Assess before we recommend
We measure loads, roof orientation and shading before proposing any system, so the size we offer matches real use.
About DASSY Enterprise
An energy service company built on renewable engineering, careful project management and long-term customer support.
Our foundation
DASSY Enterprise is an energy service company that was started in November 2007 by NEZERWA Francois d’Assise. He holds a master’s degree in renewable energy engineering and has completed extensive professional and technical training in renewable energy technologies, energy efficiency and energy projects management overseas.
That combination of engineering depth and project experience shapes how we select equipment, plan installations and train the people who will run them.
Where we work
Our head office is in Kigali City. Four further sales branches extend our reach, so customers can compare systems, request site visits and receive spare parts close to home.
How we work
Four habits guide every engagement we take on.
Install to a written standard
Wiring, mounting and commissioning follow documented checklists that the client can review at handover.
Train the local operator
Owners and staff learn how to read the battery state, clean panels and recognise faults early.
Stay reachable after installation
Service visits and spare parts are arranged through our branches, so a fault does not leave a site dark for long.
Since 2007, DASSY Enterprise has been an energy service company headquartered in Kigali City, with four sales branches supporting its customers.
