Is solar worth it in Alicante?
Yes, and this is the province ENERA knows best. A roof in Alicante produces about 1,627 kWh a year for every kWp installed (PVGIS, measured at the provincial capital), so a 4–8 kWp family system takes roughly €910–€1,300 a year off the electricity bill and pays for itself in about 3.9–5.4 years.
ENERA works out of Altea, on this province’s own coast. 382 installations of ours are already in Alicante — 1,267 kW of them.
What a roof in Alicante actually looks like
Alicante/Alacant holds 2,033,566 residents along a coast that changes character every few kilometres, and the roof is what decides the system. North of Alicante, the Marina Alta and Marina Baja are villa-and-urbanisation country: tiled pitched roofs, pools, and a good share of houses that stand empty for part of the year. South and inland of the capital, the Alicante–Elche axis is flats, terraced housing and industrial estate, where a flat azotea and a shared building are the norm. The Vega Baja around Torrevieja is dense low-rise housing owned largely by foreign residents. The coast inside this province is the Costa Blanca.
How much does a solar installation cost in Alicante?
A turnkey home system in Alicante costs about €3,700–€7,000 with VAT included for 4–8 kWp: panels, inverter, mounting, wiring, the installation itself, the legalisation and the change to a self-consumption contract, all in one figure. What moves the number in this province is the roof and the household, not the postcode. A flat roof needs ballasted frames; a tiled villa roof in the Marina Alta needs hooks and rails; a house with a pool pump and air conditioning usually justifies more kWp than an apartment that is occupied for three months a year. Battery storage is quoted separately, because it earns its price only where a real share of the consumption happens after sunset.
What tax relief applies in Alicante?
Comunitat Valenciana has a renewables deduction of its own, which not every comunidad does. The autonomic IRPF deduction is 40% of what you invest in a self-consumption installation at a main residence, or 20% at a second home, on a deduction base of up to €8,800 per dwelling per year. The property has to be in Comunitat Valenciana, the payment has to be traceable — card, transfer, cheque or bank deposit — and anything covered by a public grant does not count.
On top of that, Spanish state law lets each ayuntamiento discount up to 50% of the IBI and up to 95% of the ICIO, but only where its own ordenanza fiscal creates that discount. That is why the incentives block on this page names the Alicante towns whose ordinance we have read and says nothing about the others. The national IRPF deductions are a different thing again: they are earned by a measured improvement in the dwelling, evidenced by energy performance certificates issued before and after the works, so they are never quoted here as a discount on a solar system.
What do you actually save in Alicante?
The band is €910–€1,300 a year for a 4–8 kWp system, and where a house lands inside it depends almost entirely on how much of its own production it uses instead of exporting. The low end describes a home that is empty all day; the high end a household running air conditioning, a pool pump, the washing machine or an EV charger while the sun is up — which on this coast is most of the year. For scale, INE puts the average household in Comunitat Valenciana at €920 a year on electricity (2025); that is a consumption figure, not a local tariff. Exported surplus is credited on the bill under compensación de excedentes, which reduces the bill but never removes the fixed charges. Payback works out at 3.9 to 5.4 years.
How much of Alicante does ENERA really cover?
All of it, and here that is not a stretch: our crews leave from Altea, inside this province, 13 years into the business and with 4.7★ over 126 Google reviews behind them. 382 installations and 1,267 kW of ours are already in Alicante. The towns with their own page are Torrevieja, Calpe, Jávea, Altea, Dénia, Finestrat, Orihuela, Benidorm, Elche, Moraira, La Nucía, Alfaz del Pi, El Campello, Rojales, Villajoyosa, Benitachell, Els Poblets, Benissa, Santa Pola, Guardamar del Segura. A town missing from that list is not outside the service area — it simply has no page yet — and an inland address is the same day trip as a coastal one. Site visits, warranty call-outs and the after-sales conversation all happen from inside the province, which is the part that is hard to reproduce from another region.
The paperwork in Alicante, in order
Three counterparties, always in the same order. Your ayuntamiento receives a declaración responsable or a works licence with a memoria técnica attached. The finished installation gets its electrical certificate and is registered as self-consumption. The supply point is then updated with i-DE, the distributor whose network covers Alicante, and only once that registration is through does compensación de excedentes start crediting exports on your bill. None of it depends on residency: an owner with a NIE and the escritura installs on exactly the same terms as a resident. The timings belong to the ayuntamiento and to i-DE rather than to any installer, so panels usually produce within days while the registration finishes in the weeks after.
