Solar Panel Roof Shingles Advantages
In last decade or so solar panel roof shingles have become hottest development in the roofing industry. Their easy to install and convenient to generate electricity for home use. The previous generation of solar panels were large, unwieldy and clunky. They made installation on roof tops difficult and damage to roofing shingles could mean the warranties on them would be voided. Piercing of the roof top to bolt the panels firmly to the roof tops could cause leaks and cracks to the expensive roofing material. To avoid all these hassles the homeowners resisted any pressure to adopt solar technology despite big incentives from state and federal governments.
The rapid progress in solar panel roofing shingles has made them truly state of art. They can be installed on existing panels or replace the asphalt panels. These are also known as photovoltaic shingles and have been designed to look like commonly used asphalt roofing shingles. The interlocking shingles helps them to be integrate with any roofing system with shingles.
In the market today you will find a variety of solar panel roof shingles. There are solid panels which are shingle sized and can be installed directly on the roof or strips of shingles which can be fit on top of convention shingles. Latest technologies use thin film solar cells which look like regular shingles in terms of flexibility and size. Leading manufacturers of solar shingles include big power companies like Atlantic Energy, General Electric, Power Light and Sharp. All these giants have jumped into the building integrated photovoltaics sector big time. Other non-energy players like Dow Chemicals have also entered the solar shingles market to take advantage of high growth rates in the industry.
The cost of installation of these latest shingles has been reduced drastically. The latest installation techniques are so easy to use that fixing the panels is easy and fast. The number of hours of solar panel roof shingles is now around 10 hours whereas a few years back it used to take around 30 hours. This is a major reduction which also saves on installation costs. As the initial cost is reduced there is more incentive to adopt green technologies like solar panel roofing shingles. Aesthetically also, these solar panels look very pleasing to the eye with their dark purplish-blue hue. It blends in with most roofs and homeowners are no longer reluctant to use them for their roofs.
All aspects of design have undergone a great shift with the wiring for the solar panel roofing shingles running underneath the shingles and are completely concealed by them. The wiring can be connected to the inverters by a trained electrician and the roofer. No ugly looking wiring jutting out from the roof tops. You can decide to either distribute the shingles throughout the roofing or keep it located to one side. The best location is south-facing where it can catch the maximum light to convert to energy. Putting all the shingle in one place also makes the wiring easier. Make sure no trees or building cast shadows on solar shingles for maximum efficiency.
