I took interest in your mail because my son is your name sake.
Anyway, solar panels are abundantly available in Nigeria for sale especially in Lagos.
From the content of your mail, I imagine that you probably have not quite decided how you would use these panels, and you probably do not have the slightest idea of what these size of solar panels will cost you. I bought a 75w panel about 5 years ago for about 50,000Naira.
I guess besides these panels you would need batteries and an inverter.
Best of luck.
