ETS2 in Belgium: Why Solar Panels Are the Best Protection Against Rising Energy Costs

Starting in 2027, the European Union will launch ETS2 (Emission Trading System 2), an extension of the current carbon market. This system requires suppliers of gas, heating oil, and fuels to purchase CO₂ allowances for every ton emitted.
The result? The energy bills of Belgian households will inevitably rise, as these costs will be passed on to consumers.

The good news? Installing solar panels in Belgium is becoming the best protection against rising energy costs. Profitable, sustainable, and ecological, solar power is the smartest investment for the future.

What Is ETS2 and How Will It Impact Belgian Households?

The goal of ETS2 is to reduce the use of fossil fuels across Europe. In Belgium, where many families still heat with gas or oil, the impact will be significant.
By 2030, the carbon price could reach €45 to €55 per ton of CO₂, meaning an extra €100+ per year for an average household heated with gas.

And this is only the beginning: additional climate regulations and carbon taxes will continue to drive fossil energy prices higher.

Solar Panels: A Profitable and Sustainable Solution

Fast Return on Investment

A typical residential installation of 5 kWp costs around €6,000 to €7,000 and produces 4,500 to 5,000 kWh per year under Belgian conditions.
With an electricity price of around €0.30/kWh, this equals €1,300 to €1,500 in yearly savings.
👉 That means a payback period of just 4 to 6 years, while solar panels last 25+ years.

Protection Against Energy Market Volatility

During the 2022 energy crisis, electricity prices in Belgium soared to €0.70/kWh.
Households with solar panels were far less exposed to these spikes. On average, a system covers 60–80% of a home’s annual consumption, providing a shield against market fluctuations.

Solar Panels Boost Property Value

Homes equipped with solar panels sell for 4 to 10% more than energy-inefficient properties. With ETS2 coming, this trend will accelerate.
👉 By installing solar panels, you not only cut your bills but also increase your property’s value by €10,000 to €20,000, depending on the installation size and location.

Solar Energy and Climate: A Positive Impact

A 5 kWp installation avoids around 2 tons of CO₂ emissions per year.
If 1 million Belgian households adopted solar power, that would represent 2 million tons of CO₂ avoided annually — the equivalent of taking more than one million cars off the road.
