How to start a solar installation business in Nigeria: costs, steps and profit checks

Starting a small solar installation business in Nigeria may need between ₦2.18 million and ₦4.7 million, depending on the setup. The budget assumes equipment is bought against confirmed customer orders, transport is hired, and the founder already owns a phone and laptop. It excludes a showroom and company vehicle.

The estimate covers training, registration, tools, safety equipment, marketing, consumables and operating reserves. It is a planning guide, not an official industry minimum. Stocking equipment raises the requirement. Gennex advertises a 5.12kWh lithium battery at ₦1.06 million. Five units would absorb ₦5.3 million before panels, inverters or rent. Supplier prices need confirmation before purchase.

Training and compliance

Solar customers are buying a working power solution. Training should cover load assessment, equipment compatibility, battery sizing, wiring, protection, rooftop safety and troubleshooting. The Renewable Energy Technology Training Institute advertises a one-month Solar PV Design and Installation course for ₦150,000 and a one-week entrepreneurship course for ₦100,000. Applicants should confirm current fees and practical arrangements. Classroom learning should be followed by supervised fieldwork. Founders without technical backgrounds can manage sales and operations while appointing a qualified technical lead.

The Corporate Affairs Commission lists ₦1,000 for ordinary business-name reservation and ₦20,000 for registration and certified registration documents. Additional charges and professional fees may apply. Business registration does not establish technical competence. The Nigerian Electricity Management Services Agency (NEMSA) has certification requirements for electrical installation personnel and corporate organisations, including renewable-energy work. Entrepreneurs should confirm the applicable category and requirements directly. A training certificate is not a substitute for NEMSA certification.

How the numbers work

A practical entry model combines equipment supply, installation and maintenance within a limited service area. Target essential household appliances, home offices or small shops. Inspect each site before quoting and explain which appliances the proposed system can support. Build relationships with dependable distributors and obtain written warranty terms. Buy against confirmed orders to reduce unsold stock. Customer deposits should match procurement needs. On a ₦3.5 million contract, a 70% deposit provides ₦2.45 million. If equipment costs ₦2.6 million, the installer must fund the shortfall before paying labour or transport.

On an illustrative installation sold for ₦3.5 million, equipment, labour, logistics, consumables, sales costs and a callback allowance total ₦3.05 million. That leaves ₦450,000 towards overhead and profit, not take-home earnings. At monthly overhead of ₦600,000, two similar jobs would produce ₦300,000 before financing costs and tax. One job would leave a ₦150,000 operating loss. These are modelled figures, not guaranteed returns.

After-sales and cash discipline

Maintenance, fault diagnosis and upgrades can generate income between installations. Service agreements should state whether replacement parts and emergency visits are included. Keep equipment records, document testing and explain operating limits at handover.

The federal government has opened applications for a free solar photovoltaic installation training programme. FGN Power Company is organising it with Siemens Energy and the German development agency, GIZ. For a new installer, disciplined procurement and satisfied customers matter more than an expensive showroom. Growth should follow proven demand, sound installations and money actually collected.
