In 2021, Spain added around 3.3 GW of new PV capacity, reaching a cumulative installed capacity of 15.2 GW. As part of the climate law passed in May 2021, Spain introduced new incentives to promote the expansion of the country’s energy storage capacity. The government aims to increase the national storage capacity to 20 GW in 2030 and 30 GW in 2050.


This year, 100 Spanish installation companies participated in the survey. The report provides exclusive insights on the latest developments in the rooftop PV segment in Spain. One section of the report is dedicated to storage solutions.

The latest results show that 64 % of the surveyed installers in Spain offer storage solutions to their customers, compared to 69 % in 2020. 23 % of the installers claim that they are planning to include storage solutions in their portfolio by the end of 2022.

In 2019, installers cited a lack of expertise and high training needs as the main reasons for not offering storage solutions. Now, the main reasons for not offering storage systems are the high prices and the low-profit margins, while lack of expertise and training no longer seems to be a significant issue.

It is a common theme that installers complain about the high prices. In recent years, the cost of a storage system and the lack of incentives were the main challenges to the deployment of storage systems in Spain. The planned expansion of renewable energies, especially wind power and photovoltaics, will lead to a higher demand for energy storage systems. As the new storage strategy includes small-scale as well as large-scale storage systems, the investment grants are expected to boost the installations across all segments and create new opportunities for the Spanish storage market.

Another market for which batteries are relevant is electric mobility. According to the survey results, 35 % of the Spanish installers offer electric mobility solutions in addition to photovoltaics; a further 26 % of those, who currently do not offer electric mobility solutions, want to implement them by the end of 2022. As Spain plans to phase out internal combustion engine vehicles by 2040, the market for electric mobility is expected to grow and further increase the demand for storage systems.
