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).

For Jyväskylä, a system tilted 40° and facing south yields about 821 kWh/kWp a year, varying by roughly ±53 kWh/kWp between years (PVGIS 5.3 (EC JRC), 3 September 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).
