Enter your monthly Sonelgaz bill and wilaya — get solar system size, self-consumption savings in DZD, FNERC off-grid subsidy, Saharan diesel replacement economics, and payback period.

DZD (دج)
Solar system results — Algeria
5 kWp system — 1460 kWh/kWp/yr (5 PSH)
Monthly kWh usage667 kWh/mo
Annual solar production7 300 kWh/yr
Self-consumption savings15 330 DZD/yr
Total annual benefit15 330 DZD/yr
Sonelgaz blended rate used6 DZD/kWh (DZD 4–9 tiered)
FNERC subsidyNo

Total installed cost (midpoint)925 000 DZD
Grid payback long (12–18yr) due to subsidized Sonelgaz rates60.3 years
25-year net savings-541 750 DZD
Note on grid payback: Algeria's highly subsidized Sonelgaz electricity (DZD 4–9/kWh, ~$0.03–0.07) makes grid-tied payback challenging at 12–18 years. Off-grid southern systems replacing diesel generators (DZD 55+/kWh true cost) achieve 3–5 year payback — far more compelling economics.

How to Use This Calculator

Enter your monthly bill and wilaya

Enter your average monthly Sonelgaz electricity bill in Algerian Dinars (DZD). Algeria's tiered grid tariff ranges from approximately DZD 4/kWh for the lowest consumption bracket to DZD 9/kWh for higher consumption — the calculator uses DZD 6/kWh as a blended average. For off-grid desert scenarios where grid electricity is unavailable, enter 0. Select your wilaya — Tamanrasset (6.5 PSH) in the Sahara is the sunniest location in Algeria and one of the highest solar irradiance sites on Earth.

System size and FNERC subsidy

Select your system size in kWp. Algeria has no formal net metering policy for grid-tied systems, so the economics are based on self-consumption savings. For off-grid applications in southern Algeria, the FNERC (Fonds National des Energies Renouvelables et de Cogénération) supports rural electrification programs that can reduce system cost by approximately 20% for eligible households in remote Saharan communities.

Off-grid vs. grid-tied in Algeria

The economic case for solar is fundamentally different between northern Algeria (grid-tied) and southern Algeria (off-grid). In the north, ultra-low subsidized grid prices make grid-tied payback long at 12–18 years. In the south, replacing diesel generators at DZD 55+ per kWh true cost with abundant Saharan solar makes payback 3–5 years — one of the most compelling solar economics in the world.

The Formula

Monthly kWh = Monthly Bill ÷ DZD 6/kWh (blended Sonelgaz rate) Annual production = kWp × PSH × 365 × 0.80 efficiency Self-consumption = Annual kWh × 35% (grid-tied without battery) Self-consumption savings = Self-consumed kWh × DZD 6/kWh Off-grid diesel savings = Annual kWh × DZD 55/kWh (diesel true cost) System cost = kWp × DZD 150,000–220,000/kWp (~$1,100–1,650/kWp) FNERC rural subsidy = 20% cost reduction for eligible off-grid installations Payback = Total cost ÷ Annual benefit

Algeria's Programme National des Energies Renouvelables (PNER) targets 22 GW of solar by 2030, one of Africa's most ambitious programs. Sonelgaz, the national electricity utility, maintains some of the world's lowest grid tariffs due to extensive hydrocarbon subsidies — a key factor in evaluating grid-tied solar economics. The vast Saharan south, particularly the Ahaggar and Tassili regions around Tamanrasset, receives over 3,000 hours of sunshine annually.

Example

Karim — Tamanrasset desert off-grid, 8kWp replacing diesel

Karim runs a remote agricultural station near Tamanrasset. His diesel generator costs approximately DZD 55/kWh. He installs an 8kWp system with FNERC rural support.

ScenarioOff-grid diesel replacement
Wilaya / PSHTamanrasset, 6.5 PSH
System size8 kWp
FNERC subsidyYes — ~20% reduction

Result

Annual production~15,184 kWh/yr
Production per kWp~1,898 kWh/kWp/yr
Diesel savings~835,120 DZD/yr
System cost (with subsidy)~1,120,000–1,632,000 DZD
Payback~1.6–2.0 years
25-year net savings~18,500,000 DZD

Tamanrasset's extraordinary 6.5 PSH produces nearly 1,900 kWh/kWp/yr — among the highest in the world. Replacing diesel at the true economic cost makes this one of the most financially compelling off-grid solar scenarios globally. FNERC support makes the upfront investment accessible for rural Saharan communities.

FAQ

It depends strongly on location and use case. In northern Algeria (Algiers, Oran, Constantine), ultra-subsidized Sonelgaz grid prices of DZD 4–9/kWh make grid-tied payback long at 12–18 years. However, in southern Algeria (Tamanrasset, Adrar, Ouargla), replacing diesel generators with solar at the Sahara's extraordinary 6.0–6.5 PSH makes payback 3–5 years or less — outstanding economics. Algeria's 2030 target of 22 GW of renewables signals strong long-term policy support.
Algeria does not yet have a formal net metering or feed-in tariff scheme for residential solar. The regulatory framework for grid-tied prosumers is still being developed. As of 2026, grid-tied solar economics rely entirely on self-consumption savings, not export credits. This is why maximizing self-consumption (using power when the sun shines, adding batteries) is critical for northern Algerian grid-tied systems. Policy changes may improve economics in coming years.
FNERC (Fonds National des Energies Renouvelables et de Cogénération) is Algeria's national fund for renewable energy. It primarily supports rural off-grid electrification in the Saharan south, where grid extension is prohibitively expensive. FNERC-funded programs provide solar home systems and small village microgrids, with subsidies that can reduce costs by 20% or more for eligible rural communities. Contact Sonelgaz or the Ministry of Energy for current program eligibility.
Tamanrasset (6.5 PSH) and Adrar (6.3 PSH) in the deep Sahara receive extraordinary solar radiation — among the highest in the world. Ouargla (6.0 PSH) and Oran (5.4 PSH) are also excellent. Northern coastal cities like Algiers (5.0 PSH) and Constantine (4.9 PSH) receive good solar resources, still well above European averages. Algeria's entire territory enjoys exceptional solar potential.
Installed solar system costs in Algeria range from approximately DZD 150,000 to DZD 220,000 per kWp (roughly $1,100–1,650/kWp USD), comparable to regional markets. A typical 5kWp home system costs DZD 750,000–1,100,000. Equipment is imported and priced in hard currency, making DZD costs sensitive to exchange rate fluctuations. FNERC rural subsidies can reduce costs by ~20% for eligible off-grid installations in southern Algeria.
