Perc monocrystalline dual glass solar panel / 305W / 60cells / 20V / white
solar panel is in high efficiency per space and can withstanding heavy snow and strong wind loads.
Compared with traditional non-flexible plates, the size is smaller and the weight is lighter,
Monocrystalline silicon technology in high performance.
It is waterproof and portable.
It can provides exceptional panel rigidity at reasonable price.
Main Features
1. Positive power tolerance(0~+5W) guranteed.
2. High module conversion efficiency, slower power degradation, enabled by rear passivation PERC technology.
3. Better energy yield with excellent low irradiance performance and temperature coefficient.
4. Glass/glass ensures 30 year product life span, with annual power degradation<0.5%.
5. Fire safety Class A.
6. Adaptable to harsh enviroment.
