Commercial Solar Spain publishes information about commercial photovoltaic projects in Spain and coordinates enquiries from businesses considering one. We work with a single installation partner, who carries out all technical assessment, design and installation work.
We are not the installer. We do not compare installers, operate a marketplace or put projects out to several companies. This page sets out how the arrangement works, what happens after an enquiry and where the boundaries lie.
What we do
Two things.
We publish the Knowledge Centre, a set of guides covering how commercial solar operates in Spain, how systems are sized, what determines cost and return, how the regulatory position works and how to judge a proposal.
We also receive enquiries from businesses, review them against our installation partner's project criteria and introduce those that appear suitable.
That is the whole of the role. We do not install solar systems, employ the installation team, carry out feasibility studies or provide engineering, structural or financial advice.
What happens after an enquiry
The sequence matters, particularly the point at which information moves.
You send basic project details. Location, property type, roughly what the business consumes, roof availability and anything you already know about the site. Enough for a first view, not a full technical picture.
We review it. Against the installation partner's project criteria, to establish whether it is likely to be a project they can take on.
We tell you who the installation company is. If the enquiry appears suitable, we identify them by name before anything else happens.
You decide whether to proceed. Submitting the initial form does not commit you to anything and does not create a contract.
Only then is information shared for technical assessment. Nothing goes to the installation partner for that purpose until you have agreed to proceed.
The installation company carries out the assessment and issues the proposal. Site survey, structural and electrical position, generation modelling against your consumption, capacity options and costs.
If the project goes ahead, you contract with them directly. Commercial Solar Spain is not a party to that contract.
How the initial information is handled is set out in the Privacy Notice.
Working with one partner
We work with one installation partner rather than distributing enquiries to several businesses.
This means you are not receiving a shortlist or a competitive tender through this website. If our partner is not suitable for the project, we are not in a position to find another installer on your behalf.
There is no charge to you for the introduction. We may receive a fee from the installation partner when an introduced project proceeds. We think you should know that when reading anything on this site.
Why we suggest comparing proposals
Because we work with one company, we would encourage you to benchmark whatever proposal you receive against alternatives.
A commercial solar installation is a long-term capital commitment. More than one reference point gives the buyer a better basis for judging its scope, assumptions and price.
We have published our own method in how to compare commercial solar quotes in Spain. It covers normalising quotations onto the same scope, checking a generation model against its inputs, testing savings figures and identifying costs left outside the headline price. It can be used against any proposal, including one that arrives through us.
The companion guide on what a feasibility study should include sets out what a proper assessment examines and what it should state it has not examined.
How the Knowledge Centre is prepared
The guides exist so a business can understand the main technical, financial and regulatory questions before committing to a project.
Regulatory statements are drawn from primary sources, principally the BOE for Spanish legislation, along with material published by MITECO, IDAE, the CNMC and the European Commission's Joint Research Centre. Sources are linked so they can be checked.
Verified regulatory facts are kept separate from illustrative calculations. Worked examples state every assumption and are labelled as illustrative, so a reader can substitute their own figures rather than treating ours as market averages.
Several distinctions are maintained consistently. Panel capacity in kWp is not the same as inverter installed capacity in kW, and the Spanish definition of photovoltaic installed capacity is based on inverter capacity. Self-consumed, exported and curtailed electricity are treated separately.
No article promises a universal price, saving or payback period. Those figures depend on the building, consumption profile, tariff and connection. Time-sensitive articles carry review dates because tariff values, tax rates and regulatory provisions can change.
The guidance is written to encourage readers to interrogate any proposal they receive, which includes ours.
Who carries out the technical work
Technical assessment, design, proposals and project delivery are handled by the installation partner. The proposal must identify the work included, any exclusions and responsibility for the applicable technical and administrative steps.
Their staff are theirs, not ours. Where the material on this site describes what an assessment should examine or what a proposal should contain, it is describing a standard rather than making a promise on another company's behalf.
The three services we take enquiries for are commercial solar installation, industrial and warehouse solar and large commercial solar systems, including projects above 100 kW.
Where the service is available
Mainland Spain and the Balearic Islands.
Coverage does not mean a uniform process. Municipal works procedures are set by each town hall, registration and legalisation are administered by the autonomous community, and the distributor serving the site determines the connection procedure and what capacity is available. Establishing which route applies to a particular building is part of the technical assessment rather than something that can be answered nationally.
If a site falls outside the delivery area, we will say so at enquiry stage rather than after you have committed time to it.
Request an assessment
Send your site details and we will review the enquiry against our installation partner's project criteria. If it appears suitable, we will identify the installation company and confirm the next step with you before anything proceeds.
