The maximum refund for surplus energy is what you should pay for consumption
Someone with a self-consumption installation may wonder: if one month I generate more energy than I use from the electricity grid, does the bill include receivables?
Throughout the month, your photovoltaic installation may produce more energy than you use. In this situation, the surplus energy is injected into the distribution grid.
Current regulation sets an important limit for these surpluses: an amount greater than the amount billed for electricity use during the same month cannot be refunded in euros.
That is, the maximum value that a company can compensate you for for your surplus energy is the value of the monthly power unit price billed. If you spend €65 in energy in one month: this is as much as you may be compensated for for your surplus injected into the grid.
Your bill will never include receivables, but it may be zero euros to pay for the variable component (consumption). You still need to pay the fixed component (power).

Current regulation also explains why the price at which you sell your surplus energy is less than the price at which you pay the energy you consume from the grid. The grid access tariff and the cost of producing electricity are behind this price difference.
Leverage 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 of property tax (IBI) for 10 years.
