Residential roof shingles with solar panel-like design have recently been unveiled by Dow Chemical. A solar shingle array is said to be 10 to 15 percent cheaper than standard rack-mounted solar panel system and about 40 percent less expensive than building-integrated photovoltaic products.

Although thin-film solar cells have relatively low efficiency versus conventional solar panels, it can still reduce between 40 to 80 percent of a home’s electricity consumption when used.

It can be handled like conventional shingles, which means it can be palletized, walked on or dropped from a roof. Costly installation can be offset because these powerhouse thin-film shingles can be installed by any roofer.

Scheduled for test marketing by mid 2010 to target new-home constructions, these solar shingles from Dow’s Solar Solutions Unit is another breakthrough for environment-friendly products in support of sustainable development. Read the full article here
