Roof Tiles Make It Easier For Homeowners To Go Solar

"At first glance, Paul Rupert's Livermore, Calif., home looks like any other residence. But the 2,900-square-foot house has a powerful secret. Last year, Rupert installed a solar energy system that cut his monthly electricity and heating bill from $400 to $25.

Rather than use traditional photovoltaic panels that mount to a rack and are sometimes considered unsightly, Rupert choose integrated solar roof tiles that interlock with his new concrete roof tiles and lie flat. "Most people don't even notice that it's a solar roof," said Rupert, 67, an aerospace systems engineer.

As the state pushes for more solar-produced power and more builders and sellers realize that solar can help move homes and increase their value, a new generation of solar energy systems is taking hold."
