Commercial solar payback in Corabia: 5.6 years
A self-consuming 100 kWp array on a commercial roof in Corabia typically pays back in about 5.6 years. That figure uses Corabia's specific yield of 1,284 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 128,400 kWh a year and saves roughly €16,178 annually against an installed cost near €90,000. Over 25 years the net saving is around €314,450, while avoiding about 44.9 tonnes of CO₂ each year.
Corabia is in Olt County, alongside Slatina, Caracal and Balș. 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 × 1,284 kWh/kWp = 128,400 kWh of annual production on a representative warehouse or factory roof in Corabia. Apply 70% self-consumption against €0.18 per kWh and you get about €16,178 a year. Divide the €900/kWp installed cost (€90,000 for 100 kWp) by that saving and payback lands at 5.6 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 Corabia cannot beat roughly 5.6 years on these inputs, it is probably not a priority lead.
Corabia versus the rest of Romania
Relative to Romania as a whole, payback in Corabia is about 0.4 years faster than the Romania average of 6.0 years. 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 Corabia should open with the local number — 5.6 years and €16,178 a year on 100 kWp — not a national average that under- or over-sells the roof.
What actually changes payback on a Corabia roof
Yield is already baked into the 1,284 kWh/kWp zone for Olt 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 Corabia sites by savings instead of guessing from a map pin.
Frequently asked questions
What is the commercial solar payback in Corabia?
About 5.6 years for a self-consuming 100 kWp rooftop in Corabia. That uses 1,284 kWh/kWp of local yield and a tariff near €0.18/kWh, saving around €16,178 a year.
How much electricity does 100 kWp produce in Corabia?
Around 128,400 kWh a year. Multiply the 1,284 kWh/kWp specific yield for Olt 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 Corabia better than nearby towns?
Payback is in the same band as Slatina, Caracal and Balș because they share the Olt County irradiance zone. The practical difference is the stock of large, unshaded commercial roofs — SolarScout lists those in Corabia with a pre-computed saving so you can compare sites, not just towns.
