400 watt Mono Solar Panel Specification
The 400 watt Mono solar panel is specially designed for home photovoltaic systems. It can be installed on level ground, metal roofs and tiled roofs. It outputs 48V DC and can be connected to a PV charge controller to charge the solar batteries, or to a PV inverter to output AC power for use by the load or for transmission to the city grid.

400 watt Mono Solar Panel Features
20.54% PV module efficiency: Maximizes the use of raw materials for PV panels, which is a significant improvement over polycrystalline PV modules with only 13% efficiency.
Aluminium alloy frame: more stable structure, no rust, strong corrosion resistance.
Good performance in low-light environment: it can also generate a small amount of electricity on cloudy and rainy days or in the morning when the sun is not very strong.
Salt fog resistant performance: it will not be affected in areas where salt fog becomes high, such as seashore and islands, and can easily cope with a variety of complex environments.
Warranty service: 25-year power attenuation warranty, and the annual power attenuation rate is less than 1%.
Good performance in shaded environments: The bypass diode enhances the overall power generation efficiency when the PV panel is shaded.
