Exactly follows the specs as I understood them. I’ve had mine sitting on my roof, pushing electrons through a cheapo charge controller into and past a 12v car battery. It’s been there for about six months in all weather, and I haven’t had any problems.

I live off grid and love theses panels. Have six so far and still adding on. They’re very durable- I have one set up on my camper and it’s blown over several times. The ones on my roof have been through multiple Montana hail storms without a mark on them.

This has been working great! I bought it because after about a day my battery in my travel trailer would be drained. We use led lights and the water pump off of the battery. With just a few hours of sunlight the battery is completely topped off and ready for service. I bought a second battery thinking I’d need it, but it was unnecessary. It was easy to install on top of my new trailer with basic instructions found on YouTube. We’ve gone through heavy rain with no problems.

It has 2 diodes inside the junction box and the lid has an orange silicone seal.
I use my panel to charge LiPo batteries at 5A

This product is designed and built to be outside in the weather. The frame and front glass do not flex, they are solid and are good support for the pv cells they contain.
The 100 Watts is calculated by multiplying the output voltage by the output current. Both rated voltage and rated current were produced for me on a sunny day at 37 degrees N latitude.
If you are using this to charge 12 V batteries as I am then you will not get 100 Watts out of the panel because the rated voltage needed to get the 100 Watts is higher than the ~14 V used to charge the batteries. You will get the rated Amperage however it will be at the ~14 V that is being used to charge the 12 V batteries.
To get the full 100 Watts you would have to go to a 24, 48 V or higher system. If you are on those type of systems then you know this already. If you are starting with a 12 V system then beware and don’t expect a full 100 Watt output.
Nominal output Voltage is 17.9 Vdc, Nominal output Amps is 5.6 Adc — 17.9 x 5.6 ~ 100 Watts
Charging Voltage is ~14 Vdc -> 14 x 5.6 ~ 78 Watts

Love these solar panels. I’ve installed 4 panels now and it keeps my 4 – 6 volt RV batteries charged and maintain me fully when dry camping with a 3000 inverter system. I even have a residential refrigerator.

While this panel does produce what it’s rated for, I feel that this brand does not compare well against the Renogy panels I got two weeks ago. The frame dimensions are smaller giving less depth for mounting hardware. The wires are 12 gauge aluminum rather than 10 gauge copper. Also I had to replace an mc4 connector immediately because it had plastic flash in the tip and the barrel broke on the male connector on the first hook up. Although I did save $20 per panel compared to the Renogy’s, I would not purchase this brand again.

I bought an RV with a solar panel, but no charge controller. Bought a charge controller, not the problem, the old panel was DOA. Bought this one for an off-grid camping trip, and was up and running within minutes. Very solid construction, and easy to wire into the system. It quickly and easily topped off my batteries, and it will be a lifesaver on these dry camps. As good as it works, I am tempted to buy a second to parallel, double my charge rate.
