It should be borne in mind that photovoltaic panel installations are subject to different VAT rates depending on the type of installation and the type of customer. First of all, it is complicated to apply a reduced VAT in an existing photovoltaic installation. 

However, it should be remembered that in fraudulent cases of inspection, the Agencia Estatal de la Administración Tributaria will oblige both the end customer and the contractor to contribute the VAT avoided and to pay a significant financial penalty.
