Renewable Energy Solutions for Off-grid Applications

36
german flagship projects
solar energy with a six-month follow-
up. The objective was to establish
Ugandan-German partnerships to
jointly tap the business potential.
Issues such as quality and life-cycle
costs were addressed as well as the
local partners’ learning needs re-
garding the technical and financial
competitiveness of renewable
energy solutions.
