Bespoke photovoltaic installation in Liège (4000) and across the whole conurbation, from Outremeuse to the Cointe hillsides. A Liège team, a free sunlight survey scheduled within 48h and installation in 1 to 2 days — prosumer tariff and self-consumption optimised for your Meuse-valley roof.
We install solar panels in Liège and across the whole Meuse conurbation, with a team that knows the city’s rooftops — from the grand townhouses of Outremeuse to the well-exposed villas on the Cointe and Sart-Tilman hillsides.
The sunlight survey takes place at your home, with no call-out fee and scheduled within 48 hours ; we calculate your expected output, size the installation and fit it in 1 to 2 days, from securing the panels to connecting the inverter.
We know Liège rooftopsBeyond Liège itself, we also install solar panels in Seraing, Herstal, Sclessin and Angleur, as well as towards Seraing, Herstal and Visé along the Meuse — same team, same lead times throughout the province.
Liège falls under the schemes of Wallonia. Here are the levers we factor into your survey to optimise the profitability of your installation.
In Wallonia, grid injection is governed by the prosumer tariff and the dual-flow meter. We size your installation to account for this and maximise whatever is most advantageous for you.
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.
With the prosumer tariff, it is the energy consumed on site that pays off the most. We size the installation — and a battery if needed — to increase your share of self-consumption.
The full breakdown of tariffs, conditions and profitability calculations is on our solar panel price & profitability page. We put together the entire file : you pay nothing upfront and fill in no forms.
A few recent installations in Liège and its districts. Every project is handled by the same team, from the sunlight survey to commissioning.
A well-exposed hillside roof, 20 panels facing due south and a central inverter. An installation geared towards self-consumption with a battery as a complement.
Voir le chantier →A steep pitch on the courtyard side, 11 panels laid out to work around a chimney and a party wall. Micro-inverters to manage the district’s partial shading.
Voir le chantier →9 panels on a narrow roof, dual-flow meter connection and sizing matched to the household’s daytime consumption. Prosumer tariff optimised.

« Devis clair, sans surprise, primes comprises. Un seul interlocuteur du début à la fin. Je recommande sans hésiter pour le photovoltaïque. »
From the photovoltaic panel to the inverter and the battery, we tailor the installation to your roof, your consumption and your budget. Explore each building block :
The heart of the installation: high-efficiency photovoltaic modules, suited to steep pitches as well as the large open roofs of the Liège hillsides.
Discover the panels →Central inverter or micro-inverters for the shaded roofs of Outremeuse and the centre: we choose the solution that maximises your real output.
See the inverters →To store the surplus and increase your self-consumption against the Walloon prosumer tariff. Ideal on the high-output hillside villas.
Explore the batteries →In Liège, a well-oriented installation produces in the region of 900 to 1,000 kWh per kWp installed each year, depending on the orientation, the pitch of your roof and shading. During the free survey, we measure the actual sunlight on your roof and give you a costed output estimate specific to your address.
As Liège falls under Wallonia, your installation is subject to the prosumer tariff and the dual-flow meter. In practice, the energy consumed directly on site is the most advantageous: we size the installation — and a battery if needed — to maximise your self-consumption and limit the impact of the prosumer tariff.
No, that is our daily work on Liège rooftops. The steep pitches of the Meuse-valley grand townhouses are very well suited to photovoltaics, and we adapt the mounts and layout to the varied orientations of the hillsides. In the event of partial shading, micro-inverters allow each panel to be optimised.
Not always. With the Walloon prosumer tariff, a battery becomes worthwhile when your output regularly exceeds your daytime consumption, which is common on the large hillside roofs. During the survey, we cost both scenarios — with and without a battery — so you can decide with full knowledge.
Yes, completely: the visit to your home in Liège, the sunlight survey, the sizing and the costed quote are free and with no obligation. You pay nothing until you have approved your project.
