The Valencia Science Museum has created a 553 kWp photovoltaic installation as part of a broader project to upgrade its air conditioning system.
Installed by Valencian company Yomee, the system integrates 7,664 photovoltaic glass tiles supplied by Ávila-based manufacturer Onyx Solar. The company explained to pv magazine that the tiles, made from crystalline silicon cells, deliver a power output of 129 Wp/m² with an efficiency of 12.9%.
A representative noted that around 6,000 m² of photovoltaic glass tiles in various sizes were produced to fit the building’s structure, with the most common panel measuring 750 mm x 750 mm and weighing 23 kg.
The tiles also offer a visible light transmission of 28% and an external reflection index of 8%. Installed on both the northern and southern cantilevers of the museum, the tiles are designed for minimal visual impact while maximising available space.
The electricity generated will be used for self-consumption, directly feeding the museum’s electrical grid to reduce reliance on external energy sources.
According to the museum, the solar system’s peak production conveniently aligns with its highest air conditioning demand, especially during event schedules.
The installation is expected to generate around 744,823 kWh annually, covering an average of 10% of the museum’s energy needs, with occasional peaks of up to 55%.
In addition, the museum will soon begin work on a geothermal plant, which will connect to the building’s air conditioning system through a closed-loop water circuit using natural aquifers.
Designed with 32 wells, this facility will be the largest of its kind in the Valencian Community, with a thermal capacity of 4,050 kW.
Combined with lighting upgrades and water efficiency measures, the €16m initiative is projected to cut the museum’s non-renewable primary energy consumption by 30%.
