Wetin separate good installer from cheap quote
The cheapest quote almost always dey save money for the places wey you no fit see: cable wey too small, no correct earthing, no surge protection, cheap breaker, and panel wey dem mount for way wey storm go carry. None of that go show for the day wey dem commission am. E go show for year two, when something spoil and the warranty talk go reveal say the installer no dey trade again.
Ask for wiring diagram and the specification of the wiring and protection — cable size, breaker rating, earthing arrangement, mounting method — no be only panel, inverter and battery. Installer wey dey give you that as normal thing dey tell you something about how dem dey work. The one wey go find the request strange dey tell you something too.
Warranty only good as the company wey dey behind am
Twenty-five year panel warranty and ten-year inverter warranty na standard for paper. For real life, warranty na promise from one particular company say e go still dey exist and still dey process claim years from now, and Lagos solar don see plenty installer wey no last. Company age, physical address wey you fit visit, and installation wey you fit go look, worth pass the length of warranty wey dem print for the quote.
Separate the equipment warranty from the workmanship warranty too. Manufacturer dey cover the panel; installer dey cover the installation. Ask clear clear how long dem dey cover the workmanship and wetin e include, because na that warranty you go most likely need, and na am dem dey most often leave vague.
As benchmark: labour and wiring dey usually run 10–20% on top of component cost for Lagos (Triangulated Lagos installer quotes, verify 2026-07-13). Quote wey far below that band usually dey cut the wiring and protection, no be say the person efficient.
Installed tier price, so you fit judge whether quote reasonable.
