Charging an electric car from solar in Malta

The band jump is the whole story

Enemalta's residential tariff, published 6 February 2026 and inclusive of 5% VAT, is banded and the bands are cumulative over the year. They are not monthly, and they do not reset when the bill arrives:

There is also a service charge of €65/yr on a single-phase supply and €195/yr on a triple-phase supply, and an eco-reduction for small households.

The step from €0.1607 to €0.3420 is a 113% increase in the marginal rate. Nothing else on the tariff comes close, except the step above 20,000 kWh. An electric car does not get its own meter in anything our sources establish — its kWh accumulate in the same annual total as the air conditioning and the water heater. So the question "what does charging the car cost?" has no single answer. It costs whatever band those kWh happen to land in.

A household running 10,000 kWh/yr currently pays €1,371.40 for energy before the service charge. Add 4,000 kWh of car charging drawn from the grid and the bill rises by €1,368.00, because every one of those kWh is billed at €0.3420. The first 10,000 kWh cost €1,371.40; the next 4,000 cost almost exactly the same again.

We have not found a published figure for typical EV annual consumption in Malta, so 4,000 kWh here is an arithmetic illustration, not a claim about your car. Substitute your own number — the logic does not change.

Why daytime charging beats exporting, and when it doesn't

Under the scheme reported on 16 April 2026, the grant-free feed-in tariff is €0.15/kWh for 20 years for systems under 40 kWp, with an 8 MWp allocation for 2026 and a total budget of €15.3m (€4.1m PV, €11.2m batteries). The scheme opened on 20 Apr 2026, with a 5% uplift for NZIA-compliant kit.

So every kWh your roof produces is worth either €0.15 (exported) or whatever band you would otherwise have bought it in (self-consumed). That gives a clean comparison:

Two honest conclusions follow.

First, if your household stays under 6,000 kWh/yr, exporting is worth more than self-consuming, by a couple of cents a kWh. A small flat with a small array and no car is better off selling what it makes. Nobody selling solar says this, but the two published rates say it plainly.

Second, once an EV pushes your annual total past 10,000 kWh, the arithmetic inverts hard. In our 4,000 kWh example, charging entirely from the roof in daylight avoids €1,368.00 of import. Exporting those same 4,000 kWh and charging from the grid at night earns €600.00 and still costs €1,368.00. The gap is €768.00 a year, from the same panels, decided purely by when the car is plugged in.

That is the practical point of this article. An EV in a Maltese household is usually the thing that drags the annual total over 10,000 kWh, and it is also the one large load whose timing you genuinely control.

What a given array actually produces

PVGIS v5.3 (SARAH3 database, 14% system losses), run for Malta on 16 October 2026:

To cover 4,000 kWh of generation you need roughly 2.4 kWp facing south at 32°, 2.7 kWp flat, or 2.9 kWp facing east or west. Gozo is marginally better than Malta, at 1,677 kWh/kWp.

Note the word generation. Those kWh only displace €0.3420 import if the car is drawing them at the moment they are made. A car that leaves at seven and returns at six is not charging from the roof on a weekday — it is charging from the grid while the roof exports at €0.15. An east-facing array loses 17% of annual yield but produces it earlier in the day, which may suit a car that is home in the morning; a west array loses 16% and shifts output later. Which matters more than the headline yield depends on your week, and no source establishes a typical Maltese self-consumption fraction.

Where a battery fits

A battery does one thing to this arithmetic: it moves a kWh from the export column to the avoided-import column. Its value per cycled kWh is therefore exactly the difference in the table above — €0.0107 if your annual total sits in the 6,001–10,000 kWh band, €0.1920 in the 10,001–20,000 band, €0.4576 above that. At €0.0107/kWh a battery is not going to pay for anything. At €0.1920 the case is arguable. We have no neutral published Malta battery price to put against it, so we are not going to pretend to a payback figure; the method is set out in StoreYourSolar and the battery tab of the calculator.

Grants, permits and the Maltese practicalities

The 2026 REWS RES grant closed to applications on 12 September 2026, and the battery options closed earlier, on 13 July 2026. A further round has been announced but not detailed — no terms, no budget, no opening date. The grant-assisted feed-in tariff was €0.105/kWh in 2025 and the 2026 rate is unconfirmed. The grant-free route and its €0.15/kWh for 20 years is what is actually documented today.

Rooftop PV is permitted development under DNO Class 1(iv), S.L. 552.08, provided the installation is DC15-compliant. No separate environmental permit is involved.

Two local constraints worth stating before you plan anything. If you are in an apartment, the roof is usually common property and condominium rules bind the works — that applies to the panels and to anything you want to run down to a parking space. And in Gozo, every delivery crosses on the ferry, which shows up in lead times more than in yields — PVGIS puts Gozo's optimum at 1,677 kWh/kWp, slightly ahead of Malta.

One tariff detail to check before you commit to a charger: if the installation moves you from a single-phase to a triple-phase supply, the standing service charge goes from €65/yr to €195/yr. That is €130/yr regardless of how much you use.

What we could not find: any published figure for typical EV annual consumption in Malta, and any published installed price for a home charger here. Both are listed as gaps above rather than filled with a guess. If you want the roof side measured properly first, there is a free roof survey, and our installers are verified through CheckYourSolar.
