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

For a period of twenty‐five (25)years commencing on the Warranty Start Date, loss of power output of the nominal power output measured at Standard Test Conditions (STC) for the Product(s) shall not exceed:
For Polycrystalline A grade solar cell, 3% in the first year, thereafter 0.66% per year, ending with 81% in the 25 th year after the Warranty Start Date;
The Warranty Start Date shall be defined as the date of the Bill of Lading date
10Years Manufacturing Warranty
15Years Warranty 90% Power Output
25Years Warranty 85% Power Output
