Factory Poly Solar Panel 250W 300W for Home Solar pv Module

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 25th 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

Features of solar panel

Polycrystalline or Monocrystalline silicon is a material consisting of thin wafers that are cut from a silicon crystal which has grown in several directions. This advanced texturing process provides polycrystalline or moncrystalline solar panels with a higher power output than amorphous panels of the same dimensions, and makes them more cost and space-effective. These individual wafers are assembled into panels that are covered by durable, weatherproof tempered glass. Thanks to their efficiency and durability, these solar panels require virtually no maintenance once installed.

Solar panel is super energy saving and makes people life happy

Solar panel helps us to take full advantage of solar energy which is clean, inexhautible and pollution-free, and it converts sunlight into electric. In this way, we can help people in remote areas without mains supply and lack of electricity, and light up nights and bring people hope there.
