Launched in 2024, the project uses AIKO's Stellar 1N+ ABC modules. The PV modules are installed on a classic fixed-tilt ground-mounted substructure.

Simulation over three decades provides evidence
A 30-year simulation comparing AIKO's ABC modules with TOPCon reference systems demonstrated a consistent performance advantage. The total energy production of the AIKO ABC modules reached 2,564.35 GWh in the simulation, corresponding to an energy gain of 38.54 GWh, or 1.54%, compared to the TOPCon system (Tunnel Oxide Passivated Contact).
The yield increase was 0.80% in the first year, and this advantage expected to grow over time. This long-term performance benefit results in higher overall system output and enhances energy security throughout the plant's operating life, experts say. In addition, the ABC system's high power density and larger active module area mean fewer modules per installed megawatt, fewer strings, less mounting structure, fewer installation components and reduced cabling. These factors further improve the overall efficiency of the solar farm.

Higher returns
In addition to their technical performance, AIKO’s ABC modules offer notable financial benefits, including a shorter payback period of 16 years and 4 months compared to 17 years and 3 months for TOPCon systems, a lower levelised cost of electricity (LCOE) due to higher energy yields and reduced balance-of-system (BOS) costs, and an improved return on investment (ROI) over the project’s lifetime. These advantages make the ABC system a more bankable and economically efficient option for utility developers aiming to maximise long-term value.
Better durability
Designed for harsh and variable conditions, AIKO’s modules are expected to demonstrate excellent durability against typical installation stresses, temperature fluctuations and mechanical loads at the project site. Their uniform ABC design also enhances resistance to micro-cracks and more effectively suppresses hotspots compared to conventional technologies. The standardised size of 2,382 × 1,134 mm and 30 mm thickness ensures compatibility with common mounting systems.

Milestone with 12 percent more electricity yield says chairman
“This project is a milestone for renewable energy in Bosnia and Herzegovina,” says Robert Brajkovic, Chairman of Tibra Pacific. “As the largest operating ground-mounted PV plant in the country, we needed a technology that would perform reliably not only in the lab but also in the field. AIKO's modules deliver 12 percent more energy output and help reduce electricity costs by 3 percent in the first phase compared to the TOPCon setup. As a result, we converted the entire second phase to ABC. Their number-one efficiency and consistency under real-world conditions set a new benchmark for us.” (mg)
