In a firm step towards diversifying and ensuring the sustainability of its electricity generation, the province is consolidating the construction of one of its most emblematic and powerful solar parks to date.

Las Tunas, Cuba.- With an infrastructure of more than 42,522 panels, the 220 KV Substation photovoltaic solar park (PSF, in Spanish) stands as a colossus of renewable energy and a tangible example of the plan to change the country's energy matrix.

Engineer Luis Carlos Mora Quesada, a specialist at the Copextel Las Tunas Territorial Division, told our media outlet that "These photovoltaic modules, each with a power of 560 watts, allow the energy captured to be managed and transformed by seven central inverters of approximately three megawatts (MW) each, key devices that convert direct current into alternating current ready to be fed into the grid.

“To optimize and concentrate production before it reaches the inverters, the facility has a sophisticated grouping system: 18 concentrator boxes that collect and channel energy from thousands of panel strings, maximizing efficiency and facilitating maintenance.”

This project stands out for a significant technical decision: the use of monofacial monocrystalline modules.

"This park has opted for monofacial technology, which is proven and high-performance in optimal radiation conditions. This choice contrasts with that of other, more recent parks that are incorporating bifacial panels, which can generate additional energy by capturing light reflected on the ground or on surfaces behind the panel, a feature particularly advantageous on highly reflective terrain."

“With these dimensions and a total power output of 21 MW, this solar plant is clearly positioned as ‘one of the largest parks currently being built in the country,’” says Mora Quesada.

The completion of this project not only adds MW to the national grid but also consolidates Copextel's team's expertise in the large-scale solar infrastructure installation and management. It reflects a commitment to the energy transition, where photovoltaic technology plays a leading role in creating a local sustainable electricity system for the coming decades.

This farm, with its thousands of panels lined up under the sun, is more than just a power plant; it is a symbol of the direction the country is taking toward a cleaner and more independent energy future.
