FAQ

Common Questions

How is the MEGA 250 more compact than other 250W panels?

Its half-cut, 16-busbar cell design and split-energy layout pack the same 250W output into a footprint about 10% smaller than standard 10BB 250W panels — a real advantage on tight RV, van, or trailer roofs.

Can it survive hail and severe weather?

It's rated for 2,400 Pa wind loads and 5,400 Pa snow loads, and is impact-resistant against hail up to 35mm at 97 km/h.

Do I need an inverter if I only want to charge my battery?

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.

How long will the panel last?

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.

What color options are available?

The MEGA 250 is available in Silver or Onyx (Black) finish.

When I visited their headquarters, the staff was very friendly and helpful. A sales associate discussed my needs with me and recommended a 130W slim panel. He showed me several sizes that would fit over my truck, and the 130W option seemed to be the best fit.

I've been using the 130W panel with a 100Ah lithium battery and a 21Q 12V refrigerator for a few months now.
The battery stays fully charged, and I never run out of power.
Even on a 4-day trip using an 80Q refrigerator, the single battery ...

Rich Solar was great. I called customer service pre-sale and they were responsive and fully answered my questions. Shipping timing was great and post sale service was awesome.

One of the 10 panels purchased arrived broken.
Rich Solar replaced it and made the process easy with quick turnaround!
This was my first purchase with them and the experience was a pleasure.
