SolarWindow Breakthrough: Electricity-Generating Glass Processed at Commercial Window Fabricator

SolarWindow Technologies, Inc. (OTCQB: WNDW) announced today that its transparent electricity-generating glass has been successfully processed through the rigorous autoclave system for window glass lamination at a commercial window fabricator.

Layered with SolarWindow™ electricity-generating liquid coatings, glass modules were subjected to the extremely high heat and pressure of autoclave equipment located at the fabricator’s facility. Despite the SolarWindow™ modules being subjected to the harsh pressure and temperature conditions, subsequent performance testing confirmed that the modules continued to produce power, paving the way for deployment of the company’s electricity-generating windows.

“This is one of the most important advancements for the commercial manufacturing of SolarWindow™ products, and marks a huge win for all our stockholders, supporters, and scientists and engineers. We’ve long championed the prospect of electricity-generating windows powering skyscrapers and tall towers, which alone consume almost 40% of all the electricity generated in the US,” explained Mr. John A. Conklin, President and CEO of SolarWindow Technologies, Inc.

When clad with electricity-generating windows, tall towers and skyscrapers could become clean power generators. A single SolarWindow™ installation on a 50-story building, for example, could reduce electricity costs by as much as 50% per year, avoid more than two million miles of equivalent carbon dioxide emitted by vehicles on the road, and achieve a one-year financial payback, according to independently-validated engineering modeling.

“I traveled to a custom window fabrication plant on the west coast and personally oversaw senior production staff assemble and position our SolarWindow™ modules inside the autoclave, close the door, and initiate the pump-down cycle,” recalled Conklin.

“Hours later, I witnessed first-hand the moment that our SolarWindow™ coatings and modules emerged unscathed, withstanding the extremely high-pressure and temperature inside. I knew immediately that this was a defining moment for SolarWindow.”

The autoclave manufacturing process uses high heat and pressure to bond layers of glass required for safety and architectural glass. Glass is held in place by an interlayer, between two or more layers of glass. The interlayer keeps the layers of glass bonded even when broken, and its high strength prevents the glass from breaking up into large sharp pieces. The company’s electricity-generating coatings are applied to the inside of these panes and laminate interlayer during manufacturing. The ability of these liquid coatings to withstand the autoclave process is critical to the production of electricity-generating windows.

Today’s announcement follows news that SolarWindow modules recently passed important weather-performance testing after being subjected to more than 200 freeze/thaw cycles. These results confirmed that the company’s electricity-generating coatings withstand real-world weather conditions and achieve long operational lifetimes no matter the outdoor environment that SolarWindow products are exposed to.



The machinery consists of DESERT production machines for high-efficiency DESERT solar modules built specifically for extreme hot climate, such as can be seen in deserts or in tropical areas. Made solely in Germany and built using the latest in DESERT and TROPIC module production, the systems inlcudes all cutting-edge technology.

Certified DESERT solar modules, DESERT containers, DESERT power plants and DESERT manufacturing machinery built using pioneering DESERT and TROPICS technology are now fully set up, and ready to perform. But powering on the machinery has been a long time coming. Up until recently, this advanced piece of equipment had been waiting for clearance at a port in Brazil. Now that the formalities have been dealt with, both J.v.G. Thoma and its customer in Brazil can get production under way.

J.v.G. Thoma GmbH is a company whose vision has always been to harness the infinite power of the sun and convert it into an inexhaustible supply of energy. But a vision such as this requires global reach, and this project has opened new doors. Brazil is not only a gateway to South American cooperation, but also the launchpad to international reach and expansion.

Following the delivery of this initial order, J.v.G. Thoma GmbH will be looking forward to an ongoing collaboration with the Brazilian company. From setup and initial training to setting the scene for a ramp up, J.v.G. Thoma will be there to provide expertise and assistance. Moreover, the company will be jointly responsible, along with the client, for the successful integration of the DESERT solar module factory.

In the future, bigger DESERT power plants will be set up on Brazilian soil, and together with existing turnkey production systems, they intend to take up a large share of the products and assets this sector will possess locally. J.v.G. Thoma plans to build up a local network of sales agents that can extend a premium offering to neighbouring countries in South America. Eventually, the company hopes to be able to expand its customer base to clients in North America.

Hans Thoma, general manager from the Thoma-group, is eager to acquire a substantial market share in Brazil, a growing country with tremendous potential for solar energy output. Having complied with local official procedures (Inmetro, TÜV, Fraunhofer CSP) and cleared the way for future business collaboration, he expresses his hope that the solar industry will henceforth expand quickly.

”Being able to introduce Brazil to the infinite opportunities of a solar industry is a privilege for J.v.G. Thoma GmbH, and one that we are extremely grateful for. At the same time, this placed the ball squarely in our court, and the pressure to get the ball rolling quickly was high. Now that the lengthy initial formalities are out of the way, we can focus on making this project a success.“
