Household tax credit: 35% of the labour share of a company invoice, up to €1,600 per person per year, with a €150 own share (Verohallinto, 10 February 2026). The government has proposed raising this to 40% and €2,100 for 2026–2027, retroactively from 1 January 2026 (HE 113/2026 vp, Eduskunta, 11 June 2026). Parliament has not passed the bill, and the tax administration still writes about it in the conditional (Verohallinto, 16 June 2026).

Across Finland the range is 776–940 kWh/kWp, and it is not a clean north-south gradient: coastal Oulu out-yields inland Tampere and Jyväskylä, because cloud climatology matters more than latitude (PVGIS 5.3 (EC JRC), 3 September 2026). What decides the payback is not the yield but how much of it you use yourself: in a detached house that is 50–80% (Motiva, 30 December 2025).
