Here's to give you popularity!
How to choose the grid-connected voltage of distributed photovoltaic grid-connected system?
A: The grid-connected voltage of the distributed photovoltaic system is mainly determined by the installed capacity of the system. The specific grid-connected voltage must be determined in accordance with the access system of the grid company. In general, households use 220V to access the grid, and commercials choose 380V to access the grid.
What determines the tilt angle of the PV array?

Due to the installation conditions, the inclination angle of the component installation can not be optimized and the angle can be properly adjusted.
How to determine the installation orientation of the PV array? What is the effect on power generation? Answer: Since the main reason for photovoltaic power generation is the amount of solar radiation, the components should be installed in the direction with the best sunlight. Different installation angles also affect the power generation efficiency of photovoltaic modules.
How to choose PV modules?
A: According to the specific conditions of the installation site, different types of PV modules can be used. The effective area of ​​the installation site determines the size of the module. If you want to install a larger capacity within the unit area, you can use a high-efficiency module according to the existing building. Appearance can also choose different border color components, according to the site of the serial connection line to determine the length of the connector component. The selection of components requires a comprehensive consideration of the installation area, installed capacity, and cost factors. In general, components with good reputation, good quality, certification, and good after-sales service should be selected.
