Great light weight - lighter than the 3 amorphous lower wattage panels I replaced with it!
I have other solar configurations, and this panel is best value of all. I used it with 1,000 watt inverter to power the water filter head on my Aqua Ox which uses 24 volt transformer. I wanted to test this configuration, and also abandon the outlet sharing the 240 volt pump (1/2 leg). I mounted it horizontally to old panels' frame (panels were old and one broken by hurricane). I am very pleased with my "trial" configuration, and will use same for my wired storage shed, which is currently not connected to power source"¦

Should have payed more attention order these about six months ago arrived fast and good shape I grab the box and put them in storage I wanted 400 watts so I saved money and order them again same one but then I noticed the first one I order was different poly and not mono two different solar panels it's my fault for not paying attention

Very durable solar panel that works. Straightforward installation and use. I can't wait to grab a few more to install at my parent's house to get them on the road to self sufficiency.

I was a little concerned with buying such cheap panels so I bought one for testing. It was reproducing 104 watts so I decided to buy 17 more for a total 18. This gave me a 1.8kw array and they have been working excellent. Unfortunately due to my house position, my shed was the only available place right now to install them and they are west facing instead of south. I expect them to perform less than perfect due to not being properly positioned. I am still getting a peak of over 1.5kw which is very good. Most solar panels only produce 80% of their rated amount and these panels are producing more than 80% in a poor configuration.

Due to my geographical location, I get about 5.5 solar hours a day and the panels generate 9.5kwh a day. That is a huge help with the electric bill and I plan on installing a larger array on the garage to make my house netzero.

I highly recommend these panels for a DIY install. There are other solar panels with a better price per watt cost but they are usually 300+watts and difficult to handle without having a large install team. Also, these 100w panels make it easy to configure and they give you more installation options due to their size compared to larger panels.

The build quality of the panels are good. I did not see any defects or problems with them. The only issue I encountered was the first panel I purchased had different mounting hole locations than the other 17. This was a minor issue that was easily fixed with a cordless drill.

These panels are at such a good price that a person can start building their system and keep adding on when they can afford more so they can reach their goal. With the price and quality of these panels, I dont know why everybody is not installing them to save money. I calculated my system ROI to be at 8 years with inverters and all the associated equipment. These panels will end up saving me thousands of dollars over their lifetime!

Good quality works perfectly
