Cuba Breaks Solar Record Twice in Two Days With China Help

Cuba just proved that you don't need to be a superpower to make giant leaps in clean energy.

In February 2026, the island nation generated over 800 megawatts of solar power in a single afternoon. The very next day, they broke their own record with 900 megawatts, prompting a celebratory announcement from Cuba's Ministry of Energy and Mines.

The numbers tell an even bigger story. Between January 2025 and January 2026, Cuba's solar energy share jumped from just 5.8% to 20% of total energy generation. That's more than tripling their solar capacity in a single year.

For decades, Cuba relied heavily on expensive imported fossil fuels, partly due to prolonged U.S. sanctions that limited energy options. But a new partnership with China is changing everything.

China is helping Cuba construct 92 solar parks across the country by 2028. Dozens are already online and generating power, with more coming online every month.

There's a catch, though. Solar power peaks during daylight hours, but Cuba's electricity demand hits its highest point around 7 or 8 p.m., after sunset. China is addressing this challenge by also exporting battery storage systems to store daytime solar energy for evening use.

The partnership extends beyond large solar farms. More than 10,000 standalone solar kits have been installed in homes and buildings not yet connected to Cuba's national grid. These systems can power refrigerators, fans, TVs, and other essentials that transform daily life for thousands of families.

The Ripple Effect

China's investment isn't stopping at solar. The country is also helping Cuba harness its wind energy potential, with wind farms already operating across the island. Together, these renewable projects have already prevented several tons of carbon dioxide from entering the atmosphere.

The collaboration shows how international partnerships can help smaller nations leapfrog outdated energy infrastructure. Cuba went from energy scarcity to renewable abundance in record time, creating a blueprint other island nations could follow.

For a country that struggled with blackouts and energy shortages, breaking solar records two days in a row signals a brighter, more sustainable future ahead.
