Health centre electrification
A solar and battery system that keeps vaccine refrigerators and examination lights running through power cuts.
Solar projects built across Rwanda
A selection of installations and energy projects delivered by DASSY Enterprise since it began operating from Kigali City.
DASSY Enterprise is an energy service company started in November 2007 by NEZERWA Francois d'assise, with its head office in Kigali City and four selling branches.
Recent work
Projects are grouped by the kind of site they served.
Hotel rooftop array
A grid-tied installation that supplies daytime kitchen and laundry loads, with monitoring shared with the owner.
Primary school lighting retrofit
Replacement of old fittings with efficient LED lighting and a small solar supply for evening classes.
Irrigation pumping for a cooperative
Solar pumps and storage tanks that carry water to terraced plots during the dry season.
From survey to commissioning
Each project follows the same record: the site survey, the approved design, test results at handover and a first-year performance check.
How a project progressed
Month 1
Site survey and load study
Metered consumption and roof or ground conditions are recorded.
Month 2
Design approval
The client reviews the system layout, battery choice and expected yield.
Month 3
Installation and commissioning
Equipment is fixed, wired and tested, then handed over with a manual.
Working with our branches
Projects outside Kigali are coordinated through our four selling branches, so local staff can visit sites, collect data and report progress without long delays.
Project notes
Clients who agree to monitoring receive periodic output reports, which help them compare actual generation with the original design.
