CEO Letter To Shareholders

April 27, 2015

Dear Fellow SolarWindow Shareholder:

I’m writing to share some exciting news that has recently captivated our industry and filled our labs and offices with heightened optimism over the past few months.

Why the excitement?

Well, in the words of one leading industry expert:

“Electricity-generating glass which remains see-through marks the $72 billion architectural glass industry’s single greatest breakthrough in a half century.”

Further, the calculated financial payback for our potential customers is less than one year — the industry’s fastest published financial return!

And now, our SolarWindow™ financial modeling has been independently validated by a highly respected team of third-party engineers and scientists.

We believe that we are now well on our way to building commercially-available SolarWindow™ products — one of the most disruptive energy innovations ever, providing:

  • One year published financial payback;
  • 15-times the environmental benefits over traditional rooftop mounted solar;
  • 50-times greater power than conventional rooftop systems; and
  • Electricity from natural, shaded and even indoor light.

What is the potential financial impact for us?

Our SolarWindow™ products are being developed to be installed on all four sides of a skyscraper, turning the entire building into a power generator.

And, since commercial buildings account for 35% of all electricity consumed, this market opportunity is especially significant for you and all of our shareholders.

With such a compelling financial proposition, building-owners, architects, and designers should certainly be motivated to install SolarWindow™ products, when they become available.

Given the worldwide enormity of our breakthrough, it’s no wonder that our award-winning SolarWindow™ technology was demonstrated to the United States Congress.

As CNBC explains, “…SolarWindow™ could give our cities the ability to harvest their own energy needs.”

In closing, I want to let you know that we have changed our Company name to more accurately reflect our technology and commercialization efforts.

We also have embarked upon a new and exciting identity and branding initiative, including the development of a new more stimulating and informative website and social media outreach.

In order to provide updates as timely as possible, we ask that you provide us with your electronic contact information by emailing us at: info@SolarWindow.com.

We also invite you to visit our new website at www.solarwindow.com, and to follow us on Twitter (@solartechwindow), or on Facebook (https://www.facebook.com/SolarWindowTechnologies) for the latest developments and news items concerning your Company.

Please know that your ongoing support is always valued and very much appreciated.

Thank you,

John Conklin,
President & CEO

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

Targeting the estimated 5.6 million U.S. commercial buildings, which consume almost $150 billion in electricity annually, the company’s transparent electricity-generating windows could reduce energy costs by up to 50% and achieve a one-year financial payback for building owners, the industry’s fastest financial return, according to independently-validated company 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.
