Is this right For you? Product Expert Kathleen M says:

Yes, if you:

  • Have a limited budget for solar panels
  • Like keeping things organized - carrying case has a pocket for wires and instructions

No, if you:

  • Want the most efficient panels for the space - polycrystalline works just like mono- but at slightly less efficiency
  • Camp in arid regions with lots of dust or in the mountains where sudden showers are common

Video Transcript for Review of OptiMate RV Solar Panels - Portable 20 Watt Solar Kit - MA89JR

Hi there, I'm Michael with etrailer.com. Today, we're gonna take a quick look at this OptiMate Solar Duo Portable Solar Panel with controller. This is a portable 20 watt polycrystalline solar panel that's gonna use the sunlight to charge your vehicle's 12 volt batteries when you're off the grid. This panel itself is right about 18 inches tall by 14 5/16 of an inch wide, and one inch deep. This will attach to your vehicle's window with the included suction mounts here. These can be mounted in this orientation, so that you can have your panel on the inside of your window or you can put these on the backside, so that you can have your panel on the outside of your vehicle.

So a couple of different benefits and negatives with each of those positions. If this is on the inside of your vehicle, on the inside of your glass, that glass is going to reflect some of the solar energy before it gets to the panel, so it's not gonna be as efficient. If you do have it mounted on the outside of your vehicle, you will have to put it on when you get parked and take it off before you move, these suction mounts aren't designed to hold the panel while the vehicle is in motion. So just a couple different options there for you based on what's more important to you, efficiency or the convenience of having it on the outside of your vehicle, but then, having to take it on and off, that sort of thing. So the design here is that you will have this mounted on your window, then you'll just park with the solar panel in the general direction of the sun, so that it's getting those solar rays to help charge your battery.

This is made of weatherproof material, so it is gonna stand up to the elements if you do have it on the outside of your vehicle. It's got an IP54 rating, so it's gonna do a good job, you're not gonna have to worry about it getting caught out in the rain and that sort of thing. Now, this will connect to your 12 volt batteries, whether they're flooded, AGM, gel, or lithium-iron phosphate from 2 to 240 amp hours. We do have a built-in cable on the back here that's gonna be about 20 inches long. I'm sorry, this cable is about 80 inches long, it's got the SAE connector here, and then we're going to have our controller cable, which is about 40 inches, and then we're gonna have two different ways of connecting to our battery with either the battery clamps here for more temporary installation or a connection, so if you've got a battery that you're just needing to charge up temporarily, you can easily clip these on the positive and negative terminals, and this cable length is about 20 inches.

Or you've got the more permanent ring terminal, so you'll take the nut off your positive and negative posts, get these ring terminals put on, and then put those nuts back on, so this is also about 20 inches long. So overall, you're gonna have just over 11 1/2 feet of length to get connected from your solar panel to your battery. With this ring terminal option, you will be able to mount this somewhere where you can easily plug it in to your controller system. They do have these little slits on the side there, so you can pass a zip tie or something through there, so that you can easily keep these connected and then just plug it in and take it out as needed. Our solar controller itself is kind of the brains of the operation, so as your solar panel is getting the solar energy and converting it to electricity, it's passing it to your solar controller here.

This is going to adjust the solar panel's output for quick, consistent charge. It's going to have an automatic multistage smart charging system that's gonna help extend your battery's life. It will have these LEDs here that provide a display to help you know the charge progress, and it's gonna also help monitor the charge levels throughout the night, so you can see where your battery's at, how full it is, how much power you have left, that sort of thing. This does use a dual method of smart charging system that's gonna help to officially charge the battery in all weather conditions, so it will provide a continuous charge of about 1.67 amps in full sunlight, and then in the lower light, it's gonna provide a pulse charge of about three to five amps, so will do a good job of helping to charge your batteries up no matter what the weather is like. This is capable of saving a dead battery from as low as four volts, so if you've got a really low battery, this will help to charge that back up and get you operational again. So this is a very important component, you wouldn't want your solar panel going directly to your battery, 'cause it could potentially overcharge your battery, charge it too quickly, and that sort of thing, so this is gonna be a very important component to have in line there. Very easy to get plugged in, just uses that same SAE connection, plugs in like that, and then you'll plug in the other end to either your clamps or your ring terminals to get connected to your battery. So all of this will also fit in this heavy-duty nylon carrying case, and so, if you are going to be taking your panel down frequently, you can very easily store it all in here. It's got plenty of room for our panel. and for all of our cables and controller, it's got a little pocket here, zipper opening, so we can tuck all those away, make sure that we have them ready for the next time. Now, obviously, if you have the ring terminals connected to your battery, you'll probably leave those connected like I said, and just have a zip tie there to help support that stay on your battery area. And then we've got two zippers, so we can easily zip this up from both sides like so. And then we've got a carry handle here, so that we can carry those with us. So that's gonna complete our look for today. Again, I'm Michael with etrailer.com, thanks for watching..

See what our Experts say about this OptiMate RV Solar Panels

  • Recommended Battery For For Enclosed Trailer Security/Alarm System
    A lithium battery like the Power Sonic RV Lithium Battery # PS34FR is going to be the best battery type for your alarm system. Lithium batteries handle the cold weather better than AGM or Deep cycle batteries that can freeze. Traditional lead acid batteries can freeze at temperatures below freezing since they use water inside the cells, this will actually lead to the battery becoming damaged internally and no longer working properly. I recommend using a OptiMate Solar Duo Portable Solar...
