Commercial solar payback in Béjar: 3.7 years
A self-consuming 100 kWp array on a commercial roof in Béjar typically pays back in about 3.7 years. That figure uses Béjar's specific yield of 1,581 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 158,100 kWh a year and saves roughly €24,347 annually against an installed cost near €90,000. Over 25 years the net saving is around €518,675, while avoiding about 55.3 tonnes of CO₂ each year.
Béjar is in Castile and León, alongside Valladolid, Burgos and Salamanca. 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 × 1,581 kWh/kWp = 158,100 kWh of annual production on a representative warehouse or factory roof in Béjar. Apply 70% self-consumption against €0.22 per kWh and you get about €24,347 a year. Divide the €900/kWp installed cost (€90,000 for 100 kWp) by that saving and payback lands at 3.7 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 Béjar cannot beat roughly 3.7 years on these inputs, it is probably not a priority lead.
Béjar versus the rest of Spain
Relative to Spain as a whole, payback in Béjar is about 0.1 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 Béjar should open with the local number — 3.7 years and €24,347 a year on 100 kWp — not a national average that under- or over-sells the roof.
What actually changes payback on a Béjar roof
Yield is already baked into the 1,581 kWh/kWp zone for Castile and León. 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 Béjar sites by savings instead of guessing from a map pin.
Frequently asked questions
What is the commercial solar payback in Béjar?
About 3.7 years for a self-consuming 100 kWp rooftop in Béjar. That uses 1,581 kWh/kWp of local yield and a tariff near €0.22/kWh, saving around €24,347 a year.
How much electricity does 100 kWp produce in Béjar?
Around 158,100 kWh a year. Multiply the 1,581 kWh/kWp specific yield for Castile and León 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 Béjar better than nearby towns?
Payback is in the same band as Valladolid, Burgos and Salamanca because they share the Castile and León irradiance zone. The practical difference is the stock of large, unshaded commercial roofs — SolarScout lists those in Béjar with a pre-computed saving so you can compare sites, not just towns.
