Quick Answer
These are modelled examples, not customer submissions and not market averages. The optimal configuration depends on your actual consumption, roof orientation, battery needs, and choosing the right export tariff.
Important status: illustrative, not observed data
No scenario below was submitted by a customer or issued by a named installer. None is presented as an average, cheapest price or recommendation.
We modelled plausible scopes within broad local market ranges to teach readers how property type, access, battery storage and electrical design change a quote. The public index will only describe observed market statistics after enough genuine, permissioned quotes have passed our checks.
Four worked quote scenarios
Compact coastal home
Illustrative exampleTorrox Costa | Townhouse, straightforward tiled roof
3.6 kWp / 8 panels | String inverter, no battery
EUR 4,700 (EUR 1,306/kWp)
Includes standard access, mounting, protections, CIE and legalisation allowance.
Pool villa
Illustrative exampleNerja | Detached villa, pool and daytime cooling
5.4 kWp / 12 panels | Hybrid-ready inverter, no battery
EUR 6,450 (EUR 1,194/kWp)
Allows for split roof orientation and a longer cable route.
Mountain finca
Illustrative exampleCompeta | Rural home, difficult access and pump loads
6.3 kWp / 14 panels | Hybrid inverter plus 10 kWh battery
EUR 12,900 (EUR 2,048/kWp incl. battery)
Includes access allowance and battery; not comparable with panel-only EUR/kWp.
Large three-phase villa
Illustrative exampleMijas | Villa with pool, ducted cooling and EV
9.0 kWp / 20 panels | Three-phase hybrid inverter, no battery
EUR 10,300 (EUR 1,144/kWp)
Includes three-phase equipment and multi-roof design allowance.
How we made the examples realistic
Each scenario starts with a defined property, DC system size and scope. We allow for VAT, panels, inverter, mounting, standard protections, labour and ordinary certification/legalisation work, then vary access, battery and electrical complexity. Exact contractor prices will differ.
EUR/kWp is useful only when scopes are equivalent. A battery, backup gateway, scaffolding, trench, switchboard replacement or premium mounting system can make a good quote look expensive under a crude division.
Rules for the future observed-price index
- Remove names, contact details, CUPS and exact addresses.
- Record quote date, municipality, system size, battery, VAT and inclusions.
- Verify that totals and equipment can be read from the submitted document.
- Separate modelled examples from observed quotes at all times.
- Do not rank an installer from one quote.
- Publish medians or ranges only when the sample is large enough to avoid identifying a household.
- Show sample size and collection period beside every statistic.
What to compare in your own quote
Compare exact panel and inverter models, DC and AC power, annual-production basis, self-consumption assumption, battery usable capacity, backup scope, mounting, access, electrical remedial work, municipal process, CIE, registration, warranty labour and payment milestones.
