Man mentions cost of 7.5kVA solar inverter
In the post, he mentioned that his first neighbour used a total of 53kWh and paid him ₦10,600 at the rate of ₦200/kWh.
@ciphertoone said his second neighbour used 45kWh and was charged a sum of ₦9,000, with a little extra added later.
He spoke about his third neighbour as well in the post, while mentioning the exact amount he had made in a month after selling solar power to his neighbours.
His statement:
"It's one month now and I've made 25k naira selling SOLAR light to my neighbours. Using a 10kW LiPO4 battery and 7.5kVA inverter with 8 x 650W panels.
"The first neighbour (N1) used 53kWh, that's 10,600 at the rate of 200/kWh.
"The second neighbour used 45kWh, which is 9k (he was added 5 days after N1).
"The last neighbour was added about 2 weeks after N1 and used 29.3kWh. So on a new month slate, the total speculated to make is 50k."

Speaking with Legit.ng about his decision to invest in a larger solar system, the young man explained that the idea started with a much smaller setup while he was a student.
He said he initially installed a 1.1kVA system to provide about 18 hours of electricity daily. However, he noticed that the battery was often fully charged by 10am, leaving some of the generated energy unused.
According to him, that observation inspired the idea behind his company, T&S Power Grid, and eventually led him to develop a system that allows surplus solar power to be shared with neighbours.
He explained:
“I actually started with a small 1.1kVA system — just enough to give myself about 18 hours of light a day as a student. But I noticed something: most mornings by 10am, the battery was already full and the rest of the energy just went to waste."
“That observation became the seed for my company, T&S Power Grid. I realised that if I was wasting surplus power, thousands of other solar owners across Lagos were doing the same thing."
“So the 7.5kVA system wasn't just a personal upgrade — it was built specifically to test the Gateway Hub, our device that automates metering, billing, and power sharing between neighbours. The bigger system was always about proving the concept.”
Speaking further about the experience of selling electricity to his neighbours, he said the process had been smooth because the Gateway Hub automatically manages key aspects of the service.
He explained that each neighbour has a smart meter, allowing them to monitor their electricity usage and wallet balance in real time, while he can also control the amount of current supplied to each user.
He said:
“Selling power through the Gateway Hub has been seamless. Each neighbour has a smart meter, and everything — usage tracking, wallet balances, disconnection and reconnection — is handled automatically."
“The neighbours can monitor their own consumption and balance in real time, while I can set maximum current limits per neighbour to protect my inverter from surge damage."
“The only real challenge is demand: I've had more neighbours declare interest than I can serve. With my current setup, I can only comfortably supply three neighbours while keeping enough power for my own household. That's a good problem to have, but it does mean I've had to turn people away.”

Meanwhile, Legit.ng recently reported that a man who purchased a 5kWh lithium solar system on instalments shared his experience after using it for 10 months.
The man revealed that the solar setup, valued at about $1,800, allowed him to go completely off the commercial electricity grid and enjoy an uninterrupted power supply. He added that he had consumed over 1,700 kWh of electricity from the system during the period and was saving money that would have otherwise been spent on electricity bills.
