Regulations

The Royal Decree for Self-consumption 244/2019, is approved in 2019 and regulates the technical and administrative aspects for the development of energy facilities for self-consumption.

The Royal Decree on Self-consumption aims to regulate aspects related to metering, grid connections and surplus compensation mechanisms for self-consumption facilities, as well as establishing a simple administrative self-consumption register.

-Self-consumption facilities without injection into the network (without surpluses) are those self-consumption facilities that cannot discharge surpluses into the network, so they must install an anti-discharge system. There will only be the consumer subject. In this case, the consumer must be the owner of the generation facility.

-Self-consumption facilities with surpluses (discharged into the network): They can discharge surpluses into the network. There will be the consumer subject and the producer subject. Depending on the treatment, it can be divided into:

• Self-consumption with surpluses accepted for compensation
• Self-consumption with surpluses NOT accepted for compensation

• Supports for installations with inclination: They have an inclination of 30º and are generally mounted on flat roofs.
• Supports for coplanar installations: They are installed directly on the roof and the panels on top. For sloping roofs.
• Solar trackers: They are used only for large solar farms, they follow the movement of the sun and orient the area of the modules perpendicularly to the sun.

Solar panel voltages:

• For applications with voltages of 24 volts or higher. They are the most common types of solar module.
• For applications with voltages of 12 volts. These 12-volt solar panels are usually small solar panels for very specific applications.
