However, his economic analysis is based on MPPT devices being significantly more expensive. If you're making your charge controller yourself, this isn't the case (it's going to be expensive either way). And he assumes that you're going to use panels that are matched to battery voltage, which reduces the available overhead. By using a lower voltage battery, you have more overhead and it's easier to do MPPT. Plus, some of us live in colder places that have short solar days (like WA in the winter). We need all the help we can get. -- Ned Konz http://bike-nomad.com GPG key ID: BEEA7EFE -- http://www.piclist.com hint: The PICList is archived three different ways.
