Commercial solar payback in Gjirokastër: 5.5 years
A self-consuming 100 kWp array on a commercial roof in Gjirokastër typically pays back in about 5.5 years. That figure uses Gjirokastër's specific yield of 1,470 kWh per kWp per year and a commercial tariff near €0.16/kWh, with 70% of generation used on site.
At that yield the array produces about 147,000 kWh a year and saves roughly €16,464 annually against an installed cost near €90,000. Over 25 years the net saving is around €321,600, while avoiding about 51.5 tonnes of CO₂ each year.
Gjirokastër is in Gjirokastër County, alongside Tepelenë and Përmet. Those towns share the same irradiance zone, so payback is similar — the difference is which warehouses and factories still have empty roof. SolarScout lists them with a pre-computed business case rather than a generic "solar is cheap" pitch.

Start with 100 kWp × 1,470 kWh/kWp = 147,000 kWh of annual production on a representative warehouse or factory roof in Gjirokastër. Apply 70% self-consumption against €0.16 per kWh and you get about €16,464 a year. Divide the €900/kWp installed cost (€90,000 for 100 kWp) by that saving and payback lands at 5.5 years.
This is a worked example, not a quote. Real payback moves with self-consumption, shading, export tariff and installed cost. It is still the right first filter: if a roof in Gjirokastër cannot beat roughly 5.5 years on these inputs, it is probably not a priority lead.
Gjirokastër versus the rest of Albania
Relative to Albania as a whole, payback in Gjirokastër is about 0.2 years faster than the Albania average of 5.7 years. Albania has excellent Mediterranean sunshine. As its commercial and logistics sectors expand, factory and warehouse rooftops are an under-tapped solar opportunity.
That is why outreach in Gjirokastër should open with the local number — 5.5 years and €16,464 a year on 100 kWp — not a national average that under- or over-sells the roof.
What actually changes payback on a Gjirokastër roof
Yield is already baked into the 1,470 kWh/kWp zone for Gjirokastër County. The bigger swings are usable roof area, daytime load (factories and cold stores self-consume more than empty warehouses) and whether the site pays the full €0.16/kWh commercial rate.
SolarScout estimates roof footprint from satellite and map data and, where Google Solar coverage exists, modelled annual output — so you can rank Gjirokastër sites by savings instead of guessing from a map pin.
Frequently asked questions
What is the commercial solar payback in Gjirokastër?
About 5.5 years for a self-consuming 100 kWp rooftop in Gjirokastër. That uses 1,470 kWh/kWp of local yield and a tariff near €0.16/kWh, saving around €16,464 a year.
How much electricity does 100 kWp produce in Gjirokastër?
Around 147,000 kWh a year. Multiply the 1,470 kWh/kWp specific yield for Gjirokastër County by 100 kWp; shading and orientation can move that figure, which is why SolarScout models each roof rather than stopping at the city average.
Is payback in Gjirokastër better than nearby towns?
Payback is in the same band as Tepelenë and Përmet because they share the Gjirokastër County irradiance zone. The practical difference is the stock of large, unshaded commercial roofs — SolarScout lists those in Gjirokastër with a pre-computed saving so you can compare sites, not just towns.
