Remote self-consumption in Mazarrón: solar panels for people who cannot install them at home

Comunidad Solar, co-founded by Eugenio García-Calderón Huerta, founder of Light Humanity, brought remote self-consumption to Mazarrón (Murcia): panels in a solar park for people who cannot put them on their own roof. In 2023, a Madrid couple with three panels there paid €4.51 on their latest electricity bill, according to Antena 3.

  • What it is: remote self-consumption for people who cannot put panels on their homes: they choose panels in a solar park, pay for their energy up front and receive it on their bill.
  • Where: in a solar park in the municipality of Mazarrón (Region of Murcia), more than 450 km from Madrid.
  • With whom: Comunidad Solar, the company co-founded by Eugenio García-Calderón Huerta, founder of Light Humanity, which in 2023 showed its “Megapark Las Vegas” on video.
  • How it works: each member's panels are identified in the park and, on their bill, the energy that matches their home's consumption appears at €0.00/kWh.
  • Outcome: in 2023, Madrid residents with panels in Mazarrón showed Antena 3 electricity bills close to zero, and one in credit.
  • What's next: all the places in Comunidad Solar's operating parks have been taken, and the next one, in Chiva (Valencia), is due to open in 2027.

No roof of your own: how remote self-consumption works

Many families cannot install solar panels at home: they have no room on the roof, they rent, or their residents' association cannot reach an agreement. For them, Antena 3 Noticias presented remote self-consumption as “the solution”. Comunidad Solar offers it with panels in solar parks hundreds of kilometres away.

  • Identified panels: each member chooses how many panels they need, and these are identified in a real solar plant (Comunidad Solar).
  • No building work: there is nothing to install or maintain at home; the company operates the park.
  • On the bill: the Megapark tariff from the Comunidad Solar energy retailer charges €0.00/kWh for the energy that matches consumption.
  • Any surplus: excess energy is sold hour by hour and its value builds up in a digital wallet.

2020: the Region of Murcia authorises the 1 MWp “Las Vegas” solar plant in Mazarrón

The name Megapark Las Vegas matches that of a plant in Mazarrón: on 10 February 2020, the company Torrontera Solar S.L. applied for permission to build the “Planta Solar Fotovoltaica ‘Las Vegas’ 1 MWp” there. The Official Gazette of the Region of Murcia published its prior authorisation and construction permit on 28 August.

  • No objections: nobody lodged objections during the public consultation period.
  • 2,436 panels in the project: 410 Wp modules on single-axis trackers, which turn to follow the sun.
  • Grid connection: a 1,000 kVA transformer station and a 195-metre, 20 kV underground line.
  • Twelve months: the deadline for building it once all permits were in place.

2023: a flat in Madrid, three panels in Mazarrón and an electricity bill of €4.51

In August 2023, Antena 3 Noticias told the story of Óscar and Paula, a couple of programmers who work from home in an all-electric 85 m² flat in Madrid. Their residents' association will not let them install panels, so theirs are “more than 450 kilometres away in a solar park in Mazarrón”.

  • Three panels: they had owned them for a few months and their latest electricity bill was €4.51, with the air conditioning running all day.
  • Javier, renting in Moratalaz: his panels are also in Mazarrón; he went from paying more than €70 a month to a credit of about €33.
  • The investment: between €3,500 and €4,000 for an average home, according to Eugenio García-Calderón.
  • The savings: up to 70% of the bill, the part that corresponds to energy, according to the broadcaster; the remaining 30% is tolls, distribution and contracted power.
“The investment is recovered in about 6 or at most 7 years” — Eugenio García-Calderón Huerta, co-founder of Comunidad Solar (Antena 3 Noticias)

On 20 September 2023, Comunidad Solar published a 34-second video on YouTube with aerial footage of one of its parks. Its description invites viewers to “explore Megapark Las Vegas, where Remote Self-Consumption is a reality” (YouTube).

  • Megapark: also the name of the Comunidad Solar energy retailer's tariff for remote self-consumption.
  • Earlier, Fuente Álamo: in early June 2023, the company opened Megapark Fuente Álamo, also in Murcia (video).

2024: Comunidad Solar already had 1,089 homes and businesses on remote self-consumption

Diariomotor tried the service from early 2024 and in September reported a 63.7% reduction in its electricity bill. According to that outlet, Comunidad Solar was then close to filling the capacity of its two operating plants.

  • 1,089 homes and businesses had already switched to Comunidad Solar's remote self-consumption, with another 100 cases under review, according to the same article.
  • The first park: Diariomotor placed it “in the Region of Murcia, specifically in Fuente Álamo and Mazarrón”.
  • The second: the 500 kW Ligüérzana mini hydropower plant, on the River Pisuerga (Pisuerga Hydroelectric Plant).
  • 30 years: according to Diariomotor, customers at the time held exclusive use rights over their contracted capacity for three decades.

Torrontera: 3,808 panels and 4 MWh of batteries for remote self-consumption in Murcia

The “Las Vegas” plant in Mazarrón was taken through the permitting process by the company Torrontera Solar S.L. Torrontera is also the name of the two plants that Comunidad Solar presented on 19 June 2025 as its “fourth Remote Self-Consumption project, located in Murcia” (Instagram).

  • Two plants: Torrontera I has been producing since August 2023 and Torrontera II since March 2024; both joined Comunidad Solar in 2025.
  • Capacity: 3,808 panels of 540 W, around 2.06 MWp, with single-axis solar tracking (Torrontera project page).
  • Batteries: 4 MWh at the park itself; according to company figures reported by Diariomotor, up to 34% of the energy can be stored for early morning and night-time use.
  • 40 years: its community members pay in advance for the energy from a specific share over four decades; no places remain.

The battery is not home backup for a blackout, Comunidad Solar makes clear: it serves to shift part of the solar output to other hours.

What's next: the Chiva park and shared energy close to home

  • Full parks: Torrontera, Fuente Álamo and Ligüérzana are still producing and all their places have been taken (Comunidad Solar).
  • Chiva (Valencia): the next park, an agrivoltaic one with 4.5 MWp and 4.8 MWh of batteries, is under construction and expected to open in 2027.
  • Villalbilla and Nuevo Baztán: shared energy is already reaching the first members of Villalbilla Community and Nuevo Baztán Community; in Villalbilla, savings in the first cases range from 23% to 44% (Comunidad Solar).

It is the same idea, only closer: in an energy community, a roof in the municipality produces energy that is shared among nearby homes and small businesses, with no need for panels on every rooftop.
