  • Not sure if these panels are good quality Not sure if these panels are good quality
Size: 10Pcs
After installing 20 panels on roof over one month, three panels burned inside but they replaced all pretty quickly. I’ve got 3 more panels burned yesterday. Look like these are poor quality panels

  • Great Output Even in Cold, Low-UV Weather
Size: 2PCS
I held off on reviewing these Renogy panels because I wanted to see how they’d do once it got really cold here (and our UV index drops a lot). Turns out they still perform great. Even on those lower-sun days, they’ve been producing steady power and I haven’t seen any weird drop-offs. Install was straightforward and everything hooked right into my existing solar setup without any drama - connections lined up and it all just worked. If you’re worried about winter performance, these have been solid for me so far and I highly recommend them. ... show more

  • Solid, Heavy-Duty Panels at a Fair Price
Size: 2PCS
These panels are big, heavy, and feel very well-built. It looks like Renogy addressed some issues seen in older models, and the overall quality is impressive. For a pair, the price is actually quite good compared to similar panels in this wattage range. I’m still in the testing phase, but my long-term plan is to run my entire desk setup — PC, printers, monitors, speakers, and more — from a battery bank charged by these. So far, everything looks promising. Power output performance, in ideal conditions matches listed specs on both mine. You'll definitely need to bring your own mounting solution, but that's not that unusual with panels of this caliber. ... show more
