Commercial solar payback in Făgăraș: 6.3 years
A self-consuming 100 kWp array on a commercial roof in Făgăraș typically pays back in about 6.3 years. That figure uses Făgăraș's specific yield of 1,128 kWh per kWp per year and a commercial tariff near €0.18/kWh, with 70% of generation used on site.
At that yield the array produces about 112,800 kWh a year and saves roughly €14,213 annually against an installed cost near €90,000. Over 25 years the net saving is around €265,325, while avoiding about 39.5 tonnes of CO₂ each year.
Făgăraș is in Brașov County, alongside Brașov, Săcele and Codlea. 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 × 1,128 kWh/kWp = 112,800 kWh of annual production on a representative warehouse or factory roof in Făgăraș. Apply 70% self-consumption against €0.18 per kWh and you get about €14,213 a year. Divide the €900/kWp installed cost (€90,000 for 100 kWp) by that saving and payback lands at 6.3 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 Făgăraș cannot beat roughly 6.3 years on these inputs, it is probably not a priority lead.
Făgăraș versus the rest of Romania
Relative to Romania as a whole, payback in Făgăraș is a little slower than the Romania average of 6.0 years, because Brașov County sits on the cooler side of the national irradiance band. Romania’s growing industrial base and solid southern irradiance make commercial rooftops — especially in the southern plains — strong candidates for solar prospecting.
That is why outreach in Făgăraș should open with the local number — 6.3 years and €14,213 a year on 100 kWp — not a national average that under- or over-sells the roof.
What actually changes payback on a Făgăraș roof
Yield is already baked into the 1,128 kWh/kWp zone for Brașov 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 €0.18/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 Făgăraș sites by savings instead of guessing from a map pin.
Frequently asked questions
What is the commercial solar payback in Făgăraș?
About 6.3 years for a self-consuming 100 kWp rooftop in Făgăraș. That uses 1,128 kWh/kWp of local yield and a tariff near €0.18/kWh, saving around €14,213 a year.
How much electricity does 100 kWp produce in Făgăraș?
Around 112,800 kWh a year. Multiply the 1,128 kWh/kWp specific yield for Brașov 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 Făgăraș better than nearby towns?
Payback is in the same band as Brașov, Săcele and Codlea because they share the Brașov County irradiance zone. The practical difference is the stock of large, unshaded commercial roofs — SolarScout lists those in Făgăraș with a pre-computed saving so you can compare sites, not just towns.
