Factory rooftop solar in Vila do Conde: 147,000 kWh a year on 100 kWp
A 100 kWp array on a factory roof in Vila do Conde generates about 147,000 kWh a year at the local specific yield of 1,470 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 €0.20/kWh, that output is worth about €20,580 a year and pays back in around 4.4 years on an installed cost near €90,000. Strong local irradiance plus daytime process load is why factory rooftops in Vila do Conde are usually faster to close than speculative warehouse pitches.
Industrial estates around Vila do Conde sit in the same Porto District band as Porto, Vila Nova de Gaia and Matosinhos. 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 Vila do Conde typically does not: motors, ovens, plating lines or refrigeration pull power while the sun is up, so a higher share of the 147,000 kWh stays behind the meter and the 4.4-year payback holds.
That is the conversation to open with — not "solar is green", but "this roof in Vila do Conde offsets about €20,580 a year at today's tariff of €0.20/kWh".
What to inspect on a Vila do Conde 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 Porto District's 1,470 kWh/kWp resource. North-light sheds and heavily plant-loaded roofs still work, but usable kWp drops and payback stretches past the 4.4-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 Vila do Conde factory roofs into a lead list
Scan Vila do Conde in SolarScout and filter for factories. Each row carries an estimated roof area, a worked saving at €0.20/kWh, and contact fields where map data provides them. Export CSV or Excel and drop the list into your CRM.
When Vila do Conde is thin, run the same scan on Porto, Vila Nova de Gaia and Matosinhos — they share the Porto District 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 Vila do Conde generate?
About 147,000 kWh a year on a 100 kWp array. That is 100 kWp multiplied by Vila do Conde's specific yield of 1,470 kWh/kWp; larger roofs scale linearly until structure, shading or grid export caps the design.
What payback does factory rooftop solar see in Vila do Conde?
Around 4.4 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 Vila do Conde?
It combines OpenStreetMap industrial building tags with satellite imagery and, where available, Google Solar modelling — then exports Vila do Conde factories as leads with roof area and a €20,580/year worked example on 100 kWp.
