Solar Incentives in Sweden

Sweden's Gröna Avdraget (Green Deduction) replaced the earlier solar PV grant scheme effective January 2021. The deduction operates similarly to the well-known ROT (renovation) and RUT (cleaning) deductions: the installer applies the reduction at the point of invoice and recovers it from Skatteverket (Swedish Tax Agency). For solar PV: 20% of labour cost is deductible, capped at SEK 50,000 per person annually (couples may each claim, doubling the household ceiling). For battery storage: 50% of labour cost up to SEK 50,000 per person — significantly more generous than for PV alone, reflecting policy emphasis on storage uptake. Equipment cost is NOT covered (only labour). The customer's preliminary tax (preliminärskatt) must be sufficient to absorb the deduction; non-taxpayers cannot benefit. The customer pays the post-deduction amount; the installer claims the residual from Skatteverket.

Microgenerators with grid connection capacity ≤ 100 A receive a tax reduction of SEK 0.60/kWh (~€0.054/kWh) on net exported electricity. The customer must purchase at least as much as they export over the year (the reduction is for net export equal to net import, mirrored). The reduction is applied automatically on the personal income tax return based on data the local distributor reports to Skatteverket. In addition to this tax reduction, the customer receives a market price for exports from their electricity retailer (Vattenfall, E.ON, Fortum, etc.) — typical 2026 export rates SEK 0.30–0.80/kWh varying with the spot market. Combined market-price + tax-reduction value: approximately SEK 0.90–1.40/kWh net per exported unit (~€0.08–€0.13).

Under Swedish VAT rules (Mervärdesskattelagen), a microproducer of solar electricity is exempt from VAT registration if their annual revenue from grid sales is ≤ SEK 80,000. This means residential prosumers do not need to charge or remit VAT on self-consumed electricity, simplifying tax treatment. Residential PV installations rarely exceed this threshold — a 10 kWp system in Sweden typically exports 4,000–5,000 kWh/year worth SEK 4,000–7,000 in market value, well below the SEK 80,000 ceiling. Larger commercial systems must register for VAT and apply standard rates. The exemption is automatic for qualifying microproducers; no special filing required.

Sweden does not provide a residential VAT exemption on solar PV equipment as some other EU countries do. The standard 25% Moms applies to PV modules, inverters, mounting hardware, and battery storage. The Gröna Avdraget reduces labour cost (20% PV / 50% battery) which somewhat offsets the high VAT, but equipment remains at full rate. For a typical SEK 150,000 residential PV install (€13,500), VAT contributes approximately SEK 30,000 (€2,700) on equipment alone.
