With a distance of about 14 kilometres to our Energy Kiosk in Batima, this is our second project in the District of Bugesera in rural Rwanda and our third solar-powered Energy Kiosk overall. Built in collaboration with the UN-habitat, the kiosk is set in a village of 50 households belonging to Rwandan genocide returnees from Tanzania. In total, our kiosk has the potential to supply 100 households with safe access to electricity and lighting, therefore also including Rutete, a refugee village built very nearby by the Red Cross. The Kavure project was initiated in late 2010 and implemented in September 2011 following a thorough development of the underlying technical and business solution. A follow up mission in January 2012 saw the e.quinox team move the kiosk from its temporary site to a room in a purpose built community centre. On the technical side, six solar panels of 120W each were installed on the roof of the community centre.
Three panels each charge two large storage batteries through a system of charge controllers and inverters. In September of 2012 the kiosk will be updated with our latest data logger solutions allowing remote access to the kiosks statistics from Imperial College London. From a business perspective, a pay-per-recharge model has been determined to be the most feasible solution, as the local community consists mostly of farmers who earn wages on a day-to-day basis. As the next mobile phone charging station is in Batima, a two-hour walk from Kavure, an additional mobile phone charging service has also been established in the kiosk. A customer survey was conducted before implementation and its results used to determine all fees as well as to establish a baseline for current energy usage.
