Price range of micro-modules in West Africa

Micro-modules for solar mini-grids in West Africa typically cost between $0.10 and $0.15 per watt for PV modules, with total system costs influenced by storage, distribution, and installation.Solar Module CostsSolar photovoltaic (PV) module prices have dropped significantly in recent years. In 2023, module prices fell by about 40% to less than $0.15 per watt, driven by cheaper polysilicon and technological improvements. Experts predict that by 2025, module prices could reach $0.10 per watt, and by 2030, $0.07–0.08 per watt . Modules generally account for 20–25% of the total PV system cost, meaning the overall system cost will be higher once balance-of-system (BOS) components, construction, and permitting are included .Mini-Grid System CostsTypical solar mini-grids in West Africa range from 10 kW to 100 kW, with some larger systems possible . Capital expenditure (CAPEX) for mini-grids has declined by about 20% since 2020, reflecting improved efficiencies, but costs remain higher than global benchmarks due to supply chain and import challenges . For small-scale micro-modules, the CAPEX per installed watt can vary widely depending on system size, storage, and local conditions, but a rough estimate for a 10–50 kW micro-grid could range from $1,000 to $2,000 per kW installed, translating to $10,000–$100,000 for a complete micro-module system.Energy Storage CostsEnergy storage is a critical component of micro-modules. Lithium-ion and lead-acid batteries are commonly used, with prices influenced by global lithium trends, shipping, and local import duties . Hybrid solar-storage systems in rural West Africa can deliver electricity at $0.22 per kWh, which is about 40% cheaper than diesel alternatives . Storage systems for small micro-grids (e.g., 50–200 kWh) can add $5,000–$20,000 to the total system cost depending on battery type and capacity.SummaryPV module cost: $0.10–$0.15 per wattTotal micro-module system CAPEX: $1,000–$2,000 per kW installedEnergy storage addition: $5,000–$20,000 for small systemsElectricity cost from hybrid systems: ~$0.22/kWh in rural areas These figures provide a general price range for micro-modules in West Africa, though actual costs will vary by country, system size, and local supply chain conditions .
