Grid-connected photovoltaic self-consumption system

The photovoltaic self-consumption system means that your company can generate the energy that it needs by setting up solar panels. One of the most worthwhile forms of producing energy is the grid-connected PV self-consumption system.

Grid-connected self-consumption

to the electric system

It is compatible with all types of companies. It is interesting because it allows the use of all the functionalities of the network and of the photovoltaic installation in a continuous and complementary manner.

Benefits of a grid-connected photovoltaic self-consumption system.

 ◾️ The most practical option that is compatible with all kinds of companies.◾️ All the features of the grid connection and the photovoltaic system can be used continually and they can complement each other.◾️ You save money on electricity bills right from the start.◾️ Your company becomes a clean energy generator.


We have grid-connected systems that inject surpluses back into the grid and zero injection systems.

  • What is it?


    These are systems that are connected to the consumer’s own internal autonomous consumption network, and they are also connected to the power grid network with a physical electrical connection.

    Energy does not have to be stored for this type of system because the electricity from the grid is used when the energy production of the photovoltaic panels is low.
    This type of self-consumption is governed by the Spanish Royal Decree 900/2015, which establishes the administrative, electrical and economic conditions of the different types of electrical energy supply and production.

  • Benefits


    The generation of electricity depended entirely on the electrical companies and only off-grid homes and companies could use the power that they produced with the PV self-consumption systems. Later, the liberalization of the energy market meant that anyone could produce electricity, but they could only sell it to the power grid network, they could not use it to be self-sufficient. However, at the end of 2011, Spain passed a Royal Decree that allowed self-consumption and this built up enormous expectations.

    We will explain the most significant benefits of grid-connected self-consumption for any company:

    1. Self-consumption means direct savings, because the company is self-sufficient by directly using the energy produced by the photovoltaic system, whose kWh can be as much as 80% cheaper than what is supplied by the grid. A grid-connected photovoltaic system for self-consumption enables a company to linearize the cost of the kWh during the service life of the system (approximately 30 years); this prevents the abusive electric power distribution companies from constantly increasing the prices of electricity. So, it will always be more cost-effective to produce your own energy than buying it from the electricity distribution companies (this has been confirmed by the Spanish Institute for Diversification and the Saving of Energy).

    2. Energy loss when transmitting electricity is prevented. When electricity is distributed and transmitted 10% of it is currently lost; this stands for 2000 million euros a year.

    3. The third benefit is associated with the use of clean technology to generate this type of energy, which cuts down on the use of fossil fuels and the need to depend on electricity produced in other countries.

    Solar energy is the best way to generate electricity used for self-consumption in companies for different reasons:

    1. Technology is very mature; a photovoltaic system is set up and started easily. The solar panels can be connected directly to the company’s own grid

    2. The prices have dropped; solar panels have become much cheaper in the last few years.

    3. Electricity is produced during the day, which is when more is consumed and it is when the power supplied from the grid is the most expensive.

    4. The technology and the quality of the parts of a system have increased the service life of the systems; they also increase the energy production and the efficiency of these systems.

    En España, el Real Decreto 1699/2011 que regula la conexión a la red de las instalaciones de producción de energía de pequeña potencia hizo un hueco a todas aquellas empresas que quieran sacar partido a una forma de generación de energía eléctrica cuya materia prima no tiene ningún coste.
