Med faste afregningspriser er netoperatørerne forpligtet til at købe solenergi til priser, der sikrer, at solenergiproducenter (sædvanligvis ejerne af solcelleanlæg) får dækket deres omkostninger og kan opnå et rimeligt afkast.
By means of FITs grid operators are bound to buy solar energy at prices which ensure that solar energy producers (usually the owners of the solar installations) recover their costs and earn reasonable rates of return.
