Remote and rural nature of agricultural activities establish their dependence on off-grid electricity. This study presents an optimal design of a hybrid solar photovoltaic (PV)/diesel power system for the support of irrigation farming and post-harvest cold storage activities in Kadawa village, Kano state of Nigeria. The Hybrid Optimization of Multiple Energy Resources (HOMER) software is used to conduct the techno-economic analysis of the proposed hybrid power system. Simulation results showed that the proposed system can be served by a 25 kW PV system and diesel generator of 10 kW. Other vital indicators in the result included the cost of energy (COE) and net present cost (NPC) which were subjected to sensitivity analysis. Sensitivity variables such as solar irradiance and diesel fuel price effect on this optimal system were conducted. Results show that integrating renewable energy into agricultural activities will go a long way in achieving food security.
