As people have become more and more energy conscious, companies and individuals have looked for ways to produce and use energy in a more conservative way. With this movement of green/clean energy, solar energy has been high on the list of alternative energy options.
Recently, solar energy has taken a turn for the better with one of the newest advancements in solar energy, solar roof shingles. Solar roof shingles are a great way to turn a traditional shingle roof into an energy producer. are hybrid shingles that double as a roof shingle that protects the roof from weather and such as well as harnessing the power of the sun and turning it into usable electricity. Solar roof shingles are the new innovated green roofing product of the past couple of years (as of 2013).
What are Solar Roof Shingles?
Solar roof shingles or A.K.A photovoltaic shingles are shingles that use solar technology to create electricity from the sun as well as protect the roof like a tradition asphalt shingle.
How Do They Work?
Solar shingles or a.k.a solar tiles work like traditional solar panels. They use the sun as a power source to create electricity. Each of the solar shingles is comprised of photovoltaic cells. This type of technology has been around for a while and was at first used on satellites in space. The name photovoltaic truly tells what they do. The first part of the word “Photo” means light and the second part of the word “voltaic” means electricity. Thus they take the light and turn it into electricity.
Each of the cells on solar shingles or even a solar panel contains a type of material that is called semiconductors. One of the most used types of semiconductors for photovoltaic cells is silicon. What occurs first with solar shingles is the light hitting them. When this happens a part of the light is captured within the silicon semiconductor. In simple terms what happens is the semiconductor now contains energy and with this energy electrons get loosed and begin to move more freely. Next, these free flowing electrons are acted upon by the photovoltaic cell’s (PV Cells) electric field or fields and are forced to flow in one common direction. This creates a current that can be used for electrical power. This is the basic version of how solar shingles work.
Solar shingles have come a long way. In fact, solar shingles or solar tiles used to be unsatisfactory based on their inability to have a high electricity conversion rate. Because of this, traditional solar panels have generally been the best option for turning a roof into a energy creator.
After the year 2008 the thin-film solar cells had a huge breakthrough when the United State’s Department of Energy achieved a 19 – 19.9% electrical conversion. The previous percentages were just above 10%. This breakthrough came by using a copper indium gallium diselenide or a.k.a CIGS solar cell. Now with this new advancement available solar shingles are much more viable and effective.
How Much Do Solar Roof Shingles Cost?
The amount of money you will initially spend on a solar shingle roof varies but you can expect to pay $30,000 + on a shingle solar roof. With the initial cost you can expect to receive up to a 30% tax incentive from the federal government. Many cities and states also have tax incentive savings available.
Here are some quick answers regarding the cost of solar shingles or a.k.a solar tiles:
The cost of solar roof shingles vary from state to state.
The cost is always custom based on the roof type, area, slope, and so forth.
It depends on how big of a system you will need or want to be installed.
Prices vary based on installer estimates.
Prices vary based on the solar shingle manufacturer or brand type.
Benefits of a Solar Shingle Roof
Here is a basic list of the benefits of having a solar shingle roof.
The homeowners can create their own electricity using the sun’s power.
Homeowners can sell their surplus energy back to the electric company.
Many Homeowners become more energy aware and thus are less wasteful.
Solar shingles also provide protection for the roof (double as a roofing product).
Homeowners know that they are being resourceful which provides a lot of satisfaction for many.
Homeowners can save money in the long run.
Homeowners can lower their electrical bill.
