Choose PV modules according to the specific conditions of the installation site. The effective usable area of the installation site determines the specification and size of the modules. If you want to install more capacity per unit area, high-efficiency modules can be selected. According to the appearance of the existing building, modules with different frame colors can also be selected. The connector length of the modules is determined according to the series-parallel wiring method on site.
The selection of modules should comprehensively consider factors such as installation area, installed capacity and cost. Generally speaking, module products from manufacturers with good reputation, good quality, certification, warranty and good after-sales service should be selected.
