Existing PV plant modernisation and repowering
From condition assessment and loss analysis to targeted repairs or technology replacement, with defined boundaries, a shutdown plan and verification of the result.
Operating context
The whole application matters.
Modernisation starts by comparing documentation, operating data and the actual plant. We offer technical audits, alternative designs and implementation coordination, from replacing faulty components to renewing modules, inverters and associated systems. Assessment also considers the planned remaining operating period, potential reuse of structures and the extent of changes. Preparation connects the owner, operator, designer and relevant specialists, including coordination of documents needed to assess connection, contractual and permitting implications.
Scope of the solution
- Documentation and operating-data audit with an agreed site inspection
- Diagnostics of modules, inverters, strings, cables, structures and protection
- Alternative designs for repair, repowering and potential expansion
- Coordination of connection and permitting documents and specialist assessments
- Supply, removal, installation, commissioning, monitoring and agreed service
Engineering priorities
From operating need to design.
01Identify the causes of lost generation
Generation is evaluated against irradiation, equipment availability, outages and output limitations. String and inverter comparisons help identify areas for investigation. Depending on need, we arrange visual inspections, thermography, I–V curve measurements, insulation checks or sample electroluminescence. Methods and sampling follow the symptoms and available information.
02Match new and retained equipment
Module or inverter replacement requires electrical and mechanical compatibility checks. Design covers string configuration, voltage and current limits, DC/AC ratio, connectors, cables, mounting and protection. Retained components are checked against the new configuration. Renewal at the existing registered capacity and capacity expansion are developed as separate options with their own assessment of conditions.
03Implement the change and document the result
The plan defines removal, shutdown, installation and restart sequences. Protection settings, monitoring integration, tests and as-built records follow. Before-and-after assessment uses agreed data, measurement periods and adjustments for weather and operating restrictions. The study may also recommend a smaller repair or postponing investment.

Before we start
Questions that shape the project.
Does a new module automatically increase registered capacity?+
The resulting configuration and applicable registration and connection conditions determine the implications. Design must state module and inverter quantities and ratings, with the effects assessed before implementation.
What happens to removed modules and inverters?+
Their recording and handover are agreed in advance. Depending on condition, options can include further use, retention by the owner or collection and recycling through the appropriate partners.
