ECO-WORTHY 2pcs 100 Watt Solar Panels Monocrystalline Solar Panel for 12V/24V Battery RV Marine Boat and Other Off-Grid Applications, 2-Pack 100W

As the price has been plummeting on these i’ve been buying them pretty much continuously as I can afford them. I find that in real world application in Southern Indiana on a clear winter day at a perpendicular orientation to the sun. I’m getting about 95 W. This is about what I expect out of solar panels. They are so cheap now that I don’t even bother and making sure that they have optimal tracking access to the sun. I have some of them oriented to morning sun some of them oriented to evening, sun, and some of them are used as border walls for the patio. That way I can make use of all of my available space. I’ve strategically wired them so that the controllers get input from panels as the sun moves so as to maximize my controller inputs from the panels, i.e. one one panel set is starting to lose sun, the next panel set is starting to gain sun. That way, the controllers are having the most made out of their time. Because they are getting so cheap, whenever I find a coupon or promo offer, I just buy it. I have a bunch stacked away so that if I have any damaged, I can just drop them in and replace them. So far in almost 40 years of being off grid, I’ve only ever had two panels fail. And in about four years of using these, none have failed and none have been damaged. I’ve only ever had one arrived damaged, and it was quickly replaced with no questions asked.

I have 6 of these panels wired 3s2p going to a Bouge RV 40amp MPPT controller charging two 12v 100ah Lifepo4 batteries going on 5 years now with absolutely no issues. I use them in an off grid manner to power security lights, wifi, and keep tool batteries charged. Just ordered a 4 pack today and a 48v golf cart battery to step my game up. Highly recommend these as they are easy to expand and configure.

I waited 8 months to review these panels so I could comment on the longer term performance. First, they arrived promptly and were well packaged. They are light and easy to handle when installing. They have been through Fall, Winter, and Summer and have withstood storms with high winds. I do not have a south facing roof so I installed 2 on the east facing roof and 2 on the west facing roof. On a sunny summer day, they will charge my Bluetti at 250W. That is excellent considering they are not efficiently facing the sun. They are a great value!

Bought 4 of these. Setup 2 series/parallel. Peak sun I get 400w. Spectacular.

Great for the price! Been using it for a couple of years now with no issues. However they are not 100 watts. The highest I’ve seen is about 70 to 80 max.

I don't give reviews right away and I purchased these a while ago so hopefully the quality is still there. Do what they're supposed to.

Used these to provide enough power for lights and battery charging for power tools love absolutely plant to by more.

These are great 100 Watt Solar panels. They are lightweight (12.5 lb each) and has a sturdy aluminum frame with pre-drilled mounting holes. I currently have these mounted on my patio cover and they are producing 3-4 amps per panel. You cannot beat the price and quality. I got these to replace an old set of 80 Watt Solar panel from the 2010's. These are lighter and smaller than the 80 Watts! The solar panels arrived quickly and were packed well with Styrofoam. I inspected the panels carefully (before the delivery guy left) and did not see any damaged glass or wiring. The junction and solar connectors are IP65 rated (weatherproof). I'm very please with these panels and will purchase another set to expand on my off-the-grid battery backup system in the near future.
