Solar roof shingles are photovoltaic cells disguised as regular roof shingles. At an average of 12 inches wide and 86 inches long, they have 5 inches of exposed area when stacked. While models vary in their mounting requirements, many shingles can be stapled directly into roofing cloth. Because they take the place of traditional asphalt shingles, solar roof shingles don’t need to be shaded by upper roof tiles. This, in addition to the fact that they take up less space, give them the added advantage of optimal placement on the roof. The shingles look similar to regular shingles, so they have more aesthetic appeal to homeowners than solar panels do.
First-generation silicon wafers still comprise 86% of the commercial solar cell market. They make up the sun absorbing material in solar roof shingles and function by generating useable electricity via a p-n junction diode. This configuration enables electrons to escape silicon’s crystalline structure to become electricity. Photovoltaic systems that enable the sun-generated, electrical power to go straight to the grid save homeowners money on battery back up systems that need to be charged.
Output from the solar shingles varies from 13 to 200 watts, with 50 watts being the average. The average installment cost is $10 to $12 dollars per watt. When it comes to cost, however, the amount you spend depends on how much solar electricity you wish to achieve. Solar shingles offer a range of options in terms of wattage and price. Knowing how much area you wish to cover, how many watts of electricity you hope to generate, and whether or not you want to combine roof shingles with panels will help you get closer to determining your spending outcome.
Also keep in mind that though starter costs may be high, advanced solar systems are expected to pay for themselves in savings in about 5 to 7 years. In addition, each state has its own set of monetary incentives for installing energy efficient technology.

SolarCraft installed solar panels for my home. All the electrical work was done for them as well.
This company left me extremely surprised! They were on time, kept their word on everything they said. no surprise charges... NEAT??? They would clean up through out the work day, which is very important to me! The owner made sure I was satisfied with everything.... I really don't have anything negative to say. They build a relationship with me. It was a pleasure serving them coffee in the morning!
