  • The SP-3 solar panel delivers a full 3-Watts of power in a compact and durable size (4.7" L x 9.45"W x .025"H).  For ultimate performance, it should be used to power a single 12V lead-acid battery.
  • Packaging includes:  Circuit box, 3' box-to-lug wire, and a 17' box-to-panel wire.
  • This charger restores and maintains the normal loss of battery power on seldom-used vehicles and equipment stored outdoors, ensuring batteries are maintained indefinitely without the risk of overcharging or overheating.
  • Employs Patented Pulse Technology that minimizes lead sulfate crystals on the battery plates, enhancing the performance, extending battery life 3X, and saving you money in the long run.
  • The design is virtually indestructible and suited for commercial use.
  • Compatible with all 12-volt lead-acid batteries, including VRLA, AGM, gel, and flooded cell types.
  • Featured crystalline silicon photovoltaic cells that maximize solar-to-energy conversion in the smallest possible footprint.
  • Warranty:  Ten-Year Limited Warranty.

Unique Design: SolarPulse utilizes higher-quality crystalline silicon cells pack more power per square inch and have longer life than standard amorphous "thin-film" solar cells. This uniquely designed solar panel is made of highly efficient proven crystalline silicon photo-voltaic cells, encapsulated by a clear polyurethane plastic coating, and mounted on a laminated aluminum substrate back plate that is less than 1/4" thick. 

utdoor Equipment

Doesn’t have reverse polarity protection. I used a different brand of clips ( doesn’t come with clips must be purchased separately) same plug but reversed polarity immediately exploded. They have not returned my email disappointed.

Is Something wrong?

I plugged this thing in a week ago and the red led light on the charging block still hasnt even come on. Its in direct sunlight 10hrs a day

Silvio Gomez

0 issues, keep the battery charged with out being overloaded . I had this item before that's why I bought another.

Charles Million

I was moving one solar panel around between my vehicles. Bought this latest one on sale and now don't have to share among-st vehicles. Great time saver, have not had to jump start my idle vehicles since using these solar panels.

Jeff Hale

I have just gotten it hooked up and should have a more complete review in a week or 2.
