Aldea
On-site PPA for companies

Solar energy at your business, with zero investment

We install solar panels on your roof or land at no cost to you. You simply buy the energy they generate, at a stable, lower price for the whole contract. No works on your side, no surprises.

Why an on-site PPA

The benefits, made clear

You don't buy an installation: you only pay for the solar energy you use. That cuts your bill from day one without touching your cash.

Zero upfront investment

We finance, install and own the panels. You put in no money and take on no special charges.

Stable, competitive energy price

You pay for solar energy at a fixed price that's lower than the grid, shielded from market swings for the entire contract.

Maintenance included

We handle the operation, maintenance and warranty of the installation. You don't have to worry about a thing.

Lower emissions

Every solar kWh you use is 100% green energy generated on your own roof. You cut your carbon footprint in a measurable way.

No risk for your business

No debt on your balance sheet and no construction commitments. If the panels don't generate, you don't pay. You only pay for the energy you receive.

How it works

From your roof to your bill, step by step

01
We study your usage and your roof

We review your bills, your consumption profile and the space available on your roof or land to size the installation to fit you.

02
We install at no cost to you

We design, finance and install the panels. The investment and the works are on us, not on you.

03
You sign the PPA

We agree on a clear price for the solar energy and the contract length. Everything in writing, no fine print.

04
You use cheaper solar energy

From then on you use the energy your panels generate at a stable, competitive price, and you only pay for what you use.

Who it's for

Built for companies with consumption and space

If your business uses energy during the day and you have roof or land available, an on-site PPA is a great fit.

Industry

Factories and plants with high, steady consumption that want to stabilise costs and decarbonise their production.

Logistics and warehouses

Logistics centres and warehouses with large roofs, ideal for generating plenty of solar energy on space you already have.

Retail and large stores

Supermarkets, shopping centres and stores with daytime consumption looking to cut bills and strengthen their green commitment.

Frequently asked questions

What you usually want to know

Do I have to invest anything? +

No. The investment in the panels and the installation is ours. You put in no capital and take on no extra charges: you only pay for the solar energy you use.

How long does the PPA last? +

They are usually medium to long-term contracts, typically several years, so the installation makes sense and you enjoy a stable price throughout. We agree the exact length based on your project.

Who owns the installation? +

During the contract the panels are ours: we are the owners and we take care of maintenance and the warranty. You benefit from the energy they generate without the obligations of ownership.

What happens when the contract ends? +

We make it clear from the start. Depending on what we agree, the installation can become yours, the agreement can be renewed, or we remove the panels. You choose the option that suits you best.

How is it different from traditional self-consumption? +

With classic self-consumption you buy the installation and take on the investment. With an on-site PPA you buy nothing: you only pay for the solar energy you use, at a fixed, lower price, with no upfront outlay.
