No — an inverter isn't needed just to charge a battery. You'll only need one if you plan to run AC appliances like a TV or refrigerator directly off the battery.
Yes — cooler temperatures can actually improve panel performance. Just keep it clear of snow buildup, shade, or other obstructions to maintain output.
No, as long as a solar charge controller is installed in the system — it prevents reverse current from flowing back into the battery after dark.
It carries a 25-year performance warranty: at least 95% of rated output after 5 years, 90% after 10 years, and 80% after 25 years.
The MEGA 100 is available in Silver or Onyx (Black) finish.

I installed 8 RS100 panels in 2022, noticed that 4 of those panels had burn spots in 2025, and Rich Solar replaced those 4 panels with 4 of the new-design MEGA 100 panels. The mechanical specs of the new panels changed slightly, but you can see in the included pictures that the new MEGA 100 panels (in the foreground of the pic of the glass side of the panels) were able to be installed on the same frame I'd designed and built for the RS100 panels.

It was exactly what I needed. Came very fast to my ranch. Easy to install.

I have a small hunting shack on a section of my farm where there is no electricity. The Rich 100 watt panel keeps an AGM 100 amp battery charged and powers overhead DC bulbs as well as a bed lamp, security camera and monitor, and small 15” TV ready to use. I use the Rich 20 amp mppt charge controller. I have enjoyed that combination that has allowed me to stay down there and have a bit of comfort.

Replaced old technology 400w with 600w of Rich Solar panels and doubled my output !
