In Ghana, power distribution systems are critical for economic development but often face challenges in reliability and efficiency. A randomized controlled trial was conducted among 200 randomly selected households across three regions. Adoption rates were measured over six months using a pre-defined protocol. In Region A, adoption rate of solar-powered equipment was found to be 45% with a confidence interval of (38%, 51%). The randomized field trial revealed significant variations in adoption rates across regions and highlighted the importance of local socioeconomic factors. Policy makers should consider regional differences when implementing power distribution systems, emphasising educational campaigns to improve understanding and acceptance. The maintenance outcome was modelled as Y₈ₓ=₀+₁X₈ₓ+uᵢ+₈ₓ, with robustness checked using heteroskedasticity-consistent errors.
