Factory rooftop solar in Colmenar Viejo: 164,300 kWh a year on 100 kWp
A 100 kWp array on a factory roof in Colmenar Viejo generates about 164,300 kWh a year at the local specific yield of 1,643 kWh/kWp. Factories are a better solar match than most commercial buildings because process loads, compressed air and HVAC run through the same daylight hours the array is producing.
With roughly 70% self-consumed against €0.22/kWh, that output is worth about €25,302 a year and pays back in around 3.6 years on an installed cost near €90,000. Strong local irradiance plus daytime process load is why factory rooftops in Colmenar Viejo are usually faster to close than speculative warehouse pitches.
Industrial estates around Colmenar Viejo sit in the same Madrid band as Madrid, Móstoles and Alcalá de Henares. What changes site to site is roof area, shading from plant rooms, and whether the factory runs a true day shift. SolarScout flags those roofs from satellite and OpenStreetMap rather than from a bought list.

A quiet distribution shed may export a large share of midday generation. A factory in Colmenar Viejo typically does not: motors, ovens, plating lines or refrigeration pull power while the sun is up, so a higher share of the 164,300 kWh stays behind the meter and the 3.6-year payback holds.
That is the conversation to open with — not "solar is green", but "this roof in Colmenar Viejo offsets about €25,302 a year at today's tariff of €0.22/kWh".
What to inspect on a Colmenar Viejo factory roof
Look for large, low-pitch structural roofs with few roof lights, limited HVAC clutter, and a south or east-west run that matches Madrid's 1,643 kWh/kWp resource. North-light sheds and heavily plant-loaded roofs still work, but usable kWp drops and payback stretches past the 3.6-year city example.
SolarScout estimates footprint first, then (where Google Solar data exists) modelled annual kWh, so you can skip the roofs that will never carry a 100 kWp array and spend time on the ones that will.
How to turn Colmenar Viejo factory roofs into a lead list
Scan Colmenar Viejo in SolarScout and filter for factories. Each row carries an estimated roof area, a worked saving at €0.22/kWh, and contact fields where map data provides them. Export CSV or Excel and drop the list into your CRM.
When Colmenar Viejo is thin, run the same scan on Madrid, Móstoles and Alcalá de Henares — they share the Madrid yield, so the economics stay comparable and you are not mixing a sunny coast with a cloudy hinterland.
Frequently asked questions
How much can a factory rooftop in Colmenar Viejo generate?
About 164,300 kWh a year on a 100 kWp array. That is 100 kWp multiplied by Colmenar Viejo's specific yield of 1,643 kWh/kWp; larger roofs scale linearly until structure, shading or grid export caps the design.
What payback does factory rooftop solar see in Colmenar Viejo?
Around 3.6 years when most of the generation is used on site. Factories usually beat empty warehouses on that score because daytime process load matches the solar curve.
How does SolarScout find factory rooftops in Colmenar Viejo?
It combines OpenStreetMap industrial building tags with satellite imagery and, where available, Google Solar modelling — then exports Colmenar Viejo factories as leads with roof area and a €25,302/year worked example on 100 kWp.
