An Israeli company hopes to revolutionize the green solutions market with solar windows. The new technology combines electricity production, energy reduction and transparent design.

An Israeli start-up company, Pythagoras Solar, has created the world's first solar window.

According to the firm, the double-pane window embedded with solar cells will allow buildings to generate their own electricity.

The solar window is built from simple plastic pieces to which the solar cells are attached.

It can shade buildings like any blind while still being transparent.

The window reduces air conditioning use and makes the building more energy efficient.

At the same time, it produces solar power which can be used for electricity.

The co-founder and CEO of Pythagoras Solar says the window's benefits are clear.

[Gonen Fink, Co-founder and CEO, Pythagoras Solar]:
"We actually combine triple value, combine multiple benefits - we generate solar power but at the same time we also shade the building and improve the energy efficiency of the building and all this in transparent window that allows people to view the outside of the building and to get a lot of light, day light into the building, further eliminating the need for artificial lighting."

Fink says the four-year-old Pythagoras Solar will announce its first commercial installation in the coming weeks.

The company is in the process of moving into mass production after raising $10 million U.S .dollars in venture capital.

The Chief Technology Officer of Pythagoras Solar says their goal is to revolutionize the energy market.

[Itay Baruchi, Co-founder and CTO, Pythagoras Solar]:
"I think we were looking for a simple solution which will transform the way energy is generated today, solar energy generated today. And this is how we got to this type of very simple optics, very simple manufacturing technologies - not transforming the whole way that the solar industry is manufacturing but upgrading it to a new type of solution which is revolutionized."

Pythagoras Solar's window costs more than a regular window -- about $100 U.S. dollars per square foot.

Fink notes that the return on investment is 3 to 5 years, whereas solar panels take from 7 to 10 years to deliver a return.

Pythagoras Solar currently targets mainly architects and commercial building owners.

They also hope that eco-minded designers and real estate developers will like its green-touch.
