JinkoSolar Signs 110.28MW Ground-Mount Power Plant Order with Tiger Series Modules in Bulgaria

en.Wedoany.com Reported - JinkoSolar recently signed a supply agreement for 110.28MW of high-efficiency modules in Bulgaria, all featuring the Tiger Series N-type bifacial modules, specifically designated for the construction of a large-scale ground-mount power plant in southeastern Bulgaria. The project site lies in a transitional zone between continental and Mediterranean climates, with abundant solar resources suitable for large-scale ground-mount plants. However, the terrain is notably undulating, with hills and valleys interspersed, making morning and evening array shading and terrain-induced shadowing unavoidable. In summer, intense convective weather is frequent in the afternoons, with fast-moving cloud clusters causing significant fluctuations in irradiance over short periods. The complex light conditions pose a comprehensive challenge to the modules' low-light response, shading resistance, and bifacial gain. The Tiger Series modules address the owner's demand for certainty in the plant's full-lifecycle returns through three core performance strengths.

The project site's surface is predominantly light-colored sandy soil and exposed rock formations, providing favorable reflection conditions. The Tiger Series modules achieve a bifaciality ratio of up to 85±5%, allowing the rear side to effectively capture ground-reflected light and sky-diffused light, generating additional power gains during both peak sunlight at noon and oblique-angle irradiation in the morning and evening. The combination of high front-side output and high rear-side gain ensures that every inch of usable light energy across the undulating terrain is fully converted.

Southeastern Bulgaria is predominantly sunny, yet the low-irradiance periods at dawn and dusk remain integral to the plant's daily power generation. The Tiger Series modules maintain a high power output ratio under low-light conditions, with significantly superior low-light response compared to conventional products. They continue to deliver substantial power output even when morning and evening sunlight is insufficient, effectively extending the daily generation hours and ensuring the plant consistently contributes stable electricity throughout the full spectrum of solar intensity from weak to strong.

Shading sources at sloped-terrain plants are diverse and difficult to fully avoid. Shadows cast by hills during dawn and dusk, inter-row array shading, and localized dark areas formed on module surfaces by fast-moving clouds can all trigger the "short-board effect" in conventional modules. By restructuring cell layout and electrical architecture, the Tiger Series modules achieve a multiplied improvement in shading resistance. Even when partially shaded, they maintain high current balance within the string, minimizing shading losses to the lowest possible level and ensuring the plant continues to operate efficiently under variable light conditions.
