Am I allowed to install solar panels without a permit in Sweden?
Usually yes — solar panels that follow the building's form need no building permit. Since 2018, roof- and facade-mounted panels fitted flush along the roof or facade are permit-exempt under the Planning and Building Act ch. 9 §3c, unless a permit is needed for other reasons. Angled-up or angled-out panels do need a permit. The municipality can also reinstate the permit requirement in the detailed plan. For the installation you get the green-tech credit: 20% on solar panels (and 50% on battery and charging point), up to 50,000 kr per person per year.
