The Mega150 panels were the right size while giving more output than other options. Customer support has been excellent. Perfect size for rv and van.

These panels appear to be well made. I had four 80w panels that were quite old and had become degraded so adding four 15w panels probably doubles my practical output. Their price was good and with free shipping a deal. They shipped promptly. I’d recommend this company.

I needed to upgrade my solar system at our remote cabin. These 2 150W panels, wired in Series, provide all the juice needed to keep our 600ah battery bank very satisfied. Wiring was easy. Thank you, Rich Solar, for the product advice. I am quite satisfied.

Panel met expectations, packaging protected it despite UPS leaving a giant boot print right in the middle of the panel.
Good Quality
works well
I already had two panels of 200 watts each but not sufficient amps for six 100ah batteries, had to buy this panel to hopefully keep them charged at a better rate. A two hundred watt panel will not charge at two hundred watts I don’t know why they’re called that and don’t put out. Between both totaling four hundred watts at maximum sunlight I they only charge at about 310 watts, I’m hoping that the 150 additional watts will be sufficient. Please advise, I am satisfied with them just don’t understand why they’re called 200watts and won’t deliver
Great product and customer service. I will definitely purchase from Rich Solar again
Rich solar panels are a vital part of my remote maple syrup production, dc pump batteries are recharged with the solar panels for non-stop production. This Rich solar panel was purchased to place my fourth DC maple syrup pump into production in 2026. Thanks for a fine product.
Christina was great to work with! Panels came quickly.
I have been using Rich Solar panels in my Maple syrup business for two years. The panels are used to charge batteries for pumps deep in the woods. The Rich panels perform great
These are fantastic panels for smaller installations. We put one on a customer's camper van and two on another customer's pickup bed cap.
I use this to recharge a portable solar generator which I then use to provide power in remote areas of my property when needed and to provide at least some emergency power when my grid system isn't functioning, I secured it to a steel platform about two feet off the ground. Works really well for my purposes.

Good price, fast shipping, extra cardboard on surface saved one panel from shipping damage.

The panels in full sun are producing almost 12 amps of power. On an overcast day they still produce .2-.5 amps of power! Would recommend for product performance and customer service. One panel came damaged and they sent a replacement immediately so I had it before my camping trip.

This solar panel has several advantages making it a great purchase for charging our travel trailer batteries. This panel was a replacement for a panel that was broken It is compatible with the controller that was installed in the trailer at an earlier date. It keeps two 6V batteries fully charged while dry camping without the noise, weight, fuel needs and smell of a generator. It is light enough for a 65 year-old woman to move in and out of the trailer and around the campsite. It is NOT made in China, but in Vietnam. Made in the USA would have been better, but it is difficult to find panels this size and with this charging capacity that are made in the USA. The price was very reasonable and shipping and packing were well done to insure the panel arrived undamaged.

three panels on a sailboat, lights, electronics, and watermaker kept batteries at 90% plus I replaced four 130 watt panels that were over 8 years old from the previous owner. Being on a mono-hull sailboat, there is limited wiring options, so I went for a series set. I have a Victon 100/50 MPPT controller and I say 540 watts at times. My batteries got down to 85 percent when we had two overcast days. The panels are pretty efficient even on overcast days. I recommend these panels for marine environment where they are not getting green water over them. Splashes, wind, and rain did not phase them.
