Is solar worth it in Rojales?
Rojales's Ciudad Quesada urbanisation is a sprawl of bungalow-style detached and semi-detached houses, home to a mostly retired, mostly British and northern European community — 67.7% of Rojales's 17,652 residents are foreign-born, and the resident population here skews among the oldest of any town ENERA covers. PVGIS puts annual irradiation at 2,136 kWh/m² here, giving a specific yield of 1,659 kWh per installed kWp, and for a typical home a payback of around 3.8–5.3 years.

Why Rojales suits solar
Ciudad Quesada's housing stock is almost entirely low-rise bungalow and single-storey villa construction, with flat or low-pitch roofs, private pools, and virtually no shading from neighbouring buildings — about as clean a solar site as this coast offers. Only a small share of housing here is classed as tourist accommodation, so most of these homes are lived in full-time, not let seasonally.
With a largely retired resident population, Rojales households are typically in residence every day of the year, running heating, cooling and pool equipment on a steady, predictable schedule — exactly the 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 Rojales?
A typical Rojales bungalow or villa — including Ciudad Quesada properties — 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-roofed bungalows take ballasted, non-penetrating 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 Rojales
Rojales's ordenanza fiscal grants a 50% IBI property-tax bonification for the five tax periods after installation, on urban residential property, where the self-consumption system supplies at least 20% of the property's total energy use — you'll need to apply within three months of installation. A separate 95% ICIO construction-tax bonification applies to the solar share of the works budget.
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 all of it, and files the IBI request within the three-month window Rojales's ordinance requires.
How much can you save on electricity in Rojales?
With Spanish grid electricity around €0.19 per kWh and rising, a well-sized system in Rojales can cut a household's annual bill by roughly €1,010–1,440. Full-time, retired occupancy — the norm across Ciudad Quesada and the wider town — makes the most of what a system produces every day of the year; surplus is credited under Spain's compensación de excedentes net-billing scheme. At Rojales's irradiation levels, payback on a typical installation is around 3.8–5.3 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 Rojales bungalow 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 Rojales's Ayuntamiento — filed within the three-month window the ordinance sets. You sign; we file.
