Frequent grid collapse and rising electricity bills are driving a revolution in Nigeria’s housing sector. With over 85 million people lacking access to electricity, developers are turning to solar power to fill in the gap—creating entire residential estates that can function completely off-grid.
Across Lagos and Abuja, real-estate entrepreneurs are pioneering solar-driven micro-estates, typically comprising 50-200 units. These communities integrate with solar roofs alongside inverters and batteries to deliver uninterrupted electricity.
While clean energy is fast becoming a marketing advantage for developers, it’s also setting the stage for a sustainable housing model that could reshape Nigeria’s urban future.
Among the trailblazers is the Citadel View Estate in Ajah, Lagos, which is the first solar-powered residential estate in Nigeria.
It provides duplexes and apartments with access to 24-hour electricity and other amenities.
In Abuja, Sun City Green and Smart Estate in Karshi are redefining urban living through clean energy, smart home systems and sustainable materials.
For Engineer Ebube Nwankwo, who helped in the solar installation at Sun City, the experience was transformative.
“I used to think housing development was only about cement and bricks,” he says, standing under the shade of a gleaming rooftop panel. “But when you wire an estate to run purely on solar, no diesel, no PHCN, you begin to see the future. Every time I flip a switch here and the lights come on, I know we’re changing how people live.”
Each home in the estate features 10-15 solar panels, hybrid inverters and lithium batteries connected to a smart load management system to balance the usage among the houses.
“The total output can provide 250 kilowatts of clean energy,” Ebube explains. This can power fans, light bulbs, fridges, as well as air conditioning units all day and all night. This shows that living off the grid can surely happen in the city,”
Solar energy to the rescue
The appeal of solar-powered estates lies in its reliability and cost efficiency. In Nigeria’s cities, where the grid can go down several times in one day, the assurance of perpetual electricity can command a higher price.
A 3-bedroom terrace in a fully solar estate in Lagos sells for about ₦98 million, compared with ₦88 million for a similar non-solar home.
Despite the investment required, the returns are fruitful. Energy experts say that households in solar estates are able to cut their electricity bills by 50-70%.
“One of my clients once told me he hasn’t bought fuel for the last three months,” Ebube laughs. “His generator just looks like an ornament. This is the kind of thing that makes doing this job worth the effort.”
These estates rely on the interconnectivity between photovoltaic panels, inverters, battery storage and smart meters to manage consumption.
Research shows that solar PV systems can deliver 25–40% energy savings for urban buildings in Nigeria, achieving payback within six to eight years.
The shift from individual rooftop installations to estate-scale microgrids also helps reduce cost per home.
“When you centralise power systems for 50 or 100 houses, you cut the cost of wiring, maintenance and inverter units,” Ebube explains. “It’s cooperative energy in action.”
Counting the cost
The price differential between solar and conventional homes can look steep, but context matters. Installing a household solar system (5–10 kVA) typically costs between ₦1.2 million and ₦4 million, depending on capacity and battery size
In solar-powered estates, however, this cost factor is reflected in the price of the house, effectively turning energy independence into a long-term investment rather than a luxury.
“People ask if it’s expensive,” Ebube goes on. “But when you calculate how much money the average family can spend in five years on diesel fuel, maintaining generators, and electricity bills, solar power is way cheaper.”
Sustainability
Lagos leads Nigeria’s solar-powered estates, but other states like Nasarawa and Ogun are following suit.
Under the federal Solar Power Naija programme, the Rural Electrification Agency has partnered with the Nasarawa State Government to deploy solar mini-grids in underserved communities like Amusha and Toto, expanding affordable energy access.
In Ogun State, the Smart Green City Project near Sagamu aims to build a 100% clean-energy housing development powered by mini-grids, creating a sustainable model for middle-class residents.
“We see the momentum,” says Ebube. “If the states develop policies to promote this model, Nigeria can save billions of dollars in energy expenses and generate job opportunities in solar power installation, battery maintenance, and data management services.”
Obstacles still ahead
Despite the optimism, access to funding remains a major hurdle, as many banks still classify solar estates as high-risk investments.
Maintenance is another concern—solar batteries need replacement every five to fifteen years, and poorly maintained panels lose efficiency.
“Solar is not a one-time investment; you have to care for it like a living system,” Ebube says. “If a panel cracks or a battery swells, it affects performance, so regular checks are always needed.”
The road ahead
Creating a sustainable future for solar housing estates in Nigeria, experts emphasise, requires three key priorities. Firstly, access to long-term financing via green loans and guarantees needs to be expanded to allow developers to expand projects and make solar homes more affordable.
Also, technical training and certification programmes in renewable energy have to be scaled up to produce competent engineers and installers who will maintain the systems on site.
Public-private partnership models engaged within governments and private energy companies can help spur innovation, cost reduction of the system, and long-term maintenance support.
“Nigeria doesn’t need to wait for a perfect grid to achieve stable power,” says Ebube. “We can build stability from the ground up, estate by estate, roof by roof.”
As Nigeria’s cities expand, solar estates offer a glimpse of a future where housing and energy coexist sustainably—where the power derives from the orange sun shining above the rooftops.
