Renogy Solar Panel 100 Watt 12 Volt, High-Efficiency Monocrystalline PV Module Power Charger for RV Marine Rooftop Farm Battery and Other Off-Grid Applications, RNG-100D-SS, Single 100W

Amazing panel, works great i get anywhere from 70 to 90 watts with it laying basically flat.

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

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.

These panels are awesome. They out put as advertised and are very easy to work with. they can deal with up to 85 MPH highway speed for serval hundred miles. they tanked a light hail storm with no issues. These are 100% good to go. they are nice and rigid and will fit in a roof rack using 80/20 aluminum extrusions. If you need wattage on your van build this is what you want to go with. I run a 12v fridge, work labtop, gaming labtop, 4kw inverter, lights, fan, a ton of stuff. I can run a 5000 BTU AC unit off nothing but the noon sun on a clear summer day. These will keep the lights on.

The panels (5-stars) work well...when... ...they actually get around to shipping them to you. I've eeduced 2-stars because of the aggravation with shipping. The vendor/Amazon will claim that the item has shipped, for weeks, but the truth is revealed as UPS (the record of truth) always denies receiving the the item(s). You may get the item in 3 weeks. This situation is worse if the panels are on sale (10% off, etc) - even longer transit times. You may get the item in a month or more. So the panels are very good but shipping games are terrible. Also, the vendor hasn't figured out how to use packing tape (say 3-4 8" pieces), so that their overall good packaging won't pop open - with damaged items eventually arriving. To be fair, they will provide you with a UPS label to send them back. This is good. Those responsible for these Renogy fulfillment blunders should be replaced, yielding more profit for Renogy and more satisfied customers that spread the word. I am ready to buy 6-7 more of these 200W panels, but...what further headaches will I be dealing with? It is amazing how some of these companies manage to make a profit. This isn't rocket science! One smart person put in charge of fulfilling orders, and like magic, business would improve a lot. I will update this review when I attempt this drawn-out journey again. Update 10/4/24: This last panel ordered arrived quickly and in a nice new sturdy box. See what happens when the smart people get involved. Adding one more point!

Llegó muy rápido, sin daños, funcionan a la perfección, Perfecto para casas de campo.

12volt solar set up

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.

Excellent solar panels, no issues and I would recommend them. I have found. Renogy very easy to deal with, good customer service.

Quality made panel, not too heavy, package arrived without damage. Fast shipping. Affordable price . Recommend it.
