Market Growth Factors
The rooftop solar photovoltaic system market in Spain is rapidly growing because of self-consumption, net metering and removal of the “sun tax”. The elimination of the “sun tax” allows consumers to produce and sell their surplus power more efficiently and economically. In 2024, about 51,306 systems had been installed. Some single-family homes in Madrid had over 70% of their demand covered with solar panels, as well as apartments in urban areas covering 30% of their full demand. The rising cost of grid electricity is driving the growth of rooftop solar in Spain.
Decreases in PV panel and balance-of-systems prices, installation labor costs and improvements in solar manufacturing, permitting and economies of scale have contributed to reductions in total system costs. Personal income tax (IRPF) deductions ranging from 20% to 60% depending on improvement in energy classification, Property Tax (IBI) deductions of up to 50%, and reductions in the Tax on Constructions, Installations and Works (ICIO) are provided by municipalities in addition to the national tax incentives. All of these options yield benefits for consumers.
Storage deployment can complement rooftop solar development. In 2023, behind-the-meter storage deployments in Spain reached 495 MWh, with residential segment accounting for 75% of all behind-the-meter deployments. The systems ensure excess solar afternoon generation can be stored and reused at night or during periods of grid strain. Government rebates, incentives, and emerging energy management systems combined with renewable energy penetration is driving increased battery deployment, improving grid reliability.
