Project portraits - Research for the energy transition

PV-diesel hybrid system supplies the 4000 inhabitants on the Caribbean island of St. Eustatius.

Using PV electricity – saves costs for diesel fuel

In off-grid areas, PV electricity can supplement and, as far as possible, replace diesel generators
