Until recently, Spain had a very general self-consumption policy framework that applied to both grid-connected and off-grid systems. This month though, Spain’s Council of Ministers approved a new self-consumption law that has set the country’s solar advocates up in arms with the government.
The main problem with the new law, say solar advocates, is that it taxes self-consumption PV installations even for the electricity they produce for their own use and don’t feed into the grid. Spain’s PV sector calls the new law a ‘sun tax.’
According to Spain’s Photovoltaic Union (UNEF), the new law requires self-consumption PV system owners to pay the same grid fees that all electricity consumers in Spain pay, plus a so-called ‘sun tax’. Specifically, said UNEF, a self-consumption PV owner "will pay a ‘sun tax’ for the whole power [capacity] installed (the power that you contracted to your electricity company, plus the power from your PV installation) and also another [second] ‘sun tax’ for the electricity that you generate and self-consume from your own PV installation (this applies to installations larger than 10 kW)."
