Solar Incentives in Denmark

The Danish Håndværkerfradrag (craftsman deduction) is a personal income tax deduction for labour costs on home improvement and energy-efficiency works. As of 2026, the annual ceiling is DKK 8,600 per person (~€1,150) on green-energy works including solar PV installation, heat pumps, insulation, and battery storage. Spouses each have a separate ceiling, doubling the household total. Equipment cost is NOT covered (only labour). The deduction is claimed on the annual personal income tax return by submitting the labour invoice details through the Skat (Danish Tax Agency) e-portal. The installer must register the work in Skat's reporting system. This deduction is the primary national-level financial support for Danish residential solar in 2026.

Denmark's hourly net-settlement applies to residential and commercial solar PV registered after April 2012 under Gruppe 6 hourly settlement rules. Settlement occurs in 15-minute or hourly intervals: when generation exceeds consumption in an hour, surplus is exported and compensated at the Nord Pool DK spot market price for that hour. Negative pricing periods (Denmark sees 50–200 negative-priced hours per year, primarily summer afternoons) mean some exports incur small charges rather than payments. The hourly settlement structure penalizes systems with poor self-consumption and rewards storage-attached systems that shift export to higher-price evening hours. Battery storage payback economics in Denmark are accelerated by the wide spread between low-export-hour prices and high-import-hour retail rates.

Denmark applies the standard 25% Moms (VAT) to residential solar PV equipment and installation. There is no general residential PV exemption. Microproducers selling small amounts of surplus electricity may fall below VAT registration thresholds and avoid VAT on the export-revenue side, but the equipment purchase remains taxed at 25%. Combined with the Håndværkerfradrag (labour deduction) and the high retail electricity rate (€0.41/kWh — among the highest in the EU), Danish residential PV economics are workable despite the lack of equipment-side tax breaks.
