Solar Installation in Lekki: Prices, Eko Electricity Supply and How It Works

InfraSol installs solar and lithium battery systems for homes, apartment blocks and offices in Lekki: Phase 1, Oniru, Ikate, Agungi, Osapa, Chevron, Lekki Phase 2 and on to Ajah and Sangotedo, and next door in Ikoyi and Victoria Island. Below is what supply on Eko Electricity has looked like this year, the two systems we have running in Lekki, what each size costs, and how an installation runs.

Supply on Eko Electricity this year

Lekki has had three big outages since August. In early August a transformer blew in Lekki Phase 1 and residents around Alhaji Hakeem Odumosu Street went almost two weeks without light, buying fuel daily and throwing out spoiled food. On 1 September Eko Electricity said 12 feeders were down across Lekki, Ajah and Ibeju-Lekki, including Ikate Express, Chevron, Maroko, Ilasan and Oke-Ira. On 19 October the Ajah transmission substation lost supply, and the Ajah–Lekki 330kV line was not fully back until the afternoon of 21 October.

Band A in Lekki is not 20 hours a day. Band A customers pay the top tariff for a promise of at least 20 hours. A Band A feeder we monitor in Lekki Phase 1 has given about 14.5 hours a day on average, and in August, its worst month, about 10.8. Our Band A vs solar comparison works out what that costs once the generator is counted.

Our installs in Lekki

A 4-bedroom home. The family was running several ACs, a big fridge-freezer and the generator most evenings, and choosing which rooms got AC. We installed 10 kWp of Jinko 620W panels, an Aurora 11 kVA hybrid inverter and 20 kWh of lithium battery, bought outright for ₦8M. The whole house now runs on solar, ACs included, and the battery carries the night. Read the full write-up.

An office. It was running its generator 6 to 8 hours every working day for computers, network, a small server and AC. We installed 8.8 kWp of panels, an SRNE 10 kVA inverter and 15 kWh of battery for ₦6.5M. Energy costs fell by about 70%, and staff don’t notice when Eko goes off. Read the full write-up.

What solar costs in Lekki

These are our published installed prices for Lagos, Lekki included. A 1–2 bedroom flat in Oniru or Ikate running one AC starts at the 6kVA Lite, and a 2–3 bedroom flat is a 6kVA Pro or Max. A 3–4 bedroom duplex is a 10kVA, usually the Pro (the 4-bedroom home above runs on an 11kVA Aurora, the inverter in our 10kVA Lite and Pro), and a large 5-bedroom duplex running 4 or more ACs is a 20kVA. Offices, clinics and restaurants on Admiralty Way or Lekki–Epe Expressway now running a 20kVA generator take a 20kVA, and apartment blocks and estates take the 30 or 50kVA on the packages page.

You don’t have to pay it all at once. With lease to own, you pay 30–40% down, we install, and you pay the rest over 3, 6 or 12 months. The financing page lists the monthly payment for every size. Not sure which size you need? Start from your monthly diesel and Eko spend in the solar calculator.

Duplexes, terraces and apartment blocks

Duplexes and terraces are the simple case: the system goes on your own roof, and the inverter and battery go in a garage, store or utility room.

Flats share a roof. If the building has one owner or a landlord who agrees, one system sized for the whole block, with a central changeover, costs less per flat than each tenant buying their own, and it replaces the shared generator. If you are one tenant, we size a system for your flat on your share of the roof, or one that runs mostly from battery and charges from Eko and whatever panels fit.

Estate rules. Most Lekki estates want contractors approved by the estate office before work starts. Tell us your estate when you get in touch and we plan the install around its rules.

Keep your meter, add solar

Solar doesn’t replace your Eko connection. The hybrid inverter runs the house or office from the panels in the day, from the battery at night, and takes grid power when it comes, so you buy far fewer units and the generator stays off. When the feeder goes out, the inverter switches over on its own.

Buying panels only?

We sell genuine Jinko Tiger Neo 620W bifacial panels on their own: ₦134,000 each, or ₦130,000 each by the pallet of 36. Every panel has a serial number you can check with Jinko, and delivery anywhere in Lagos is within 48 hours. See the Jinko 620W panel page.

How an installation works

1. Tell us what you run. Your appliances, your street or estate in Lekki, and what diesel and Eko cost you each month, on WhatsApp or the contact page.
2. Site survey. An engineer measures your real load and your roof, so the system is sized for your building, not guessed from the inverter size.
3. Written quote. A fixed price that names the panel brand and wattage, the battery size in kWh and the inverter model.
4. Install and monitor. We install, commission and hand over the monitoring app, and our engineers watch the same data.

How to choose a solar installer in Lekki

• They survey your load and roof before they quote, instead of pricing from the inverter size.
• The quote names the panel brand and wattage, the battery chemistry and size in kWh, and the inverter model.
• Ask what the mounting rails and bolts are made of. Lekki is by the lagoon and the sea, and plain steel rusts in the salty air; anodised aluminium rails and stainless steel bolts last.
• The inverter and battery should go on the wall or a stand, off the floor, in a ventilated room. Many Lekki streets flood in heavy rain.
• They show serial numbers you can check with the manufacturer. Fake and refurbished panels are common in Lagos markets.
• They can show you systems they have actually installed, with photos and monitoring, not stock images.
