The zero VAT rate under § 12 (3) UStG applies only to deliveries to Germany. Current delivery address: Germany.
Since 1 January 2023 a VAT rate of 0 % applies to certain photovoltaic products.
Up to 30 kWp no proof is required. The conditions are deemed met if the installed gross capacity of the system according to the Marktstammdatenregister does not and will not exceed 30 kilowatts (peak).
If the goods are not bought for a photovoltaic system — for camping, travel or resale, for example — the regular rate applies. Choose 19 % VAT in that case.
Should the conditions not have been met despite your confirmation, the statutory VAT may be charged afterwards.
