SolarWindow Announces Easy Power Connection System for Installation of its Transparent Electricity-Generating Windows

Columbia, MD – May 19, 2015 – SolarWindow Technologies, Inc. (OTCQB: WNDW) today announced plans to replace traditional electrical wiring connections with a simplified next-generation system for collecting the power produced by its see-through electricity-generating windows. In addition to reducing costs, ease of electrical installation will be important to window fabricators, glass installers (i.e., glaziers), electricians, and maintenance personnel.

The replacement of today’s cumbersome methods with the Company’s easy power connection system (‘module interconnects’) is also important for new construction and retrofit applications of SolarWindow™ electricity-generating window modules on skyscrapers and tall towers.

SolarWindow™ products, currently under development, already boast the industry’s fastest published financial payback of less than one year. Last month, the Company’s Power Production and Financial Model was reviewed and validated by a team of third-party, independent engineers and scientists at the University of North Carolina Charlotte Energy Production and Infrastructure Center (UNCC-EPIC).

“We have always had absolute confidence in the financial case for our SolarWindow™ products, and with the support of independent validations, we’re now focused on addressing the very real needs of future customers and end-users.

“Low-cost scale-up and manufacturing, ease-of-installation, and warranties are at the top of our list of ongoing development efforts,” explained Mr. John A. Conklin, President and CEO of SolarWindow Technologies, Inc.

Recently, based on encouraging durability test results that show transparent SolarWindow™ electricity-generating coatings have the capability of meeting or exceeding warranty periods for commercial-grade window products, the Company announced plans to accelerate its durability testing. Working see-through SolarWindow™ modules have set records for both size and power production.

A single installation of SolarWindow™ products on all four sides of tall towers could generate 50-times greater power than traditional rooftop systems and 15-times their environmental benefits.

Module Interconnection: Ease of Manufacturing, Installation, Maintenance

For those who will be involved in the manufacturing, installation, and retrofitting of SolarWindow™ products, today’s announcement could prove especially important.

The newly-announced easy connection system would allow glaziers and electricians to collect electricity from SolarWindow™ modules by connecting building wires anywhere along the entire edge of the glass inside the window frame. Previously, electricity generated on SolarWindow™ modules was collected at individual, hard-wired points on the glass.

As a result of this new interconnection system:

Previously, glass window manufacturers would be required to physically apply electricity collection terminals on to the glass at specific points along the edge. Then, glaziers and installers would need to be especially attentive to ensure that these terminals were within reach of electrical wiring connections, inside a conduit or building wall. Finally, electricians would be required to make a physical connection to building wires at specific electricity collection points on the glass.

“The replacement of soldering points and individual electrical connections with a single power-strip makes it far easier for everyone involved in manufacturing, installation and maintenance – a wonderful engineering approach,” concluded Mr. Provence.

SolarWindow™ products are under development in aesthetically attractive colors in high demand by architects, designers, and building developers. Unique to SolarWindow™, its technology is capable of generating electricity from both natural light and artificial light sources such as fluorescent systems inside offices. SolarWindow™ also works in both direct and indirect or shaded light conditions, making installation possible on all four sides of commercial towers.

For conventional solar systems to produce the equivalent amount of power as a single tower with SolarWindow™ installation would require at least 5-11 years for payback and at least 10-12 acres of valuable urban land.

About SolarWindow Technologies, Inc.

SolarWindow Technologies, Inc. is a developer of next generation electricity-generating SolarWindow™ coatings.

SolarWindow™ coatings generate electricity on see-through glass and flexible plastics with colored tints popular to skyscraper glass. Unlike conventional systems, SolarWindow™ can be applied to all four sides of tall towers, generating electricity using natural and artificial light conditions and even shaded areas. SolarWindow™ uses organic materials, which are dissolved into liquid, ideal for low-cost high-output manufacturing; and is the subject of a patent pending technology.

The Company’s Proprietary Power Production & Financial Model (Power & Financial Model) uses photovoltaic (PV) modeling calculations that are consistent with renewable energy practitioner standards for assessing, evaluating and estimating renewable energy for a PV project. The Power & Financial Model estimator takes into consideration building geographic location, solar radiation for flat-plate collectors (SolarWindow™ irradiance is derated to account for 360 degree building orientation and vertical installation), climate zone energy use and generalized skyscraper building characteristics when estimating PV power and energy production, and carbon dioxide equivalents. Actual power, energy production and carbon dioxide equivalents modeled may vary based upon building-to-building situational characteristics and varying installation methodologies.
