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.
250W 300W 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

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.
