The solar energy industry isn’t a baby anymore, is it? Over the years, solar energy systems have grown up.  Not only are solar energy systems more efficient, but newer options are available to consumers as well, and the folks who install them all for you are a lot better at what they do.Solar Photovoltaic Shingles

Roofing companies are just one example of how solar technology development has changed business. Solar isn’t just about solar panels anymore.  Photovoltaic shingles are being requested by businesses and homeowners more and more these days.

Photovoltaic roofing materials have been available for about 5 years.  PV roofing tiles and shingles have embedded solar converters, and look similar to regular roofing materials.  They keep out the sun and rain, and are installed in much the same way as traditional roofing.  The shingle strips are connected in such a way that if one strip goes out, the remaining surface continues to work.  Peak production for the strips is obviously mid-day.

Solar panels, however, are still the most widely used system for collecting solar energy, and some states are making a push to decentralize power production away from large plants and onto your rooftop.  Duke Energy, for example, plans to install up to 850 solar panels on homes, schools, stores, and factories throughout North Carolina, at a cost of $100 million. The idea, obviously, is to produce the power where it is used, and Duke Energy sees the potential in doing business this way.

Of course, the upfront cost of installing photovoltaic shingles and solar panels is still high, but tax credits can cover as much as 65 percent of your solar energy system. Some industry experts, however, predict that by 2020 the cost of producing solar power will be roughly the same as that of conventional electricity production. 

We will see ultracapacitors used more with photovoltaic shingles in new home designs... it's not too far away now..

$100,000,000 for 850 panels??? They need to get another PV source. They're paying about 1000 times more than they should.

I think he means "installations" not panels.

Of course, the cost of regular electric is subsidized (as is oil) so the true cost of energy is what solar electric costs now. If solar were subsidized like oil it would be 30% cheaper. If the solar energy industry had the investments that coal, oil and nuclear did then we would not need coal, oil or nuclear.

Just how much is each energy source subsidized? Do you have any numbers to back that claim up?
