 For this reason the solar + alternator combination is the most common and effective charging approach for vehicle dwellers.  But there are times when one of these (or some other source) might do the majority of heavy lifting, or other forms of charging might be best suited to your particular use case.  For this reason the solar + alternator combination is the most common and effective charging approach for vehicle dwellers.  But there are times when one of these (or some other source) might do the majority of heavy lifting, or other forms of charging might be best suited to your particular use case.
