Dakar residential solar: an exploding market in 2026
The Senegal residential solar market explodes between 2022 and 2026. Drivers: rising Sénélec cost (+25% in 4 years), frequent outages, cheaper Chinese panels (Trina, Jinko, Longi), Sénélec authorizes self-consumption since 2024, ecology awareness.
Annual Dakar residential solar market: ~8-15 billion FCFA in 2026, growing +35-45%/year.
SolarPro Dakar, founded 2021, contacted me in May 2024. 48 installations/year. Fourteen months later: 180 installations/year (×3.75). Here is the mechanism.
H2: Site + calculator + financing
Site with sizing calculator (enter: villa surface, monthly Sénélec bills, equipment). Instantly generates: recommended power (kWp), panel count, total cost, annual savings, ROI years.
2026 standard configurations.
- 3-bedroom villa: 4-6 kWp, 12-18 450W panels. Cost 4.5-7.8 M FCFA. Savings 480-780 KFCFA/year. ROI 7-10 years.
- 5-bedroom villa: 6-10 kWp, 18-32 panels. Cost 7.5-15 M FCFA. Savings 850 KFCFA-1.5 M/year. ROI 7-9 years.
- Large villa + pool: 10-18 kWp, 32-60 panels. Cost 15-32 M FCFA. Savings 1.5-3 M/year. ROI 7-10 years.
Financing. Cash payment 5% discount, or 3-5 year installments 0% interest (subsidized by battery supplier). Bank credit (BNDE green energy program, rates 6-9%).

| Site + calculator | 5,500,000 to 9,000,000 FCFA | 280,000 FCFA |
| Brand book + certifications | 1,800,000 FCFA | — |
| Panel + inverter + battery stock | 65,000,000 FCFA initial | 38,000,000 FCFA restock |
| 8 certified installer technicians | 800,000 FCFA recruitment | 4,500,000 to 6,500,000 FCFA |

Upfront investment: 101-105 M FCFA. Monthly recurring: 49-54 M FCFA. For 180 installations × 8.5 M FCFA average basket = 1.53 billion FCFA / year. Net margin 18-25% = 275-380 M FCFA / year.
