Solar panel works fine, even at low lighting I got 4.22 volts.

These panels are half the price of the Radio Scrap equivalent panels and twice the current output. I tested them under ambient lighting and all of them produced close to 5 volts as you can see in the attached picture. In full sunlight I expect they will produce full rated output. I bought 3 of them to make an SLA smart charger so that I would have back up power for my Electronics during a power outage. I could have bought a complete system but it would have cost a couple of hundred bucks for one that actually would work. However, being an electrical engineer I decided to build one to my specs. It will be used to keep a 12v, 20Ahr SLA charged. The electronics will be easy since I already have a circuit design I currently use. The tricky part is mounting the panels so they have proper heat dissipation in full sunlight. This was my first order from Bang_good and I am very impressed with the quality of the items purchased. They took about 2 weeks to arrive but it was worth the wait getting them. I am looking forward to ordering more from Bang_good in the future.
