Compare grid bill relief, generator fuel savings, outage backup, battery choice, and quote-readiness using Algeria planning assumptions. Replace the defaults with your bill, fuel receipts, and installer quote before you buy.
This country page uses the same Solar ROI calculation engine as the main Africa calculator, preloaded with Algeria currency, tariff, fuel, solar yield, install cost, and battery assumptions.
Runs in your browser. No account is required. Inputs are planning estimates unless you choose to share or export them.
Use the same Algeria assumptions to compare common solar sizes. The highlighted row follows the selected system size above; edit inputs to update the table.

Solar payback in Algeria starts with grid bills, generator fuel, and outages. This page preloads DZD defaults: 4.7 DZD/kWh electricity, 46 DZD/litre fuel, DZD 50,000/kW install cost, DZD 50,000 battery-cost band, and 6.5 peak sun hours/day. Treat the output as a planning estimate, not a quote.
Before asking for a final price in Algeria, collect a recent bill or prepaid history, one fuel receipt if a generator is used, essential appliances, and real outage hours. The calculator starts at DZD 1,410 grid bill and DZD 828 generator spend. Ask the installer to verify pumps, freezers, AC units, medical fridges, and other surge loads.
At the Algeria default of 4.7 DZD/kWh, every solar kWh used on site offsets that tariff. Higher tariffs can improve payback; subsidized, fixed-charge heavy, or low daytime-use bills can stretch it. Sonelgaz tariff. Subsidized by hydrocarbon revenues. Schools, clinics, landlords, and SMEs should check whether commercial tariffs differ from residential tariffs.
Generator fuel can change ROI because backup power often costs more per useful kWh than grid energy. This page uses 46 DZD/litre as the Algeria fuel default and converts monthly generator spend into avoided litres and run-hours. Subsidized. If generator spend is high but payback still looks weak, test a battery-first essential-load quote.
Battery backup is not the same as total daily energy. Size it around appliances that must run during an outage: lights, fan, router, phones, POS terminal, fridge, freezer, medical fridge, pump controls, or a small workstation. This page uses DZD 50,000 as the Algeria essential-load battery-cost band. Essential-load battery band derived from the 3 kW system-cost seed. Replace with quoted usable-kWh battery pricing. Ask for usable kWh, depth of discharge, chemistry, warranty, inverter compatibility, and replacement assumptions.
These examples use Algeria planning defaults, not promises. Pick the closest bill, generator spend, and outage pattern, then edit calculator values.
Starter backup is usually enough if night load is kept small. Load: lights, fan, TV, router, phones, and a disciplined fridge plan.
Load this scenarioEssential-load battery sizing is the safer planning default. Load: fridge, lights, fans, TV, router, laptops, and daytime appliances.
Load this scenarioExtended backup may be justified when lost trading hours cost more than the battery. Load: POS, lights, fans, router, refrigeration, and trading-hour reliability.
Load this scenarioThis is a planning estimate, not a quote. Tariff, fuel price, battery price, install scope, performance ratio, and solar yield can move the result. The Algeria solar yield default is 6.5 peak sun hours/day and performance ratio is 0.78. Largest solar potential in Africa but underdeveloped.

Use your DZD monthly bill, generator spend, outage hours, system size, battery choice, and finance terms. This page starts with 4.7 DZD/kWh, 46 DZD/litre, DZD 50,000/kW, and 6.5 peak sun hours/day. Replace each value with local data.
Yes, if you run a petrol or diesel generator. Add monthly fuel spend in DZD or edit the 46 DZD/litre assumption. Generator savings can turn weak payback into a strong case for homes, shops, clinics, schools, churches, landlords, and SMEs.
Not always. A battery is mainly for backup and night-time essential loads, not cheaper solar by default. If outages affect stock, safety, medical refrigeration, trading hours, or night power, compare no-battery solar with an essential-load battery using the DZD 50,000 planning band.
Start with daily kWh, peak load, outage hours, and appliances that must run during a power cut. A small home may start around 1-2 kW, a family home around 3-5 kW, and a shop or clinic should check load, surge, refrigeration, and trading hours before choosing a size.
Quotes in DZD change with panel wattage, inverter brand, battery chemistry, usable capacity, protection devices, mounting, wiring distance, roof work, labour, warranty, maintenance, and finance charges. Treat DZD 50,000/kW install cost and the DZD 50,000 battery band as planning defaults, not a price list.
You can edit tariff, fuel price, solar yield, performance ratio, system size, install cost, battery cost, maintenance, deposit, interest, finance term, outage hours, and backup level. Use local bills, fuel receipts, and installer quotes when available.
No. Use this for early planning and quote comparison. PVWatts, PVGIS, Global Solar Atlas, and installer design tools can model location, roof angle, shading, inverter limits, cable runs, and production more precisely.
It is a planning estimate, not a quote. The Algeria dataset was last reviewed on Mar 1, 2026 and confidence is Medium. Accuracy improves with recent DZD bills, real fuel receipts, a load profile, local solar-yield data, current equipment quotes, and provider finance terms.
Use these only when they answer the next question in your solar decision. For background reading, start with the generator vs solar guide.
