Itaipu tests floating solar panels with potential to double plant capacity

2 sources · 22 Apr 2026

The Itaipu plant installed 1,584 floating solar panels in the reservoir as a pilot project to study the feasibility of expanding energy generation. The experiment generates 1 megawatt-peak and functions as a laboratory for future commercial applications. According to technicians, covering 10% of the reservoir with solar panels could generate capacity equivalent to another Itaipu plant.

The Itaipu plant is one of the world's largest engineering works and a symbol of integration between Brazil and Paraguay, with current hydroelectric capacity of 14,000 megawatts. The reservoir occupies a massive area of approximately 1,300 square kilometers, extending almost 170 kilometers from the dam to the opposite end.
