Is solar worth it in Guardamar del Segura?
Guardamar del Segura is best known for La Marina, a large urbanisation of detached and semi-detached houses that is home to much of the town's international community. Unlike many coastal towns, only a small share of Guardamar del Segura's housing is classed as tourist accommodation — most properties here are lived in full-time. PVGIS puts annual irradiation at 2,087 kWh/m² here, giving a specific yield of 1,623 kWh per installed kWp, and for a typical home a payback of around 3.9–5.4 years.

Why Guardamar del Segura suits solar
Guardamar del Segura's housing stock — particularly across La Marina — is dominated by detached and semi-detached bungalow-style houses on individual plots, most with unshaded roofs and clear southern exposure. Because so few properties here are seasonal rentals, Guardamar del Segura's consumption pattern is steady and year-round: heating in winter, cooling in summer, every month, from owners who are actually in residence.
37.6% of Guardamar del Segura's 18,564 residents are foreign-born, mostly British and northern European retirees and working-age owners who bought a permanent home rather than a holiday let. ENERA runs design, installation and town-hall paperwork end to end, in your own language.
What does a solar installation cost in Guardamar del Segura?
A typical Guardamar del Segura home — including La Marina's bungalow-style houses — takes a 5–8 kW system, priced between €4,400 and €7,000 fully installed — panels, inverter, mounting, labour, legalisation and VAT all in one fixed, itemised quote. Flat and low-pitch roofs common here take ballasted aluminium frames tilted to about 36° for peak yield. 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 Guardamar del Segura
Guardamar del Segura's ordenanza fiscal grants a 50% IBI property-tax bonification for the three tax periods after the installation is on record, for properties with solar thermal or electric systems — you'll need the Generalitat's low-voltage self-consumption certificate for a photovoltaic install, and it must be applied for so it takes effect the following tax period. We checked Guardamar del Segura's ICIO construction-tax ordinance and found no solar clause in it, so we don't claim one.
The Comunitat Valenciana's IRPF income-tax deduction also applies: 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 and applications for both.
How much can you save on electricity in Guardamar del Segura?
With Spanish grid electricity around €0.19 per kWh and rising, a well-sized system in Guardamar del Segura can cut a household's annual bill by roughly €990–1,410. Because most Guardamar del Segura homes are occupied year-round rather than seasonally, the daily consumption pattern makes the most of what a system produces; surplus is credited under Spain's compensación de excedentes net-billing scheme. At Guardamar del Segura's irradiation levels, payback on a typical installation is around 3.9–5.4 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 Guardamar del Segura home, including La Marina, 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 and IBI bonification application with Guardamar del Segura's Ayuntamiento.
