Add another Redarc solar panel to your solar system to increase your charging power and extend your off-grid campout. Multiple-panel solar arrays are most efficient when you use panels with the same wattage, so we recommend adding this to a system with other 180-watt panels. When panels of different wattages are combined, the panel with the larger rating will have its performance reduced.

Be mindful of the amperage and wattage limitations of your solar charge controller, as exceeding those limits may cause the solar array to not function.

Wiring panels together

Redarc offers multiple options for connecting multiple panels. It's important to understand what effect they will have. If you are unsure of what would work best for you, you should consult an electrician or dealer for professional advice and installation.

Three options for wiring Redarc solar panels together

Redarc offers Anderson connectors to wire panels in series (RED53VR) or parallel (RED59VR). By wiring your panels in series, you will increase the total panel voltage output. By wiring your panels in parallel, you increase the total amperage. In both cases, you get increased battery charging power going to your solar charge controller. If you increase your total voltage or amperage beyond what your charge controller can handle, it will not function properly. In solar arrays of 4 or 6 panels, you can wire half in series and half in parallel, so neither the volts nor amps exceed your controller's limitations. By being mindful of these options, it can save you the pain of having to buy a more expensive solar charge controller that can handle the increased input.

Redarc also offers MC4 style connectors for wiring panels in parallel (RED78VR). Since the connectors on the panel itself use MC4 connections, this eliminates the need for an MC4 to Anderson adapter and will make for a cleaner install.

Mount for joining 2 Redarc solar panels

For installing panels on the roof of your RV, also remember to get some Redarc Solar Panel corner mounts (RED79VR) and side mounts (RED89VR). The side mounts are especially great for multi-panel arrays, as they hold two panels together at their corners, conserving space on your roof while holding panels securely.

Video Transcript for Review of Redarc RV Solar Panels - Roof Mounted Solar Kit - RED46VR

Hello everybody, this is Jeff at Today we take a look at this REDARC 180W Monocrystalline Solar Panel. Now this is 180 watt solar panel that'll use the sunlight to the charge your batteries, and this panel is designed for a fixed mount installation, typically on the roof area of RVs, motor homes, as well as some camper trailers and some four by four vehicle applications. This panel is designed to work with the REDARC Solar Charge Controllers. Also works with the REDARC Dual Input BCDC chargers, and works with the REDARC Manager 30 Battery Management System. All three of those items, we do sell separately on our website.

Now this solar panel is a monocrystalline panel, has the highest efficiency rate, typically in the 15 to 20 percent range. And this high efficiency rate means that they produce more power per square foot, and are therefore very space efficient. Does use a nice tempered glass coating, has a nice anodized aluminum frame to withstand harsh road and weather conditions. And the mounting brackets to install this are sold separately, we do list them on the product page. I did want to zoom in and show you the very back.

In the back here, they have the junction box right here, and then you have your two cables coming out. Has the MC4 connectors on it, the length of these cables is about 35 inches. And these MC4 connectors provide a nice quick and easy setup, they'll plug into your solar controller. And these parts are manufactured to CD standards. Now, a few dimensions on this, the length from this end to this end is 58 and one sixteenths inches long.

The width from the top to the very bottom here is 26 and three eighths inches wide, and the depth of this panel is only about one and three eighths inches. Total weight on it is about 23 and a half pounds. You spectrum this, the rated peak powers is 180 Watts, maximum power current is nine amps, maximum power voltage, 20 volts, and the operating temperature of this panel is negative 40 degrees Fahrenheit up to a 185 degrees Fahrenheit. Now this is the hundred and 80 watt version. We do also selling 50 watt panel, an 80 watt panel, 120 watt, and then even a larger 200 watt panel and all four of those panels we also sell separately on our website.

But that should do it for the review on this REDARC, 180 watt monocrystalline solar panel..

Paul is awesome


If you do a lot of remote camping, this works really well. Combined with a BCDC charger, this is the ultimate batery charging system.
