In the context of growing demand for environmentally friendly and cost-effective energy solutions, Kyrgyz Republic’s agricultural processing sector faces increasing pressure to adopt sustainable practices. This paper presents an economic assessment of integrating solar energy into sugar beet processing, with a focus on the Kaiyndy-Kant enterprise. The study employs a comparative analysis of conventional grid-based electricity and photovoltaic (PV) solar systems, using realistic financial assumptions in Kyrgyz som. The results demonstrate that the adoption of solar panels could reduce energy costs by approximately 70% and lead to a decrease of 8–12% in the final cost of sugar production. Payback periods are estimated at 5–7 years under current tariff structures. Additional analysis includes a comparison with Kaiyndy-Kant Sugar Factory to evaluate the scalability of solar adoption across the sector. The findings suggest that with moderate government support and private investment, solar integration in agro-processing can enhance energy independence, reduce operational risks associated with fluctuating tariffs, and contribute to climate resilience. The study concludes with recommendations for policy reform and financial instruments to support renewable transitions in Kyrgyz agro-industry.
