SolarWindow CEO Letter to Shareholders – Join the Revolution

February 16, 2016

Dear SolarWindow Shareholder:

Throughout history, revolutionary products ranging from the lightbulb and printing press to modern flight and mobile phones have benefited society at large and astute investors in particular.

Disruptive thinking has produced life-altering products such as penicillin, computers, and the system that connects billions of people – the Internet. Imagine the world today without the Internet.

Presently, two-thirds of the electricity generated in the US relies on fossil fuels, which are responsible for 99% of CO2 emissions and a leading contributor of global warming. A solution is desperately needed.

Single Greatest Innovation in Clean Energy

An answer to our damaging dependence on fossil fuels does indeed exist. In fact, in a single week, the sun produces 1,000 times the energy oil, natural gas and coal does in a full year – combined.

Our energy needs can actually be met with just 1/10,000th of the sunlight that falls on Earth each day and streams through billions of windows worldwide. Hard to imagine, but true.

Until now, however, no technology has been able to convert those solar rays into electricity like SolarWindow™, making it possibly the single greatest breakthrough technology in clean energy ever.

Transparent Window Produces 50 Times the Energy of PV Panels and Has 1 Year Payback

Our transparent window technology is so revolutionary that it has been presented before members of the U.S. Congress, has won awards and received recognition in many well-known publications.

Unlike any product before, according to validated modeling, SolarWindow™ produces 50 times greater energy than rooftop panels, has a one year modeled payback and even works in the shade.

SolarWindow™ could turn entire buildings into power generators and, as CNBC stated, “give our cities the ability to harvest their own energy needs.”

Developed-in-America Energy Revolution

What began as an idea could soon be on millions of tall towers everywhere. And we owe it to our shareholders and supporters – without their help, the SolarWindow™ would still be just an idea.

To thank our supporters, we are inviting all those who are accredited investors to invest alongside our key shareholders in possibly our most important round of funding.

We encourage you to discover why investing now could quickly make SolarWindow™ amongst the greatest innovations ever. Please visit to learn more.

Your participation in our limited time funding will help bring our Developed-In-America energy revolution to the US market and eventually around the globe.

Limited Time Offering With Special Discounts and Terms

With 5 million commercial buildings in the US alone, which consume almost 40% of the electricity, the SolarWindow™ is the “the kind of product that architects, developers, customers, and energy advocates have long awaited,” said industry executive, and now SolarWindow VP, Patrick Sargent.

Available by invitation only, accredited investors who participate in this funding will not only help towards bringing our transparent electricity-generating technology to market, but will also enjoy special terms, such as warrants to acquire additional shares in the future at today’s price.

Whether you are considering investing $10,000, $100,000 or more, please call (800) 213-0689 or visit to learn how to invest in this limited time offering.

Thank you for your support and welcome to the SolarWindow™ revolution.

Yours truly,

John Conklin

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.
