How much does a solar photovoltaic panel cost for a household in Tunisia

As of March 2022, the price of electricity in Tunisia stood at $0.07 per kilowatt hour (kWh) for households, making it an affordable option for residential consumers. In contrast, businesses in Tunisia faced a slightly higher rate of $0.10 per kWh, reflecting the differing energy demands and usage patterns between the two sectors. 3

In other words, for every kilowatt-peak (kWp) of installed solar capacity, the system can generate approximately 1650 kilowatt-hours (kWh) of electricity per year. 2 As of March 2022, the price of electricity in Tunisia stood at $0.07 per kilowatt hour (kWh) for households, making it an affordable option for residential consumers.

Commercial solar installations are a great way for companies to lower energy costs. Generally, installing solar panels on businesses costs a bit less per watt because the systems are larger, but the total costs will be higher. In 2025, the average cost for commercial solar panels is just about $2.00 per watt.

The price of solar panels changes depending on where you live, but the average for installation is just under $29,000 or $2.75 per watt. On the high end, we talked to a solar customer in Hawaii who spent $100,000 going solar. Dion in Nevada said their 10-kW system cost about $20,000, which is about the national average price for a 7-kW system.

The cost of expanding a roof solar panel system depends largely on the number of solar panels. Typically, homeowners need to pay around $1000 for the installation (including plans and permits) and then around $500-$700 per new panel.

There is an average of 2993 hours of sunlight per year. 1 Tunisia boasts an impressive solar energy potential, with an average annual global horizontal irradiance (GHI) of approximately 1850 kWh/m². This abundant solar resource translates to an average annual energy production of solar photovoltaic (PV) systems of around 1650 kWh/kWp/yr.
