At least in the Netherlands, you don't pay energy taxes on electricity generated "behind the meter", ie from solar panels on your own house. Electricity that comes from the grid, no matter how it is generated, comes with grid fees and energy tax. Seeing how the price for bulk electricity is currently ~0.09 EUR/KWh and the taxes+ grid charges come to ~0.15 EUR/KWh for a total price of 0.24 EUR/KWh, electricity from solar panels on your own house instantly becomes about 3x cheaper than if you put the same panels elsewhere in a field. Thus, many people opt to put the panels on their home since the installation cost is not that high and the financial benefits are substantial.
