FAQ

Do l need to install an inverter if l only want to charge my boat or Rv battery with a solar panel?

You don’t need an inverter if you’re only charging your battery. However, if you want to use the battery to run different appliances, like a TV or a refrigerator, you need an inverter to convert the DC power to AC power.

Will solar panels work in the winter in my state or province?

Wherever there is sunlight, solar panels will generate electricity. Cooler conditions, like those during the winter, can help improve solar panel performance. Solar panels can still generate electricity in cloudy conditions, just not as efficiently. The panel won't generate any electricity if there is any snow build-up on it, so make sure to keep the panel clear. This goes for any type of obstruction including shade or dirt.

Does my solar panel system require roof penetration?

Solar panels don’t always need a roof penetration for installation. Most times, they can be permanently mounted on the roof using a sealant. Alternatively, they can be installed on the ground.

Can the solar panel drain my battery at night?

If you have a solar charge controller installed in your system, there is no danger of a reverse current draining your battery.

How long will the solar panels last?

The RICH SOLAR MEGA Series solar panels have a performance warranty of 25 years. After 5 years of use, the panels should output more than 95% of the rated power. After 10 years, that output is 90%, and after 25 years, the output should be 80%.

Can the solar module overcharge my battery?

Yes, but only if it’s used without the charge controller, which is why it’s important to always use one when you have a battery.

Can l run my 110V appliances with my solar power system?

Yes, you can run your 110V appliances with your solar power system using an inverter. The inverter connects your solar panel to your battery, converting the DC energy into AC energy, and allowing you to power your appliances.

How to avoid common mistakes in solar panel installation?

Shading: Avoid obstacles that block sunlight. Use shading analysis tools.

Improper Angle: Set panels at a 30–45° tilt facing true south for optimal efficiency.

Wrong Direction: Make sure panels directly face the sun.

Irregular Cleaning: Dirt reduces output—clean panels regularly with soft tools.

Mismatched Equipment: Use compatible panels, batteries, and inverters with matching specs.

Improper Connections: Use high-quality cables and ensure all connections are secure to prevent faults or fire.

Customer photo review of MEGA 100 | 100 Watt Solar Panel | Premier 12V Off-Grid Solar Panel for Vans, Campers, Boats | 25-Year Output Warranty | UL Certified

Rich Solar stands by their products! 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. Rich Solar Tech and Sales Support teams provided excellent service throughout the original sale and then during the follow-up to replace the RS100s. The quality of the service I experienced at Rich Solar is extremely hard to find!

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.

I recently ordered a BLUETTI EB200 with FOUR of these 100W Rich Solar Panels. My Solar Panels arrived quickly (about a week before I received my Solar Generator/Power Station). The Solar Panels were packaged very well. They had some very nice cardboard and foam "fittings" that secured the top and bottom of the panels, with some additional coverage in the middle. This was all placed inside a sturdy cardboard box for shipping. I inspected my panels immediately upon receiving them, and I was very pleased with their arrival condition. They are a good size. They are large enough to feel substantial, but small enough to feel "manageable." I am not in the greatest shape, but I could easily carry one of these panels up a ladder to install on a Shed, RV, or other structure. Additionally, these panels feel like they are made of good materials. They do not feel "cheap" when you touch them. The frame seems to be in a good, solid condition. It has nice holes in it for easy mounting, and although I am not "handy," I am beyond confident in my ability to do a good job installing this product. It is made in a way that you do not have to be an engineer to figure it out, or a carpenter to install it. It's set up in a very simple and straight-forward way. Also, I feel confident in my ability to hook this up to my system. I have a degree in Liberal Arts and also in Visual Art. I am NOT an "electrician" by any means. At first, I was intimidated by the concept of solar, wires, inverters, batteries, charge controllers, and so on. But this product and many of the systems on the market today are easy to understand and there are some great guides on YouTube that explain how to run these in Series, Parallel, or Series-Parallel. While I cannot give a "long term review," as I've only had the product for a little while, I can tell you that my first impression is GREAT! I feel confident enough in this product that I have already ordered four more, so that is a total of eight solar panels that I've now purchased from this company. I work as an advisor at a local Community College, and I make a modest salary. I would not have bought four more of these panels if I felt unsure about this investment. I personally believe this will suite my needs very well, and I have every intention of sticking with these panels for the foreseeable future.

I purchased two orders of Rich Solar 100 Watt solar panels. The first was for three panels and the second order was for one panel. I am pleased with my panels and have placed them on my south facing patio roof temporarily, until I can mount them more permanently. The panels are performing well and feed a portable solar generator, which runs a residential refrigerator, off grid. I plan on purchasing additional panels later this year, for when the days are shorter, during the winter months.

Rich Solar customer service is top notch! Got exactly what I needed after an inaccurate listing on their Amazon store as they were fast to make things right. In this day and age customer service is lacking in all industries but gladly these guys still get what it’s all about. I will be buying more products from Rich Solar as I’m just getting started on this RV off grid journey.

This purchase was to increase the number of panels in my array to four. I had purchased three panels in my initial order. This allows me to have two panels in series in parallel with two other panels in a separate series arrangement. I am pleased with this set up will be adding additional panels as I expand my system in the future. All four panels are performing as expected.

excellent solar brand I bought rich solar panels for several times, I realized that they improved the quality each time, my first order arrived with poor packing box, I worried about the quality at that time, when I see the solar panel, it looks good. Had more projects with rich solar panels, they arrived very good condition with great packing materials. The solar panel works great, I love to shop with rich solar panels, much more value than the other brands. High recommend!

High quality! So far so good! Appears to be a really high quality product that seems to be working just great. I am using this panel to power a solar powered aeration system that I built for my 1/2 acre pond in an attempt to control algae growth. Been running for a little over a month now and all of the algae in my pond has disappeared completely. This thing works great! I got it at a great price and it arrived right on time and in perfect condition. I will definitely be returning to this seller for future solar panel purchases.

Well built, light weight, and easy to handle Well built, light weight, and easy to handle. Bought the panel to dip my toes into solar by charging my lithium battery pack that has a solar adapter port. Works great takes a few hours to charge the thing back up. Considering building a more complex system to take some of my big appliances off the grid.
