| Most campervans use [[electrical:solar:gentle_intro|solar]] combined with another charging source, usually the van's [[electrical:12v:alternator|alternator]]. [[electrical:12v:alt_and_solar|This combination]] can be both cheap and highly effective((Isolators are inexpensive, and the combination allows one to run much smaller solar configurations than if one were charging by solar alone)) | Most campervans use [[electrical:solar:gentle_intro|solar]] combined with another charging source, usually the van's [[electrical:12v:alternator|alternator]].

| [[electrical:12v:alt_and_solar|Alternator & solar charging]] enhance each other when used together. Adding alternator charging to solar can significantly reduce [[electrical:solar:sizing|the amount of solar required]] to meet your needs. | [[electrical:12v:alt_and_solar|Alternator & solar charging]] enhance each other when used together.
