Many Portuguese homes now have photovoltaic panels, battery storage, heat pumps and EV chargers. The insurance policy, however, may still describe a conventional house with standard electrical equipment.
That gap matters after fire, surge, storm, theft or accidental damage. If the equipment was not declared, valued or installed under compliant conditions, the claim can become slower and more contentious.
What needs to be declared
- Solar panels, inverters, mounting systems and monitoring equipment.
- Home batteries and their location, ventilation and installation certification.
- EV chargers, dedicated circuits and any shared condominium supply arrangements.
- Heat pumps, pool equipment and other high-value technical systems.
Why values are often wrong
Owners frequently insure the building based on old rebuild assumptions and add modern energy systems later. The result is underinsurance: the building sum, contents sum or equipment sub-limit may not be enough to replace what is now installed.
Questions before renewal
- Are panels covered for storm, hail, fire, theft and accidental damage?
- Does the policy include electrical surge and damage to inverters?
- Are batteries treated as building equipment or contents?
- Is third-party liability clear if equipment causes damage beyond your property?
Modernising a home should trigger an insurance review at the same time as the installation invoice is filed.
A worked example
An owner near Almancil installed a 6 kW photovoltaic array, a 10 kWh battery in the garage and a wall-mounted EV charger, at a total cost of roughly €21,000. The home policy was six years old and had not been touched. A surge during a summer storm took out the inverter and the charger’s control board — a replacement quote of €4,300.
The claim was accepted, and then capped. The policy carried a danos eléctricos sub-limit of €1,500 covering all electrical equipment in the property, and the panels themselves had never been added to the building sum insured. After the excess, the settlement was under €1,300 on a €4,300 loss. Nothing about that outcome was unfair; it was simply the policy the owner had bought, applied to equipment it had never been told about.
The number that decides most of these claims
Electrical damage — surge, short circuit, arcing, self-heating — is almost never covered at the full contents or building sum. It sits behind its own sub-limit, typically between €1,500 and €5,000 across the Portuguese market. Since an inverter alone can cost €1,500 to €3,000 and a battery considerably more, that single figure decides the outcome of most modern-installation claims. It is on your condições particulares, usually one line, and it is negotiable at renewal.
| Installation | Usually treated as | What to check |
|---|---|---|
| Roof-mounted panels | Part of the building | That the building sum insured was increased after installation |
| Ground-mounted array | Often excluded unless named | Whether it is inside the definition of the insured property at all |
| Inverter | Building equipment | The electrical damage sub-limit, not the building sum |
| Home battery | Varies — building or contents | Location, ventilation and whether a lithium exclusion applies |
| EV charger | Building equipment | Whether liability extends to a vehicle damaged while charging |
| Heat pump | Building equipment | Whether machinery breakdown is covered or only sudden external damage |
| Pool heat pump and plant | Frequently excluded | Whether outbuildings and plant rooms are within scope |
What is typically excluded
- Mechanical or electronic breakdown not caused by an insured peril. A panel that simply degrades, or an inverter that fails at year eight, is a warranty matter rather than an insurance one.
- Gradual loss of efficiency in panels or batteries.
- Faulty installation — and this is where the certification matters, below.
- Damage during installation, which belongs to the installer’s liability cover.
- Loss of feed-in income while the system is out of action, unless specifically added.
- Theft of ground-mounted panels where they were never listed as insured property.
Certification and the fire question
Insurers are increasingly attentive to lithium battery storage and EV charging, because both have caused high-severity fires elsewhere in Europe. In practice that means two things. Cover is normally conditional on installation by a qualified installer with the corresponding certification, and the insurer will ask for that certificate after a fire. Keep it, with the invoices, alongside your policy documents.
Where it goes wrong is the undeclared installation. If a fire originates in a battery or a charger the insurer knew nothing about, the argument is no longer about a sub-limit — it is about whether the risk accepted was materially different from the risk that existed. That can affect the whole claim, including the building, not merely the equipment. Declaring the installation typically costs €30 to €90 a year.
Liability: the part nobody thinks about
Two exposures worth a sentence each. A visitor’s vehicle damaged while charging at your property is a liability question, not a property one, and the standard retail liability limits are low. And if you export to the grid or supply a neighbouring property, you have moved slightly beyond a purely domestic use, which some wordings treat differently. Neither is difficult to cover; both are difficult to argue after the fact.
What the insurer asks at underwriting
- The installed capacity and total invoice value of the system, panels and inverter separately from the battery.
- Whether the installation was carried out by a certified installer and whether you hold the certificado de existência and the DGEG registration.
- Where the battery sits — garage, technical room, inside the dwelling — and how it is ventilated.
- Whether the electrical installation was inspected and certified after the work.
- For an EV charger, whether the circuit is dedicated and whether the supply is private or shared with a condominium.
The three mistakes we see repeatedly
- Treating the installation as a purchase rather than a change of risk. The invoice gets filed, the policy does not get updated, and the sums insured stay where they were.
- Assuming panels are covered because they are on the roof. They usually are, for storm and fire — but only up to a building sum that has not moved since 2019.
- Ignoring certification. An uncertified installation that causes a fire gives the insurer a direct argument on causation, and a non-disclosure argument on top of it.
What to do
Send us the installation invoices and the certification. We will tell you what your current policy would pay on each item and what it costs to fix the gap — usually a small endorsement rather than a new policy. Our clause-by-clause guide to the Portuguese multi-risk wording explains why outdoor property and plant are treated so restrictively in the first place.
What it costs to fix
Adding a declared photovoltaic system to an existing building sum insured is rarely a new policy and rarely expensive. On a typical Algarve villa, raising the building sum by €20,000 to absorb the installation adds something in the order of €15 to €35 a year. Lifting the electrical damage sub-limit from €1,500 to €5,000, which is the change that actually alters claim outcomes, generally costs between €20 and €60. A separately scheduled battery, where the insurer treats lithium storage as its own item, is priced individually but is usually under €100.
Set against a €21,000 installation, those are not meaningful numbers. The reason they go unpaid is not cost; it is that nobody tells the owner the sub-limit exists until the inverter has already failed.
