consists of photovoltaic arrays and other system components, including a charge controller or inverter, distribution cables, switchgear, and lightning protection devices. The inverter converts the direct current output from the solar photovoltaic panel array into alternating current. Isolation transformers installed inside or outside the inverter help ensure the safe operation of the system.
Solar power generation systems connected to the grid primarily connect indirectly to the grid, while the alternating current output of the solar power generation systems in the site or building is connected to the local distribution system, supplying power simultaneously with the grid to meet the electricity needs of the site or building without the need for batteries.
The amount of solar power generated is influenced by the principles of solar panels, and several factors can affect energy production and efficiency. Here are two main factors:
Sunlight is affected by the weather. Poor weather such as cloudy days, rain, or fog can significantly reduce the intensity of sunlight, thereby impacting the efficiency of solar panels. Additionally, seasonal changes can also affect sunlight, as the variation in the sun's angle can lead to differences in the duration and intensity of sunlight across different seasons. Typically, summer has longer daylight hours and ample sunlight, while winter has shorter daylight hours and relatively weaker sunlight. Moreover, geographic location also affects sunlight. The latitude and longitude of a region determine the amount and intensity of solar radiation received locally. Areas closer to the equator generally receive more sunlight, which is favorable for solar energy generation.
The principle of solar panels mainly depends on the power of the solar panel, which refers to its efficiency in converting solar energy into electricity. The power of solar panels is determined by multiple factors, including: materials and technology as well as maintenance conditions. Different materials and technologies lead to different efficiencies in solar panels, and some high-efficiency panels can still generate more electricity under low light conditions. We BW Green Power offer two types of solar panels with power ratings of 440W and 575W.
