Commercial solar payback in Ovidiu: 5.4 years
A self-consuming 100 kWp array on a commercial roof in Ovidiu typically pays back in about 5.4 years. That figure uses Ovidiu's specific yield of 1,320 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 132,000 kWh a year and saves roughly €16,632 annually against an installed cost near €90,000. Over 25 years the net saving is around €325,800, while avoiding about 46.2 tonnes of CO₂ each year.
Ovidiu is in Constanța County, alongside Constanța, Medgidia and Mangalia. 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 × 1,320 kWh/kWp = 132,000 kWh of annual production on a representative warehouse or factory roof in Ovidiu. Apply 70% self-consumption against €0.18 per kWh and you get about €16,632 a year. Divide the €900/kWp installed cost (€90,000 for 100 kWp) by that saving and payback lands at 5.4 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 Ovidiu cannot beat roughly 5.4 years on these inputs, it is probably not a priority lead.
Ovidiu versus the rest of Romania
Relative to Romania as a whole, payback in Ovidiu is about 0.6 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 Ovidiu should open with the local number — 5.4 years and €16,632 a year on 100 kWp — not a national average that under- or over-sells the roof.
What actually changes payback on a Ovidiu roof
Yield is already baked into the 1,320 kWh/kWp zone for Constanța 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 Ovidiu sites by savings instead of guessing from a map pin.
Frequently asked questions
What is the commercial solar payback in Ovidiu?
About 5.4 years for a self-consuming 100 kWp rooftop in Ovidiu. That uses 1,320 kWh/kWp of local yield and a tariff near €0.18/kWh, saving around €16,632 a year.
How much electricity does 100 kWp produce in Ovidiu?
Around 132,000 kWh a year. Multiply the 1,320 kWh/kWp specific yield for Constanța 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 Ovidiu better than nearby towns?
Payback is in the same band as Constanța, Medgidia and Mangalia because they share the Constanța County irradiance zone. The practical difference is the stock of large, unshaded commercial roofs — SolarScout lists those in Ovidiu with a pre-computed saving so you can compare sites, not just towns.
