1. The inclination degree of photovoltaic module installation
The azimuth angle of photovoltaic modules is generally chosen in the south direction to maximize the power generation per unit capacity of the photovoltaic power station. As long as it is within ± 20 ° due south, it will not have a significant impact on power generation. If conditions permit, it should be as southwest as possible by 20 °.

2. Efficiency and quality of photovoltaic modules
Calculation formula: Theoretical power generation=Annual solar radiation x Installed capacity x System efficiency
There are two factors involved, battery area and photoelectric conversion efficiency, which have a direct impact on the power generation of the power station.

Component matching loss
Any series connection will cause current loss due to differences in component currents, while any parallel connection will cause voltage loss due to differences in component voltages. The loss may reach over 8%.

Ensure good ventilation conditions for components
Data introduction: When the temperature rises by 1 ℃, the power of crystalline silicon photovoltaic modules decreases by about 0.3%. So it is necessary to avoid the influence of temperature on power generation and maintain good ventilation conditions.

The loss of dust should not be underestimated
The panel of the crystalline silicon module is made of tempered glass, which will naturally accumulate organic matter and a large amount of dust when exposed to the air for a long time. Surface dust blocking light can reduce the output efficiency of components and directly affect power generation.

At the same time, it may also cause the "hot spot" effect of components, leading to component damage. Rainwater can be cleaned without special maintenance. If you encounter attached dirt, simply wipe it off.

3. Reduce line losses
In photovoltaic systems, cables account for a small portion, but their impact on power generation cannot be ignored. It is recommended to control the line loss of DC and AC circuits within 5%.

The cables in the system should be well insulated, heat-resistant and flame-retardant, moisture-proof and light proof, type of cable core, and size specifications of the cables.
