Off-grid communities in Tanzania face challenges accessing reliable electricity sources, necessitating innovative solutions to improve quality of life and economic opportunities. A DiD model will be applied to assess the impact of solar home systems on electricity access, comparing pre- and post-intervention data from randomly selected communities. Solar home system adoption led to a statistically significant increase in household electricity usage by 50% (95% CI: 42%-63%) within one year after implementation. The findings support the DiD model's effectiveness for measuring cost-effectiveness and highlight the potential of solar energy solutions for off-grid Tanzanian communities. Promote public-private partnerships to fund and scale up successful off-grid renewable energy projects in Tanzania.
