My suggestion would be about 4 small fold down (keeps the Grass Nazi's away) wind generators to help do some charging in the evenings and on stormy days.
Solar is easier to maintain, but don't work at night. So in crunch times you either get a bycycle and a generator or turn it all off, or go wind.
Where I ive I get an early morning breeze and a after dark rain storm. Both will work in a wind generator.
