Customer Reviews

Very Positive Experience

Just spent the first few days and nights in the camper with the new panels providing light at night and coffee in the mornings. Thank you Calpha for nice panels and great customer service.

Quality solar panel

I have bought these panels a few times now. They power my shed, automated chicken coupe, a few other things that I don't want to run power to my house for. These panels aren't heavy, they have quick connectors, and easy to mount. And they're quality efficient panels.

Great Panel!!

Bought this as my first foray in to solar for my RV. Couldn't be happier, and will continue to use Calpha panels, controllers and inverters as I continue to upgrade my system. Everything works as advertised, and Calpha makes it easy to understand what I'm doing and why I'm doing it.
