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

I like these panels. They are fairly cheap for their output. I'm getting a little over half of their rated output for at least 6 hours per day. That's good for where I live. I do find that they need to be perfectly perpendicular to the sun for maximum output. Even 15 or 20 degrees off can reduce the output by 1/4. If you really want the most out of this type you need to use a sun pointing system or if you are running them fixed, arrange them in very small groups electrically.

Working well so far. I have it hooked up to an mppt controller, then top a regular car battery, and. 8 jule energizer that runs my electric net fencing for my sheep. Easily maintains 13-14v .8-3.5a roughly.

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!

I bought the 50 watt panel, and it immediately started producing 50 watts and sometimes even over 50 ... like 56 Watts. Very pleased!! I'm thinking about ordering another one.

High quality product at a reasonable price. I now have three of these units powering an outdoor camera and a fountain pump. With that said I have never gotten more then 20 watts out of any single unit on a bright day with the sun overhead. My oldest panel is over 2 yrs old and still functioning as good as the first day it was installed.

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.

Renergy is always great quality with very fast shipping.

These are built well with good connectors. They do work.I have a set of 3 these panels mounted on a white roof spaced about a foot apart with brackets to hold them up on an angle, and I find their power generating capacity is nicely spread out through the day because of the light reflecting up onto the backs when the sun is not perpendicular to the panel face. On a sunny day I see power building from 8am, with full power being reached at 9am and running all the way to about 4pm, then trailing off until 6pm. They say a rule of thumb is to expect 5 hours of solar power, and these seem to stretch that about an hour more on each side - a feature I very much like.In February in Florida I see a consistent practical power output of about 200W per panel. The advertised 250W is a bit optimistic; perhaps I'll get more on the best day with the clearest haze-free sky with the sun straight up and the air cool. Realistically, expect 20V at 10A and you won't be disappointed. I see about 1/5 to 1/3 power on an overcast day, e.g. 2 to 3 amps. These advertise 22.35V VoC but I found them to float to a smidge higher than that, to about 23V.
