Solar Energy Generation
SolReina’s solar window captures solar energy, improving the energy efficiency of the building. This technology allows for an aesthetic and functional integration into the architectural design, adding aesthetic value to the property. The idea was born six years ago, as an alternative to photovoltaic installations on roofs, and has proven to be an efficient and practical solution, without the need for complex works or specialized maintenance.
Thermal-Acoustic Insulation
SolReina’s solar windows are designed for use in the external structure of buildings, providing superior thermal and acoustic insulation. The structure of semi-transparent glass is composed of mono or polycrystalline cells, tempered glass, and encapsulated with PVB. The window offers a high light transmission thanks to its high-transparency front glass and a back layer of insulating glass with low energy transmission.
Insulation Features
- Sound Absorption: Range of 38 to 40 dB or more, depending on the thickness of the glass.
- Additional Thermal Resistance: Thermal characterization studies demonstrated effectiveness under both steady-state and dynamic conditions.
- Reduction of Energy Demand: Up to 80% reduction in the use of electric air conditioners on hot days.

Architectural Integration
SolReina offers suitable solutions for the construction sector, allowing architects and engineers to incorporate photovoltaic installations without sacrificing the aesthetics of the building. BIPV (Building Integrated Photovoltaics) panels allow the formation of windows that not only fulfill their aesthetic function but also produce electricity. This type of window integrates functionally and aesthetically into facades, becoming active elements of the building’s electrical installation.
Energy Efficiency
SolReina’s solar windows allow for either electrical or thermal energy generation for self-consumption, depending on factors such as installed surface area, type of photovoltaic panel, orientation, and solar irradiation conditions. A standard solar window can generate between 150 and 225 watts per square meter of solar energy under optimal sun conditions. In many cases, these windows can cover up to 100% of a building’s energy needs, especially when combined with other energy efficiency measures.
