Factors affecting the efficiency of solar photovoltaic power generation

1. The influence of natural conditions

①The influence of solar altitude and geographic latitude

The solar altitude can directly affect the solar radiation intensity. In areas with high latitudes, the sun's altitude angle will be smaller and the sun's radiation intensity will be weaker; in areas with low latitudes, the sun's altitude angle will be greater, so that the sun's radiation intensity will be stronger. Therefore, in areas with low latitudes, the advantages of solar photovoltaic power generation are more prominent.

②The influence of atmospheric transparency and altitude

Atmospheric transparency is a parameter of sunlight passing through the atmosphere. When the sky is clear, the transparency of the atmosphere is very high, and the radiation of sunlight on the ground will be stronger, and vice versa. The higher the altitude, the thinner the air and the higher the transparency of the atmosphere. Therefore, the higher the altitude, the greater the solar radiation energy.

③The influence of sunshine hours

The sunshine hours is also an important factor affecting the efficiency of solar power generation. Generally, if the sunshine time is long, the total solar radiation received by the ground is more. Then the more solar energy absorbed by solar photovoltaic, the more electricity stored.

2. The impact of inverter efficiency on power generation efficiency

When the high-power inverter is fully loaded, the efficiency must be more than 90%. Especially when power is supplied under low load, higher efficiency is still required. The efficiency of the inverter has an important influence on the solar photovoltaic power generation system to increase the effective power generation and reduce the power generation cost.

In the design and selection of the inverter, special attention should be paid to its own power loss to improve the efficiency of the whole machine. Therefore, in order to improve the output efficiency, a high-quality inverter type must be selected.
