Found solar modules for $0.83/watt. This seller commonly has modules for this cheap. Only downside is you have to do the labor yourself but that's why they're so cheap. I figured that on top of my metro I can fit 102 of these 3x6 modules generating about 183watts max.

Since my metro doesn't agree with 12v and requires the 14.5v to run properly I figure I can put two 12v deep cycle batteries in series to produce 24v then use a voltage divider circuit to bump it down to 14.5v that would feed it to a 12v battery for starting and to run the cars electrical. The solar array would be wired properly to feed directly into the 24v pack.

What would be a good current to design the voltage divider to sustain? probably over 163watts for my metro going by the experiment with the blackfly.
