Between 2017 and 2021, the city of Lisbon quadrupled the cumulative photovoltaic capacity installed in devices, from 2MW to 8MW. Lisbon is the third European city with sunshine and good solar exposure in its building roofs, a maximum of 40% solar exposure which is equivalent to an energy generation potential equal to 95% of the city's electricity consumption in 2016.

Lisbon Solar Strategy aims to reach 103MW (178W per capita) of photovoltaic capacity installed in the city at 2030. This is an important goal to achieve for climate neutrality and to eradicate energy poverty by 2050.

The majority of solar panels in Lisbon is installed in public buildings. Some implemented in buildings of previous construction, such as the Faculty of Sciences of the University of Lisbon. Others are integrated into the architectural design and construction of buildings, such as the Campolide railway station and the Solar XXI building of the National Energy and Geology Laboratory. It is a building designed integrating active and passive technologies, to serve as a demonstration of an energy-efficient building among archi-tects.

In the private sector, the Natura Towers office complex stands out, two buildings that integrate photovol-taic panels on the roofs and facades, along with a rainwater collector and storage system for watering a vertical garden

The possibility of small producers to sell the energy they do not consume to the national electricity grid has proven to be an incentive for the installation of solar panels by private individuals, as well as the granting of subsidies for their financing.

Another important possibility is that producers-consumers and only consumers can create an energy com-munity sharing the production and consumption of electricity. It is from this perspective that the Lisbon City Council has planned the installation of a photovoltaic plant in Carnide, with 2MW capacity, to supply its own buildings and social housing.
