Malta · 2026 REWS Grant

How much could solar save you?

By Ian Grima Mahoney · Updated May 2026

Models the 2026 REWS grant scheme — Option A (PV with hybrid inverter) and the optional Option C battery grant. Updated April 2026.

Solar economics in Malta hinge on three things most calculators skip: the REWS 2026 grant (€645 per kWp on panels capped at €3,000, plus €600 per kWh on batteries capped at €6,000), the ARMS 5-band tiered residential tariff — heavy users save €0.30+ per displaced kWh while light users save closer to €0.13 — and the fixed 10c5/kWh feed-in tariff for 20 years on energy you export. The calculator combines all three plus the +5% NZIA bonus on EU-aligned equipment into one payback number.

Look at a typical bimonthly ARMS bill, divide by 2. The calculator uses your bill to derive your annual consumption from the ARMS tariff bands and computes the effective per-kWh rate solar self-consumption actually displaces — heavier users save more per kWh.
Pick whichever you know. The calculator converts between them at ~0.18 kWp per m² (modern panels).

Frequently asked questions

How is the 2026 REWS solar grant calculated?

Two grants, applied for separately. The PV grant pays €645 per kWp of installed solar, capped at €3,000 per system (roughly 4.65 kWp). The storage grant pays €600 per kWh of battery, capped at €6,000 per system (roughly 10 kWh).

You get one approval letter for the PV + inverter and a second for the battery. NZIA-compliant equipment earns a +5% bonus applied after the cap, so a maxed-out €3,000 PV grant becomes €3,150.

Option A, B, or C — which one applies to me?

The 2026 REWS scheme has three options:

  • Option A: new PV install with hybrid inverter — 65% of eligible cost, max €3,000/system or €645/kWp.
  • Option B: retrofit for existing PV connected to the grid for at least 6 years — adds a hybrid inverter (75%, max €1,800 or €350/kWp) and a battery (75%, max €6,000 or €600/kWh). No grant on new panels under Option B.
  • Option C: battery storage only — 75% of eligible cost, max €6,000/system or €600/kWh. Stacks on top of Option A when you fit a battery alongside a new PV system.

All three earn a +5% NZIA bonus on NZIA-compliant equipment.

If you've never had solar, Option A — plus Option C if you also want a battery. If you have an old system whose initial feed-in contract is winding down, Option B unlocks self-consumption gains via storage.

Can I combine Option A and Option C in the same application?

Yes — the 2026 REWS leaflet specifically calls out the combined A+C pathway: an individual applying for a PV system with hybrid inverter (Option A) may also simultaneously apply for a battery-storage-only grant (Option C).

The two grants are filed separately and each has its own per-system / per-unit caps, but both apply to the same household installation. NZIA bonuses (+5%) apply independently to the equipment in each option.

The calculator above already models this stacking when you enter a non-zero battery size on the new-install tab — the displayed grant total combines Option A on the panels and Option C on the battery.

What is the NZIA bonus and which equipment qualifies?

NZIA is the EU's Net-Zero Industry Act, which favours EU-aligned manufacturing of clean-energy hardware. Qualifying PV modules, inverters, and batteries earn +5% on top of your (capped) REWS grant.

Confirm a specific product's NZIA status with your installer before signing — most Maltese installers carry at least one NZIA-eligible inverter line specifically because of the bonus.

How does the Maltese feed-in tariff (FIT) interact with self-consumption?

Energy you use yourself displaces grid imports at your residential ARMS tariff. ARMS is a 5-band tiered annual tariff (€0.1047/kWh in Band 1, rising to €0.6076/kWh in Band 5), so the rate you save depends on your annual consumption. The calculator reverse-engineers your annual kWh from your monthly bill and computes the effective per-kWh rate over the bands your displacement actually walks down — heavy users (Bands 4–5) typically save €0.30+ per displaced kWh, while light users (Band 2) save closer to €0.13.

Energy you export to the grid is paid the feed-in tariff: 10c5 per kWh (€0.105) for 20 years, fixed in the FIT election letter at the time of grid connection.

For most households, self-consumed energy is worth more than exported energy, so a battery still helps — every kWh you'd otherwise export and now consume is worth the difference between your effective ARMS rate and the 10c5 FIT. The case is strongest for heavy users in the upper bands.

What is a typical payback period for residential solar in Malta?

With the 2026 grant and the 10c5/kWh FIT for 20 years, a 4–6 kWp residential system typically pays back in 5–8 years and delivers a 25-year net benefit of €8,000–€20,000+ depending on consumption pattern, roof orientation, and shading.

Adding a battery extends payback to 7–10 years but compounds bill savings each year by raising self-consumption. Run the calculator above with your actual electricity bill and roof for a personalised number.
