This project had good records of utility usage so we could accurately size a system for 100% solar power."

Tom Kalert, an architect, waited for years to add solar electricity to his passive solar energy efficient home. Tom carefully calculated his average electricity needs for the last 10 years and then Bella designed a system (5kW peak) to meet 100% of his needs (net zero). A year out, he is 200 kWh to the positive and will be selling his remaining solar produced kilowatts back to Xcel.
