☀️ Peak sun hours in Tunisia
Tunisia is sunny, especially inland and south — roughly 5 to 5.8 peak sun hours. The Sahara edge is highest; the northern coast a little lower.
| Region | Approx. peak sun hours (annual avg) |
|---|---|
| Southern Tunisia (Tozeur, Gabès) | ~5.5 – 5.9 |
| Central (Kairouan, Sfax) | ~5.2 – 5.7 |
| Greater Tunis & north coast | ~4.9 – 5.4 |

⚡ Electricity prices in Tunisia
Electricity from STEG is billed in rising tiers, with higher-consumption households paying noticeably more per kWh as subsidies are gradually reformed. Homes in the upper tiers benefit most from self-generation, since solar shaves off the most expensive units first.
💸 Incentives & net metering
Tunisia's Prosol programme has supported residential solar for years with subsidies and STEG-facilitated loans repaid via the electricity bill, alongside a net-metering arrangement for self-consumption with STEG. Terms evolve, so confirm the current Prosol subsidy and net-metering rules with STEG or an accredited installer before sizing.
💰 System cost & payback in Tunisia
Grid-tied self-consumption is common; rough guide:
| System size | Approx. cost | Suits |
|---|---|---|
| 2 kW | ~$1,800 – 3,000 | Small home |
| 3 kW | ~$2,500 – 4,200 | Typical home |
| 5 kW | ~$4,000 – 6,800 | Larger home / higher tier |

💡 Local insight: Tunisia
Tunisia stands out in North Africa for having a real, established residential solar pathway: the Prosol programme plus STEG net metering means a grid-connected home can install solar with recognised support and offset its bill rather than fighting the system. As electricity subsidies are slowly reformed and upper-tier tariffs rise, the payback for higher-consumption households keeps improving. Sizing to your STEG tariff tier is the smart move.
