How much is a solar panel in Nigeria? Observed retail listings checked on 16 September 2026 range from about ₦20,000 for a 100 W panel to ₦200,000 for 650 W. Per watt, most Tier-1 monocrystalline panels land between ₦167 and ₦350; the common 450–550 W residential sizes sit at ₦211–300/W. Prices track the naira–dollar rate (CBN ₦1.326,3/$ on 14 September 2026) because nearly all panels are imported, duty-free and VAT zero-rated.
Prices by wattage
Ranges span budget to Tier-1 brands; the low end is usually a distributor brand or a cash-and-carry price in Lagos, the high end a branded panel with a verifiable warranty from a shop that delivers.
| Panel | Low | High | ₦ per watt | Range |
|---|---|---|---|---|
| 100 WSmall mono/poly, often unbranded | ₦20,000 | ₦35,000 | 200–350 | |
| 200 WMono; Felicity-class brands at the top | ₦34,000 | ₦65,000 | 170–325 | |
| 300 WOlder 60-cell formats | ₦50,000 | ₦85,000 | 167–283 | |
| 400 WJinko, Trina, Canadian Solar class | ₦90,000 | ₦120,000 | 225–300 | |
| 450 WCommon residential size | ₦95,000 | ₦130,000 | 211–289 | |
| 550 WMost common in new 5 kVA builds | ₦115,000 | ₦165,000 | 209–300 | |
| 600 WN-type/TOPCon appearing | ₦140,000 | ₦185,000 | 233–308 | |
| 650 WLarge-format; check roof span | ₦155,000 | ₦200,000 | 238–308 |
Price per watt is the number to compare
Two panels of different wattage cannot be compared on sticker price. Divide price by rated watts. In the current market, larger panels (450–650 W) are cheaper per watt than 100–300 W panels because they use the same frame, glass, junction box and shipping volume for more cells. A 100 W panel at ₦undefined–undefined/W costs up to NaN% more per watt than a 550 W panel at ₦undefined–undefined/W.
Per-watt cost also sets the ceiling on what an installer can fairly charge for an array: 10 × 550 W at ₦undefined–undefined/W is ₦1.15m–₦1.65m in panels alone. If a quotation's panel line is far above that, ask which brand and model, and check the datasheet.
Prices by brand
Tier-1 manufacturers (a Bloomberg NEF bankability list, not a quality certificate) dominate Nigerian imports. Prices below are for their 400 W-class and 550 W-class modules where listings exist.
| Brand | 400 W class | 550 W class | Notes |
|---|---|---|---|
| Jinko Solar | ₦95,000–115,000 | ₦125,000–150,000+ | Tier-1; widely stocked in Lagos |
| Canadian Solar | ₦100,000–115,000+ | ₦135,000–160,000+ | Tier-1 |
| LONGi | ₦100,000–125,000 | ₦135,000–175,000 | Tier-1; Hi-MO series |
| Trina Solar | ₦95,000–115,000 | ₦120,000–160,000+ | Tier-1; Vertex 550–580 W |
| Felicity Solar | ₦85,000–110,000 | — | Nigeria-focused distributor brand; local warranty desk |
Unbranded or relabelled panels sell below these ranges. The risk is not that they fail on day one but that their rated wattage is optimistic and their degradation faster; without a datasheet and a traceable manufacturer, a warranty is a promise from the shop, not the factory. ZEUS does not sell or install equipment and has no commercial relationship with any brand or retailer named on this page.
Panel technology: what the labels mean
| Type | Efficiency | Typical size | Where it fits |
|---|---|---|---|
| Monocrystalline PERC | 20–22% | 400–550 W, 108–144 half-cells | The default residential panel today; best value per watt. |
| N-type TOPCon | 22–23.5% | 550–650 W | Newer; lower degradation (about 0.4%/yr vs 0.55%) and better in heat. Slight premium. |
| Bifacial (glass–glass) | 21–23% front, plus 5–15% rear gain | 550–650 W | Gains only with a reflective surface below (white roof, gravel, elevated ground mount). Little benefit on a dark corrugated roof. |
| Polycrystalline | 15–17% | 100–330 W | Old stock; cheaper per panel, more expensive per watt and per square metre. Avoid for new roofs. |
| Flexible / thin film | 10–18% | 50–200 W | Curved surfaces, vehicles, boats. Short life on hot roofs. |
Monocrystalline vs polycrystalline is no longer a real choice: almost every panel above 400 W is mono. The live decision is PERC vs TOPCon (a few percent more output per square metre and slower ageing for a small premium) and whether bifacial gain is realistic on your mounting surface.
