Description
The article evaluates the financial efficiency of a 20 kW class solar photovoltaic power plant installed in a parking structure on the territory of the National Research Institute of Renewable Energy Sources based on real operational data. The plant consists of 45 Green Sun Solar photovoltaic modules with a power of 410 W, and the total nominal DC power of the modules is 18.45 kWp. In January-July 2026, the plant generated 13,600 kWh of electricity. 100% of the generated energy was directed to cover the internal electricity consumption of the institute. The financial assessment used net present value (NPV), internal rate of return (IRR), levelized cost of electricity (LCOE), and discounted payback period (DPP). The baseline calculation resulted in an NPV of 88.7 million soums, an IRR of 28.4%, an LCOE of 542 soums/kWh, and a discounted payback period of 4.75 years. The results showed that on-site consumption of the generated electricity is a cost-effective model for small-scale photovoltaic power plants.
