SolarWindow: Year End 2016 Update

Columbia, MD – December 21, 2016 – SolarWindow Technologies, Inc. (OTCQB: WNDW), the leading developer of transparent electricity-generating coatings for glass windows on tall towers and skyscrapers, today issued its year-end 2016 update.

Below is a statement from John A. Conklin, President and CEO of SolarWindow:

Dear Valued Shareholders:

I’m pleased to report that 2016 was an extraordinary year for SolarWindow. Not only did we receive numerous media accolades for our renewable energy technology, but we were able to raise significant funds, in an otherwise very difficult capital market for smaller companies that has permitted us to move forward on our commercialization pathway. Of course, we have more to do.

Move Over Conventional Solar Panels, Hello SolarWindow™

“…you may soon see a time where skyscrapers and residential high-rises offset their power needs by simply generating their own and even banking energy.”

This is what CCTV America, a division of China Central Television, the world’s largest broadcaster with a reach of more than 1.2 billion people had to say about SolarWindow™.

“…skyscrapers could one day soon be solar energy plants heralding a bright future thanks to energy producing windows,” reported the New York Green Advocate.

‘Invisible Wires’ Grid Transports Electricity across the Surface of SolarWindow™ Coatings

These influential publications are not alone in their assessment of what some are calling an important renewable energy innovation.

Yahoo Tech, a news website operated by Yahoo, which boasts a staggering 204 million unique visits per month, praised the benefits of our technology, along with other important media outlets like Digital Trends, Vox and Renewable Energy Magazine, to name a few.

We are honored to receive these accolades as we continue to execute strategic goals we’ve set for the company.

Earlier in the year, we successfully completed a round of financing to help meet our commercialization goals; and to continue enhancing our product’s performance, increase size, improve reliability and develop new features to obtain important performance certifications required for commercial rollout.

Extraordinary Times

With your ongoing support, we continue our quest to develop products that have the possibility to revolutionize the way we power our buildings around the world.

Imagine, when installed on the acres and acres of glass found on tall towers, SolarWindow™ has the potential to turn these buildings into vertical power generators.

When applied to a 50-story building, SolarWindow™ could avoid more than two million miles of equivalent carbon dioxide emitted by vehicles on the road, reduce electricity costs by as much as 50% per year, provide 15-times the environmental benefits over other roof-top solar PV systems, and achieve a one year financial payback, according to independently-validated engineering modeling.

Typical Insulated Window Frame, Spacer and Edge Seal, and Laminated Glass

Building on our success with developing electricity-generating coatings for windows and flexible plastics, we have recently expanded our product development to include flexible glass – as thin as a business card (only 0.1-millimeter-thick) and flexible enough to be bent without breaking or cracking.

Transparent SolarWindow™ coatings on flexible glass create new product opportunities for curved and non-flat surfaces in windows, automotive, aircraft, military, and specialty product applications.
Since our mid-year shareholder letter, we have passed important tests to demonstrate that specific SolarWindow™ fabrication steps can be manufactured by major window producers — holding up to the stringent requirements of their mass production processes.

The encouraging results are important for our customers, such as window manufacturers, to have confidence that our SolarWindow™ products perform under these ‘autoclave’ conditions for flat, curved, tempered and solar glass.

Old is New Again

With an estimated 430 million square feet of windows in the U.S. alone, we are developing technology to retrofit windows on existing homes and commercial buildings to address that massive potential market.

Topping off an already busy year, we revealed a new, first-ever, ‘invisible system’ for transporting electricity on our window coatings.
Our proprietary SolarWindow™ Intra-Connection System is virtually invisible to the human eye and creates a discreet pattern of microscopic channels that harnesses and reliably transports electricity within SolarWindow™.

This proprietary technology also enables the development of continuous, high-speed, high-volume processes for the goal of manufacturing SolarWindow™ products.

The Power to “Power”

Currently less than 2% of the energy in the U.S. comes from the sun.

The sun produces enough energy in one hour to power our planet for a whole year — that’s like powering a light bulb for every single person on the planet (around 7 billion people), which shines brightly for their entire lifetime.

That’s a lot of power.

The time to bring SolarWindow™ to the world is now.

We look forward to 2017 as we continue innovating and the development of our game-changing technology.

Our goal is to build SolarWindow™ products with incomparable aesthetics that deliver amazing energy and value, and are a cost-effective, energy-generating solution.

All of us at SolarWindow wish you a peaceful holiday season and a Happy New Year!

Very truly yours,

SOLARWINDOW TECHNOLOGIES, INC.

SolarWindow Technologies, Inc. creates transparent electricity-generating liquid coatings. When applied to glass or plastics, these coatings convert passive windows and other materials into electricity generators under natural, artificial, low, shaded, and even reflected light conditions.

Our liquid coating technology has been presented to members of the U.S. Congress and received recognition in numerous industry publications. Our SolarWindow™ technology may generate 50-times the power of a conventional rooftop solar system and may achieve a one-year payback when installed on all four sides of a 50-story building, according to independently-validated power and financial modeling.

Power and Financial Model Disclaimer

The company's Proprietary Power Production & Financial Model (Power & Financial Model) uses photovoltaic (PV) modeling calculations, which 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 degrees 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.
