I liked these Greesonic panels so much that I wanted to make a quick video review.
I started with the first 100 watt panel a few months ago after getting tired of running an extension for my battery maintainer. Keeping Marine batteries on a maintainer/charger drastically increases their lifespan. For the record, 100 watts is more than enough for this by the way but I wanted to be able to power all my electronics while out at the sandbar or island without draining batteries. So here I am 3 panels later with a rock solid power setup.
Today was the first day I was able to test what they can do with everything left on. (VHF/GPS-FishFinder/Radio/Phone Charger/bait well pump) and the occasional wash down pump to clear the boat of sand. The batteries were un-touched and motor cranked right up after a long day at the island!
After a bit of research I can say I’m glad I found these. Much better quality than those PET panels that scratch easily. These are practically self cleaning. After some rain they good as new. They are so thin and flexible nobody notices they are up there too.
Highly recommend for you guys that like to run on batts for many hours and not have to constantly plug in chargers to maintain their life. Greesonic for the Win!
PS. They are on Amazon.
