I super insulated my foundation walls from the outside, (used styro costs peanuts) the mass of sand and soil within my foundation acts as a seasonal earth battery. Cool in the summer, warm in the winter. No moving parts. It is almost that simple. add in oversized trusses in the south facing walls to control the solar gain. free heat, free cool, no moving parts. Storing electricity is not needed if you use it wisely.
