Quick answer: A reliable solar installer in Lagos should offer a documented site survey, load assessment, engineered design, safe installation, commissioning records and after-sales support. A polished sales presentation alone is not enough to judge technical capability.
What a professional process looks like
Site survey
The installer should inspect loads, roof or ground conditions, shade, cable routes, earthing, ventilation and the location of batteries and inverter equipment.
Written design
Request a schedule showing panel capacity, inverter model, usable battery capacity, protection equipment, expected critical loads and expansion assumptions.
Safe installation
Good workmanship includes correct polarity, cable sizing, isolation, earthing, surge protection, labelling and neat separation of power and communication cables.
Commissioning
The team should demonstrate operating modes, record settings, explain monitoring and provide warranty and maintenance information.
Questions to ask before signing
Ask who will support faults, which warranties are local, what is excluded from the price and how the system will be maintained. Compare like-for-like scopes.
Frequently Asked Questions
Should I choose an installer by price?
Price matters, but it should be compared with the equipment, protection, workmanship and support included.
Does every Lagos home need the same system?
No. Occupancy, appliances, roof conditions and backup expectations vary significantly.
