Our people

Our team combines engineering qualifications with hands-on installation experience, so every site is assessed, built and handed over by people who understand both the design and the daily reality of using it.

Our approach

We begin with an energy assessment, agree on realistic goals with the client, and then plan the work in clear stages, keeping the client informed from survey to commissioning.

Since 2007, DASSY Enterprise has grown from a single engineering practice in Kigali into a company with four branches, serving clients who expect dependable solar power and honest advice.
