System renovation

An ageing installation does not always need to be replaced entirely.

Panels, inverter, cabling or monitoring: a diagnostic assessment identifies precisely what should be retained, repaired or replaced.

The benefits

What choosing renovation delivers for you.

Restore a reliable installation

Rectify faults and bring your system back up to standard without replacing everything.

Keep what still works

Repair or replace only the components that genuinely require it.

Extend your system’s lifespan

Upgrade components that have become limiting factors to keep generating solar energy in optimal conditions.

The diagnostic assessment

Understand before taking action.

01

Generation

Compare measured generation against initial expectations to identify any drop in performance.

02

Modules

Inspect the visual condition of the panels and identify any defects or damage.

03

Inverter

Check its operation, any error messages, and its compatibility with the system.

04

Cabling & protection devices

Inspect electrical connections, protective devices, and their compliance.

05

Structure

Assess the condition of the mounting system and, if necessary, the roof.

06

Monitoring

Ensure generation tracking is fully functional and usable.

Our approach to intervention

A tailored response to every need.

A renovation does not mean replacing your entire solar installation. It is based on the actual condition of each individual component of your system.

Preserving existing equipment

Keeping what still works.

The diagnostic assessment identifies components that remain in good condition and compatible, avoiding unnecessary replacements.

Modules that still perform well
An older installation does not necessarily need replacing. If the modules are functioning properly, they can continue generating power while work focuses elsewhere.

Infrastructure that remains fit for purpose
Mountings, conduits, or other existing components can often be retained when in good condition and compatible with the chosen configuration.

Components involved

What can be adjusted, depending on your installation.

Photovoltaic modules

Specific replacement of panels that are damaged or no longer compatible with the rest of the installation.

Inverter

Repair or replacement based on condition, compatibility, and current standards.

Cabling & protection devices

Inspection and upgrade of electrical connections and protective devices where necessary.

Monitoring

Restoration or modernisation of generation tracking.

Mounting system

Inspection and intervention only when its condition requires it.

Batteries

Adding or replacing a battery to store surplus generation and use it whenever you need it.

Repowering

Your installation can do even more.

Heat pump, electric vehicle, battery, or underutilised roof space: as your needs evolve, a simple renovation is sometimes not enough. Repowering allows you to adapt your installation to your new energy demands.

Roofing works

When the roof also requires renovation.

Roofing work may require the temporary or partial removal of your installation.

Younergy then manages the entire scope: storing equipment, inspecting dismantled components, coordinating with the roofing contractor, adapting the mounting system if necessary, then reinstalling and recommissioning the system.

We coordinate the photovoltaic portion of the project in close collaboration with the other trades on site.

Our process

From assessment to recommissioning.

We inspect the actual condition of your installation and identify the root causes of the issue encountered.

We distinguish what can be retained, repaired, replaced, or upgraded, and present you with suitable options.

We carry out only the agreed works, coordinating any necessary adjustments.

We verify the proper operation of the installation and restore reliable generation monitoring.

Like them, regain a dependable installation.

Let us assess your installation.

Year of installation, recent generation figures, observed symptoms, inverter status, existing monitoring, potential roofing works: just a few details are enough to prepare a constructive initial consultation.

Our projects

Solar energy seamlessly integrated into architecture.

Second life & recycling

What happens to dismantled components?

A module that is still functional does not automatically need to be recycled.

A second life is sometimes possible—an option we evaluate with you depending on the dismantled components. Damaged or end-of-life components are directed to dedicated Swiss recycling schemes.

FAQ

A persistent drop in generation, an inverter error, monitoring that no longer functions, or visibly damaged components are all clear indicators. A diagnostic assessment will confirm this precisely.

No. Most breakdowns involve a specific component, most often the inverter. The diagnostic assessment determines what genuinely needs to be replaced.

Yes, provided they are electrically compatible with the remaining modules. This is a point we systematically verify prior to any intervention.

In many cases, yes, if they are in sound condition and comply with current standards. We inspect them thoroughly before deciding whether they should be retained, overhauled, or replaced.

We select a model that is fully compatible with your existing panels. Depending on the scenario, this replacement can also enhance generation tracking or allow for the addition of a battery.

Yes. We carry out a diagnostic assessment of the existing installation, regardless of the original installer, before proposing any intervention.
