Out with the old… A guide to successful inverter replacement

View Webinar Video

For a number of reasons, replacing all of the inverters in an existing PV project is an increasingly common strategy among PV project owners, particularly for projects that have been in operation longer than five years. This revamping can bring advantages in terms of higher energy yields and lower operations costs, but it is also a complex process with potentially broad implications. In this pv magazine Webinar, produced in partnership with Sungrow, we’ll shine a spotlight on this revamping process, offering insight from successfully completed projects.


Out with the old… A guide to successful inverter replacement

As the number of PV systems already in operation for several years grows, demand for “revamping” by replacement off all the inverters in a project is estimated at several gigawatts per year and expected to increase rapidly through the 2020s.

There are a number of reasons why project owners are taking interest in this strategy. In some cases, older inverters may simply be underperforming, or may be struggling to get hold of replacement parts for models no longer manufactured or suppliers that have since left the market. For younger projects as well, issues with poor installation, system design or product quality also lead owners to consider inverter placement.

Revamping a project with new inverters has already been shown to pay off, and as demand begins to broaden from regions such as Italy, Germany and Spain that have a larger based of projects more than five years old, pv magazine is partnering with Sungrow to take a look into the advantages and potential pitfalls of inverter replacement.

Roberto Arana-Gonzalez, Service Sales Manager EMEA at Sungrow will offer a brief introduction to the company and Sungrow’s services in the revamping segment. And we’ll be joined by Franco Marino, Sungrow’s Regional Service Manager for Italy, who will take us further into the detail: Marino will examine the process including replacing old central inverters with string products, and other value-added services offered by Sungrow.

And this will be backed up with experience from the field with the O&M specialized service provider Stern Energy. We’ll hear from Andrea Bandini, Head of O&M for Italy, and Alfredo Beggi, Head of Sales & Development on a couple of successful projects in Italy, that are already up and running with shiny new Sungrow inverters.

I came to Germany 12 years ago for studying and working on solar technologies. Since then, I continue to be a PV enthusiast and have gathered experience working with leading inverter manufacturers, asset managers and (energy) construction companies. To ensure that all PV plants achieve its economical and environmental objectives, it is important to care for the plant life cycle. Together with Sungrow, we are now proactively promoting revamping of old plants with our newer solutions and therefore contributing to achieve “clean power for all”.
