Choosing a solar installer in Gembloux (5030) isn’t about comparing prices at random : it means checking RESCert certification, accreditations, insurance and after-sales support. Wendows fits your panels with its own in-house technicians, from the town centre and the Abbey out to the open farms of the Hesbaye plateau — free solar assessment within 48h.
In Gembloux, solar attracts plenty of offers : door-to-door sellers passing through, subcontractors you never see again, quotes that are “too good to be true”. We install with our own in-house technicians, RESCert-certified, who know the town’s rooftops — from the centre near the Abbey and the Agronomy Faculty to the large open farms of the Namur Hesbaye.
A good installer can be spotted before you sign : RESCert certification, a verifiable company number and accreditations, public liability and ten-year structural insurance, written guarantees on both the installation and the equipment, and local after-sales support that still answers once the job is done. That’s exactly what we document in your assessment, scheduled within 48 hours and with no call-out charge in Gembloux.
The criteria that make a good installerBeyond Gembloux itself, our certified technicians work in Sombreffe, Jemeppe-sur-Sambre, La Bruyère, Chastre and Perwez, and more widely towards Namur — the same in-house team, the same guarantees across the Namur Hesbaye.

Gembloux comes under Wallonia. Beyond the subsidies, a good installer protects your investment with written guarantees and a correctly applied tax framework. Here’s what we commit to.
Public liability and the ten-year structural guarantee cover your roof and its watertightness. Always ask for the certificates : an uninsured low-cost installer shifts every risk onto you.
For a home over 10 years old, VAT drops from 21% to 6% on supply and installation. A certified installer applies it correctly on the quote, with no nasty surprise on the final bill.
Installation guarantee, production monitoring and local after-sales support reachable once the job is done. That’s the difference between an installer established in Gembloux and a salesperson nowhere to be found the following year.
The detail of the amounts, the prosumer tariff and the return on investment — so you can compare an offer on honest grounds — is on our solar panel price & profitability page. We calculate your production and your payback before any signature.

A good installer doesn’t sell a single product : they size the whole system — panels, inverter, storage — to suit your roof and your consumption. Discover each range :
High-efficiency photovoltaic modules, fitted by certified technicians. Discreet full-black aesthetics for the older buildings of central Gembloux.

See the inverters →Store your surplus to use it in the evening and boost your self-consumption — a real lever against the Walloon prosumer tariff, installed and guaranteed.
Explore the batteries →Check the RESCert certification (ask for the number and verify it), the company number and accreditations, public liability and ten-year structural insurance, and insist on written guarantees on both the installation and the equipment. Favour an established installer with its own in-house technicians and local after-sales support, rather than a passing salesperson who subcontracts and disappears once the job is done.
RESCert is the benchmark certification in Wallonia for installers of renewable energy systems, including solar. It attests to recognised training and skills. Having your panels fitted by a RESCert-certified installer in Gembloux is the best assurance of quality and reliability : we work under this certification and give you the number before you sign.
A low-cost offer is tempting on price but often hides subcontracting, no ten-year structural insurance, vague guarantees and an unreachable after-sales service. A certified installer like Wendows puts its responsibility on the line : in-house technicians, insurance certificates, written guarantees and after-sales follow-up. In Gembloux, several customers came to us after a let-down with a quote that was too good to be true.
At a minimum : professional public liability insurance, a ten-year structural guarantee covering the roof and its watertightness, the manufacturers’ product warranties (panels, inverter, battery) and an installation guarantee. Ask for the certificates in writing before you sign : a serious installer in Gembloux hands them over without being asked.
Yes. As an established installer working in Gembloux and across the Namur Hesbaye, we provide local after-sales support : production monitoring, maintenance and repairs by the same team that fitted your system. You keep a reachable contact, not a salesperson who has vanished by the following year.
Tell us your address and your project : a RESCert-certified installer calls you back, schedules the free solar assessment and gives you a clear quote, guarantees and insurance included.
