Self-Consumption Surpluses: sell the solar energy you have left over

The idea behind self-consumption is simple: you generate your own energy and then use it. But what happens when you generate more energy than you need? Can you "make money" from this surplus?

More and more people are deciding to take up self-consumption and install solar panels to generate their own energy.

The idea is simple: you generate your own energy and then use it.

But what happens when you generate more energy than you need?

 

Your surplus energy can help you save on your bill

One of the questions newcomers to self-consumption most frequently ask is: how can I sell my excess power to the grid to help me save on my electricity bill?

There are two important options for your surplus energy:

  1. With simplified compensation for surpluses: fast and simple. You save because the surpluses are credited on your bill. You only have to meet the established conditions and contract a solar energy tariff. Each month you will be credited on your bill for the value of the surpluses (they are not subject to taxes), taking into account the limit set by the regulation, which establishes that in each invoice the economic value of the surplus energy may not be higher than the economic value of the cost of the energy consumed from the grid. You will be able to save on the energy term in your bill. Here, we will explain the sections on your bill to help you fully understand your electricity bill.
  2. Without compensation: here we are not talking about saving but rather about selling energy to the electricity market. To do this, you need to register as an energy producer, a complex procedure of little interest for most domestic self-consumers. 

 

Simplified compensation for surpluses

This is the option we recommend, the most common choice for electricity self-consumption users to save money through the surplus energy from their solar panel installation.

The process is quick and simple, just 4 steps:

  1. Contract the installation of photovoltaic solar panels.
  2. Legally register the installation with the appropriate regional authority: this is where you inform the regional authorities that you would like to benefit from simplified compensation for surpluses.
  3. The Regional Authority will send the details of your photovoltaic installation to the electrical distributor in the area, and they will then inform your electricity retailer. If this is not clear to you, here we will explain the differences between the distributor and the retailer.
  4. Your retailer will send you a letter to verify that your installation details are correct, in which case, you will only have to call Customer Services free of charge (800 760 909) and contract a tariff that includes compensation for surplus energy. For example, Tempo Solar.

If you choose self-consumption with Endesa, these 4 steps are simplified and become one. You will not have to worry about a single procedure because we will take care of everything from installing the panels to obtaining the permits and sending all the documentation.

How to view surpluses on your bill

Throughout the month, your photovoltaic installation may actually produce more energy than you use. What happens in that situation is that the surplus energy is transferred to the distribution network. You get financial compensation for these surpluses.

Here is an example of how surplus compensation appears on your bill:

Current regulations also explain why the price at which you sell your surplus energy is lower than the price at which you pay for the energy you consume from the grid. The access tariff for the electricity grid and the cost of producing electricity are the reason for this price difference.

 

Take advantage of the tax benefits

Currently, virtually all city councils offer discounts on municipal taxes for the installation of solar panels.

Sometimes this discount may include a 50% reduction on property tax (IBI) for 10 years.
