Expected ROI of PV energy storage project in Sweden 2026

Which segment dominates the Swedish solar power market in 2024?

The solar rooftop segment continues to dominate the Swedish solar power market, holding approximately 55% market share in 2024.

How much solar will Sweden add in 2024?

Sweden added around 1 GW of solar in 2024, according to provisional figures from Swedish solar energy association Svensk Solenergi. The figures are down on Sweden’s record year for solar in 2023, instead returning to a similar level seen in 2022. Last year’s additions are expected to take Sweden’s combined solar capacity to around 5 GW.

Can solar PV help Sweden achieve its climate goals?

If enabled by energy storage technologies, solar PV may become a helpful component for Sweden to achieve its climate goals. The mention of Sweden however is not because of its climate policy but rather for its geographical and environmental context making it an interesting topic for study when it comes to solar energy.

Can seasonal hydrogen storage increase solar PV Difusion in Sweden?

In conclusion, the idea of seasonal hydrogen storage for electricity might not be the ultimate path to increasing solar PV difusion in Sweden. However, the storage of energy in the more general sense in the form of hydrogen might very well be a driver that can facilitate an increase in solar PV capacity in Sweden.

Can seasonal storage improve the environmental benefits of solar PV in Sweden?

If seasonal storage can enable a larger dispersion of solar PVs in Sweden, the environmental benefits of it will also indirectly be those of solar PVs. In the case that it is, the benefits provided by hydrogen for this purpose may prove to be positive looking over the whole system. Unfortunately, there is a lack of studies investigating this.

Does solar PV contribute to Sweden's energy supply?

Despite this potential, solar PV’s contribution to Sweden’s 508 TWh/yr energy supply is today minimal, accounting for only 0.2 % (1 TWh/yr) of the total energy supply . For Sweden to further tap into this vast supply of energy, some challenges are apparent.
