Commercial solar payback in Cabra: 3.3 years
A self-consuming 100 kWp array on a commercial roof in Cabra typically pays back in about 3.3 years. That figure uses Cabra's specific yield of 1,767 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 176,700 kWh a year and saves roughly €27,212 annually against an installed cost near €90,000. Over 25 years the net saving is around €590,300, while avoiding about 61.8 tonnes of CO₂ each year.
Cabra is in Andalusia, alongside Seville, Málaga and Córdoba. 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 × 1,767 kWh/kWp = 176,700 kWh of annual production on a representative warehouse or factory roof in Cabra. Apply 70% self-consumption against €0.22 per kWh and you get about €27,212 a year. Divide the €900/kWp installed cost (€90,000 for 100 kWp) by that saving and payback lands at 3.3 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 Cabra cannot beat roughly 3.3 years on these inputs, it is probably not a priority lead.
Cabra versus the rest of Spain
Relative to Spain as a whole, payback in Cabra is about 0.5 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 Cabra should open with the local number — 3.3 years and €27,212 a year on 100 kWp — not a national average that under- or over-sells the roof.
What actually changes payback on a Cabra roof
Yield is already baked into the 1,767 kWh/kWp zone for Andalusia. 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 Cabra sites by savings instead of guessing from a map pin.
Frequently asked questions
What is the commercial solar payback in Cabra?
About 3.3 years for a self-consuming 100 kWp rooftop in Cabra. That uses 1,767 kWh/kWp of local yield and a tariff near €0.22/kWh, saving around €27,212 a year.
How much electricity does 100 kWp produce in Cabra?
Around 176,700 kWh a year. Multiply the 1,767 kWh/kWp specific yield for Andalusia 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 Cabra better than nearby towns?
Payback is in the same band as Seville, Málaga and Córdoba because they share the Andalusia irradiance zone. The practical difference is the stock of large, unshaded commercial roofs — SolarScout lists those in Cabra with a pre-computed saving so you can compare sites, not just towns.
