Solar Panels Are Affected By These Factors

The inverter capacity ratio of the PV solar panel refers to the ratio of the rated power of the inverter to the capacity of the photovoltaic module. Since the power generation of photovoltaic modules is transmitted to the inverter, there will be many links in the middle that will cause reductions, and most of the equipment such as inverters and box transformers cannot achieve full-load operation. Therefore, the capacity of photovoltaic modules should be slightly larger than Inverter rated capacity.

Components connected in series and parallel matching Components connected in series will cause current loss due to the current difference of the components, and strings connected in parallel will cause voltage loss due to the voltage difference of the group strings.

Component shading includes dust shading, snow shading, weeds, trees, battery panels, and other buildings. Shading will reduce the amount of radiation received by the module and affect the heat dissipation of the module, resulting in a decrease in the output power of the module and may also cause heat dissipation. spot.

Module temperature characteristics As the temperature of crystalline silicon cells increases, the open circuit voltage decreases. In the range of 20-100 ° C, the voltage of each cell decreases by 2 mV for every 1 ° C increase; while the current increases slightly with the increase in temperature. In general, the power of the solar cell decreases as the temperature rises, and the typical power temperature coefficient is -0.35%/°C, that is, the power decreases by 0.35% for every 1°C increase in the battery temperature.
