Solar Roof Shingles

Finally, solar roof shingles are on the market and we aren't restricted to those unsightly solar panels. The solar shingles give the appearance of asphalt shingles, but have a thin film of photovoltaic cells to hold the solar energy. And experts seem to think they are more effective than the solar panels.

New technology has doubled the efficiency of solar cells from 7% to 10%, to 20%. They are efficient and durable. It's not an impossible dream to be paid by your local electrical company for excess power being generated by your roof.

Because of the huge amount of heat absorbed by solar roof shingles, you will need to use perforated (ventilated) plywood as an underlayment. But they don't require any additional support.

If you're adding them over an existing roof, the asphalt shingles will be enough to protect the underlayment, but the solar shingles will then be more noticeable.

The shingles have a strong adhesive on the underside which keeps them in place during strong winds (but I don't think they've been tested to withstand hurricanes).

Wiring from the shingles is run under the decking and connected to an inverter. There is no risk of shocks or electrical mishaps, and the wires are concealed.

Solar shingles pay for themselves quicker than solar panels (it'll probably take 8 to 10 years, depending on your climate), and they have an average lifespan of 20 years. They are available in several colors which match standard asphalt shingles, making them hard to detect. And most manufacturers offer warranties.

Although expensive (on a par with solar panels), they obviously (it's the reason you're reading this) have a significant impact on energy consumption.

In addition, they will increase the sales value of your home by at least as much as their cost. If you are serious about adding solar shingles to your roof, look into incentives being offered by local and state governments. Tax credits may even be available.
