This includes official information on the origin of the energy consumed during the previous year, its impact on the environment and information on the source of publication.

16. Solar panels: How does this appear on your electricity bill?

If you have solar panels installed, part of the energy you consume comes from them and means a significant saving on your bill. If you do not yet have solar panels, please allow us to assess you.

If you have solar panels, on your bill you will see a section entitled "Compensation for surpluses". There you will see the energy that your solar panel installation has transferred to the electricity grid. You will receive financial compensation for this energy and your bill will be lower.  

Spanish regulations have established a maximum for the compensation of surpluses, so that, for a billing period, it will not be possible to pay compensation for surpluses for an amount that is higher than the cost of the energy you consume from the grid. Whenever this issue affects you on any invoice, it will appear as "Adjustment for limits to compensation".
