Renogy Solar Panel 50 Watt 12 Volt, High-Efficiency 50W Solar Panel Monocrystalline PV Module Power Charger for RV Marine Rooftop Farm Battery and Other Off-Grid Applications

This is a great quality solar panel. I have had a few other small trickle panels and a cheap flexible plastic one (total waste of money) and I am really impressed with the power and quality of this panel. It is really too strong for a trickle panel, but i find I can put it in the shade and it works fine with less power and it will totally charge up a "dead" car battery in no time (paired with a cheap charge controller, made mobile safe by hot glue gunning wiring points). I bought a panel this strong because I got a great sale price on it. Very worth it. Small enough to be portable and easily moveable and will fit on my dash even and large enough to really kick ass, charge up a lead acid battery and all my 5 volt usb lights and devices. Great for camping. My only problem with this panel on the onset was that it came with Renology MC4 connectors attached and I had trouble deciding whether to buy more of those or rip off the MC4 connector and just convert to 12 volt automotive water proof connector I already had on hand. For my uses, I was better off without the MC4 (a waterproof rating not size rating) I decided, and I finally pried them off and converted to the 12 volt auto connector, but the psychological block really impacted my project.

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!

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.

Brand and quality, works better that expected,

The panels looked well built and sturdy. Shipping, in two boxes, had damaged the frames of one panel in each of two boxes. No replacement option was offered, so I returned both boxes. I believe I will buy these in individual purchases, so each can be replaced separately.

I was shocked that it was pulling in 40w in direct sun which is extremely efficient, it’s essentially able to fill my 256 Wh Anker battery to almost full daily.

50 Watt Solar panel is an Excellent item for a chicken coop fan and it’s very lightweight to mount anywhere where needed. Compact panel also great for any type of emergencies. Great for charging 300-500 watt portable generators when camping out. Good for the money

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.
