So I just bought a 120W portable solar panel for our trip to Portugal over the winter. Seemed like a good plan until someone told me we can't use it in AIRES etc so this might be a problem. So I thought I would fix it to the roof and buy a converter. But I have no idea what size inverter to buy or how to fix it. Anyone any suggestions? I can't afford to have someone fit it for me. I've been quoted £600 including the kit! My kit only cost me £154. SOOOOOOOOOOO looking forward to driving around Portugal for 4 months!
