Solar roofs in photovoltaic glass that redefine how we create spaces: the solar panels are built into the structure itself to capture clean, renewable energy.
Photovoltaic systems convert sunlight into electricity using cells made of semiconductor materials. The panels capture the energy and convert it into direct current; an inverter then turns it into alternating current, ready to use in your home or business.
At Kristall we build photovoltaic glass into pergolas, patio roofs and carports, so the same structure that gives you shade also produces energy. Top performance with a clean, architectural look, and no extra panels on the roof.

A photovoltaic glass roof is a glass roof with built-in solar cells that gives shade and generates electricity at the same time. The cells, made of semiconductor materials, convert sunlight into direct current, and an inverter turns it into alternating current ready to use in your home or business. Because the glass is semi-transparent, it lets filtered light through and keeps the rain off like any other roof.
Photovoltaic glass can be built into pergolas, patio roofs, porches and carports, in homes as well as on bar and restaurant terraces. It works best with a good orientation, and in the province of Cádiz it makes the most of the many hours of sunshine each year. In the free assessment we look at the orientation of your space and recommend where to put it.
The difference between a photovoltaic roof and rooftop solar panels is that the structure itself is the generator: no panels are added on top; instead, the solar glass forms the roof of the pergola, porch or carport. That way a single element gives shade, keeps the rain off and generates electricity, with a clean, architectural look. It is a good option when you want solar energy and also want to gain a covered outdoor space.
Yes, a photovoltaic roof generates electricity for direct self-consumption in your home or business, with the option of having any surplus offset against your electricity bill. That energy can also power an electric vehicle charging point, and you reduce your carbon footprint with renewable electricity generated at home. The actual savings depend on the surface area, the orientation and your consumption, and we estimate them as part of the free assessment.
