What is this form of subsidies by the Region?

The Brussels Region rewards the production of green energy through production subsidies, known as Green Certificates (GC, French acronym CV) . A GC is an intangible title attributed for each megawatt hour (MWh) of green energy that's produced. This title has economic value and can be sold in specialised marketplaces.

Energy savings

I'm interested, how much can I save?

An average household pays 0.21 euro cents per kWh of electricity. A HelloSun installation will produce between 3000 and 4500 kWh per year on average. Your electricity meter runs in reverse and allows you to capture this production, earning you savings of up to 941€/year. Interested?Run a simulation.


What are the criteria for solar panel installation?

It's simple. You need to own your own roof. The building must be located in Brussels. Following that, orientation, roof structure and shade are taken into account. This means that a north-facing henhouse roof down the end of a small courtyard is best forgotten.

HelloSun = Energreen + SkySun

Savings for you, cleaner air for Brussels

HelloSun was born from Léopold, Arthur – co-founders of Skysun – and Alexis’ – director of Energreen shared desire to give Brussels and its inhabitants the opportunity to convert to solar energy, panic-free.

We are delighted with our photovoltaic panels and the service provided by Energreen. Our Qualiwatt record is not yet finalized but I am confident for the rest ... Do not hesitate, it's always a pleasure to see the counter turn backward.'

Today, 3 years of production: 5430 kwh per year on average for a production estimated at the time at 4625 kwh with 16 panels. Beautiful perf, no worries. Very nice installation. I called Energreen twice for web related issues. Solutions provided immediately.
