Having no solar at all is generally an unforced error for vandwellers. Even [[electrical:12v:alt_and_solar|adding small amounts of panel]] (100w) can make a big difference, and can be added to an [[electrical:12v:alternator|alternator-charged system]] for as little as $100.((100w poly panel on sale for $90, 10A [[electrical:solar:shunt_tweaking|shunt controller]] for $10.)) | Having no solar at all is generally an unforced error for vandwellers.

Don't get me started on people **flat-mounting poly/mono flex panels to the roof of their van**. Maximum cost, maximum power loss due to temp derating, //and// with the bonus of blasting re-radiated heat right through the van roof. It's a crap trifecta. | Don't get me started on people **flat-mounting poly/mono flex panels to the roof of their van**.

| === mixing different panels === |
| |
| Mixing differently-rated panels will always be sub-optimal. People who know what they are doing can minimize the losses. Beginners should either buy identical panels or run different types on separate controllers. |
