Six important changes for your solar grants in 2026
2026 is no revolution, but several adjustments have a direct impact on the amount of your grants and the steps to follow. Here’s what you need to know before launching your project.
- Higher green-certificate rates in Wallonia
The CWaPE has revised the buy-back price of green certificates upwards for 2026, from around 85 € to 92 € per certificate. For a 6 kWc installation, that represents roughly 300 to 400 € extra over the full duration of the scheme.
See Wallonia grants in detail → - Renolution v2 in Brussels: raised caps
In Brussels, the 2026 Renolution reform raises the grant cap for low-income households: up to 6 000 € (vs 5 000 € in 2025) for the photovoltaic installation. The application procedure has been fully digitalised since January 2026.
Renolution photovoltaic details → - Digital meter rolled out across Flanders
Since 2023, the digital meter ("digitale meter") has been the standard in Flanders. In 2026, Fluvius has completed the roll-out: every new solar installation must be connected to a digital meter. This changes how the prosumer tariff is calculated.
Understand the prosumer tariff → - New Fluvius prosumer rate for 2026
Fluvius has introduced a new way of calculating the prosumer tariff, based on the installed capacity in kWc rather than on net consumption. For installations of 3 to 6 kWc, the impact can be positive or negative depending on your self-consumption profile. Our simulator factors in this new calculation.
Simulate the 2026 prosumer tariff → - Wider eligibility conditions (all regions)
In 2026, several regions have relaxed their eligibility conditions: Wallonia now accepts flat-roof installations without any orientation requirement; Brussels drops the prior energy assessment requirement for Renolution photovoltaic files under 6 kWc.
- Digitalisation of administrative procedures
In 2026, all grant procedures are available online: the Renolution portal in Brussels, the CWaPE form in Wallonia (overhauled in March 2026) and the Fluvius customer area. We handle all of these procedures for you.
The 2026 solar grants: updated conditions and amounts
Here is the detail of the 2026 mechanisms region by region, with the updated eligibility conditions. We check your entitlements and calculate the exact amount for your situation.
CWaPE green certificates 2026: rate revised upwards
The 2026 CWaPE rate revision increases the buy-back price of green certificates. The mechanism stays the same: green certificates are awarded in proportion to production and bought back over 5 years. What’s new: the online declaration form was fully overhauled in March 2026 to simplify filing the application.
- 2026 rate: ≋ 92 € per green certificate (vs 85 € in 2025)
- Declaration via the revamped CWaPE portal (March 2026)
- Flat roofs accepted without orientation requirement in 2026
- Qualiwatt-accredited installer or equivalent required
Renolution v2 2026: raised caps + 100% digital procedure
Brussels is strengthening its support in 2026 with Renolution v2: the caps are raised for all income levels, and applications are filed exclusively online since January 2026. Brugel green certificates remain unchanged (3 €/panel/year, 10 years). The two mechanisms can still be combined.
- Renolution v2 grant: cap 6 000 € (low income), 4 000 € (middle income)
- Mandatory digital filing via Brussels Environment: before works begin
- Home older than 10 years: condition retained
- Prior energy assessment requirement dropped for installations < 6 kWc
- Brugel green certificates: declaration within 12 months of commissioning
Digital meter rolled out + new Fluvius prosumer rate 2026
In 2026, the digital meter roll-out is complete in Flanders. Fluvius applies a new prosumer rate based on installed capacity, which changes the profitability of small and medium installations. The Mijn VerbouwPremie grant is widening its income eligibility criteria in 2026.
- New Fluvius prosumer rate 2026: based on installed capacity (kWc)
- Digital meter mandatory for every new installation
- Mijn VerbouwPremie: income criteria relaxed in 2026
- Fluvius registration: lead time cut to 30 days (vs 60 days before 2026)

Indicative 2026 estimate, excluding 6 % VAT and Flemish municipal grants. Wallonia: 92 €/CV rate, 5 years. Brussels: Brugel 10 years + Renolution by income. Flanders: prosumer + Mijn VerbouwPremie.
6 kWc installation in Wallonia: impact of the new 2026 rate
A concrete case to illustrate the difference with 2025. The higher CWaPE rate improves the net return on investment for the same installation.
Indicative 2026 example, excluding battery storage. Gain vs 2025: the new CWaPE rate improves the total grant by around 500 € over 5 years. Green certificates are received annually. Request your quote with the 2026 rates built in.

Your questions on the changes to solar grants in 2026
What really changes for solar panel grants in 2026?
In Wallonia, the CWaPE rate rises from around 85 € to 92 € per green certificate, a gain of roughly 400 to 500 € over 5 years for a 6 kWc installation. In Brussels, Renolution v2 raises the grant caps (up to 6 000 € for low incomes) and imposes a 100% digital procedure. In Flanders, the digital meter is now mandatory and a new prosumer rate based on installed capacity is in force.
Is the green-certificate rate in Wallonia guaranteed for the full 5 years?
The rate is set on the date of declaration with the CWaPE and guaranteed for the 5 years of the scheme. If you declare your installation in 2026 at a rate of 92 €/CV, that rate applies until 2031. It will not be affected by any future CWaPE revisions.
How do you file a Renolution application in Brussels in 2026?
Since January 2026, the procedure is fully digital via the Brussels Environment platform. The file must be submitted before works begin. You’ll need to provide: a detailed quote, identification of the home (older than 10 years), and the certified installer’s details. We handle this entire procedure for you.
What is the prosumer tariff and how does it change in 2026 in Flanders?
The prosumer tariff is a levy charged by Fluvius on solar panel owners in Flanders who inject electricity into the grid. In 2026, Fluvius changes the calculation method: it is now based on installed capacity (kWc) rather than net consumption. For small installations with good self-consumption, the impact is limited.
Does the 6 % VAT change in 2026?
No, the reduced 6 % VAT for renovation works on a home older than 10 years is maintained in 2026 in all three regions. The conditions stay the same: home used for private purposes, more than 10 years old, installation carried out by a professional. On an 8 000 € installation, the saving is around 1 200 €.
Can you still claim 2026 grants if the installation was carried out in late 2025?
Yes, under conditions. In Wallonia, the applicable rate is the one in force on the date of CWaPE declaration (not the installation date). If you declare in 2026, the 2026 rate applies. In Brussels, the Renolution grant is tied to the filing date of the file: a file submitted in 2026 benefits from the Renolution v2 caps. We check your situation and optimise the timing.
