This project scaled up electricity access via Solar home Systems (SHS) and a commercial sustainable fee-for-service business model in rural Western Uganda. The project aimed to provide 1600 households and businesses with high levels of electricity at affordable monthly prices. For the customer, this meant long-term (> 20 year) maintenance and replacement guarantees for an affordable monthly fee, with no hidden costs. The project grew the customer base to a scale that supports financial sustainable operations.
