1.Solar panels: from 3W 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, MCS, ISO9001, IEC61215 and IEC61730 etc.
4. Cost of photovoltaic modules: We can get best prices by giving large orders to solar photovoltaic cells and raw material suppliers .
5. We, Joysolar, are a professional manufacturer of solar kits and have gained great reputation in China and abroad.
6. Solar cell technology: either Mono-Si or Poly-Si is available.
7. Solar panel efficiency: not less than 15%
8. Power torlerance of PV modules: ± 3%
9. Overall quality of our soalr panels: Tidy joined, anodized corners and aluminum frames make our photovoltaic modules more time consuming.
10. 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.
11. Reasonable mumbers of all temperature coefficients.
