The actual Spanish regulation (RD 244\/2019)<\/strong><\/a> allows that solar energy production can be used efficiently in the self-consumption mode<\/strong><\/a>. This regulation allows to self-consume solar energy within their own house. This opens the option of a significant reduction from the electricity bill<\/strong><\/a> amount. Obviously, anyone who is thinking deeply on that might be having some questions. In this post, we are describing how this excess of production is structured in a photovoltaic solar system.<\/p>\n

\"PanelesIn order to have the possibility to compensate the excess of the solar photovoltaic installation, it\u2019s mandatory to select the \u201ccompensation mode<\/strong><\/a>\u201d during the legalization process. Like that, during the periods of time when energy solar production is higher than consumption needs, the excess of energy will be exported to the electricity network and site owner will have the right to be financially compensated for that contribution by selling the energy to the user. Economical compensation will be done using the average price of the hourly electricity market minus deviations cost (for PVPC<\/a> consumers<\/strong>) or the agreed electricity price. On a later stage, some benefits can be applying like \u201cbono social<\/strong><\/a>\u201d, toll and taxes prices. Under any circumstances, the result of the compensation can be negative.<\/p>\n

How to get the right of economical compensation?<\/h2>\n

To get the right of economical compensation option, it\u2019s mandatory to meet the following requirements:<\/p>\n

    \n
  1. Primary energy source must be renewable<\/strong>. This is already the case since it\u2019s a photovoltaic solar system<\/strong><\/a>.<\/li>\n
  2. Installed power must be below 100kW<\/strong>. This is a very high value for residential users and typically any type of residential photovoltaic solar system will be below that value.<\/li>\n
  3. A unique contract between consumption and any potential auxiliary service linked. For domestic consumers<\/strong>, this is always the case.<\/li>\n
  4. In case the consumption and generation associated individual or entity is not the same<\/strong>, it is compulsory to formalize a compensation energy contract according to article 14 of the \u201cReal Decreto 244\/2019\u201d.<\/li>\n
  5. Solar installation can\u2019t be having any additional remuneration<\/strong>.<\/li>\n<\/ol>\n

    Considering that electrical invoices have some concepts that are not directly linked to the consumption or electrical generation, the typical savings linked to a self-consumption photovoltaic solar system in a domestic installation is between 50 and 75% depending on the particular details of each case. On the following tables compared examples of how both types of invoices can be are being shown:<\/p>\n
