64 MW Stolac Solarni Park PV plant in BiH begins power generation

The 64 MW solar power plant Stolac Solarni Park, located near the city of Stolac in the Herzegovina region of Bosnia and Herzegovina, has been connected to the grid and has begun generating electricity. No further details have been disclosed, but the facility appears to be an extension of Hodovo, the largest photovoltaic plant in the country.

“We are proud to announce the successful grid connection of the Stolac Solarni Park photovoltaic plant in Bosnia and Herzegovina,” China-based solar technology company AIKO said in a statement. Developed by Tibra Pacific, the project has entered full operation and is now supplying clean solar power to the regional grid, according to the statement.

The company hailed Stolac Solarni Park as a major milestone, as AIKO and Tibra Pacific completed the grid connection of Europe’s first utility-scale solar project based on Back Contact technology. AIKO claims to have invented N-Type ABC (All Back Contact) technology.

AIKO disclosed few additional details about the project.

Stolac Solarni Park forms a key part of the largest grid-connected ground-mounted PV installation in BiH to date

With an installed capacity of 64 MW using AIKO modules, Stolac Solarni Park forms a key part of the largest grid-connected ground-mounted PV installation in BiH to date, AIKO noted. Originally launched in 2024, the project adopted AIKO’s innovative Stellar 1N+ ABC modules. The system is built on a fixed-tilt structure with an optimized layout to maximize land use.

According to Robert Brajković, Chairman of Tibra Pacific, the project marks a milestone for renewable energy in BiH.

Brajković: We needed technology that performs not just in labs, but on-site as well

“As the country’s largest operational ground-mounted PV plant, we needed technology that performs not just in labs, but on-site as well. AIKO’s modules delivered 12% more energy output and helped reduce electricity costs by 3% in the first phase, compared to the TOPCon setup. As a result, we transitioned the entire second phase to ABC. Their No.1 efficiency and consistency in real-world conditions set a new benchmark for us,” he said.

AIKO noted that Stolac Solarni Park represents more than a utility-scale project – it is a symbol of regional commitment to clean energy. “By deploying advanced PV technology at scale, the project supports BiH’s energy diversification goals,” the company said.

The two firms did not provide any additional information on the projects.

The largest photovoltaic plant in BiH is Hodovo, with a capacity of 92.5 MW, according to the Independent System Operator in Bosnia and Herzegovina. It is operated by Eco-Wat, a local firm owned by Tibra-Pacific. In December 2021, Eco-Wat said it intended to install a 150 MW solar park near Stolac. It appears the project has now reached its planned capacity.

In the same municipality in May, construction was launched on another solar project, with a capacity of 125 MW.
