Solar panels for your building, with no investment from the association

Aldea invests in the installation in exchange for renting the roof. Residents benefit from collective self-consumption, with no special levies, and add value to the property.

What the association gains

Solar energy with no money from the association

No investment, no levies

Aldea funds the entire installation. The association pays nothing upfront: the roof is rented for 15-30 years.

Maintenance and insurance included

Throughout the rental we handle maintenance and insurance of the installation. Zero worries.

Savings on shared services

The panels power the lift, garage, entrance or pool and reduce the building’s common bill.

A coefficient for each resident

Each resident can buy or subscribe to their coefficient and self-consume solar energy at home. Joining is voluntary.

Adds value to the property

A building with self-consumption is more efficient and attractive, improving its sale and rental value.

The installation becomes the association’s

When the rental ends, the entire installation becomes the property of the association.

How we do it

From the meeting’s approval to solar energy

01
1 · Approval at the meeting

The association approves the project (a 3/5 majority of votes is enough). We help you present it.

02
2 · Sign the contract

You sign the roof-rental agreement with Aldea, with clear terms and no fine print.

03
3 · Participating residents

We identify which residents want their coefficient, by purchase or subscription.

04
4 · Paperwork with the grid operator

We open the file with the grid operator (I-DE, E-Distribución, UFD…) and design the installation.

05
5 · Permits and installation

We manage the municipal permits and install the panels on the roof.

06
6 · Legalisation and grants

We handle legalisation (CIE) and the available grants. The energy starts to flow.

How it works

Collective self-consumption, made simple

The coefficient is the share of installed capacity each resident assigns to their own consumption.

Buying a coefficient

You acquire your share of the installation and enjoy its energy throughout its useful life.

Subscribing to a coefficient

You pay a flexible fee to use your coefficient, with no upfront purchase. Ideal to start with no commitment.

Clean, local energy

You consume solar energy generated in your own building, lowering your bill and your emissions.

Joining is voluntary

Each resident decides whether to join. Unsold coefficients go to the association at the end of the rental.
