HQST 100W 12V Monocrystalline Solar Panel with Solar Connectors, High Efficiency Module PV Power for Battery Charging Boat, Caravan, RV and Any Other Off Grid Applications

Great panel at a great price I bought 7 total.

5/3/2025 - Just installed and everything test good. Great power output. I can't give specifics because I'm running this one in parallel with a Grape Solar 100W panel that is 4 years old and I got combined output from the two at least 150W before clouds arrived. I mounted these onto my roof with Unistrut rails and these hold-down clamps (https://www.amazon.com/dp/B0DQL39VTV). Very impressed so far. If mounting on a camper/van, I would not mount directly through the thin aluminum frame holes. Use more robust solar panel clamps like above and ensure those clamps are near the front of the panel to reduce potential for wind to lift the front and break the panel. For normal use, the frame is certainly strong enough.

So far, a solid panel, especially for the price! Testing right out of the box with my multimeter in direct afternoon sunlight, I’m getting 22.1v and 6.03A, for 121.2W. The cables are shorter than I would have liked, but they are made with nice sturdy wires, and solid connections. They are nice and light, which is great for setup, and using them in the RV. 9bb, as described, so far it works works very well. I will update once I get some measurements in low light conditions, as is common up here in the north. If the PERC technology outperforms my standard panels on the cloudy days, I will update you 5 stars!

These seem to be good quality panels. They were packaged well and arrived with no damage. They work well for my little solar setup.

Purchased for home backup to charge power stations and a couple of lithium iron phosphate 100 ah batteries. Tested in good sunlight and got around 90 watts. The price was good so I bought a second one using the “buy again” button. Second panel arrived and it also tested good output. Only issue was it was a different size. It would have been nice to be notified by the seller. Fortunately I place them on a rack of sorts so it’s not a big deal. Guess I should have bought the 2 pack.

I went by reviews on Amazon and by reviews on YouTube, this solar panel exceeded my expectations. It has actually produced over the 100 watts, giving me up to 103 watts on a bright, clear day with the panel at the perfect angle. The build quality is solid and well made. I can't complain for the price, I look to see this with my Allpowers R600B V2 reduce my electric bill and be handy during storm season and as a portable power supply for many projects.

Performs as advertised, high quality and great price.

For the $50 cost, it provides a great value. Highest output I have measured is 96 watts. Panel seems to be more susceptible to higher heat (above 90 F) than the Renogy 100 watt panels I use. Good buy.
