The Council of Ministers of Spain has approved the controversial solar power tax on October 9, 2015. Tax will be imposed on the self-supply of electricity generated by privately owned solar panels.

The tax will be introduced in the next six months and apply to solar power systems with a capacity of over 10 kilowatts. The Spanish islands will be exempt from this solar power tax. The purpose of this tax is to ensure that solar panel users contribute to the cost of maintaining the country’s electrical grid, as they use it as a backup supply.
