Solar Roof Shingles

solar Shingles TilesAs 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.


New Technology

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.

Here are some quick answers regarding the cost of solar shingles or a.k.a solar tiles:

  1. The cost of solar roof shingles vary from state to state.
  2. The cost is always custom based on the roof type, area, slope, and so forth.
  3. It depends on how big of a system you will need or want to be installed.
  4. Prices vary based on installer estimates.
  5. Prices vary based on the solar shingle manufacturer or brand type.

Questions To Help Determine Your Price

  1. How big is your roof?
  2. What is the pitch of your roof?
  3. What state and city do you live in?
  4. What brand of solar shingles do you want to use?
  5. What size of a system do you want or need?
  6. Does your state provide tax incentives?
  7. Does the power company buy back electricity and if yes, at what price?
  8. Do you know a local certified installer of solar shingles?
  9. Do you need an entire new roof or are you just replacing some existing shingles with solar shingles?
  10. Will you need to remove trees to give your roof more sunlight?

List of Solar Shingle Manufacturers

Dow’s Powerhouse Solar Shingles

The most well known and major player in the solar shingle market is Dow’s Powerhouse solar shingles. Although Dow officially launched their powerhouse solar shingles in October of 2011, these types of shingles have existed before but because of past inefficiency they have not become widely excepted. Dow has rightfully taken advantage of the breakthrough technology of CIGS solar cells. These thin-film solar cells do a fantastic job at turning sun light into usable electricity at a 19.9% conversion.

The powerhouse solar shingles are installed as easily as regular asphalt shingles but they also generate 12 watts of power per square foot of roof. These shingles are not tied into a battery backed up system but use the grid. Because they are tied to the grid they can actually give power back and earn the home owners money. The shingles are becoming more and more available in various markets but are not yet available in all 50 states in the U.S. The first state to have the Powerhouse solar shingles available was Colorado in 2011.
