Cuba Installs 1 Gigawatt of Solar in Just 12 Months

Cuba is racing toward a clean energy future faster than almost any country on Earth, even as its citizens struggle through devastating blackouts.

The island nation installed roughly 1 gigawatt of solar power in just 12 months. That's enough to power more than 1.5 million homes, according to energy think tank Ember.

The transformation has been stunning. In 2023, China exported around $3 million in solar panels to Cuba. By 2025, that number exploded to $117 million.

Cuba and China signed an agreement to build 92 solar parks across the island by 2028. Around 50 are already online, dotted across the country generating clean electricity.

The shift is working. Renewable energy now makes up roughly 10% of Cuba's electricity, up from just 3% in 2024. The government has pledged to reach at least 24% by 2030.

"It's a really, really rapid boom," said Matt Graham from Ember. The speed rivals the fastest solar installations anywhere in the world.

The timing isn't accidental. Cuba has depended on imported oil for decades, first from the Soviet Union, then Venezuela. When those supplies dried up earlier this year, the country faced its worst energy crisis in generations.

Solar offers Cuba a path forward that doesn't depend on fuel imports. The infrastructure lasts decades and needs only sunshine to run. Costs for clean technology have plummeted in recent years, making it more affordable than ever.

President Miguel Diaz-Canel opened the first major solar park in February 2025. Now the panels are spreading rapidly across the island, from rooftops in Matanzas to sprawling parks in the countryside.

The Bright Side

This solar surge shows how crisis can accelerate positive change. Cuba is turning an energy emergency into an opportunity to build a cleaner, more independent future.

The benefits extend beyond Cuba's borders too. China is building goodwill throughout Latin America by supporting renewable energy projects that help countries break free from fossil fuel dependency.

Kevin Cashman, an economist with the Transition Security Project, notes that more renewables mean less dependence on fuel imports. This helps countries gain energy independence and security.

Challenges remain. The solar parks are still small and scattered. Solar only generates power when the sun shines, creating gaps during peak evening demand. Cuba needs more battery storage to solve this puzzle.

The country also needs major investment to fully modernize its aging electrical grid. But the foundation is being laid, panel by panel, park by park.

For ordinary Cubans enduring blackouts, the solar revolution can't come fast enough, but the momentum is unmistakable and the direction is clear.
