PV repowering – More power for existing solar systems

Start inquiry

Modernisation. Efficiency. Future-proofing.

With PV repowering, we can increase the performance of existing solar systems by replacing outdated components, optimising system technology and implementing an economically attractive modernisation concept. This is ideal for operators who want to continue operating their photovoltaic systems profitably in the long term after the EEG expires or performance declines. Benefit from our practical repowering experience with our own rooftop and ground-mounted systems!

We combine expertise in project development, project management and O&M – all from a single source for maximum efficiency and minimal interface risks.

Your benefits at a glance

Increased yield on existing space - more energy yield thanks to modern high-performance modules and highly efficient inverters
Ensuring economic efficiency after the EEG expires – repowering increases the profitability of old plants in a future-oriented manner
Technical safety and reliable operation – lower risk of failure and stable performance
Planning and investment security through transparent project costing and professional monitoring
Repowering uses existing infrastructure and reduces land consumption
Review of the approval situation (urban land-use planning, etc.) and further development of the plant design
Optimisation of the grid connection situation
Integration of energy storage systems (BESS)

For whom is repowering solar installations attractive?

Investors & asset owners

to increase portfolio value and maintain the value of existing solar parks

Local communities & municipal utilities

for the modernisation of older rooftop or ground-mounted systems

Industrial and commercial enterprises

to strengthen self-sufficiency through optimised PV yields

Landowners

who wish to further enhance their site or are seeking new operators

By 2030, more than 1 GW of installed capacity from large PV plants (>1 MW) nationwide will no longer be eligible for EEG subsidies. Repowering is therefore a strategic lever for the energy transition: it significantly increases installed capacity and improves energy yields without additional land consumption.

Our process – How PV repowering works

1. Analysis & inventory assessment

Technical system check, yield measurement, regulatory approval review and profitability calculation

2. Planning & Engineering

Replacement of PV modules, inverters and substructure, as well as optimised system design

3. Integration & Operation

Monitoring, Operational Management (O&M) and Performance-Optimisation

Frequently asked questions about photovoltaic repowering

What are the advantages of repowering my solar system? PV repowering increases yield, service life and cost-effectiveness – especially for older systems after the EEG expiry.
Which components are typically replaced? PV modules, inverters, cabling, substructure and monitoring.
Is a battery energy storage system (BESS) a useful addition? In most cases, a BESS is a useful addition for further increasing economic efficiency, optimising feed-in capacity and positioning yourself correctly for the future.
What happens if the current asset owner/operator no longer wishes to continue operating the plant? Pfalzwerke AG could take on the role of future operator/asset owner for you.
