Solar panels have become a popular solution for water supply in rural areas due to their potential to reduce dependency on fossil fuels and improve energy efficiency. A mixed-methods approach was employed, including surveys, interviews, and econometric analysis to assess the financial viability and health benefits associated with solar-powered water systems. The results indicate that solar panel installations led to a 30% reduction in electricity costs for water pumping operations, translating into an average annual savings of $85 per household. Additionally, there was a noted increase in clean drinking water access from 45% to 72% among the villages studied. The findings suggest that solar panel deployment is not only economically viable but also enhances health outcomes by improving access to safe drinking water in rural Ugandan communities. Local governments and NGOs should prioritise funding for solar-powered water systems in underserved regions, alongside public awareness campaigns to promote their benefits. Treatment effect was estimated with $\text{logit}(p_i)=\beta_0+\beta^\top X_i$, and uncertainty reported using confidence-interval based inference.
