Cuba is rapidly turning to Chinese solar technology to combat a worsening energy crisis caused by a near-total oil blockade imposed by the United States, according to reporting by the Financial Times. Faced with widespread blackouts and fuel shortages, Havana is leveraging a surge of photovoltaic imports from Beijing to stabilize its electricity grid and advance an ambitious renewable energy agenda.
The blockade has sharply reduced fuel availability, leaving Cuba’s aging grid increasingly prone to failure. In March, the country experienced two nationwide blackouts within a single week. In response, China supplied approximately one gigawatt of solar panels to Cuba in 2025 alone, helping the island nation reduce its dependence on fossil fuels and avoid further disruption. Cuban authorities have pledged to generate 15 percent of the country’s electricity from renewables in 2026 as part of a broader economic and social plan.
The scale of the Chinese solar program has already begun transforming Cuba’s energy sector. The island now operates 34 solar parks with a combined capacity of nearly 1.2 gigawatts, representing a 350 percent increase compared to 2024. By the end of last year, solar power accounted for roughly nine percent of the nation’s electricity generation. The government plans to expand this capacity further, with 92 solar parks and more than 2 gigawatts of generation expected by 2028. Analysts describe the pace of installation as significant, noting that Cuba is already halfway to its medium-term solar target.
Financing the imports has been opaque, though Cuban officials indicate that part of the technology was donated by China and some was paid for with Cuban-produced nickel. The arrangement reflects Havana’s limited access to global financial markets due to sanctions and highlights China’s growing political and economic involvement in Cuba’s energy sector. Chinese diplomats have publicly criticized the US blockade, pledging further support for Cuba’s renewable energy expansion.
Despite these advances, the benefits of solar energy have yet to reach most Cuban households. Independent reporting indicates that home solar kits remain prohibitively expensive, with the cheapest systems costing up to 100 times the official minimum wage. Consequently, private generators remain more widely used, particularly in businesses and essential services. In addition to solar, Cuba is also building a wind farm with Chinese technology to diversify its renewable energy sources.
Cuba’s energy crisis has been exacerbated by the collapse of oil supplies from Venezuela following the January detention of President Nicolás Maduro. While a Russian tanker recently delivered crude oil—the first shipment in nearly three months—such deliveries remain uncertain and cannot fully offset the shortfall caused by the blockade. US policies have also included threats of tariffs against countries supplying oil to Cuba, further complicating Havana’s access to traditional energy sources.
Amid these pressures, diplomatic signals suggest a possible softening of relations. Cuban President Miguel Díaz-Canel expressed willingness to engage in “serious and responsible” dialogue with the United States following visits from U.S. lawmakers Pramila Jayapal and Jonathan Luther Jackson. These discussions focused on the humanitarian consequences of the energy blockade, which has disrupted hospitals, public transportation, factories, and other essential services. Lawmakers urged immediate negotiations to alleviate suffering and ensure access to energy for ordinary Cubans.
The blockade has intensified Cuba’s broader economic challenges. Tourism, a key source of foreign currency, has virtually halted, and industrial production is constrained by unreliable power. Despite these setbacks, the government continues to pursue renewable energy as a strategic priority, aiming to generate 24 percent of electricity from renewables by 2030, 40 percent by 2035, and 100 percent by 2050. Analysts emphasize that while solar power offers an important lifeline, it cannot fully solve the structural energy problems that have accumulated over decades.
Storage, grid modernization, and financial system reform remain critical bottlenecks. Even with abundant sunlight and favorable conditions for solar and wind power, Cuba faces challenges in scaling up investment and ensuring reliability. International partners have invested in the sector, such as Shanghai Electric’s participation in the Mariel solar park in collaboration with UK-based Hive Energy. This 62 MW project contributes a substantial portion of the island’s electricity and demonstrates the potential for public-private cooperation.
Experts warn that Cuba’s renewable push must be paired with broader economic reforms. While solar power and other clean energy projects alleviate immediate shortages, systemic issues—including limited foreign currency, regulatory barriers, and dependence on external suppliers—continue to constrain growth. Cuba’s path to energy security and economic recovery will depend on the interplay between international support, domestic investment, and ongoing negotiations with the United States.
In the meantime, Chinese solar technology remains a vital lifeline for the island. The rapid deployment of solar parks and the support of international partners have enabled Cuba to maintain critical electricity services amid a challenging geopolitical landscape. Yet analysts caution that renewables alone cannot fully transform the energy sector, and structural changes will be required to modernize the grid, improve storage capabilities, and provide affordable electricity for the Cuban population.
