Shaded roof
Chimney, tree, neighbouring building: with a central inverter, a single shaded panel penalises the whole chain. The micro-inverter isolates the problem panel by panel.
The micro-inverter replaces the central inverter with a small device under each panel: each module produces independently. If one is shaded, the others keep running at full capacity. wendows installs this equipment, activates it and stays your single point of contact for warranty and after-sales service.
The micro-inverter is not always necessary, but on some roofs it changes everything. Here are the situations where we recommend it most often in Belgium, to be confirmed during the survey.
Chimney, tree, neighbouring building: with a central inverter, a single shaded panel penalises the whole chain. The micro-inverter isolates the problem panel by panel.
Several pitches, orientations or different inclinations: each micro-inverter optimises its panel independently, where a central inverter would level down to the bottom.
The current is converted right at the panel: no high-voltage direct current (DC) on the roof. A reassuring approach on fire safety and intervention.
The app shows production panel by panel, not just the total. A failing or soiled module is spotted immediately, which makes after-sales service very precise.
Beyond the principle, it is the decentralised architecture that changes everything: per-panel production, safety and fine-grained tracking. The benchmarks to know, set out by our teams.
A micro-inverter under each panel replaces the central inverter. Each module produces independently: a shaded panel does not penalise the others, unlike a string architecture.
Each micro-inverter is sized for the power of one panel. You add as many as there are modules: the installation stays coherent even when enlarging the roof later.
Efficiency is not just about the conversion rate: by recovering production module by module, the architecture sharply limits losses on shaded or complex roofs.
Micro-inverters often benefit from a long manufacturer's warranty, which can go up to 25 years depending on the range. wendows handles the liaison and the intervention.
The tracking shows production panel by panel. A failing module is spotted immediately, which makes remote diagnostics and after-sales service particularly precise.
The decentralised architecture can evolve towards storage depending on the ecosystem chosen. If the battery is part of the project, we frame the compatibility during the survey.

Fitting a micro-inverter under each panel requires method and careful commissioning. Our teams install the micro-inverters according to the manufacturer's rules, activate the app and handle warranty and after-sales service directly.
The micro-inverter is not always the best option: it all depends on your roof. Compare the architectures and the brands, then we decide together during the survey.
An overview of inverters: string, micro-inverter and hybrid, their role and their logic, to place the micro-inverter in the full picture.
All about the inverter → vs microIf storage is at the heart of the project, the hybrid manages panels and battery in a single device — a different logic from the micro-inverter.
All about the hybrid → vs microThe SUN2000 hybrid driven by FusionSolar: a residential benchmark when you want the inverter, the battery and the monitoring in an integrated pairing.

See solar panels → vs stringAt the opposite end from the micro-inverter, the robust, proven German string inverter for clear roofs. A safe bet on the central component side.
See SMA equipment →With a central (string) inverter, all the panels are wired in series: if one is shaded or soiled, it drags the whole chain down. The micro-inverter solves this problem by placing a small inverter under each panel. Each module produces independently, and a weak panel no longer penalises the others.
It is the go-to option for complex roofs: several pitches, different orientations, shading from a chimney or tree. Where a central inverter would level production down to the bottom, the micro-inverter recovers the yield panel by panel. On a clear, south-facing roof, however, a string inverter is often enough.
"On a shaded roof, the micro-inverter does not cost more: it is the lost yield, panel by panel, that would cost you.
The micro-inverter also brings a safety advantage: the current is converted right at the panel, with no high-voltage direct current (DC) on the roof. And on tracking, the app shows production module by module — a failing panel is spotted immediately. This is where our role as installer matters: rigorous installation, commissioning and precise after-sales service.
One inverter per panel. Each module produces and supervises itself independently: the shading of one panel no longer penalises the others, and tracking happens at module level.
On the budget side, the micro-inverter is priced per panel rather than as a single central device. The difference is justified by anti-shading, safety, fine-grained tracking and an often long warranty. To get a sense of your project, start from our price page, then request a detailed quote.
The micro-inverter is priced per panel, not as a single device — that is the logic of the decentralised architecture. Here are starting ranges for equipment installed by our teams, subsidies and reduced VAT applied afterwards.

It is a small inverter placed under each panel, which converts the current from that single module. Instead of one central inverter for the whole installation, you have one per panel. Each module produces independently of the others.
Mainly to handle shading and complex roofs: a shaded panel no longer penalises the others. It also brings better safety (no high-voltage DC on the roof) and panel-by-panel tracking. On a clear, south-facing roof, a string inverter is often still sufficient.
Yes, that is precisely its strong point. Chimney, tree or neighbouring building: each micro-inverter isolates the panel concerned, so that the modules in the sun keep running at full capacity. It is the most relevant architecture on partially shaded roofs.
Yes. The monitoring app shows production module by module, not just the total for the installation. A failing or soiled panel is spotted immediately, which makes remote diagnostics and after-sales service very precise.
Depending on the range, the manufacturer's warranty can go up to 25 years, longer than that of a classic string inverter. wendows handles the liaison and the intervention. The exact conditions are stated on your quote.
Expect from around €110 per panel, plus the control gateway. The total cost depends on the number of modules: that is the logic of per-panel pricing. Subsidies and 6% VAT deducted afterwards.