Temperature matters more than brochures admit. Rated watts are measured at 25 °C cell temperature. A roof-mounted panel in Lagos or Kano runs at 55–65 °C at midday; with a typical temperature coefficient of −0.34%/°C that is a 10–14% loss at peak. The Global Solar Atlas figures used below already include this.
What a panel really produces, by city
A 550 W panel does not make 550 W × 5 hours = 2.75 kWh a day. The Global Solar Atlas models a fixed, optimally tilted array with typical losses (temperature, soiling, wiring, inverter) and reports long-term yield per installed kilowatt-peak. Multiply by panel size to get daily energy.
| City | Yield, avg | Yield, worst month | 550 W panel, avg day | 550 W panel, worst month | Per year |
|---|---|---|---|---|---|
| Lagos | 3.63 kWh/kWp | 3.15 | 2.00 kWh | 1.73 kWh | 728 kWh |
| Ibadan | 3.65 kWh/kWp | 2.83 | 2.01 kWh | 1.56 kWh | 733 kWh |
| Port Harcourt | 3.43 kWh/kWp | 2.88 | 1.89 kWh | 1.58 kWh | 688 kWh |
| Enugu | 3.80 kWh/kWp | 3.20 | 2.09 kWh | 1.76 kWh | 762 kWh |
| Abuja | 4.13 kWh/kWp | 3.15 | 2.27 kWh | 1.73 kWh | 829 kWh |
| Kaduna | 4.45 kWh/kWp | 3.45 | 2.45 kWh | 1.90 kWh | 894 kWh |
| Kano | 4.65 kWh/kWp | 4.00 | 2.56 kWh | 2.20 kWh | 934 kWh |
The southern cities lose a quarter of their output from July to September (cloud, rain, Harmattan haze arrives later in the north). Any system that must carry the household through August in Lagos or Port Harcourt has to be sized on the worst month, not the annual mean. Full 14-city data: Nigeria solar resource by city.
How many panels does a home need?
Divide your daily energy use (kWh) by the worst-month yield for your city (kWh per kWp per day), add about 15% for battery charging losses, and divide by panel size in kW. A 12 kWh/day home in Lagos needs 12 ÷ 3.15 × 1.15 ≈ 4.4 kWp, which is 8 × 550 W panels. The same home in Kano needs 7.
PV_kWp = E_daily_kWh ÷ Yield_kWh_per_kWp_day ÷ η_batt
// η_batt ≈ 0.87 (LiFePO₄ round trip 0.92 × charge-path losses 0.95); use 0.80 for tubular
Panels = ceil(PV_kWp × 1000 ÷ Panel_W)
// Example, Lagos worst month
PV_kWp = 12 ÷ 3.15 ÷ 0.87 = 4.38 kWp → 8 × 550 W
| Daily use | Typical household | Lagos | Port Harcourt | Abuja | Kano |
|---|---|---|---|---|---|
| 4 kWh | Lights, fans, TV, phones, laptop | 3 | 3 | 3 | 3 |
| 8 kWh | + fridge and freezer all day | 6 | 6 | 6 | 5 |
| 12 kWh | + one 1 HP inverter AC, 6 h evening | 8 | 9 | 8 | 7 |
| 18 kWh | + second AC or pumping machine | 12 | 14 | 12 | 10 |
| 30 kWh | Large home, 2–3 ACs; small office | 20 | 22 | 20 | 16 |
Use the sizing calculator to enter your own appliance list, or the panel count calculator if you already know the array size.
Roof space and mounting
A 550 W panel is about 2.28 m × 1.13 m (2.6 m²). With walkways and edge clearance, allow about 3 m² per panel: ten panels need roughly 30 m² of unshaded roof facing south-ish or, in Nigeria's low latitudes, almost any direction at a shallow tilt. Optimum fixed tilt from the Global Solar Atlas is 7° in Lagos, 13° in Abuja and 16° in Kano; anything from 5° to 15° gives within a few percent of optimum, and 5° is the minimum for rain to wash off dust.
Corrugated aluminium and long-span roofs take standard rail-and-clamp mounting; concrete roofs use ballasted or bolted frames; older zinc sheets and rotten purlins need reinforcement before they take 20 kg per panel plus wind load. Ground mounts cost more in steel but make cleaning and bifacial gain easy.
