How Is The Development Of Solar Power Inverter In Cuba?

Cuba has long faced a serious power shortage problem, and frequent power outages have become the norm. The long term sanctions of the United States have made it difficult for Cuba to import the fuel and equipment needed for power. The domestic power infrastructure is seriously aging, and the fuel supply is tight, which has overwhelmed the power system. For example, in February 2025, the failure of multiple generator sets and the shortage of fuel in distributed power stations caused the national power supply to be in urgent need. The Cuban government had to take measures to suspend some teaching and work activities to save electricity.

In this predicament, solar inverters still show broad development prospects in the Cuban market. Cuba has abundant solar energy resources, with more than 2,800 hours of sunshine per year, which provides a solid foundation for the application of solar inverters. In order to solve the energy problem, the Cuban government has begun to seek diversified energy sources in recent years, actively developing and utilizing renewable energy sources, such as solar power. solar power systems can alleviate Cuba's power shortage problem, improve the key force of power supply conditions, and promote Cuba's energy structure to a green and sustainable direction. So today, Xindun will come with you to have a deep understanding of the development of solar power in Cuba? And recommend several high quality solar inverters suitable for Cuban users.

I. Cuba's power structure

Cuba's power supply is still dominated by traditional energy. According to the International Energy Agency (IEA), Cuba's total power in 2023 is about 25 billion kWh. The power structure is highly dependent on fossil fuels, of which oil fired power accounts for 65%, natural gas accounts for 15%, and biomass energy (such as bagasse) accounts for 12%. Among renewable energy sources, solar energy accounts for about 4%, wind energy and hydropower each account for 2%. Although the proportion of renewable energy is still low, the Cuban government has set a goal of 24% of renewable energy in 2030, and has introduced a number of incentive policies, including duty-free import of solar equipment and installation subsidies, to promote the rapid growth of solar installed capacity.

Although the Cuban government has realized the importance of renewable energy and formulated a series of incentive policies, the development of wind power and solar is relatively slow due to technical and financial constraints. In recent years, Cuba's import demand for solar products has been on the rise, which also reflects its determination and potential for development in the field of solar power.

II. Is Cuba's electricity supply stable?

Cuba's power system is not stable. Cuba's power system relies heavily on old thermal power plants. Key facilities such as the Antonio Guitras Thermal Power Plant frequently fail due to aging equipment. The thermal power plant has been in use for decades and is quite old and lacks investment and maintenance and frequently fails. For example, in October 2024, the sudden shutdown of the power plant caused a nationwide power outage. The power outage in some areas lasted for more than 24 hours, becoming the "worst power crisis in 30 years". Throughout 2024, Cuba suffered a total of three nationwide power outages due to fuel shortages and power grid collapse. The average daily power outage duration for Cuban families was as high as 8 hours.

On February 13, 2025, the Cuban Ministry of Labor and Social Security announced that in view of the current domestic power situation, Cuba will suspend all non-essential teaching and work activities on the 14th and 15th. And under the influence of long-term US sanctions, Cuba has difficulty importing fuel and repairing severely aging power equipment, resulting in the inability to replace old units and the delay in the construction of new power stations. 26. Although the government has tried to promote energy transformation through international cooperation (such as China's solar projects), it is still difficult to change the energy structure in which oil-fired power accounts for 80% in the short term. However, Cuban residents or enterprises have begun to install solar power systems to alleviate power outages, achieve independent power supply, and improve electricity conditions.

III. What is the electricity price in Cuba?

Cuba's electricity price system has undergone a series of adjustments in recent years, aiming to optimize the allocation of power resources and promote the transformation of the energy structure. According to the Cuban Ministry of Energy and Mines, starting from March 1, 2024, the electricity price for so-called "large consumers" with a monthly electricity consumption of more than 500 kWh will be increased by 25%. Taking specific electricity consumption data as an example, a user who consumes 600 kWh per month will pay 2,451 pesos per month before the electricity price adjustment, and 2,681 pesos after the adjustment; if the user consumes 700 kWh per month, he will originally pay 3,396 pesos, and after the implementation of the new electricity price, the cost will rise to 3,862 pesos. From the perspective of overall residential electricity consumption, the residential electricity price in Cuba will be 0.720 Cuban pesos per kWh in June 2024, which is about 0.006 US dollars. The rising electricity prices and unstable power supply in Cuba have prompted more households and small and medium sized enterprises to seek more affordable electricity solutions. Solar power systems have become an option considered by many households and businesses in Cuba due to their long term cost advantages.

