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? You can save even more, thanks to the 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?
One of the questions people taking up self-consumption most frequently ask is: How can I sell my surplus solar energy to help me save on my electricity bill?
There are two significant options for your surplus energy:
This is the option we recommend, the most common choice for electricity self-consumption users to save money with the surplus energy from their solar panel installation.
Here, we will explain the different sections in your invoice to help you fully understand your electricity bill.
The Solar Simply with virtual battery tariff is Endesa's option that enables you to compensate the surpluses you generate in your bill at a price of €0.10.
Now the virtual battery enables you not to lose the amount that exceeds the limit for compensation. This uncompensated amount will be accumulated in the form of a balance in the virtual battery and will be applied as a means of payment in the total to be paid on the following bills.
If you do not accumulate any surplus during the month there is no problem. This means that you have made good use of the energy generated by your panels and the little you have been able to inject into the network has been compensated at a very competitive price. The accumulated amount will depend on the consumption made, the production from the solar panel and the balance between surpluses and energy consumed from the grid. If there is any outstanding debt, the amount from the virtual battery would be used to offset this debt.
If you are interested in surplus compensation, the process to join is quick and simple, in just four steps:
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.
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.
The amount of these savings depends on the kWh fed into the grid, and the compensation price agreed in your tariff. In the calculation of remuneration for surpluses, there is a regulated "limit for compensation", which means that you cannot be financially compensated with an amount that exceeds the kWh you have consumed from the grid.
The remuneration will be included in each invoicing cycle.
The remuneration will appear in the form of a discount, which will mean savings on your electricity bill.
You will find the amount in your electricity bill under "Other items".
This will depend on the option you choose:
