On-Grid Systems tie directly to your utility grid, offering an alternative source of energy in addition to what your utility company provides. By utilizing on-grid solar systems, you can greatly or completely reduce your electricity bill. In addition, depending on the size of your on-grid system, you may receive monetary returns.

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. Common off-grid applications include cabins, Off-Grid vehicles, boats, and dry camping. Off-grid systems can also be used in a variety of other applications, including emergency power backup during a power outage.

There is a difference in the manufacturing technique, and as a result monocrystalline cells are more efficient. The monocrystalline cells can produce more power in a smaller space. Also, monocrystalline panels have a darker blue color, almost appearing black, and are usually higher in price due to the increased efficiency. Polycrystalline panels on the other hand are less efficient and require more space. However, the difference is size and efficiency do not impact power. A 100 Watt monocrystalline panel and a 100 Watt polycrystalline panel will both output 100 Watts, neglecting power loss in the system, but a monocrystalline panel will output 100 watts with a smaller surface area.

Renogy Framed 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%.

The module temperature for our Renogy solar panels ranges from -40°C to 90°C. Whereas our charge controllers have an operating temperature of -35°C to 55°C. The majority of our solar panel are water proof and do fare well in extreme conditions however, our charge controllers are not water proof. We recommend storing and securing the charge controller in a well ventilated dry space.

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.

We recommend cleaning the solar panels on a weekly or bi-weekly basis in order to keep their performance high.

For an off-grid system, the solar panels with continue to generate power as long as the sun is still out.

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. The MidNite Classic controllers will work with 48V systems.

Framed/Rigid panels 10w-150w (mono and poly) is 25 Year Transferable Power Output Warranty and 5 Year Material and Workmanship Warranty.

Framed/Rigid panels 240w-300w (mono and poly) is 25 Year Transferable Power Output Warranty.

Lightweight panel 50w and 100w is 3 Year Material Warranty.
