    Nice setup if you are doing it for environmental / self sustainability reasons. But unfortunately it will never pay for itself. Even less so if we are getting a feed in tariff for micro generation, like many people in the know are saying we will.

    Solar PV works great but have you done any feasibility study for wind at your site?

    2 powerwalls have 27kw of storage.

    Wind would be used to fill a reservoir with turbine only.

    I want it for charging the car and powering the house.
    I spend 2k a year on electricity and oil and about 4k on petrol

    I have access to unlimited free car charger so I could use the car to charge to powerwall

    The cost of power into a powerwall exceeds the cost of power extracted from a powerwall.
