The five-bedroom bungalow located in Ejigbo, was built and managed by Concept Technologies, the Guardian reported.
According to the company’s managing director, Tokunbo Tonade, the idea of the house was initiated from the need to use renewable energy to solve the country’s erratic power supply.
Off-grid solar house
Tonade said: “The home is a 5 bedroom bungalow powered by a 12.6kW solar off-grid system that runs 94% on the power of the sun and 6% on diesel during cloudy weather.
He noted: “Off-grid means it has been completely disconnected from thermal electricity, and it’s been running without a blink since the last one year.”
Tonade further explained that the solar system generates 12.6kW of electricity per hour using 63 units of 200W solar modules, three units of 60AMPS MPPT controllers, three units of 3.2kW inverters and 24 units of 200AMPD deep cycle batteries.
“I have been trying to advocate for renewable energy because it has a lot of gains and for Nigerians to see its impact. With generator, you use some amount of money to install the generator, buy diesel and fuel it yearly and when we add everything up, they are higher than what you will use to install solar energy,” he added.
Solar off-grid system for banking industry
Tonade also encouraged banks to adopt the solar off grid system to power their branches. Read more…
He said in the long-run, every year a bank spends N50 million ($138,373) to power each of its branches, in 10 years, it would have spent N500 million ($1,3 million) to power a branch alone.
“I want to give you something that has 25 years warranty at N120 million ($332,436), and it will break even in two years, unlike your generator where you are spending N500 million in 10 years and you are still spending all the way.”
