Achieving Economies of Scale in the Nigerian Solar Value Chain

The report argues that achieving economies of scale in Nigeria's solar sector requires a transition from accelerated importation to local assembly and eventually local manufacturing. It identifies that approximately 7 million Nigerian households are ready for immediate solar home system (SHS) deployment based on geospatial data. The analysis demonstrates that combining four key enablers—import tariff waivers, reduced cost of debt, increased plant capacity, and product subsidies—could reduce SHS prices by 34% and increase the number of households able to afford these systems by 288%.

• Geospatial analysis identifies approximately 7 million Nigerian households ready for immediate deployment of solar home systems (SHS). These households meet three criteria: the ability to pay for Tier 2 electricity (at least 50Wp), living in communities where at least 30% of homes are unelectrified and are more than 5km from a mini-grid, and residing in communities where over 50% of households are determined as high or moderate repayers.
• The report proposes a three-phase systematic approach to localization: first, 'Accelerated Importation' (short term, ~9 months) using semi-knocked-down kits; second, 'Local Assembly' of key components like PV and batteries (short to medium term, ~10–22 months); and third, 'Local Manufacturing' of components such as silicon cells (long term, ~22-36 months).
• Economic modelling shows that the combined application of four enablers—import tariff waivers, reduction of the cost of debt from 12% to 5%, increasing plant capacity from 20MW to 100MW, and a 20% product subsidy—would result in a 34% reduction in the price of SHS and a 288% increase in the number of households able to afford the systems.
• The report identifies significant barriers in the current value chain, including a high dependency on imports from China, inconsistent tariff applications where components in SHS kits attract higher duties than individual panels, and a lack of strict regulations leading to a proliferation of low-quality imports.
• Localization of the solar value chain is projected to create substantial socio-economic benefits, including the creation of 193,053 jobs and the saving of 356,486 metric tons of greenhouse gas emissions.
