Commercial solar payback in Marghita: 6.0 years
A self-consuming 100 kWp array on a commercial roof in Marghita typically pays back in about 6.0 years. That figure uses Marghita's specific yield of 1,188 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 118,800 kWh a year and saves roughly €14,969 annually against an installed cost near €90,000. Over 25 years the net saving is around €284,225, while avoiding about 41.6 tonnes of CO₂ each year.
Marghita is in Bihor County, alongside Oradea, Salonta and Beiuș. 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 × 1,188 kWh/kWp = 118,800 kWh of annual production on a representative warehouse or factory roof in Marghita. Apply 70% self-consumption against €0.18 per kWh and you get about €14,969 a year. Divide the €900/kWp installed cost (€90,000 for 100 kWp) by that saving and payback lands at 6.0 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 Marghita cannot beat roughly 6.0 years on these inputs, it is probably not a priority lead.
Marghita versus the rest of Romania
Relative to Romania as a whole, payback in Marghita is about 0.0 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 Marghita should open with the local number — 6.0 years and €14,969 a year on 100 kWp — not a national average that under- or over-sells the roof.
What actually changes payback on a Marghita roof
Yield is already baked into the 1,188 kWh/kWp zone for Bihor 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 Marghita sites by savings instead of guessing from a map pin.
Frequently asked questions
What is the commercial solar payback in Marghita?
About 6.0 years for a self-consuming 100 kWp rooftop in Marghita. That uses 1,188 kWh/kWp of local yield and a tariff near €0.18/kWh, saving around €14,969 a year.
How much electricity does 100 kWp produce in Marghita?
Around 118,800 kWh a year. Multiply the 1,188 kWh/kWp specific yield for Bihor 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 Marghita better than nearby towns?
Payback is in the same band as Oradea, Salonta and Beiuș because they share the Bihor County irradiance zone. The practical difference is the stock of large, unshaded commercial roofs — SolarScout lists those in Marghita with a pre-computed saving so you can compare sites, not just towns.
