Solar Panel Application
Longi 635- 670W modules are suitable for projects that pursue high power generation and low electricity costs due to their N-type technology and high power density. When selecting a model, it is necessary to comprehensively evaluate the local lighting conditions, installation environment, and supporting system compatibility. If the budget is sufficient and the site allows, this model is an efficient and reliable choice.
