Tailor-made photovoltaic installation in Herstal (4040) and across the whole Liège Lower-Meuse, from the centre to the heights of Vottem and Liers. A local team, a free solar survey scheduled within 48h and installation in 1 to 2 days — designed for terraced worker’s roofs as well as the large surfaces of the business parks.
We install solar panels in Herstal at the heart of the Liège Lower-Meuse, with a team that knows the municipality’s building stock — from the terraced worker’s houses of the centre and Pré Madame to the large roofs of the industrial business parks, by way of the more recent estates of Vottem and Liers.
The solar survey takes place at your home, with no travel charge and scheduled within 48 hours ; we record the orientation, the slope and the shading before sizing the installation, then the same team installs the panels in 1 to 2 days.
We know Herstal rooftopsBeyond Herstal itself, we also install solar panels in Vottem, Oupeye, Saint-Nicolas and Milmort, as well as towards Liège and Visé along the Meuse — same team, same timelines across the whole Liège Lower-Meuse.
Herstal relies on the support schemes of Wallonia. Here are the levers we optimise for your photovoltaic installation, with no paperwork on your side.
In Wallonia, the prosumer tariff applies to grid use : we size the installation to maximise your self-consumption and reduce its impact on your bill.
For a home over 10 years old, VAT drops from 21 % to 6 % on the supply and installation of the panels. Applied directly to your quote.
Adding a battery and managing your consumption increases the share of solar energy you consume directly : more profitability against the prosumer tariff.
The details of amounts, the prosumer tariff and profitability are on our solar panel price & profitability page. We calculate your output and your return on investment before any signature.
A few recent installations in Herstal and its districts. Each project is handled by the same team, from survey to commissioning.
10 full-black panels on the rear pitch of an adjoining worker’s house, hybrid inverter ready for a battery. Careful layout despite the narrow roof.
Voir le chantier →16 panels on an open, due-south roof, coupled with an 8 kWh battery. High self-consumption for the household and for charging the vehicle.

« Devis clair, sans surprise, primes comprises. Un seul interlocuteur du début à la fin. Je recommande sans hésiter pour le photovoltaïque. »
From the full-black panel to the storage battery, we tailor the installation to your roof and your consumption. Discover each range :
High-yield photovoltaic modules, ideal for the open roofs of Vottem and Liers. Discreet full-black look for the terraced houses of the centre.

See the inverters →Store your surplus to consume it in the evening and increase your self-consumption — a real lever against the Walloon prosumer tariff.
Explore the batteries →We schedule the solar survey at your home within 48 hours everywhere in Herstal and the Lower-Meuse. Once the quote is signed, the installation usually takes 1 to 2 days depending on the system size, then we proceed with commissioning. Distance within Herstal or its districts does not lengthen this timeline.
As Herstal falls under Wallonia, you benefit from 6 % VAT if your home is over ten years old, and we size your installation to optimise the prosumer tariff by maximising self-consumption. Adding a battery further boosts profitability. All the figures are detailed on our price & profitability page.
Yes, most Herstal worker’s houses are suitable. During the solar survey, we record the orientation, the slope and the shading, then we optimise the layout on the best-exposed pitch — often the rear pitch, barely visible from the street, which also preserves the look of the building frontage.
It’s one of our specialities in Herstal, where the Lower-Meuse business parks offer large surfaces. We size oversized installations with micro-inverters to manage partial shading, aiming for high self-consumption and a surplus optimised against the Walloon prosumer tariff.
Yes, completely: the visit to your home in Herstal, the solar survey, the sizing and the priced quote with output estimate are free and without obligation. You pay nothing until you have approved your project.
