This blog explores changes in the energy industry from an insider’s perspective as it transitions from the old centralized utility model to the new paradigm of distributed generation.
This blog was previously called Inside the Housing Evolution and focused on energy efficient homes. Ultimately, it’s all linked. Soon, every building will have the potential to generate, store, and sell energy. Welcome to the era of the transactive grid – the greatest shift the electricity sector has seen in over 100 years!

Solar Shingles – Part II

In my last post I described Nanosolar’s thin film solar cells.  DOW has taken this concept one step further with their PowerHouse Solar Shingles.   There isn’t that much information available about this product yet, but DOW claims that they install just like a standard asphalt shingle so they significantly reduce installation costs. 

Although I couldn’t find anything on the DOW website, is claiming that the shingles have 13% efficiency (which is very good!) and 3.5 kW worth of shingles would cost roughly $10,000 installed.  The current installed costs of a 3.5 kW system using today’s technology is approximately $25K-$30k, so this is a real breakthrough!

According to DOW, this product will be available in the US by 2011.  No word on when it will be available in Canada, but given Ontario’s aggressive MicrFIT Solar Incentive program I imagine we’ll be able to get our hands on it soon enough.  Personally, I can’t wait!!  This is the type of game-changing technology that has the potential to revolutionize the housing industry.
