Commercial solar payback in Luduș: 6.2 years
A self-consuming 100 kWp array on a commercial roof in Luduș typically pays back in about 6.2 years. That figure uses Luduș's specific yield of 1,152 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 115,200 kWh a year and saves roughly €14,515 annually against an installed cost near €90,000. Over 25 years the net saving is around €272,875, while avoiding about 40.3 tonnes of CO₂ each year.
Luduș is in Mureș County, alongside Târgu Mureș, Reghin and Sighișoara. 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 × 1,152 kWh/kWp = 115,200 kWh of annual production on a representative warehouse or factory roof in Luduș. Apply 70% self-consumption against €0.18 per kWh and you get about €14,515 a year. Divide the €900/kWp installed cost (€90,000 for 100 kWp) by that saving and payback lands at 6.2 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 Luduș cannot beat roughly 6.2 years on these inputs, it is probably not a priority lead.
Luduș versus the rest of Romania
Relative to Romania as a whole, payback in Luduș is a little slower than the Romania average of 6.0 years, because Mureș 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 Luduș should open with the local number — 6.2 years and €14,515 a year on 100 kWp — not a national average that under- or over-sells the roof.
What actually changes payback on a Luduș roof
Yield is already baked into the 1,152 kWh/kWp zone for Mureș 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 Luduș sites by savings instead of guessing from a map pin.
Frequently asked questions
What is the commercial solar payback in Luduș?
About 6.2 years for a self-consuming 100 kWp rooftop in Luduș. That uses 1,152 kWh/kWp of local yield and a tariff near €0.18/kWh, saving around €14,515 a year.
How much electricity does 100 kWp produce in Luduș?
Around 115,200 kWh a year. Multiply the 1,152 kWh/kWp specific yield for Mureș 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 Luduș better than nearby towns?
Payback is in the same band as Târgu Mureș, Reghin and Sighișoara because they share the Mureș County irradiance zone. The practical difference is the stock of large, unshaded commercial roofs — SolarScout lists those in Luduș with a pre-computed saving so you can compare sites, not just towns.
