How solar is sold in Nigeria
The competitor is a generator, not another panel
Nigerian customers rarely buy solar for its own sake. They buy relief from an unreliable supply and from the monthly cost of running a generator, and the sale is settled by comparing what they currently spend on fuel and servicing against a system that would carry the appliances they care about. That makes the load list the single most important document in the process. A quote given before anyone has established what must run, and for how long each night, is a guess that will be revised, argued over and often lost.
Every component is imported and the naira does not wait
Panels, inverters and especially batteries are brought in, so a company's price is a snapshot of exchange rates, freight and clearing on the day it was written. Customers, meanwhile, take weeks to decide, consult a relative, and often pay in instalments or from abroad. A quotation with no expiry is therefore an open invitation to sell at a loss. Discipline about validity, deposits before procurement and payment proofs on the record is what separates companies that grow from companies that are simply busy.
