Grön teknik (green technology reduction)
Grön teknik (green technology) is a tax reduction for installing solar panels, a home battery for self-produced electricity, and an EV charging point. Like ROT and RUT you get the reduction directly on the invoice, so you pay a lower amount to the company.
Rates and cap
The reduction is 15% of the cost for solar panels and 50% for a battery or a charging point. It is calculated on both labour and materials, unlike ROT and RUT which count only the labour cost. The cap is 50 000 kr per person per year. The solar rate was lowered from 20% to 15% during 2025.
How it differs from ROT
Green technology has its own cap, separate from the ROT and RUT cap, and it also counts the material cost. It also sits last in the statutory order in which tax reductions are applied: first jobbskatteavdrag and the others, then ROT and RUT, and after that green technology. The order matters if your tax is not enough for all the reductions.
When the reduction does not fit
Because the reduction is paid out in advance through the invoice model, your final tax assessment checks whether your final tax is enough for the whole amount. If it is not, you have to pay the excess back as kvarskatt (residual tax). An unused reduction cannot be carried to next year.
Micro-production of electricity as a separate tax reduction was abolished from 2026. The green-technology reduction for the installation itself remains.
