If you would like to install solar panels, but donít like the aesthetic
appearance of conventional, or older style solar panels then a great alternative
might be solar roof tiles. Also known as solar roof shingles, solar tiles look
just like normal black roof tiles. The difference is they are covered with a
thin film photovoltaic (PV) material which generates electricity.
Solar tile systems can incorporate traditional roofing materials such as slate,
asphalt, metal, and fiber-cement with the solar tiles. In this way, the
appearance is not much different from a regular roof, which makes it
Most solar tiles are generally a dark bluish-purple in color, which makes them
suitable for most homes. Many types are even compliant with areas that have
strict rules regarding historic preservation of local buildings.
Even though one tile by itself doesnít produce much of power (usually between 50
and 200 watts, or about enough to power a small window fan) covering an entire
roof can be quite substantial. In fact, an entire roof covered with solar tiles
can easily generate enough power for your entire home.
However, you still will need to maintain ties to the local power company since
even the sunniest climates have cloudy days, which limits how much power the
tiles can actually generate. Still, the savings i
n power costs should be huge
over a period of time.
The benefits of solar roof tiles over regular solar panels are:
Aesthetics - solar tiles are virtually invisible, as part of your roof.
No extra planning - no need to alter roof lines, colour or pitch. Solar tiles
and slates sit flush with conventional roof tiles.
Reliability - The average lifetime of Solar Roof Tiles is in excess of 20
years. There are no moving parts to the system and very little maintenance is
necessary. Solar Roof Tiles usually have a self locking fixing system that
allows the glass laminate to be easily removed for inspection, cleaning or replacement.
Standard installation - tiles and slates fit with conventional roofing
practice without the need to adjust battens. One solar tile takes the place of
four standard tiles.
No specialist skills - depending on the type of system that you purchase, all
the roofing work can be carried out by the roofing contractor allowing
electrical and plumbing work to follow build programme.
This is an excellent time to go solar powered. There are many excellent state
and federal tax incentives (up to 80% of the cost) and dealers looking to sell
their product in the down economy. You can increase the value of your home,
reduce dependance on the electricity grid and save on utility bills all in one go.
