Most portable solar panels have a dirty secret: even if a tiny portion of the panel has any shade on it, the output drops like a rock--sometimes almost to zero!

Shade Stopper solar panels use a patent-pending technology that uses a network of Schottky Diodes to improve our panels' performance in the shade.

Check out this video to see this in action.

Our panels are compatible with most power systems and will consistently provide a substantially higher power output vs our competitors panels.

This is because the performance won't drop like a rock when there is shade--and there's always a little shade!

Well, you may know a place with no clouds to shade the sun.

No leaves or debris that might fall on the panel when you're not watching.

No grass that might shade the bottom row of your panel.

No branches that weren't blocking the panel an hour ago.

No birds that might poop on it.

But even if you go to that place, what if a cell gets damaged? If one cell of a traditional panel gets damaged it can drop the power to almost zero--Shade Stopper panels can take a beating.

Each folding 100 watt panel outputs 18V and 5.6A.

No! Shade Stopper panels will output as much power as a competitor panel will in full sun.

And our panels will provide substantially more power if there is any shade present at all.

The 100 Watt folding panel and our 300 Watt arrays are both water resistant but not water proof. They will hold up to some rain but cannot be submerged or heavily saturated. There are electrical boxes on the backs of them, but they're enclosed in water-resistant protection.

Our 100 Watt flexible panel is 100% weatherproof and can be permanently mounted outdoors.
