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 12 now and working as expected 4 more soon Real world results you don’t need the most expensive ones out there . Great quality

Sturdy construction, very well made. Good stable output, plenty of power.

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.

Solid Panels, Lightweight and Efficient—But Bifacial Needs More Clearance I’m currently running four Renogy 250W bifacial panels (shown in my photo), and they perform impressively—on clear days around noon, I can get over 1000W. I chose these panels specifically because they’re lightweight and easy to carry up a ladder, which made installation safer and more manageable. My other option was the 320W Renogy panel, but it had fewer bus bars, which I felt could affect efficiency and durability over time. Charging my Delta Pro (3600W capacity) from 10% takes about 5 hours on sunny days (9am–2pm). On cloudy days, it can stretch to 8–9 hours. I plan to install two more 250W panels soon, and I’ll likely paint the mounting surface white to boost reflectivity. Eventually, I’ll add more brackets to increase clearance to around 3 inches. I’ll be stacking them—not sure it’s designed for that, but I’ll McGyver it. If that doesn’t work, I might just leave it alone. For wiring, I bought 100 feet of 10-gauge solar wire for about $150 (should’ve gone with 50 feet instead). It plugs into the panels easily, and the other end uses an XT60i connector to plug into the Delta Pro. I did make a few pilot screw mistakes—missed the roof 2x4 twice—but patched it up with Henry silicone putty. Hoping that holds and doesn’t leak. The brackets I initially bought didn’t support linking six panels together, so I had to order extra T-shaped brackets to bridge between panels. They save about 1.5 inches between panels, which helps when space is tight. Shipping: I ordered 4 panels in one day during a sale (that was the max allowed), then 2 more a few days later. All 6 arrived together—expected delivery was 6 weeks, but they showed up in just 2. Unfortunately, 4 of the panel frames were bent at the back, and one panel had a banged-up middle section that warped the entire panel. I even considered stepping on the center to straighten it out. Luckily, they all work and the front sides were undamaged. It feels like I may have received cosmetically rejected or slightly damaged stock. Looking ahead, I’m considering building a 48V LiFePO₄ battery with 16 cells and a 200A BMS, since shipping batteries to Hawaii isn’t an option. Overall, great performance and a safer install thanks to the lighter weight. Just keep in mind: bifacial panels need proper clearance and reflectivity to deliver their full potential—and be ready to improvise a little if you're DIYing like me. 9/2/25. Update from 4 panels to 6 panels. Now even faster charge.

Renogy makes great panels, I have 6 of them in total. All but this one have come in great condition. I thought from looking at the box that it was going to be smashed, but it wasn’t. There was tape everywhere on the box. All the Renogy panels I received before had no tape, and this one had lots. There was big dent on the top rail of the aluminum and one corner I had to play with to get it to look better, corner not fit well because of dent next to it. I would have sent it back just because of that but the 175w hard panels are hard to find and are expensive. I should have just got the 200w panels. There seems to be lots of them around and cheaper. I still need one more 175w panel to complete my string. I am just thinking of getting a 200w panel. It’s a little bigger but don’t want to pay extra for smaller panel, and also wait till they have any in stock. I test the panel and it seems to still be working good. Haven’t had much sun lately, to test real output of it. I guess we live and learn.

​Habe das Panel für meinen Camper gekauft und es ist seitdem dauerhaft im Einsatz. Bisher absolut keine Probleme! Durch das schlanke Design passt es perfekt auf das Dach und die Energieausbeute ist hervorragend. Kann ich jedem Van-Besitzer nur empfehlen.
