JinkoSolar, the global leading PV and ESS supplier, recently officially announced the signing of a 110.42MW Tiger Neo 3.0 high-efficiency module supply agreement with a customer in Bulgaria. The modules will be used for a large-scale ground-mounted power plant project in the country.
Located in the southeastern part of the Balkan Peninsula, Bulgaria features extensive mountainous and hilly terrain. Large-scale ground-mounted power plants are often situated on sloped lands. The undulating topography causes morning and evening row-to-row shading, compounded by local mountain shadows and surrounding vegetation. This presents a significant challenge to module performance under shading conditions. Featuring next-generation TOPCon cell technology, the Tiger Neo 3.0 module achieves a mass-production cell efficiency exceeding 27%, a module front-side efficiency of 24.8%, a maximum power output of 670W, and a bifaciality factor of up to 85±5%. With these industry-leading specifications, it precisely addresses the core challenges of ground-mounted power plants on complex terrain.
High Efficiency and Power, Maximizing Value in Mountainous Areas
Flat land resources are scarce for mountainous power plants, making power generation density per unit area critical to overall project returns. Tiger Neo 3.0 modules enable an 8-10% increase in installed capacity on the same land area, significantly reducing the required quantity of modules, mounting structures, and cables, thereby substantially lowering BOS costs. Combined with an ultra-low temperature coefficient of -0.26%/°C, the modules maintain minimal power degradation even under Bulgaria's high summer temperatures, efficiently converting abundant solar resources into stable green power revenue.
Superior Bifacial Gain, Synergistic Front and Rear Side Performance
The sites of ground-mounted power plants in Bulgaria are typically characterized by light-colored bare soil, gravel, or low grass, naturally providing excellent ground reflectivity. With a bifaciality factor of up to 85±5%, the Tiger Neo 3.0 module offers a significant rear-side power gain advantage over standard industry products, effectively capturing diffuse ground-reflected and sky-scattered light. This yields substantial additional power generation, effectively lowering the levelized cost of electricity (LCOE).
Robust Shading Tolerance, Ensuring Full-Day Output on Complex Terrain
The undulating topography of mountainous sites frequently results in inter-row shading during morning and evening hours, as well as shadows from hills and surrounding vegetation. The Tiger Neo 3.0 module, through its optimized cell layout design, features substantially improved resistance to shading. It maintains highly stable power output under complex shading scenarios, ensuring the power plant operates at full capacity throughout the day.
