El proyecto, promovido por Repsol a través de Solar360, contempla una inversión de 5,66 millones de euros, con una producción estimada de 3.638,5 MWh anuales y autoconsumo colectivo asociado a unos 6.300 hogares.
Why it matters: Repsol is using collective self-consumption to lock in 6,300 urban customers at once, proving that carports are the new frontline for capturing the Spanish residential market.

If you’re a local PV installer in Aragon and you aren't sweating, you aren't paying attention. This 2.48 MW project in Zaragoza isn't just about steel and silicon; it’s a masterclass in how Repsol (via Solar360) is moving to colonize the 'last mile' of the Spanish energy market. They aren't just building carports; they are building a 6,300-household subscription moat that you can't easily cross.
The Math of the €2.28/Wp Urban Asset
At €5.66 million for 2.48 MW, we are looking at a CAPEX of roughly €2.28 per Watt-peak. For a standard ground-mount utility project, that would be laughably expensive. But for urban carports with 40 EV charging points and integrated collective self-consumption (CSC) infrastructure, it’s a calculated land grab. By utilizing municipal parking lots, Repsol bypasses the 'no roof, no solar' barrier for thousands of apartment dwellers. For the 6,300 households mentioned, that’s roughly 400W of allocated capacity per home—just enough to shave the expensive peak off their bill and keep them locked into the Repsol/Solar360 ecosystem.
The 'Stickiness' Strategy
Don't be fooled by the 'green city' PR. This is a retail retention play. By bundling EV charging with collective self-consumption under the 2km radius rule (RD 244/2019), they are creating a hyper-local utility model. The Lesson for Installers: If you are still trying to sell individual 3kW systems to single-family homes in the suburbs, you are fighting for scraps. The real margins are moving toward these multi-stakeholder municipal contracts where the 'product' is a 10-year energy service agreement, not a one-time hardware sale.
The War on the Ground
We’ve seen this before with the telco rollout in the early 2000s. Big players use high-visibility municipal projects to establish brand dominance. If you want to compete, you need to stop acting like a contractor and start acting like a developer. You need to be the one proposing these PPA-funded carport models to smaller municipalities (Pueblos) before the Solar360 sales team shows up with their deep pockets and Movistar-backed marketing machine.
