Renogy 50 Watt 12 Volt Monocrystalline Solar Panel (Compact Design)

5/29/23 Ok, so, I got 2 of these besides the one I bought initially from February of 2017. And they are great, or, at least one of them is because I had to get a pair of MC4 solar panel connectors because these dont come with them from the factory, which is one thing I didnt like. The idea that they didnt come with a MC4 connector (for those wondering what a MC4 connector is, you can easily find what they look like online), yeah, thats great if your only using these with a charge controller where you only need to jam the wires into the bottom of it. Which, the idea of the lack of the connectors themselves is a problem, especially if you either dont have the tools necessary or are not mechanically inclined/gifted like some are or dont know what your doing.

I used this to trickle charge my Bluetti, and it produced some respectable wattage from the panels.

Ive purchased 8 of these. Connected to a HQST 40A MPPT controller, I average around 550 watt hours per panel per day (exceeding advertised 500 watt hours per day) or around 4.4kwhr for 8 panels a day with a mid day peak of 690-700ish watts. This is with some unfortunate shading in the morning but I do live in a region pretty ideal for solar. Only downside is that I dont get the 100+ watts some people are claiming. I peak around 85 watts per panel for maybe an hour a day. These have MC4 connectors which are fairly universal and work with most modern lifepo4 battery bank or solar generators. These work as youd expect, if you need a lot of power youll need to buy a lot of these. A fridge will use 1-2 kwhrs a day, at 550 watt hours each youll need at least four of them to keep a fridge powered indefinitely. That said, its nice to not have to worry about extended power outages. I can generate enough power to power a 400 watt 5000 btu window air conditioner for 10+ hours a day and keep a large battery bank fully charged for emergency use. That said, there are some cheaper 100 watt panels on amazon from HQST and other brands. I plan on giving those a try.

As soon as I received the panels 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 dont work long term but right now I couldnt be happier with the purchase. Edit: Its been a few months now using these panels fully off grid. And I couldnt be happier. Yes I could have spent a lot more money and had fewer panels by buying 300+ watt panels but space wasnt 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 isnt 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 couldnt 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 wont 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 Id add another 5 if I could. The panel that produced 22 volts was made wrong. One of the cells isnt connected and what looks like the solder strip is laying across the neighboring cell face. Still cant complain I purchased 12V panels.

I bought this panel to charge a DIY battery box. You do need to buy a solar charge controller in order to properly utilize it. The panel works as intended, able to charge my 17ah battery fully in about 4 hours.

I purchased four of these solar panels for my Renogy Lycan 5000 to run a portable AC unit. I didnt calculate the Watt Hours and amperage properly. Ended up ordering another four 200 Watt solar panels, even before order another four, these panels work fantastic! I highly recommend purchasing them along with a 4 four solar panel holder, if you order more than two solar panels.

These are compact and well made. Under ideal conditions they can produce over 100w each. I attached a shot of output using four. Excellent!

Plug-and-play SIMPLICITY! REM: take caution to not exceed your Solar Charge Controller’s MAXIMUM input voltage. This is the solar panels open circuit No load DC voltage (roughly 25vdc Voc …. Voltage Open Circuit) x however how many solar panels you have in *series.* Why do we figure Voltage Open Circuit.? When the battery has been satisfied and No longer drawing any charge-current; the charge controller is No longer loading the solar panels and therefore, the charge controller sees the FULL OPEN CIRCUIT VOLTAGE across its input.

I bought a 200 watt panel a month ago and there were no scratches, dings etc. It came nicely packed and everything was in tact. That impression made me buy a 2nd one - this one. I havent hooked it up yet cuz Im still trying to figure out how many watts of a solar system I want to build. But I did buy a 1000 watt portable power station that Im going to use this with. I guess Im willing to pay more for a good product that comes with everything in tact. Renogy is a reputable company from what Ive read on reviews and since both of these panels came without issues, Ill keep buying panels one by one. Just so my system matches and I dont have a bunch of random looking panels next to each other.

These solar panels rock! I have two in series to power my station which needs 30-45 open volts to charge. And with these two 100w panels, Im reading 150w of charging during peak sun hours!! They seem well-made and I have no complaints
