The study aims to determine if Russian energy companies can maintain operations in the solar energy sector without relying on direct state subsidies. Methodologically, the analysis utilizes established investment metrics such as Net Present Value (NPV), Internal Rate of Return (IRR), and Discounted Payback Period (DPP), tailored to reflect the unique technical and economic aspects of Russian solar energy facilities and to evaluate the influence of sector-specific risks on project efficiency, using a rating approach. We examined eleven solar energy projects under ten different scenarios to understand the dynamics of direct state support, exploring variations in support cessation, reductions in financial assistance, and the projects' resilience to external risk factors. Our multi-criteria scenario assessment indicates that, under the prevailing market conditions, the Russian solar energy sector is not yet equipped to operate efficiently without ongoing state financial subsidies. Interestingly, our findings also suggest that the solar energy sector in Russia has a greater potential to reduce its dependence on state support compared to the wind energy sector. Based on these insights, we propose energy policy recommendations aimed at gradually minimizing direct government funding in the Russian renewable energy market. This strategy is designed to foster self-sufficiency and growth in the solar energy sector.
