Unlike the traditional solar panels, which occupy large spaces on the roofs and are opaque, these windows capture energy in a discreet way and integrated into the architectural design of the buildings. Thus, they represent an innovative and functional solution.
A startup NEXT Energy Technologies, based in California, leads this segment.
According to the website Economic Diary, in March 2025, the company developed the largest transparent photovoltaic window in the world, with dimensions of 101,6 cm x 152,4 cm. In this way, this innovation allows skyscrapers and commercial buildings to significantly reduce electricity costs and increase their energy efficiency.
How does solar window technology work?
A transparent solar window uses a organic photovoltaic coating patented, transforming sunlight into electricity.
This material stands out for its high efficiency and transparency, allowing natural light to enter indoor spaces. In addition, its technology improves the aesthetics and functionality of buildings.
According to the website PV Magazine Brazil, this technology had its first major test in February 2025.
A commercial building in the United States implemented a set of transparent solar windows to evaluate their energy efficiency and impact on cost reduction.
This technology favors commercial and residential buildings who seek sustainable solutions to reduce energy consumption.
Furthermore, it can be installed both in new constructions and to replace conventional glass in existing buildings. Therefore, the application possibilities are broad and advantageous.
Main advantages of transparent solar windows
The adoption of photovoltaic windows brings several advantages to the construction and sustainability sector. Among them, the following stand out:
- Clean energy generation – Reduces dependence on traditional energy sources and reduces carbon emissions.
- Use of large surfaces – Glass facades become electricity generators without compromising the aesthetics of the building.
- Energy Efficiency – Reduces electrical consumption over time, making buildings more sustainable.
- Real estate valuation – The incorporation of sustainable technology increases the value of the property on the market.
- Lower environmental impact – Replacing traditional materials with sustainable solutions contributes to preserving the environment.
What is the impact of solar energy in Brazil?
Brazil, with high solar incidence, has great potential for the adoption of photovoltaic solar windows.
As a consequence, the growth of the market for renewable energy should drive this technology, favoring modern architectural designs and promoting smarter and more efficient buildings.
According to the site Living Cycle, interest in photovoltaic solar energy in Brazil grew significantly in 2024.
There has been a 30% increase in the installation of solar systems in urban buildings. In addition, governments and companies are stepping up investments in solutions that promote sustainability in civil construction.
Thus, the popularization of transparent solar windows in the country can occur quickly, bringing environmental and economic benefits.
The future of solar energy and sustainability
The photovoltaic solar glass represents a significant advance in the revolution of solar energy.
By transforming common windows in clean energy generators, this innovation has the potential to become a global trend. Companies and architects that adopt this solution position themselves at the forefront of sustainability and energy efficiency.
To keep up to date with the latest news about this innovation and its implementation in Brazil, continue exploring trends in the renewable energy e sustainable technology.
After all, investing in these solutions is essential for a greener and more efficient future.
