Photovoltaic floor concept

The photovoltaic floor is a construction system that incorporates photovoltaic solar cells in materials used for paving, allowing the generation of electrical energy from sunlight on walkable surfaces. This technology combines energy use with urban functionality, transforming common spaces such as sidewalks, squares, parks and pedestrian areas into active sources of renewable energy.

Unlike traditional solar panels installed on roofs or land, the photovoltaic floor is designed to withstand mechanical loads and environmental conditions typical of pedestrian or vehicular traffic, adapting to different urban and architectural contexts. This feature makes the photovoltaic floor an efficient solution to maximize the use of space in dense urban areas.

Base materials for the photovoltaic floor

The photovoltaic floor is composed of solar panels encapsulated in resistant and durable materials that allow their installation on walkable surfaces. The most common materials include high-strength tempered glass, special polymers and epoxy resins that protect solar cells from impacts, abrasion and adverse weather conditions.

Tempered glass is essential to guarantee the transparency necessary for solar collection and the hardness required to withstand the load of pedestrians and light vehicles. Additionally, a non-slip coating is often used to ensure safety on the floor surface, especially in wet conditions.

Additionally, the frames and support structures are manufactured with metal or reinforced plastic materials that offer stability and facilitate the integration of the system into the urban environment, allowing modular installation and accessible maintenance.

Photovoltaic technology used

The heart of the photovoltaic floor are the solar cells, which convert solar radiation into electrical energy. Crystalline silicon cells are mainly used, due to their high efficiency and durability. However, emerging technologies such as thin film cells are also being explored for specific applications that require flexibility or lower cost.
