Energy-efficiency consultants, in general, prefer to live in energy-efficient homes. Mudit Saxena was no exception. The new home he and his wife Shweta found was practically perfect in every way. Located in Grupe’s Carsten Crossings Development in Rocklin, CA, the 2,400-square-foot house had SunPower® SunTile® built right into the roof and a fantastic layout plan. But there was a catch. The house was larger than what the Saxenas envisioned. They were concerned that maintaining it would exceed their budget. Fortunately, they realized the solar tiles would translate into big savings. Since moving in April 2007, the Saxenas only pay an average of $45 a month for electricity.
