With all of the misinformation about solar power, it’s easy to lose sight of the impressive amount of investment that has been made for major solar power plants (not to mention of thousands of rooftop installations). Here’s a great infographic to give you not only the scale but also visuals of the impressive solar arrays in the southwest of the us.

Ask most people in Maine about solar power, and you get what seems like a sensible answer: “We’re too far north for it to really work here.” That also would be the wrong answer.
The world’s leading solar power country today is Germany, which sits at a latitude that runs roughly from the top of Maine to Labrador. Consequently, we get about 33 percent more solar energy than it does.
Over the last 20 years, Germany has installed more solar power than any country in the world, and it isn’t looking back. With more than a million separate solar systems in place, the country on a sunny day can produce as much as half of its energy needs with solar power. Meanwhile, we’re still daydreaming about “too-cheap-to-meter” Quebec hydropower and building pipelines for natural gas that will help as a bridge, but eventually will rise in price as we become more hooked on it.
Germany is headed toward an energy independence that we find only in campaign speeches. And with the money it is not shipping to Saudi Arabia, it’s building new jobs and houses and schools. What a crazy idea, that solar stuff…

It seems so logical – install photo voltaic cells in windows that are bombarded by light in order to both reduce the amount of heat that passes through and generate solar energy. Pythagoras Solar has done just this with their new Photovolatic Glass Unit (PVGU). The double pane glass incorporate optical units, PV collectors and proprietary software to make insulated windows into power generators. Per the company’s data sheet:
Structured as a standard insulated glass unit (IGU) Pythagoras Solar’s photovoltaic glass unit (PVGU) is the only glazing product that combines high density solar power generation with the energy efficiency benefits of an IGU, while providing quality daylighting and preventing direct solar radiation from entering the building. This delivers a new level of design flexibility to the architecture, construction and engineering industries, enabling the creation
of cost-efficient, aesthetically pleasing, self-powered buildings. Pythagoras Solar’s customers are able to realize the benefits of energy efficiency, generation and daylighting in a single, innovative product that meets today’s energy demands.
For the techies among you, here’s how it works (taken from their data sheet):
The windows can generate 120 Wp/m2, per their data sheet.
The one thing you do lose is a clear view out the window. which is why we believe that these are ideally designed for skylights.
