Cuba Hits 900MW Solar Record With China's Help

Cuba broke its own solar power record on back-to-back days in February 2026, generating over 900MW of clean energy in a single afternoon.

The achievement marks a stunning transformation for a country that has struggled with expensive imported fossil fuels for decades. Just one year earlier, in January 2025, solar power made up only 5.8% of Cuba's total energy generation.

By January 2026, that number had rocketed to 20%. The jump came after Cuba invested heavily in solar infrastructure throughout 2025, with China stepping in as a key partner to make it happen.

China is helping Cuba build 92 solar parks across the island by 2028. Dozens are already generating power, feeding into a grid that has long depended on costly fossil fuel imports made more expensive by U.S. sanctions.

But generating solar power during the day only solves half the problem. Cuba's peak energy demand hits between 7 and 8 p.m., well after sunset, which means the country needs somewhere to store all that daytime solar energy.

China is addressing this challenge by exporting battery storage systems to Cuba. These batteries capture solar energy during sunny hours and release it when families actually need it most.

The partnership extends beyond the national grid too. More than 10,000 standalone solar kits have been installed in homes and buildings not yet connected to Cuba's electrical system, bringing power to communities that have lived without it for years.

Each kit can run a refrigerator, fans, and a TV. For thousands of Cuban families, that means food stays fresh, homes stay cool, and children can study after dark.

The Ripple Effect

China's investment in Cuba goes beyond solar panels. Chinese firms are also building wind farms across the island, tapping into Cuba's natural wind resources and preventing tons of carbon dioxide from entering the atmosphere.

The renewable energy transformation happening in Cuba shows what's possible when smaller nations get the support they need. While headlines often focus on massive solar projects in China or other large countries, Cuba proves that size doesn't limit impact.

In just 12 months, Cuba shifted from heavy fossil fuel dependence to becoming a solar success story, one sunny afternoon at a time.
