Im wondering if its possible to 'pull' more watts out of PV solar panels as to charge batteries quicker. The maximum watts from the panels must depend on the load its given. So what if we find the optimum load draw, and create some kind of modified DC-DC converter which cleverly controls the voltages input drop (eg. 8v) as to draw the maximum watts - as well as holding a steady output voltage. (eg.14.5v) Would this work? or, has this been done already?
