The Solar-Retrofit Nexus: A New Model for School Energy and Mobility.
SPARC+CM integrates three things no programme has ever combined at a school site: solar primary electricity, solar-charged electric school buses, and solar-powered public EV charging, in a single installation, generating four independent revenue streams from Day 1.
The Three-Layer Energy System
A single smart energy management system (SEMS) governs a strict priority sequence, every hour of every day.
The 5/10/5/80 Distribution Model
Every fuel-saving naira from an electric bus is split four ways the moment it is generated.
5%Parents
School bus fee reduction, direct household saving from the first term of operation
10%School Operator
Institutional profit, commercial return on programme participation with zero upfront capital
5%Programme Expenses
Monitoring, carbon credit verification, programme management and reporting
80%Programme Financial Pool
DFI recoverable grant repayment and reinvestment, the engine of programme scale-up
Four Revenue Streams
5/10/5/80 model
Bus Fuel Savings Pool
Generated from Day 1 of electric bus operation. Annual value: ₦1,400,000+ per bus per year at Lagos petrol prices.
70/30 split
Public EV Charging Revenue
Generated from Day 1 of charging station operation. Growing automatically as Nigeria's EV fleet expands.
From Year 2
Commercial Retrofit Workshop Commissions
Revenue from third-party EV conversions at the SPARC+CM Lagos retrofit workshop.
Gold Standard / Verra VCS
Carbon Credits
Three streams: transport emission credits, school energy credits, and embodied carbon credits from circular remanufacturing. First credits from early 2028.
