Repowering for significant revenue growth:

Faster Return-on-Investment and higher income secured in the long-term

Investments in the operation of PV plants are investments in the dynamically growing market for renewable energies and thus a decision designed to ensure sustained business success. A requirement for this is that all performance parameters for yield formation remain stable. To this end, ADLER Solar provides you with an attractive fulfilment service for maintaining the functionality of your PV plants.

In much the same way that every biological organism ages and every mechanical construction wears out, PV plants lose out in efficiency over time depending on their size and technical condition – either by modules degrading or a drop in components’ performance.

ADLER Solar carried out a performance analysis on our behalf to determine the delta between the ACTUAL and original output current for our PV plant. As a customer, we benefited primarily from the long-standing expertise of ADLER Solar as a full service provider, and, secondly, the entire process was managed efficiently from one single source. The skilled and timely execution of the repowering project resulted in a significant optimisation of performance and thus an increase in our ROI.