IV.What is the prospect of solar power in Cuba?

Cuba's solar market has great potential. Cuba is located in the subtropics and has unique lighting conditions. Most areas have a long average annual sunshine time. The abundant sunshine provides a rich energy foundation for solar power. Cuba's average annual solar radiation is 5.5-6.5kWh/m², and the average daily solar radiation power per square meter in Cuba is 5 kWh. Cuba has a large amount of idle land, whether it is open space in rural areas or roofs of urban buildings, which provides ample space for the installation of solar systems.

The latest new energy strategy of the Cuba government, in order to improve energy self sufficiency, Cuba is focusing on the development of renewable energy, and plans to increase the proportion of renewable energy power in the country from the current 5% to 24% by 2030. Solar is the core pillar. This shows that the Cuban government attaches great importance to solar power and provides policy support for its development, which will greatly increase power supply, reduce power outages, improve the stability and reliability of people's electricity use, and make people no longer rely on unstable traditional power supply.

Cuba has formulated relevant plans to build 92 new solar parks by the end of 2028, providing more than 2,000 megawatts of electricity, of which 55 have been included in the 2025 plan. The construction of these solar parks will greatly enhance Cuba's renewable energy power capacity. The promotion of solar power will not only help alleviate Cuba's power crisis, but also drive the development of related industrial chains and create employment opportunities, such as solar equipment manufacturing, installation, maintenance and other fields, providing more employment opportunities for the people and increasing income sources.

Cuba will implement 30,000 sets of household solar power system projects, etc., to provide electricity for families living in remote areas outside the coverage of the power grid, meet basic lighting and electricity needs, and improve their living conditions. Allowing more families to obtain clean energy independently, the people can participate in solar power projects, such as installing solar equipment by themselves, and realize independent power supply, which not only improves the quality of life of residents, but also reduces the overall power burden of the country, and improves the Cuban people's awareness of energy independence and participation in the country's energy transformation.

Cuba exempts import tariffs on solar equipment and provides low interest loans (interest rate 5%). Families can receive a 50% subsidy for installing solar systems. According to the relevant resolution issued by the Cuban government in July 2021, in order to increase the participation of renewable energy in the power grid, individuals are allowed to import solar systems and parts for non-commercial purposes without paying customs duties. It is clearly mentioned that inverters fall into the category of duty-free imports.

V.Which type of solar inverter is suitable for Cuba?

Off grid solar inverter

Off grid solar inverters play an important role in remote areas of Cuba, especially islands and mountainous areas where the power grid is not covered. These areas rely on traditional power grids for high costs and instability, and off grid solar power systems have become an effective way to obtain stable electricity. It converts the direct current(DC) generated by solar panels directly into alternating current(AC) for load use, and stores excess power in energy storage batteries. Although it costs a certain amount to configure energy storage batteries, the overall cost of the off-grid system is still worthwhile compared to long term reliance on expensive and unstable traditional power supply methods. The off grid solar power system generates electricity and stores energy during the day, and can also meet household electricity needs at night or on cloudy days, ensuring the stability and autonomy of electricity use.

On grid solar inverters

On grid solar inverters are more suitable for use in areas of Cuba where the power grid has good coverage and the power supply is relatively stable. In these areas, electricity costs are usually high, and users hope to reduce electricity costs and achieve energy conservation and emission reduction through solar power. On grid inverters can convert the direct current(DC) generated by solar panels into alternating current(AC) and directly connect them to the grid. Users can use the electricity generated by their own solar power system, and the excess electricity can be transmitted to the grid for economic benefits.

Hybrid solar inverter

The hybrid solar inverter combines the advantages of off grid and on grid inverters and has broad application prospects in Cuba. It can not only connect to the mains as a backup power supply when the grid is normal, but also switch to off grid mode when the grid fails, using energy storage batteries to power the load, and can also sell excess power to the grid in on grid mode to obtain revenue. This flexibility allows hybrid inverters to play an important role in both urban and remote areas of Cuba, and is suitable for the overall environment of unstable power supply in Cuba. In addition, users can also choose to configure energy storage batteries according to their own usage scenarios and economic conditions.
