Connected to your existing power supply an Autoconsumo or Zero Feed in (Grid Connected) solar installation can significantly reduce your electricity usage thereby reducing your power costs.
In line with current legislation it is generally illegal to connect a solar system to the grid(Electrical Mains Supply) if the Solar system is able to feed power into the grid unless it is properly certified as meeting electrical installation standards and is registered with the relevant authorities. This legislation also provides for prosecution with fairly harsh financial penalties for unauthorised connections.
It is still possible to connect to and feed power to the grid from a Solar System providing a strict set of acceptance criteria has been met, this will include but is not limited to obtaining relevant Planning permissions, Installation and connection certification and that the installation is controlled and set up to meet the requirements of RD900/15 ( Royal Decree). The Solar industry has developed Solar electric systems specifically to allow private householders and small producers to install systems that comply with this requirement.
Known as Autoconsumo or Grid Zero these types of system control or do not feed any power back to the grid thereby complying with current requirements. Grid Zero,effectively any Solar power produced by the Solar collectors is prioritised for the use of the household, in the event of there being no requirement for power the Solar Inverter controller shuts down the Solar charge regulator preventing any power being fed back to the grid.
The second type of system is called Autoconsumo, this is a system that again provides Solar power for home use, but in the event of excess power this is fed back to the grid, however at this time it should be noted that this power can be charged for by the utility company ( IE you could pay for all solar power fed to the grid!! and this charge would be at he standard rate!!!). It is important that your solar power installation matches your power consumption to prevent excess costs and a new contract is agreed with your power supplier.
Both of the above systems require the fitting of an independent certified electricity meter to monitor the amount of solar power produced , and in time it is the intention by the government for the amount of solar Power produced to be taxed at the set rate.
Please note that it is the owners responsibility to ensure that the installation meets legal demands and is registered with the Local power company, The Local authority and is registered on the Ministry of Interior log of Grid connected solar systems. Your Solar Supplier should supply you with a Boletin de Electicidad on completion of installation to allow you to register your system correctly.
Solar Sky currently can offer a specialist adviser to register systems with the relevant authorities ( subject to certification of system). NB this service is chargeable.
