Winston Score History

The full picture

SolarWindow Technologies is a small American company trying to develop transparent coatings that can turn ordinary glass windows into electricity generators. The idea is that buildings could produce solar power from their windows without replacing them with traditional solar panels. Their main target customers would be commercial real estate owners and building developers looking for new ways to generate clean energy.

The company has not yet generated meaningful revenue and is still in the research and development stage, which explains its deeply negative margins. It operates primarily in the United States and remains a pre-commercial business, meaning it has no established moat yet. The central risk is that SolarWindow has been developing its technology for many years without reaching commercial production, and it continues to burn through cash while competing against mature solar panel makers and other emerging transparent solar technologies.
