Solar energy is the most abundant energy resource on the planet: the solar energy that strikes the Earth’s surface in one hour is approximately the same as the amount consumed by all human activities in one year. According to the International Energy Agency (IEA), today, photovoltaic (PV) energy provides 0.1% of the total worldwide electricity production. In the IEA Solar PV Roadmap vision, PV is expected to deliver 5% of the global electricity consumption in 2030, rising to 16% in 2050. Indeed, solar power is widely acknowledged to be the fastest-growing energy industry in the world.

However, in many cases today, solar energy is capped to a certain level (30% of electricity production in many islands). The main reason for the lack of large-scale integration in the electricity mix today is the fact that depending on meteorological events, solar energy can destabilize the electricity grids.

This is why solar forecasting for system operators is crucial. Indeed, the latter are confronted to strong challenges due to photovoltaic energy’s characteristic intermittence and need powerful decision-making tools. The following case study highlights the solutions enabled by Soleka, Reuniwatt’s solar power forecasting tool, in order to optimize the integration of PV power into the grid.
