Commercial solar payback in Badajoz: 3.4 years
A self-consuming 100 kWp array on a commercial roof in Badajoz typically pays back in about 3.4 years. That figure uses Badajoz's specific yield of 1,721 kWh per kWp per year and a commercial tariff near €0.22/kWh, with 70% of generation used on site.
At that yield the array produces about 172,100 kWh a year and saves roughly €26,503 annually against an installed cost near €90,000. Over 25 years the net saving is around €572,575, while avoiding about 60.2 tonnes of CO₂ each year.
Badajoz is in Extremadura, alongside Cáceres, Mérida and Plasencia. 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 × 1,721 kWh/kWp = 172,100 kWh of annual production on a representative warehouse or factory roof in Badajoz. Apply 70% self-consumption against €0.22 per kWh and you get about €26,503 a year. Divide the €900/kWp installed cost (€90,000 for 100 kWp) by that saving and payback lands at 3.4 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 Badajoz cannot beat roughly 3.4 years on these inputs, it is probably not a priority lead.
Badajoz versus the rest of Spain
Relative to Spain as a whole, payback in Badajoz is about 0.4 years faster than the Spain average of 3.8 years. Spain has Europe’s strongest solar resource. High specific yields on industrial estates and logistics parks make commercial rooftop solar one of the best-returning energy investments on the continent.
That is why outreach in Badajoz should open with the local number — 3.4 years and €26,503 a year on 100 kWp — not a national average that under- or over-sells the roof.
What actually changes payback on a Badajoz roof
Yield is already baked into the 1,721 kWh/kWp zone for Extremadura. 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 €0.22/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 Badajoz sites by savings instead of guessing from a map pin.
Frequently asked questions
What is the commercial solar payback in Badajoz?
About 3.4 years for a self-consuming 100 kWp rooftop in Badajoz. That uses 1,721 kWh/kWp of local yield and a tariff near €0.22/kWh, saving around €26,503 a year.
How much electricity does 100 kWp produce in Badajoz?
Around 172,100 kWh a year. Multiply the 1,721 kWh/kWp specific yield for Extremadura 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 Badajoz better than nearby towns?
Payback is in the same band as Cáceres, Mérida and Plasencia because they share the Extremadura irradiance zone. The practical difference is the stock of large, unshaded commercial roofs — SolarScout lists those in Badajoz with a pre-computed saving so you can compare sites, not just towns.
