Is solar worth it in Tossa de Mar?
Tossa de Mar's houses climb the hillsides above the old town and the coves of Cala Pola and Llorell, most built as holiday homes with clear, unshaded roofs facing the Mediterranean. PVGIS puts annual irradiation at 1,907 kWh/m² here, giving a specific yield of 1,499 kWh per installed kWp and a typical payback of around 4.1–5.8 years for a well-sized villa system.

Why Tossa de Mar suits solar — for a holiday home
Tossa de Mar is predominantly a second-home market: hillside villas above the bay, occupied mainly through summer, with roofs that catch sun uninterrupted for most of the day thanks to the steep terrain giving them clear sightlines to the sea. That occupancy pattern shifts the economics — a larger share of the return comes from exported surplus credited under compensación de excedentes across the months the house is empty, rather than from same-day self-consumption.
25.7% of Tossa de Mar's 6,347 residents are foreign-born, and with an average income of about €14,852 per resident, owners here are used to managing a Spanish property remotely between visits. ENERA's monitoring app lets you track production from anywhere, and we run the whole project — design, installation and paperwork — in your own language.
What does a solar installation cost in Tossa de Mar?
A typical Tossa de Mar villa takes a 6–10 kW system, priced between €5,300 and €8,300 fully installed — panels, inverter, mounting, labour, legalisation and VAT all included in one fixed, itemised quote. Hillside plots with steeper access above Cala Pola and Llorell can add scaffolding time, which ENERA factors into the quote up front. Pitched tiled roofs typical of the old town and surrounding hillside take corrosion-resistant hooks that don't crack a single tile.
Solar incentives and tax breaks in Tossa de Mar
We checked Tossa de Mar's current IBI property-tax ordinance in full and found no solar bonification in it today. Tossa de Mar's ICIO construction-tax ordinance does carry a solar clause, but a modification was provisionally approved by the Ple in March 2026 and its published text wasn't available when we checked, so the current rate isn't safe to quote — ENERA confirms the live figure with the ajuntament before you apply.
Catalunya does not currently offer a regional IRPF income-tax deduction for solar — we checked the Agencia Tributaria's full list of Catalan autonomic deductions and none covers renewables or self-consumption. ENERA stays on top of Tossa de Mar's ordinance changes and tells you honestly what applies to your property rather than quoting a figure we can't confirm.
How much can you save on electricity in Tossa de Mar?
With Spanish grid electricity around €0.19 per kWh, a well-sized system in Tossa de Mar can cut a household's annual bill by roughly €1,120–1,600 — though for a part-time holiday home, more of that value arrives as exported surplus credited under compensación de excedentes than as direct daytime saving, since the property sits empty for long stretches of the year. At Tossa de Mar's irradiation levels, payback on a typical installation lands around 4.1–5.8 years, with 20-plus years of production left after that. These are estimates: every quote we send includes a projection built around how you actually use the property.
How your installation works, start to finish
ENERA runs the whole project as a single turnkey service. We start with a remote design from satellite imagery and a recent electricity bill, sizing the system to your real (or projected) consumption and sending a fixed, itemised quote — no site visit needed for a firm number. If you go ahead, installation on a typical Tossa de Mar villa takes one to two days on the roof. In parallel we prepare and submit every document: the technical memoria, the electrical certificate (butlletí), RAC registration for the grid connection and compensación de excedentes agreement, plus the works notification with Tossa de Mar's ajuntament. You sign; we file — manageable remotely if you're not on-site for the works.
