Quick answer: A complete solar home system in Nigeria combines solar panels, an inverter, batteries, protection equipment, mounting and installation. The right budget depends less on the number of panels alone and more on the appliances you want to run, how long you need backup and the quality of the installation.
What you are paying for
A proper quotation separates generation from storage. Panels produce energy during daylight; the inverter converts it for household loads; batteries store energy for evening use; and protection devices keep the system safe. Installation also covers cable sizing, earthing, changeover arrangements and commissioning.
How to estimate your system size
1. List essential loads
Record each appliance, its wattage and daily hours. Separate essentials such as lights, fans, a television, router, refrigerator and security devices from high-load appliances such as irons, kettles and water heaters.
2. Choose autonomy
One night of battery backup is a common starting point. More autonomy needs more usable battery capacity and a larger budget. Lithium batteries generally provide better usable capacity and cycle life than older lead-acid options, but the final choice should follow the duty cycle and service plan.
3. Confirm site conditions
Roof direction, shade, cable runs, ventilation and available mounting space affect the design. A professional survey prevents under-sizing and unsafe shortcuts.
How to compare quotations
Ask for model numbers, usable battery capacity, warranty terms, protection equipment, expected maintenance and commissioning tests. Do not compare two prices unless they include equivalent components and installation scope.
Frequently Asked Questions
Is the cheapest solar quote the best?
No. A low quote can exclude protection, installation labour, adequate battery capacity or after-sales support.
Can I start small?
Yes. A modular inverter and battery system can be designed for essential loads first, provided future expansion is considered.
