Long time lurker, first time poster. Go easy!
Spent hours online looking for deals on solar panels getting ready for summer camping.
Found these Ridge Ryder solar blankets (they are a clearance item).
Quality looks good, panels are poly crystalline. The regulator is questionable. The store told me they were updated a few months ago due to some issues.
They sell a 10 amp regulator in store for $20 though which is the new model.
They come with a joiner so you can link 2 or 3 sets together with the bullet connector though i would recommend upgrading the 7 amp regulator before trying that.
Many uses and very handy. Free shipping through the online store or going in store they will price match the online price. Compact and lightweight and I've always had good experiences with Super Cheap Auto in store with warranty.
That's a good price if you have a need for a 45w panel (although 2 for 90W would be good), as OP suggested the controllers are best replaced with something better.
