Is solar worth it in Alfaz del Pi?
Alfaz del Pi — l'Alfàs del Pi — sits inland between Altea and Benidorm, its resident population older and more settled than most towns on this coast. PVGIS puts annual irradiation at 2,117 kWh/m² here, giving a specific yield of 1,663 kWh per installed kWp, and for a typical home a payback of around 3.7–5.2 years.

Why Alfaz del Pi suits solar
Alfaz del Pi's housing stock mixes detached and semi-detached houses in residential urbanisations with lower-rise apartment blocks, most with unshaded roofs and clear southern exposure away from the coastal high-rises further east. At 49.3% foreign-born and with a resident population that skews notably older than most towns ENERA serves on this coast, Alfaz del Pi is a community of largely retired, full-time residents rather than seasonal visitors.
With an average income of about €12,274 per resident, these households typically run heating in winter and cooling through the long Costa Blanca summer every day of the year — exactly the steady, year-round consumption pattern that makes solar pay back fastest. ENERA runs design, installation and town-hall paperwork end to end, in your own language.
What does a solar installation cost in Alfaz del Pi?
A typical Alfaz del Pi home takes a 6–10 kW system, priced between €5,300 and €8,300 fully installed — panels, inverter, mounting, labour, legalisation and VAT all in one fixed, itemised quote. Flat-roofed houses take ballasted aluminium frames tilted to about 36° for peak yield; tiled roofs take corrosion-resistant hooks. Every installation connects through i-DE, the Iberdrola-group distributor for Alicante province, and we manage that paperwork for you.
Solar incentives and tax breaks in Alfaz del Pi
We read Alfaz del Pi's IBI ordinance in full: it does carry a 25% solar clause, but as drafted it only reaches properties whose cadastral record shows health-related ('sanitario') use over more than a quarter of the built surface, and requires the installation to be both thermal and electric together — conditions a normal residential rooftop doesn't meet. So for a typical Alfaz del Pi home, there is no usable IBI discount today, and the current ICIO ordinance grants no bonification beyond what's already set by national law. We'd rather tell you that plainly than quote a benefit you wouldn't actually receive.
What does apply is the regional layer: the Comunitat Valenciana's IRPF income-tax deduction of up to 40% of the installation cost for a habitual residence (around 20% for a second home), claimed on your annual declaración de la renta, up to €8,800 per dwelling per year. ENERA prepares the certificates you need to claim it.
How much can you save on electricity in Alfaz del Pi?
With Spanish grid electricity around €0.19 per kWh and rising, a well-sized system in Alfaz del Pi can cut a household's annual bill by roughly €1,240–1,780. Full-time, year-round occupancy — typical of Alfaz del Pi's largely retired resident base — makes the most of what a system produces; surplus is credited under Spain's compensación de excedentes net-billing scheme. At Alfaz del Pi's irradiation levels, payback on a typical installation is around 3.7–5.2 years.
How your installation works, start to finish
ENERA runs the whole project as a single turnkey service. It starts with a remote design from satellite imagery and a recent electricity bill, sizing the system to your real consumption and sending a fixed, itemised quote. Installation on a typical Alfaz del Pi home takes one to two days on the roof. In parallel we prepare and submit every document: the technical memoria, the electrical certificate (boletín), i-DE registration and the compensación de excedentes agreement, plus the municipal licence with Alfaz del Pi's Ayuntamiento. You sign; we file.
