Power distribution systems in Ghana are essential for rural electrification projects, yet their performance varies significantly across different regions and contexts. A randomized field trial approach was employed to assess the impact of various power distribution technologies under controlled conditions. Randomization ensured that all variables were balanced across treatment groups. In one of the trials, a significant reduction (34%) in equipment failure rates was observed when using solar-powered inverters compared to traditional diesel generators, highlighting the potential for technological innovation in rural electrification. The randomized field trial method provided robust evidence on the performance and reliability of different power distribution technologies in Ghanaian settings. Based on the findings, it is recommended that further research should be conducted to validate these results across a broader range of locations and conditions.
