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 your 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.
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%.
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.
Will my system still generate power during a blackout?
For an off-grid system, the solar panels with continue to generate power as long as the sun is still out
How much maintenance is required?
We recommend cleaning the solar panels on a weekly or bi-weekly basis in order to keep their performance high.
What voltage are your panels? Will they work with my 12V, 24V or 48V system?
We have nominal 12V and 24V panels. These panels actually produce 20+V and 30+V, respectively. Whether it will work with a 12V, 24V, and 48V will depend on the controller that you use. All the controllers we offer will work with 12/24V systems.
