Until now I have hesitated to install solar panels. But now it is about time: I want that the refrigerator runs continuously to provide cold drinks.
Got a electronic solar regulator from Amazon, then ordered 4 flexible 100W panels.
First the roof needed to be cleaned.
Then I placed the panels on the roof. I did not want to drill holes, nor did I want to permanently glue them onto the roof... So I used white duct tape to attach each panel at its borders onto the roof surface.
The panels provide enough power to fully charge the two leisure batteries
