Solarwindow Tech Stock Price, News & Analysis

SolarWindow Technologies, Inc. (symbol: WNDW) is a Nevada-based company focused on the development of transparent electricity-generating coatings and related processes for use on glass and plastics. According to the company’s public disclosures, its proprietary LiquidElectricity® technology is designed to generate electricity when applied to otherwise ordinary glass surfaces, producing power under natural, artificial, low, shaded, and reflected light conditions. SolarWindow positions its technology as an alternative to conventional solar panels, targeting applications where transparency, aesthetics, and integration into existing surfaces are important.

Business focus and core technology

SolarWindow describes itself as a developer of transparent LiquidElectricity® coatings and processes that can be applied to glass and plastic substrates. When these coatings are applied to glass, they are intended to create electricity-generating windows and other transparent products. The company states that its technology is capable of harvesting light energy from a range of lighting conditions, including natural sunlight and artificial light, as well as low, shaded, or reflected light.

The company has repeatedly emphasized that it targets applications beyond conventional solar panels. Rather than focusing on opaque rooftop or ground-mounted modules, SolarWindow highlights the potential use of its coatings on architectural and other transparent or semi-transparent surfaces.

Target applications and markets

Based on its press releases and SEC filings, SolarWindow is directing its technology toward multiple application areas:

• Architectural glass – including building windows, facades, and rooftops, where LiquidElectricity® coatings could turn large glass areas into electricity-generating surfaces while maintaining transparency and architectural aesthetics.
• Mobility and transportation – the company references potential use in automotive and marine applications, where glass or plastic surfaces could be used to generate power.
• Commercial greenhouse applications – where transparent electricity-generating glass could be used in structures that require light transmission.
• Aerospace and other specialty uses – SolarWindow mentions aerospace and other specialty markets as part of the broad utility it envisions for its technology.

In its descriptions, SolarWindow notes that LiquidElectricity® coatings are intended to provide transparent, aesthetically focused power generation, which the company associates with the potential for faster financial breakeven compared with conventional approaches, while also emphasizing visual appeal for buildings and other structures.

Partnership and collaboration approach

SolarWindow’s public communications indicate a partnership-driven commercialization strategy. The company has highlighted a signed Framework Agreement with Lippert Components, Inc., described as a Fortune 1000 company and a major non-float glass manufacturer. Under this collaboration, SolarWindow and Lippert are jointly pursuing the integration of SolarWindow technologies into select Lippert components to produce transparent electricity-generating SolarWindow–Lippert products.

According to SolarWindow, this collaboration is focused on potential integration of its transparent coatings into products for recreational vehicles, marine vessels, and specialty building products. The company notes that there is no assurance that these development efforts will result in definitive commercial agreements or successfully engineered, manufactured, or deployed products, but it presents this relationship as a key part of its commercialization efforts.

SolarWindow also reports that it is engaged in discussions with additional partners across architectural glass, plastics, specialty materials, and advanced manufacturing, and that it prioritizes working with established manufacturers that already operate global production platforms. The company states that this approach is intended to support scaling, manufacturing readiness, and integration of electricity-generating glass into real-world products.

Intellectual property and technology protection

SolarWindow repeatedly emphasizes its intellectual property portfolio as a central element of its business. The company has stated in earlier communications that its technologies, products, methods, and materials are the subject of numerous granted and in-process trademark and patent filings. It has also highlighted that its technology has been the subject of hundreds of awarded patent claims and additional claims in process in the United States and selected international jurisdictions.

In more recent shareholder communications, SolarWindow reports that it has expanded its intellectual property estate with new patents covering advanced coating formulations, flexible substrate integration, and transparent power module designs. The company notes that these protections include patents related to virtually invisible “power-line” technology, which it describes as micro-scale power-transport lines embedded in glass that carry electricity generated from sunlight while maintaining a clear, unobstructed view through the glass.

SolarWindow states that these patents and patent applications are intended to protect the manufacturing methods, structural device architectures, and aesthetic performance of its electricity-generating glass products, and that it is pursuing a multi-year global IP strategy across key markets including the United States, Europe, and China.

Capital formation and corporate developments

The company has disclosed several financing and corporate events that frame its development stage:

• In June 2025, SolarWindow announced the closing of a $3.9 million capital raise through concurrent domestic and offshore private offerings, involving units consisting of common stock and warrants. The company indicated that these funds are intended to support commercialization initiatives, manufacturing readiness with industry partners, and activities such as engineering, supply chain development, and product validation.
• SolarWindow subsequently filed a registration statement on Form S-1 to register shares issued or issuable in connection with that private placement, describing itself as a smaller reporting company and outlining the resale of shares by selling stockholders.
• Earlier, in December 2021, SolarWindow reported that Light Quantum Energy Holdings, a company owned and controlled by a member of management and his immediate family, had acquired a majority of the company’s issued and outstanding shares from the former controlling stockholder in a privately negotiated transaction.

In its shareholder communications, SolarWindow has also referred to strengthening its balance sheet, deepening its leadership team, and extending its geographic reach through partnerships, while noting that it continues to focus on commercialization of transparent electricity-generating products.
