Solar shingles

Solar shingles could be the latest innovation in aesthetic solar power production systems.  Here we look at what they are and how they work as well as the efficiency and expense of a power system developed using solar roof tiles.

Solar shingles, or solar tiles, could power your house and slash your electric bill too! They can offer a smart, green, and effective alternative for your home, or business.
Solar shingles‚ the aesthetic alternative

Until recently, the only way for households and businesses to generate solar energy has been through the use of solar panels, either mounted on the ground, or fixed to a roof top.  In some cases the panels can appear bulky, or unsightly, and in other cases there may be insufficient room to mount a system on the ground.

Now there is an alternative, with companies offering solar tiles, solar shingles and other building materials that have photovoltaic cells built in, and these can be less conspicuous than traditional solar panels.  The solar shingles, are designed to match existing roof tiles and are available in a number of different colors.

Since the solar shingles are available in different shapes and styles, they can be used to construct a whole new roof, without looking out of place with other houses in your neighborhood.  Alternatively, they can fit straight onto an existing roof, and matched into the existing tiles, or shingles, that are already there.  The available alternatives are increasing all the time, and it is now possible to match solar shingles with terracotta roof tiles that are so popular in the Southwest, or the gray shingles of coastal saltbox cottages.

Solar shingles are a logical step in if we are to expand the market for renewable energy products that appeal to the masses.  By improving the aesthetic appeal of solar energy systems, it allows us the opportunity to reduce our carbon emissions, and look good at the same time.
Cost and efficiency

The good news for consumers that are looking to invest in a green solar energy system; it can be good looking, and cost effective at the same time.

Recent innovations in production processes have seen big improvements in solar energy efficiency, as well as the different styles, and shapes, of solar roof tiles available.  A typical 30 tile section or solar shingles, with a 14 inch solar exposure area and a 3 inch tile overlap, can generate around 900 kilowatts per hour.  This level of efficiency is on a par with some solar panels, and is in fact superior to others.

The initial cost of purchase and installation, is again very similar to traditional solar panels, and local government subsidies and grants are available for individuals that are looking to invest in this innovative technology.  The solar shingles are independent of one another, which gives the added benefit of reduced replacement costs.  If one tile becomes faulty, then it can be replaced whilst the system stays on-line, generating electricity.
Solar roof tiles‚ construction and installation

Silicon photovoltaic cells are bonded to the solar shingles.  The cells capture and convert energy from the sun into electricity by photovoltaic effect.  The shingles are molded from materials that allow a finished product that comes in various shapes and sizes.  The solar roof tiles are easily wired into an existing electricity system, and when the household is not using the full power output, they can actually spin you meter in reverse!

Each solar tile is independent, which makes for easy maintenance, or replacement should you have a problem with one of the tiles.

As technological innovation improves the choices available will increase, as the costs of manufacturing and installation fall.  A future where we can save the planet, and look good while we’re doing it may already be here!
