U.S. Sunlight this year introduced a new product in the form of a low-profile skylight with flexible tubing and a 14″ ceiling lens. Similar to the flat-glass Sun Tunnel by Velux, Skylight Tube ditches the dome-shaped roof lens for a flatter, square design. The new product was designed for simplicity and efficiency and can be installed in a couple hours by a professional or an afternoon by a DIYer (with the right tools).
Pythagoras Solar makes a revolutionary solar-powered window – literally an insulated window with integrated photovoltaics – that has the ability to turn buildings into massive power producers. The company has been testing a pilot project on the south-facing windows of the 56th floor of Willis Tower, formerly known as Sears Tower. If the pilot goes well, Willis Tower could end up with a surface area of up to two megawatts of solar.
Sunnovations, a Virginia-based start-up, is seeing more and more interest in its unique solar thermal technology and just closed a Series A round of financing led by Two Seven Ventures.

The system is relatively affordable, easy to install, and simple to maintain, according to the company.
