The off-grid solar photovoltaic electricity production capacity in Portugal has seen a significant uptrend from 2013 to 2023, moving from 2.4 MW to 329.75 MW. Notable year-on-year growth includes a 276.5% increase in 2016 and an 89.77% rise in 2021. Since 2018, the compound annual growth rate (CAGR) has gradually stabilized, reaching 46.07% by 2023. The forecast through 2028 projects a tempered yet steady annual increase at a CAGR of 12%, with a total growth rate of 76.27% over the next five years. This suggests a sustained, though decelerating, expansion in off-grid solar capacities.
Future trends to watch for include the integration of advanced battery storage systems, which could enhance the reliability of off-grid solar systems and further boost adoption rates. Additionally, policy changes and incentives from the Portuguese government will be critical to supporting continued growth in this sector. The monitoring of technological advancements and cost reductions in solar photovoltaic technologies will also play a crucial role in future capacity expansions.
