Renogy 2PCS Solar Panels 100 Watt 12 Volt, High-Efficiency Monocrystalline PV Module Power Charger for RV Marine Rooftop Farm Battery and Other Off-Grid Applications, 2-Pack 100W

Have 3 of these 100W 12v panels now and they've exceeded my expectations. In full sun on a clear day I can get 95W out of every panel! 89-90 more common but even still that's very efficient. Very happy with these panels in both series and parallel setup. Very well constructed, highly efficient panels. Would recommend them to anyone. Pro-tip: if using a few of these with portable solar generators set them up in series instead of parallel. Most of the solar generators can handle 25-60v but only 10-12 amps of current. Parallel stacks the current 4.91+ 4.91+4.91=14.73amps @12v), series stacks connection stacks the voltage (12v + 12 + 12v = 36v @4.91amps). Hope this helps someone else out.

The combine two panels can reach up to 200 WATTS of power. Both worked well and as expected. You will need to buy the controller, connectors, brackets and wires. Not difficult to install but it took me the better part of the day. Tech support will answer the phone but were no help in figuring out the installation. A bit disappointing. There are a lot of videos on what to buy and installation options. They are new and so far, are working as expected. I would buy again. The first installation went well but the non-drill brackets were permanent and I sold them with the tent. Where permanent is good, it would make repairs impossible. New installation is all bolt together using rails. I attached the brackets to the bottom of the rails using bolts. This kept the panels just below the rail top (some protection) and this would allow for removal in the future if damaged. Added a few pictures. The panels are working well and getting good output.

I bought these panels on a black Friday deal. I own 4 other Renogy panels and have had great success with them. The oldest is 4 years old now and I have not seen any notable deterioration in the charging output. I have an off grid setup for my camper which stays out at our remote property year round. I am using two of these 100 Watt panels wired in series, feeding an Epever MPPT controller and feeding a 100AH Lithium battery. We have some very cold nights in the spring and fall, so the heater may run continuous, but the system recovers great each day with these panels.

As soon as I received the panel's I unboxed everything and set them in the sun to check if they worked. First things I noticed is they are built really well, and they sent me 24 volt panels and I ordered 12 volt so a big plus for me, 96 volts of power from an expected 48 so again a big plus in my favor (After ordering a total of 22 of these they are all producing more than 100W each unfocused and YES they are a good deal). Next I pointed them at the sun and was getting more than rated voltage when in a direct angle to the sun, and I got a reading of 24.5 volts DC on all but 1 which was 22.8 volts DC with them pointing unfocused; in an attempt to imitate the angle they would be in a stationary system on the roof. Of course my opinion may change if they don't work long term but right now I couldn't be happier with the purchase. Edit: It's been a few months now using these panels fully off grid. And I couldn't be happier. Yes I could have spent a lot more money and had fewer panels by buying 300+ watt panels but space wasn't a worry for us money is. We would have spent quite a bit more per watt buying the higher wattage panels. The important thing is each and every one of my Renogy solar panels produces more than the rated wattage under full sun. It isn't a lot but we get over 3200 watts total under full sun with 30 panels now. Which means there is over 200 watts higher than rated wattage total. Thats 2 panels worth. I call them our ghost panels. My opinion of these panels and the company couldn't get better. The PowMr 5000W CC/Inverter we are using can take 450V to the MPPT with a max of 500V 16 amps. Two arrays of 15 panels each at 13 amps is where we are now, thats about 250 V 6.5 amps per array. We are going to add more panels to reach the 450V 16A input potential. Right now we only use battery power under full sun if we use the dryer or microwave oven, everything else is powered between say 8:00 AM to 6:00PM by our panel array which are not focused and is a bit small yet. That includes recharging our battery bank, watching TV, coffee on, lighting and the fridge. If the dryer and AC are on at the same time we may see a small draw on the batteries around 1 or 2 amps when the dryers heating element is powered, which is intermittent. Right now we are fairly balanced. The panels run everything in the house pretty much during daytime including recharging batteries, and the batteries at night; which means the panels are producing all the electricity we use. Adding a few more panels will end using any battery power during a sunny day and adding panels to reach 450V max will probably accomplish that on a cloudy day. And thats the last thing I want to mention. Even though power production does depend on how much light is blocked by clouds or shadows, they do produce power on overcast days. A thin layer of clouds won't appear to make much difference and even on a day with a few rain clouds around we will have power coming from the panels. So my rating is 100% 5 Stars and I'd add another 5 if I could. The panel that produced 22 volts was made wrong. One of the cells isn't connected and what looks like the solder strip is laying across the neighboring cell face. Still can't complain I purchased 12V panels.

These panels are well made and perform as described. Some inefficiencies prevent a full 100 watts but that’s expected.

Strung up 4 of these on an off-grid cabin connected to a 40A Renogy Rover and Inverter Charger. They keep my 200Ah battery charged up no problem. I’ll be expanding to four more in the coming years.

These Solar Panels work perfect dude. I put them on top of my rack on my truck and keep them plugged into a Anker Solix Power Station and they keep it charged 24/7. I used them during winter on a trip across the country and they kept the battery charged even when it was cloudy they still pulled a great amount of power. I can't wait to get some more for a home power solution. Thank you guys for putting in the work for use remote work guys!

Great panels, easy to install, output is very good with high voltage in full sun
