Renogy Solar Panel 100 Watt 12 Volt with Mounting Z Brackets High-Efficiency Monocrystalline PV Module Power Charger for RV Marine Rooftop Farm Battery and Other Off-Grid Applications

Do your homework, and limit your expectations. There are many considerations in solar panel technology other than their advertised wattage. Lots of things factor into how many watts your panel can harvest over any given time. Expect less than half the watts advertised for starters, and work on efficiency over time. Once you understand that solar panels must be angled at varying times and degrees, rather than permanently fixed to maximize efficiency, you'll be well on your way. Yes, you can permanently mount the panel in a horizontal position, but depending on the surface and angle of the sun at any given time, this will affect the amount of watts you can harvest. Another big consideration in panels is the amount of landscape they require for their installation, their prospective location, and surface, if any. Some are larger than others and heavier too. The flexible and folding ones have their drawbacks as well. Consider where you plan to put them and how you plan to use them before deciding what to buy. After a lot, a lot, a lot, of reading and research, hundreds of product reviews, and a determination to return them if they didn't perform, I bought these. I'm glad I did because they didn't disappoint me. I don't get 100 watts out of these panels, but I also don't run the risk of overloading my system. Again, be wary of the maximum wattage stated. You'll never get that out of any panel unless perhaps you're out in space pointed directly at the sun. Finally, it's usually a logistics issue but be aware that these require special handling, so even though they were advertised as Prime in terms of delivery when I bought them, mine took a couple of weeks to arrive. At no time were they advertised as being out of stock, so it's fair to think their size and handling are the reason they take so long to arrive. Others have experienced the same kind of delivery delays, so be advised you may not get them in a hurry and so should plan accordingly if your need is urgent. All-in-all, for the price point, these are a very fair deal, even more so if you happen to catch them on sale, as I did. I'm a satisfied customer even if I had to pay regular price and expect you will be too.

This solar panel was an addition to the roof-top solar on my travel trailer. I used the previous version of this panel on my boat a few years back, and had no problems for 3 or 4 years, so went with the same brand again. Glad I did. Installed easily with the Z-clips, worked great, and I have now ordered a second one for the trailer to boost my charge rate even further. I have and will buy these panels again.

A really great solar panel. Mine's been going four years straight with no issues. The only issue is customer service sucks so I've heard but I haven't had to use them yet but they do require you to download an app and all that stuff.

I love this solar panel. I installed one and realized that I had room for another one. The second one arrived shattered. I wound up just using the one and this charges my battery faster than the two amp 120V charger that I was using. Really happy with this and might order more for future project.

I like these panels, I'm slowing adding to my solar farm. I use them to charge my Lifepo Batteries and run my Ham Radio station. I have 2 that have served me well for a few years now and are still going strong. Haven't noticed and degradation in output yet. They put out a decent wattage even in the shade and cloudy days. Can't go wrong with a Renogy panel.
