1.Solar panels: from 5W to 310W
2.Solar panel warranty: output power is not less than 90% within 10 years and more than 80% within 25 years.
3. Our solar modules have passed many certificates like TUV, CE, ROHS, ISO, IECetc.
4. Cost of photovoltaic modules: We can get best prices by giving large orders to solar photovoltaic cells and raw material suppliers .
5. Solar cell technology: either Mono-Si or Poly-Si is available.
6. Solar panel efficiency: not less than 15%
7. Power torlerance of PV modules: ± 3%
8. Overall quality of our soalr panels: Tidy joined, anodized corners and aluminum frames make our photovoltaic modules more time consuming.
9. Back sheet: With excellent strength, wether resistance, UV resistance and moisture barrier properties, the backing sheet is used to protect solar cells of photovoltaic modules.
10. Reasonable mumbers of all temperature coefficients.
