High efficiency 305W photovoltaic polycrystalline solar panel 



300W 305W 310W 315W solar PV module for solar home system.

Solar energy products are a trend and good way to achieve zero home bills or commercial invest in the future. So choose a good solar panel is important.The key factors to consider when comparing solar panels are performance ( they should produce the power that the rating leads you to expect), quality, durability and beneficial warranty terms.


Quality and Warranty
