High-Efficiency, Monocrystalline Solar Panel

solar cells

The silicon cells are set between a cushioned backing material and tempered solar glass to withstand the elements. The glass has low-iron content to provide exceptional transparency, which ensures maximum sunlight collection. The panel is framed with anodized marine-grade aluminum to resist rust and corrosion. And in optimal sunlight conditions, the panel produces 100 watts per hour.

Easy Connection to Go Power Solar Charging Systems

mc4 connectors

This kit is compatible with several Go Power Solar Charging Systems (sold separately). However, the total amount of amps generated by the panels cannot exceed your solar controller's maximum amperage. The solar panel installs anywhere on your RV roof with included mounting feet and hardware. To maximize sunlight collection, it is important to install the panel where it avoids shadows cast by objects, like an air conditioner or vent. The panel is wired in parallel to another panel using MC4 branch connectors.

Video Transcript for Review of Go Power RV Solar Panels - Add on Panel - 34272634

Hi there. I'm Michael with etrailer.com, today we're going to take a quick look at the Go Power! expansion kit. This is a 100 watt solar panel that's going to connect to your existing Go Power! solar charging system to increase your system's power output so you can do more while you're boon docking and stay off the grid longer. This is going to work with several different kinds of Go Power! solar kits for the full list. You can see the screen there, on the left side you've got the name of the kit and their wattage, on the right side you've got the etrailer item number. If you want to look them up on our website, you can see them there.

But all of those kits are going to be compatible with this, so if you're wanting to add more power to your system, to any of those systems, this is going to be a great option for you.Now the one thing you want to keep in mind when adding a solar panel to your system is the amps that it's going to have. So you never want to put more amps into your system than your converter can handle. So this is going to give you 5.43 amps. So you want to make sure that with your current system you're not going to be exceeding your converters ability to keep up with it. So just keep that in mind before you add another panel to your system.

But just like your original, this is going to convert your sunlight into safe renewable DC power, so that you can charge up your RV's 12 volt or 24 volt battery systems. As I said, it is a 100 watt panel, and keep in mind that is in best case scenarios. So if you are out in the full sunlight during the middle of the day, you should be getting the 100 watts, if it's early morning, in the evening, or if it's cloudy throughout the day, those sorts of things, you're not going to get that full 100 watts, but in the ideal situations, this will generate up to 100 watts of energy for you.It does have the monocrystalline solar cells, which there are several different kinds of solar cells for your solar panels, that is the best. So it's going to make it very easy to get your power to your batteries, it's going to collect a lot of that sunlight. It's also made of a lightweight, yet durable material, so we have our weatherproof and impact resistant tempered solar glass on top of our panels to make sure that we're going to withstand your hail and debris, those sorts of things.

We also have a Marine grade anodized aluminum frame to help protect against rust and corrosion. This has an IP rating of IP67, so it's going to hold up very well against shock and abrasion, weather elements, those sort of things, it's going to be very heavy duty and long lasting for us.The kit not only includes the single solar panel, but it's also going to include two of these MC4 branch connectors, so we've got a positive and a negative and you can see it's going to allow us to connect our current solar panel plus this new solar panel in each side there and then allow that to run to our batteries. It's also going to include four feet to get this mounted onto our RV's roof and all the hardware that we're going to need to get it installed. When you install this, you do want to make sure that it's close to your current solar panels so that the cable length will all match up and everything, but you also want to be conscious of where you're placing it. You don't want any shadows to fall on it from your air conditioner or anything like that, so you want it to be in a nice open spot near the other solar panels so that you can get all that wiring run.This is going to be a nice addition to any of those kits that we talked about.

As far as our dimensions, it is about 47, just over 47 inches long, 47 and one-sixteenth of an inch long, it's 21 and seven-sixteenths of an inch wide, and only about one and three-eighths of an inch deep. It weighs about a 17.6 pounds, so it's not going to be all that heavy to pick up and move around when you need to get it installed, but keep in mind you are going to be working on your roof, so it can be a little bit more tricky walking around your obstacles in that precarious position, so just be careful with it when you're installing it.It does come with a 25 year limited warranty, so it is very heavy duty, going to be very durable for you. You've got that 25 years of warranty from Go Power!, so if you have any problems you can give them a call and they can help you out with that. Overall, like I said, I think there's going to be a great panel to add to your kit. If you're needing some extra powers that you can stay off the grid longer, I would highly recommend Go Power's panels. I think they've thought it out very well and it's going to be a great addition, great way to keep you powered up while you're out there enjoying nature. So that's going to complete our look the Go Power! expansion kit, again I'm Michael with etrailer.com, thanks for watching.
