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.

300W 305W 310W Poly Solar Panel Characteristics
1) high reliability with guaranteed +/-3% output power tolerance
2) The modules can withstand high wind-pressure,snow loads and extreme temperatures
3) Bypass diodes to minimize power loss with shading
4) High and stable conversion efficiency to ensure the highest quality
