Could 2 Million Solar PV Microgrids Cut Nigeria’s Electricity Costs?

I believe Nigeria could expand affordable electricity access through a national network of about two million solar PV microgrids. Each microgrid could serve roughly 50 homes and small businesses, with households that can afford batteries storing electricity for use after sunset. Using an estimate of 90 million buildings, I project that two million small solar plants could create many local businesses and part-time maintenance jobs. The main work would include panel cleaning, basic upkeep, metering and revenue collection, while distribution companies earn a modest commission. A typical plant would need to generate about 250 to 300 kWh daily. I estimate that a 100 kW solar and inverter installation could serve a mix of 50 homes and SMEs, although equipment costs, financing, tariffs, maintenance and actual consumption would determine whether the model is profitable. My argument is that decentralised solar power could offer better long-term returns than some real-estate investments while reducing electricity costs for consumers. Nigeria can study countries with very low electricity prices, while developing a pricing model that is sustainable for investors and affordable for households.
