4 Solar panels on the roof recharge the 15 batteries on the Mazda
Electric Car if they are only half empty If the Mazda is near empty it
takes all 8 panels al day long to charge. If wind is blowing the wind
charger makes the charging go faster. The other 4 panels power the 110
volt appliances in the house thru an inverter. A 5 HP propane,
Hydrogen hybrid DC generator can be used for a 1 hour quick charge.
