Review by Terence Iverson for HQRP 12W (Size of 10 Watt / 10W) Mono-crystalline Solar Panel 12 Watt 12 Volt in Anodized Aluminum Frame plus HQRP Mousepad
Rating:
All of the materials used to build the panel are very good, The aluminum frame is solid, The glass is real glass and is the correct type of glass for a solar panel. The solar cells are very good quality. The only problem that there might be is that I can’t tell if the panel has a built in Diode or not. Not having a diode should not make any difference unless you are hooking the panel up without a charge controller. Any charge controller you can get will have a diode in it so no worries.
Shipping – One of the pictures shows the panel with styrofoam at each corner in a box, My panel came in this box, plus that box was inside another one, I thought having the panel in two boxes was really good because it offers better protection for the glass in the panel. I was happy to see this when it arrived as our mail here gets tossed around quite a bit.
What it comes down to is that you get exactly what is in the picture.
The only other bad thing is the free bonus mouse pad, It is really useless unless you have a round computer screen, which I have yet to see.
Update 1/22/2010 – I was wrong about the panel not having a built in Diode, I took the cover off the back and there is a diode installed for sure.

Exactly what is advertised. I hooked 2 of these in parrarel through a Brunton controller to a 275 watt lawn tractor battery and a 400 watt inverter to run my outside lighting at night. Works like a charm.

Review by Randy L. Cross for HQRP 12W (Size of 10 Watt / 10W) Mono-crystalline Solar Panel 12 Watt 12 Volt in Anodized Aluminum Frame plus HQRP Mousepad
Rating:
I purchased this product because of the good reviews. I am very pleased with its performance. Living in Washington State without much sun, it does very well. I use it as a trickle charger for battery back-up to my Ham Radios. When the sun is bright and directly on the panel is when the panel works the best of course. It is well made and easy to install or to mount. I plan to purchase a larger panel to charge faster on cloudy days. If you want a panel to maintain a battery or two this works fine.

Review by D. WOLF for HQRP 12W (Size of 10 Watt / 10W) Mono-crystalline Solar Panel 12 Watt 12 Volt in Anodized Aluminum Frame plus HQRP Mousepad
Rating:
I am very pleased with the performance of this small panel. I paired it with a Brunton Solar Charger to maintain two 60 Ah 12 volt batteries and it keeps them charged up.
I have a 600 Watt Inverter I use to power lights, a small pump and other devices at our -off the grid- location. This panel keeps the batteries at a charged level.
Obviously this panel is too small to rapidly charge anything, but it is amazing how much it can deliver even in low light situations. Well constructed, worth every cent.
Nice shipping container as well.
