Solar panels use the energy from the sun to convert light into electricity. A solar panel helps in collecting solar energy so that it can be used to fulfill general daily electricity requirements as well as development of advanced technology. It is a great alternative for generating electricity which not only brings down your electricity bill, it also helps in reducing carbon emission by not using electricity produced by fossil fuel. ALEKO solar panels use the most premium components and raw material. ALEKO solar panels use only 'grade a' quality, high purity silicone cells. ALEKO does not incorporate used, rejected, refused or second-hand cells into its solar panels. The aluminum frame is specially produced for ALEKO solar panels and is designed to provide a perfect balance of technology, style and function.

Well good luck getting a hold of someone from HQRP to address the issue. I have been trying to get a return or refund for over 5 weeks now. You can only leave a message on their voice mail and request help. I had one return call after calling them and politely leaving them messages asking for assistance and they left me a voice mail but they have never followed up. I tried to request a return on their website but there site form was broken. When I did get the form to go through (the next day) I got no response.
There are similar priced panels from other manufactures on Amazon. I would suggest those instead of an HQRP branded panel.
HQRP is showing how poor customer service can be. I am surprised Amazon does business with them.
- 17V output voltage will do a good job of charging 12V lead-acid batteries, and if you use a diode the additional forward voltage drop is not a problem.
- approx 14" wide metal frame is easy to make mountings or brackets for, and the included bracket is a good one too.
- $50 is what I paid, and that's pretty cheap!
-the frame will collect debris in certain applications, and there are no bypass diodes so anything can land on it and kill the output.
- output drops to nothing on overcast or rainy days, heavy clouds, shadows etc.
- needlessly large border area
- kind of bulky, sharp corners, and the glass seems kind of fragile, for carrying around as a portable trickle charger.
- I couldn't justify a penny more for its output and size.
A couple months after I bought a few of these for about $50 ea. I was able to get a couple 30W panels by Aleko, same width, maybe 4" longer, for $55ea here on Amazon. I'll probably be using the 30W ones on most of my systems from now on.
The bad: Bigger panels have a better value in terms of $/Watt (this one is very expensive by that metric). Additionally, the efficiency is on the low end (~9-10%). The cable junction box is not environmentally sealed. The copper in the included cable had oxidized, indicating questionable sheathing material or cable that had been let sit out for a while... it needed to be cleaned before it could be soldered. An 18" long cable is comically short, and can't practically reach anything else... The holes on the frame are not located in a position where they are easy to attached fasteners to them. They are not accessible from the top of the panel, so screws/bolts must be accessed from the bottom. It should really have some kind of anchoring system. I used UV stabilized cable ties to hold mine to the support frame after I gave up on other fasteners I had. I think that maybe 1/4" captive nuts with matching bolts (to avoiding poking the panel from under and cracking it) would be the way to go.
