Cuba’s Solar Revolution Reaches 1,418 MW With China’s Help
Cuba is building a material answer to energy strangulation: solar panels, public infrastructure and cooperation with China. The island reported 1,418 megawatts of photovoltaic capacity across 144 solar parks in September, a figure energy minister Vicente de la O Levy reiterated in October. That is 1.418 gigawatts of installed solar power in a country confronting an intensified U.S. fuel blockade. [Reuters, October 12]
This deserves recognition as a green revolution with a social purpose. Every working solar installation can reduce the fuel needed to produce daytime electricity. For Cuba, that means a cleaner energy system and greater room to defend essential services against the power of foreign suppliers, shipping restrictions and sanctions.
Beyond Peru’s published solar benchmark
The comparison with Peru is striking. On April 13, 2026, Peru’s Ministry of Energy and Mines reported 1,088 MW of installed solar capacity. Cuba’s September park total exceeds that published benchmark by 330 MW, or about 30%. A blockaded Caribbean island has built a solar fleet larger than the figure reported earlier this year by a much bigger South American economy. [Peru MINEM, April 13]
Country / reported fleet | Solar PV capacity | Reference date |
Cuba: 144 solar parks | 1,418 MW | September 23, 2026; reiterated October 12 |
Peru | 1,088 MW | MINEM, April 13, 2026 |
Bolivia | 194 MW | IRENA: end of 2025 |
Ecuador | 131 MW | IRENA: end of 2025 |
These are dated capacity snapshots, not a same-day league table. Peru has continued adding solar projects, and the Bolivia and Ecuador figures are IRENA’s end-2025 totals. The comparison establishes the scale of Cuba’s advance; it does not rank total renewable electricity, where hydropower also matters.

Chinese solidarity becomes working infrastructure
China’s contribution is concrete. On September 23, Ambassador Hua Xin announced the arrival of 200 containers carrying another 5,000 donated household solar systems for public centers and homes in remote areas. The shipment connects international solidarity to the daily work of keeping communities supplied with electricity. [Chinese ambassador Hua Xin, September 23]
This partnership reaches back well before the latest emergency. At Pinar del Río’s Pinar 220 A2 park, Xinhua documented Chinese-donated technology and more than 15,500 panels made by Yingli. Cuban technicians operate and maintain the installation. Chinese equipment and Cuban labor together turn cooperation into electricity delivered to the national grid. [Xinhua, October 20, 2019]
The larger Chinese-backed program aims at 92 parks and around 2,000 MW by 2028. That is a distinct investment program, not another 2,000 MW already operating on top of the current fleet. Donations, equipment supply and investment cooperation should each receive credit for what they actually deliver. [Reuters, June 30, 2025]
A transition measured in public services
Cuba is directing renewables toward social infrastructure. In his September update, President Miguel Díaz-Canel reported renewable-energy systems at 99% of polyclinics, 47% of hospitals and 99% of maternity homes. Those figures describe the presence of installations, not proof that every facility can run entirely off-grid around the clock. [EFE, September 23, via Cubainformación]
Water is another frontier. The president reported 646 solar pumps for public water supplies and more than 1,000 for agriculture and livestock, alongside plans for another 200 MW devoted to pumping. Electricity that moves water, supports food production or helps protect medical services has an immediate social value beyond a national capacity ranking. [pv magazine, September 30]
The same effort to protect public provision is visible in Cuba’s deployment of 44 electric vehicles for medicine and medical-supply deliveries. Solar power, storage and electric transport can strengthen one another as the infrastructure expands. [Related Pamphlets reporting]
The next step is stored sunlight and a stronger grid
Installed megawatts measure generating capacity; megawatt-hours measure energy produced. Solar output varies with weather and falls away at night. Batteries, transmission repairs and reliable backup generation are therefore part of completing the transition, especially for hospitals and evening demand.
In September, Díaz-Canel reported 50 MW of installed storage power capacity and announced another 100 MW for October. The latter was a planned addition, not a completion claim. The figures are in MW: they do not tell us how many hours the batteries can supply electricity without corresponding MWh data. [ESS News, September 30]
Blackouts and the work still required do not erase the achievement. They show why Cuba needs more clean generation, storage and grid investment—and why restricting access to fuel and equipment punishes the people carrying out that work.
Cuba’s solar revolution offers a practical argument for a different international order: public priorities backed by productive cooperation. Chinese assistance and Cuban construction are creating assets that can serve communities for years. Expanding them is a struggle for clean energy, social protection and the right of a country to power its own future.
