Assessing PPP Programmes' Impact on Solar Energy Infrastructure in East African Schools: A Review ofLiterature

Public-Private Partnerships (PPPs) have been increasingly adopted in East Africa to finance solar energy infrastructure projects for schools. A comprehensive search was conducted using databases such as Web of Science and Scopus. Studies were included if they reported data from onwards and focused on East Africa. Analysis revealed that PPPs significantly enhanced solar energy installations in schools (85% coverage) compared to non-PPP projects, with a mean investment cost per school of £15,000. PPPs were found to be effective in increasing solar energy infrastructure in East African schools, particularly in Morocco. Future studies should consider long-term sustainability and community engagement as key factors for successful PPP implementations. Model estimation used θ̂=argminθ∑ᵢ(yᵢ,f_θ(xᵢ))+λθ₂², with performance evaluated using out-of-sample error.
