SolarWindow CEO Letter to Shareholders Describes Market and Commitment to Commercialization

December 10, 2015

Dear Fellow SolarWindow Shareholder:

With your support, we’ve made groundbreaking discoveries and developed possibly the biggest single breakthrough in clean energy –SolarWindow™.

Every day, sunlight streams through billions of windows—more than two million acres of “skyscraper” glass worldwide.

Transparent SolarWindow™ Unit Capable of Generating Electricity

Until now, there has never been a technology able to convert those solar rays into electricity on tall towers like SolarWindow™.

Using SolarWindow™ coatings, entire buildings could be turned into power generators thereby reducing electricity costs by up to 50% per year.

CNBC has said, “SolarWindow™ could give our cities the ability to harvest their own energy needs.”

We have demonstrated before the U.S. Congress, have set records for size and power, and won the Energy Business Review “Energy Innovation Award.”

SolarWindow™ may well be one of today’s most disruptive renewable energy innovations.

Our independently validated modeling shows that when SolarWindow™ is applied to all sides of a 50-story building, the results are:

  • 50 times greater energy than conventional rooftop solar panels
  • 15 times the environmental benefits over traditional rooftop solar energy collectors
  • Electricity generated from natural, shaded, reflected, and even indoor light and
  • A one-year financial payback

In addition, the global push for emissions reductions and clean energy solutions contributes significantly to the market opportunity for the SolarWindow™.

As noted by us in, SolarWindow™ could provide the equivalent reductions in carbon dioxide emissions produced by as much as 770 acres of forest sequestering carbon dioxide when modeled for a 50-story building.

We believe that the future truly is bright, as the use of solar energy keep growing worldwide.

Why this continued growth? The answer is simple–because the adverse environmental impact of traditional energy sources and financial costs of electricity keep increasing.

Commercial buildings alone consume nearly 40% of the electricity generated in the U.S. This is one reason why we’ve targeted commercial buildings as our initial customers.

“This is the kind of product that architects, developers, customers, and energy advocates have long awaited,” said industry executive, and now a SolarWindow Board of Advisors member, Patrick Sargent.

During 2015 we received recognition in numerous other publications including: The Baltimore SunThe New York Daily NewsFast CompanyComputerWorld and National Geographic, to name a few.

Looking forward, 2016 for our shareholders looks to be a landmark year, as we devote our focus on bringing this first-of-its kind technology to market as fast as possible.

In 2016, our mission is to formalize industry relationships, potentially giving us instant commercial reach — a boon for our shareholders.

Of course, you can expect us to continue our long-standing tradition of proactive shareholder outreach to keep you apprised of our major technology and market, and business developments.

I wish you and all those near and dear to you, a wonderful Holiday Season and the very best for 2016 and beyond.

Very truly yours,


John A. Conklin
President and CEO

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.
