These will sell out quickly - we highly recommend ordering sooner than later.

Alto Solar’s new, super-thin, lightweight folding solar panel is revolutionizing the 12 VDC folding solar panel market. Connect it to a solar charge controller to charge your 12 volt battery bank, or string together multiple in series for higher voltages and more power!


Perfect for Camping, RVs, Camper Vans, Cottages, Home, Boats, The Beach, Anywhere The Sun Shines!


Constructed from A-Grade mono-crystalline solar cells, the latest ETFE textured lamination film, 23 mm lightweight aluminum alloy frame with fold-out stand - the PV100-FD is state-of-the-art, stylish, comfortable to carry, and extremely efficient.


Advantages of ETFE vs PET Solar Panels

Don't be fooled by the cheap prices of PET flexible solar panels. You get what you pay for! This is a premium product with advanced ETFE Lamination superior to PET solar panels. 


Flexible solar panels use a polymer material, ETFE or PET, to coat and protect the solar cells ("the lamination"). ETFE is widely accepted as being superior and more durable, whereas PET will peel, delaminate, and fail sooner.