Specifications that matter on the datasheet
| Line | Typical, 550 W mono | Why it matters |
|---|---|---|
| Pmax (STC) | 550 W | Rated power at 25 °C, 1000 W/m². Never reached on a hot roof. |
| Voc / Vmp | ≈ 49.5 V / 41.5 V | Sets how many panels a string can have inside the inverter's MPPT window. Voc rises in cool mornings. |
| Isc / Imp | ≈ 14 A / 13.3 A | Cable and fuse sizing; must sit under the MPPT's max input current. |
| Efficiency | 21–22% | Output per square metre; only matters when roof space is tight. |
| Temperature coefficient of Pmax | −0.34 %/°C (PERC), −0.30 (TOPCon) | Loss per degree above 25 °C. Lower is better in Nigeria. |
| Power warranty | ≥ 84.8% at 25 years (PERC), ≥ 87.4% at 30 (TOPCon) | Only enforceable through a manufacturer with a Nigerian channel. |
| Product warranty | 12–15 years | Covers defects, not output. |
| Certifications | IEC 61215, IEC 61730 | Design and safety tests. Ask to see them; relabelled panels often lack them. |
Buying checklist
- Compare per watt, not per panel. Divide price by rated watts; anything far outside ₦167–350/W needs a reason.
- Ask for the exact model number and download the datasheet from the manufacturer's site. "Jinko 550 W" is not a model.
- Check the label on the back of the panel matches the datasheet (model, Voc, Isc, serial) before it goes on the roof.
- Confirm who honours the warranty: a manufacturer-authorised distributor in Nigeria, or just the shop.
- Match string voltage to the inverter: total Voc of a string must stay under the MPPT maximum on a cool morning, and Vmp above its minimum on a hot afternoon. See MPPT input windows.
- Inspect for micro-cracks and snail trails on delivery; reject panels with cracked glass, delaminated edges or bent frames.
- Do not let panel count be set by the package. Size from your load audit and your city's worst month (above).
- Budget for mounting, cable, breakers and labour; see installation costs.
Solar arrays produce lethal DC voltages in daylight and cannot be switched off at the panel. Battery banks can deliver thousands of amps into a short circuit. Installation, wiring, earthing and commissioning must be done by a qualified installer or licensed electrician to the manufacturer's instructions and the Nigerian Electrical Installation Standards (IEC 60364-based). ZEUS explains how systems work so you can specify and check them, not so you can wire them yourself.
FAQ
How much is a 550 W solar panel in Nigeria?
Observed retail listings checked on 16 September 2026 put a 550 W monocrystalline panel at ₦115,000–₦165,000, about ₦undefined–undefined per watt depending on brand, warranty and seller. Delivery and mounting are extra.
How much is a 100 W solar panel?
About ₦20,000–₦35,000. Per watt that is expensive (₦undefined–undefined/W); small panels make sense only for small DC loads, not for house systems.
How many solar panels can power a 3-bedroom flat in Nigeria?
For a 12 kWh/day audit (fridge, freezer, fans, lights, TV, one inverter AC in the evening): about 8 × 550 W in Lagos or 7 in Kano, sized on the worst month with lithium storage. Without the AC, 8 kWh/day needs 6 panels in Lagos.
Which solar panel brand is best in Nigeria?
ZEUS does not rank brands. Jinko, LONGi, Trina and Canadian Solar are Tier-1 manufacturers with datasheets and certifications you can verify; Felicity is a distributor brand with a local warranty desk. What matters more than the name is the exact model, the temperature coefficient, the certifications and who will honour the warranty in Nigeria.
Is a monocrystalline panel better than polycrystalline?
Yes for any new installation: higher efficiency (20–22% vs 15–17%), lower price per watt today and less roof area per kW. Polycrystalline panels are old stock.
Why do solar panel prices change so often in Nigeria?
Panels are imported and priced in dollars; the naira moved from about ₦1,500/$ in 2024 to ₦1.326,3/$ (CBN, 14 September 2026). Duty is 0% and VAT is zero-rated, so the exchange rate and shipping dominate.
How long do solar panels last?
Manufacturers warrant about 85% of rated output after 25 years for PERC and 87% after 30 years for TOPCon. Real degradation in hot climates is 0.4–0.7% a year; the panel outlives two or three sets of batteries.
