Will panels still charge on cloudy days?

This will also depend on the conditions. If it is cloudy and overcast, likely not. If it is cloudy and bright still, then it probably will charge but it won't be very much.

Product Q&A

Q:Are you a factory or trading company?

We are the factory which is specialized in producing all kinds of solar mounting systems for residential, commercial and utiliy.

Q:Where is your factory located?

Our factory is located in Xiamen city, Fujian province,China.

Q:What is the difference between on-grid and off-grid?

On-Grid Systems tie directly to your utility grid, selling an alternative source of energy in addition to what the utility company provides. Off-grid systems do not tie to the utility grid and are sustained using a battery bank. The battery bank can be hooked up to an inverter, which converts DC voltage to AC voltage allowing you to use any AC appliances or electronics.

Q:How long will PV modules last?

SunMaster Solar Panels have a performance warranty of 25 years. After 5 years they should output more than 95% of the rated power, after 10 years it is 90% and 25 years it is 80%.
