We explained and analyzed the need for increased complementarity between Renewable Energy systems.

We developed a methodology that assesses the complementarity between small hydropower and solar PV systems.

An optimization algorithm was developed to maximize complementarity, with small compromises in the solar energy output.

The algorithm uses cloud-based information available online in PVGIS platform (developed in our Institute).

In the case study the complementarity increased by 66.4%, with 10% compromise in solar energy production.
