We’ve recently upgraded our system. It now produces three to four times more electricity than we use on almost all days. We are thus not entirely free of the grid – but have yet to draw from it. At night, (or when overcast) we run from battery power. During each day we sell 15-30 kWh (at a current 20 cents per kWh).
Whether you’re building a new home or adding solar to an existing structure, this is the one book you can’t afford to be without.
Any bookshop, whether online or bricks and mortar, can order copies of Solar Success. Just ask.
