A quick set of documents and property details can save a lot of back-and-forth when you ask for a solar quote in Spain. For most Costa Blanca homes, the main aim is to help the installer check roof suitability, electrical compatibility, access, and whether any ownership or community approvals may be needed.
The most useful approach is to gather the basics first: your latest electricity bill, property address, roof information, and any documents that show who owns the home and who can approve work. That usually gives a surveyor enough to decide what needs checking on site. You may also find our Solar Panels in Villamartín useful.
What to have ready before requesting a solar quote
Use this as a practical checklist rather than a fixed rule. Requirements can vary by property, especially for villas, second homes, apartments, rented properties, and homes with shared or difficult roof access. You may also find our Solar permit questions for Costa Blanca homeowners useful.
Property and ownership details
Have these to hand if you can: You may also find our Solar for Villas vs Apartments useful.
- Full property address in Spain
- Type of property: villa, townhouse, apartment, finca, etc.
- Approximate year built, if known
- Proof of ownership or the name of the person who can authorise the work
- If the property is jointly owned, the details of all relevant decision-makers
- If the home is rented or managed by an agent, confirmation of who can give permission
Electricity bill details
A recent electricity bill is often one of the most useful documents. It helps the installer understand the existing supply and typical usage. You may also find our Solar Panels in Los Balcones useful.
Useful items from the bill include: You may also find our Solar Panels in La Mata useful.
- Contract holder name
- Supply address
- CUPS number, if shown
- Tariff or rate type
- Typical monthly or annual consumption, if available from the bill history
- Any notes about single-phase or three-phase supply, if shown
If you have several recent bills, keep them together. That gives a clearer picture of how the property uses electricity across different seasons, which is particularly relevant for second homes on the Costa Blanca.
Roof and access information
The installer will usually want to know:
- Roof type: tiled, flat, metal, or mixed
- Approximate usable roof area
- Shading from trees, chimneys, neighbouring buildings, or terraces
- Orientation, if you know it
- Whether the roof is easy to reach safely
- Any known roof problems, such as leaks, loose tiles, or recent repairs
Photos can be very helpful here. A few clear pictures of the roof, the electric meter area, the inverter location if there is already one, and the access route can speed up the first assessment.
Existing electrical equipment
If you already have equipment on site, the installer may ask about:
- Existing solar panels or battery storage
- Inverter type and age, if applicable
- Consumer unit / distribution board condition
- Main electrical supply location
- Space for new equipment inside or outside the property
If you do not know the technical details, that is fine. A photo of the equipment usually helps the surveyor identify what they need.
Community, planning, or site constraints
This is especially important for apartments, townhouses, and homes in managed developments.
Check whether any of these may apply:
- Community of owners approval may be required
- There are shared roofs or shared access areas
- The property is in a protected, historic, or visually sensitive area
- Access is through a narrow street, steep drive, or gated entrance
- Scaffolding or lifting equipment may be needed
For many homes, these points are only confirmed during a survey. Still, mentioning them early helps avoid delays.
What a surveyor or installer may ask you
A good solar survey usually focuses on practical questions rather than paperwork alone. Be ready to answer:
- How much electricity do you use, and when do you use it most?
- Is the home lived in full-time, used seasonally, or rented out?
- Do you want solar panels only, or solar with battery storage?
- Are there any roof repairs planned soon?
- Where could equipment be installed safely and accessibly?
- Are there any restrictions from a community, landlord, or property manager?
If you are buying a property and want solar after completion, it can still be sensible to gather these details early. That helps you understand whether the roof and electrical setup are suitable before you commit.
Simple checklist before you ask for advice
If you want a quick summary, have these ready:
- Latest electricity bill
- Property address and type
- Ownership or authorisation details
- Photos of the roof, meter, and electrical area
- Notes on shading, roof condition, and access
- Any community or planning restrictions you already know about
- A clear idea of whether you want panels, batteries, or both
That is usually enough to start a useful conversation about your options and whether a site survey is the next step.
Why this matters on the Costa Blanca
Homes in Jávea/Xàbia, Moraira, Dénia, Calpe, Altea, Benissa and nearby areas can vary a lot in roof shape, access, and ownership structure. A villa with a straightforward roof is very different from an apartment with shared areas or a second home that is empty for part of the year.
The more accurate the early information, the easier it is to judge whether the project is straightforward or whether extra checks will be needed later.

FAQ
Do I need all the documents before asking for a quote?
No. A quote can often start with basic property and electricity information. The more detail you can provide, the easier it is to narrow down the right system and avoid follow-up questions.
What if I do not have a recent electricity bill?
Try to gather the supply details another way, such as from your online utility account, contract paperwork, or previous bills. If that is not possible, tell the installer what you can confirm and ask what else they need.
Can a survey happen without proof of ownership?
Sometimes an initial discussion can, but permission to carry out work usually depends on who has authority over the property. If the home is jointly owned, rented, or part of a community, that should be clarified early.
Do apartments need different paperwork from villas?
Often, yes. Apartments and properties in managed communities may involve shared roofs, community approval, or extra access considerations. It is best to mention this from the start.
Takeaway
For a solar quote in Spain, the most useful solar installation documents Spain homeowners can prepare are a recent electricity bill, property details, ownership or authorisation information, and a few clear photos of the roof and electrical area.
