Enera Solar: turnkey solar installation from the Costa Blanca

Enera Solar is the trading name of IBERSUNWIND, S.L., a company registered at the Mercantile Registry of Alicante with tax ID B54715099. It has operated since 2013, holds civil-liability insurance and runs its own office-warehouse in Altea, on the Costa Blanca. The company states it has completed more than 626 installations and generated over 6 GWh, and its main service area is the Costa Blanca, although it works across Spain and takes on large projects in France, Portugal and Italy on demand.

Online 3D design and closed pricing

The company's working method is built around remote assessment rather than site visits. Customers upload an electricity bill or enter an address and receive a 3D model of their roof with the panel layout, a closed price and an estimated payback period, which the company says takes about two minutes. The platform reads the consumption data from the bill automatically. Enera Solar presents this as a real model of the roof rather than a generic estimate, with a stated yield accuracy of around ±2%.

Quotes are described as closed turnkey prices valid for 30 days. A 10% deposit reserves the installation date and is refundable up to 14 days beforehand; the remainder is paid on the installation day. Installation itself is scheduled over one to two days, and the company says it assists customers with the IRPF deduction and the IBI rebate.

Turnkey kits and catalogue

The catalogue is organised around validated systems from 3 kW to 20 kW with installation included. Four kits are presented as the most common sizes, with prices including VAT, installation, town-hall legalisation and warranty:

• Basic 3 kW for one to two people with low consumption: 2,961 €, estimated annual savings of 562 €.
• Family 5 kW for three to four people with medium consumption: 4,422 €, estimated savings of 936 € per year.
• Premium 8 kW for four to six people with air conditioning and an electric vehicle: 6,919 €, estimated savings of 1,497 € per year.
• Villa 12 kW for a large house with high consumption: 10,482 €, estimated savings of 2,246 € per year.

Beyond the kits, the catalogue includes lithium batteries (Growatt APX, AXE and AURA) from 1,210 €, EV chargers from 1,319 €, voltage stabilisers for areas with unstable mains supply, and solar water heaters and aerothermal tanks. Customers can also configure a system component by component, choosing panels, inverter, battery and charger with live pricing and only compatible options.

Components and installation scope

The turnkey price covers JA Solar or Tensite panels, a Growatt inverter and battery, mounting on tile or sheet-metal roofs, the town-hall legalisation through the Declaración Responsable de Obra Menor, and the switch of the supply contract to autoconsumo with the electricity provider. The company frames its pricing around five factors: annual consumption, roof type and orientation, whether a lithium battery is included, whether an EV charger is added, and the region with its available subsidies.

On roofs, it notes that a south-facing tile roof at 30° is optimal, that a flat roof requires a tilted structure (around 400 € more), that east or west orientation reduces annual production by 5-15%, and that slate or asbestos cement complicates installation (300-800 € more). A battery of 5-15 kWh adds roughly 2,200-4,500 €, and a Growatt EV charger integrated with the system adds 750-1,200 € including installation and protection panel.

Sizing guidance and when a battery pays off

Enera Solar advises sizing a system to cover 70-90% of real annual consumption, buying the remainder from the grid at off-peak rates. Its reference table links consumption bands to system size: under 3,000 kWh per year, 3 kW with six panels and an optional battery; 3,000-6,000 kWh, 5 kW with 10-12 panels; 6,000-9,000 kWh, 8 kW with 16 panels and a recommended battery; above 9,000 kWh, 12 kW or more with 20-plus panels and a required battery.

The company identifies three scenarios where a lithium battery makes sense: when more than 40% of consumption happens at night, when the home is in an area with frequent outages (it cites rural Costa Blanca, Sierra de Madrid and inland Andalucía), or when the goal is maximum energy autonomy. Where consumption is mostly daytime, it tends to recommend starting without a battery and adding one later. It also argues for installing an EV charger at the same time as the solar system, since the electrical work is done in one go and the charger, inverter and battery share the same Growatt software.

Pricing context and coverage

The company states that a turnkey installation in Spain ranges from 2,350 € to 12,512 € including VAT, and that a typical three-to-four-person household consuming 4,500 kWh per year would need a 5 kW system of 10-12 panels at around 6,452 €, recoverable in four to six years according to its own estimates. It notes that Plan MOVES III subsidies were active in 2026 in the Costa Blanca, Costa del Sol and Cataluña (up to 600 €/kWp), while the IRPF deduction (up to 40%) and the IBI rebate (25-50% over three to five years) apply nationwide with percentages set by each municipality. Prices are described as indicative for the Costa Blanca with average tariffs, with a logistics surcharge for projects in Madrid, Cataluña, Andalucía and the rest of Spain, and per-project quoting for commercial installations above 50 kW and for work in France, Portugal and Italy.

Multilingual service for international residents

The team and platform operate in eight languages: Spanish, English, German, Dutch, French, Russian, Ukrainian and Polish. The company presents this as particularly relevant for European residents on the Costa Blanca, a market it serves from its Altea base.
