HQRP 85 Watt Solar Panel 85W Power (Size of 80 Watt / 80W) 12V Monocrystalline PV Module plus HQRP

I bought two of these panels for my boat.

Goods showed up, was installed and works as per the description.

There could have been more documentation included but I knew what I was doing so it was not a big problem.

I measured the outputs and found them to be very close to the specs (17volt/5amp).

Recieved the solar panel as a gift. I had it mounted on my 2006 981 Lance Max Camper with dual batteries. This panel keeps my batteries in top condition and fully charged by evening. Great product. Plan on buying another one to hook up in series on my camper for extended dry camping.

Made custom mounting hardware for this panel. It was easy to install and I saw a peak amp output of 4.8 Email me of a picture!

I've copied my review of this panel and a charge controller combo (HQRP Solar Power Controller 10Amp 150W with Digital LED Display) since my review contains details for both products and might be useful to others.

I purchased a relatively large Jayco camping trailer (Pop-up) this year and wanted to be able to dry camp for a week at a time and not need to haul along a generator or be overly worried about conserving electricity. After doing the math I upgraded the stock group 24 battery to a group 29 and found this panel/charge controller combination for a bit of a discount over buying each separately. I did a few "dry-runs" at home by discharging my battery 20-40% and bringing it back up with this panel and controller and my battery was left with the same charge that my Schumacher SC-600A charger left it at so the controller's charging logic seemed sound. Using this in the field I'm happy to have plenty of power to the point that the charge controller is usually indicating a full battery by 9:30-10:00 each morning after a night with a few hours of running about 20 watts of dome/patio lights, the water pump as necessary, two small fans overnight and the furnace induction and blower fans as needed. The system has been reliable and performance has been great so far. While I haven't hooked up a meter to verify output, my back-of-the-envelope calculation based on draining up to 40% of the rated capacity of my battery and then charging it with this panel/charge controller combination it seems to be working as advertised.

I used some 10AWG outdoor rated wire and connectors leftover from my home PV installation I completed about 3 years ago which allows me to place the panel up to 20' from the battery to get it clear of trees or other shade that we like to place our trailer beneath. Worse case I can pull the battery off and move both battery and panel/charge controller to a more favorable charging location during the day and return it to the trailer once charging completes. I crimped some ring terminals on the wires going from the charge controller to the battery for easy installation/removal keeping these wires about 2' long to reduce losses from the charge controller to the battery and keep the charge controller sheltered by the bunk that slides out over the front of the trailer. Being 85 watts this panel isn't small so spend the time to look at the dimensions and make sure it will fit wherever you plan to store and use it. Mine stows beneath the dining table with about 6" to spare.

I did discover that the panel is reasonably tough as my wife mentioned to me one evening that she caught our friends' kid standing on it behind our trailer. Yes, actually STANDING on the glass portion of the panel while it was lying behind our trailer. This panel is build in the same manner as my 200 watt panels on my roof with an aluminum frame and PV cells glued to the back side of a panel of glass. Now I know this panel can support at least 40 pounds of kid without failing. I was prompted to put together a small "A-frame" stand made with leftover aluminum rail and brackets from my home install so now I can do a better job of optimizing the tilt of my panel and hopefully avoid subjecting the panel to a load-bearing stress test!

I have 4 of these panels, and all four are running flawlessly.

Mine are mounted to the top of my converted cargo trailer, and power a bank of 8 125 AH Deep cycle batteries.

The environment that these panels are in is subject to a lot of wind, vibration, and of course exposure to the elements.

They have stood up well, and only need cleaning every couple of months or so.

I have noticed that the power output was slightly higher then the specs say at first, but they settle down

after a month or two.

These panels arrived fast, and where fairly well packed. I noticed only one of the four had a minor scuff, where the edge of the box had been dented in.

It is true that these are not the most efficient, nor the cheapest panels one can buy, but you don't have to buy a pallet of them,

they are perfect for 12VDC systems, and are easy to hook up.

The frames of these panels have plenty of extra room to mount your own custom hardware to, or if need be, mounted together to form one larger panel.

Great panel, fast shipping, super easy instal, and best of all

they just plain work!
