6 Key Influences that Determine PV Performance Ratios

Building a solar energy plant is a big challenge and there are important aspects that you need to take into account. From engineering to becoming operational is a long way, with many stakeholders that require attention. One thing that is esential is monitoring the performance ratio (PR). But where to start and how to measure the effectiveness of your solar project?

The difficulties of performance ratios

The performance ratio is a comparison of the final (actual) yield to the reference (design) yield, but that is not where the difficulty lies. Performance ratios for any individual solar energy project come in a variety of forms, theoretical and actual, related to different phases of the project; design, installation, commissioning, contractual agreements and operational. In addition, there are many factors that influence the calculated outcome, from the components selected to the environmental conditions.

We have published a whitepaper that sums up the 6 key influences on PR and how to deal with them. We hope that this will help you choose the performance ratio that fits your needs.
