How PV Capacity is Determined
Several factors contribute to the determination of PV capacity. Firstly, the solar panel efficiency plays a crucial role. Higher efficiency panels can convert a greater amount of sunlight into electricity, resulting in a higher capacity. Secondly, sunlight intensity is another important factor. Areas with high solar irradiance receive more sunlight energy, leading to increased PV capacity. Additionally, temperature also affects PV capacity, as hotter temperatures can reduce panel efficiency. Lastly, shading from trees, buildings, or other obstructions can impact the amount of sunlight reaching the panels, lowering the overall capacity of the system.
| Factors | Impact on PV Capacity |
|---|---|
| Solar Panel Efficiency | Higher efficiency leads to increased capacity |
| Sunlight Intensity | Higher intensity results in greater PV capacity |
| Temperature | Hotter temperatures can reduce panel efficiency and lower capacity |
| Shading | Obstructions can reduce sunlight reaching the panels, decreasing capacity |
Benefits of Understanding PV Capacity
