A Historic Building with a Vision for the Future
With 1,900 m² and nine residential units, the Palacio de Miranda now combines heritage and innovation. Dualsun solar panels generate 67.6 MWh per year, while the building’s annual consumption is 58 MWh. The result? An energy surplus that can be stored in a 61 kWh battery or fed back into the grid, optimizing electricity management and costs.
In Spain, where electricity prices fluctuate hourly, this approach maximizes savings. Thanks to storage and self-consumption solutions, residents benefit from 17% additional savings on their electricity bills.
And that’s not all: the site is also equipped with charging stations for electric vehicles, further enhancing its energy autonomy.
Dualsun and the EXCESS Project: Renovating to Generate More Energy
This project is part of EXCESS, a European initiative testing energy-positive solutions across different climates. Dualsun is also involved in two other demonstrators:
✅ Helsinki, Finland – SPRING hybrid panels for solar heating
✅ Hasselt, Belgium – SPRING hybrid panels
These projects prove that renovating historic buildings with solar energy is both possible and profitable. So why not take the leap and bring solar power to your own renovation project?
