On the contrary, the Grand Duchy remains one of the most favourable countries in which to produce your own solar-generated electricity. A recent article published by Paperjam confirms this: the Luxembourg environment is still ideal for making a quick return on your installation.
Here are 3 good reasons why Luxembourg clearly stands out from its neighbours.
It's a fact: the subsidies on offer in Luxembourg are among the most advantageous in the Greater Region.
Whether you own a house or are a representative of an apartment block, the financial assistance offered by the State can cover a significant proportion of your initial investment. The result: a rapid and predictable return on your investment.
And that's not all: Luxembourg is making a long-term commitment to the energy transition. At a time when some neighbouring countries are gradually reducing their financial support, the Grand Duchy is maintaining a clear, stable and ambitious policy, with a clear commitment to developing renewable energies.
Another advantage specific to Luxembourg is that the price of electricity is relatively high. This may seem negative at first sight... but for solar electricity producers, it's excellent news!
Every kilowatt-hour you produce yourself saves you more money, which directly increases the profitability of your installation.
In comparison, some border countries apply capped or regulated tariffs, which limits the potential gains for households equipped with solar panels.
Luxembourg not only offers attractive incentives and profitability, but also a stable regulatory framework, which is essential if you want to invest with confidence.
There are no sudden changes in direction, no legislative uncertainties like we see elsewhere: here you have real long-term visibility.
When it comes to profitability, the figures speak for themselves: according to Paperjam, an installation generally pays for itself in 7 to 10 years, while it can produce electricity for 25 to 30 years. This represents up to two decades of free production - a rare achievement in today's energy sector.
