Commercial solar payback in Râmnicu Sărat: 5.8 years
A self-consuming 100 kWp array on a commercial roof in Râmnicu Sărat typically pays back in about 5.8 years. That figure uses Râmnicu Sărat's specific yield of 1,224 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 122,400 kWh a year and saves roughly €15,422 annually against an installed cost near €90,000. Over 25 years the net saving is around €295,550, while avoiding about 42.8 tonnes of CO₂ each year.
Râmnicu Sărat is in Buzău County, alongside Buzău, Nehoiu and Pătârlagele. 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 × 1,224 kWh/kWp = 122,400 kWh of annual production on a representative warehouse or factory roof in Râmnicu Sărat. Apply 70% self-consumption against €0.18 per kWh and you get about €15,422 a year. Divide the €900/kWp installed cost (€90,000 for 100 kWp) by that saving and payback lands at 5.8 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 Râmnicu Sărat cannot beat roughly 5.8 years on these inputs, it is probably not a priority lead.
Râmnicu Sărat versus the rest of Romania
Relative to Romania as a whole, payback in Râmnicu Sărat is about 0.2 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 Râmnicu Sărat should open with the local number — 5.8 years and €15,422 a year on 100 kWp — not a national average that under- or over-sells the roof.
What actually changes payback on a Râmnicu Sărat roof
Yield is already baked into the 1,224 kWh/kWp zone for Buzău 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 Râmnicu Sărat sites by savings instead of guessing from a map pin.
Frequently asked questions
What is the commercial solar payback in Râmnicu Sărat?
About 5.8 years for a self-consuming 100 kWp rooftop in Râmnicu Sărat. That uses 1,224 kWh/kWp of local yield and a tariff near €0.18/kWh, saving around €15,422 a year.
How much electricity does 100 kWp produce in Râmnicu Sărat?
Around 122,400 kWh a year. Multiply the 1,224 kWh/kWp specific yield for Buzău 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 Râmnicu Sărat better than nearby towns?
Payback is in the same band as Buzău, Nehoiu and Pătârlagele because they share the Buzău County irradiance zone. The practical difference is the stock of large, unshaded commercial roofs — SolarScout lists those in Râmnicu Sărat with a pre-computed saving so you can compare sites, not just towns.
