Where are Jingfeng solar PV modules made?

At present, Jingfeng has two production lines, mainly producing PERC and Topcon high efficiency PV modules, with customers more than 30 countries in Europe, Africa, Australia, South America and Asia. By the end of 2022, Jingfeng solar PV module shipments have exceeded 6.5GW.

What are the different types of PV inverters?

There are three primary tiers of PV inverters: microinverters, string inverters, and central inverters. Since microinverters are not rated for utility-scale voltages, we will largely ignore them in this article. String inverters convert DC power from “strings” of PV modules to AC and are designed to be modular and scalable.

Why did PV inverters become module-level microinverters?

Ironically enough, the drawbacks of early central inverters (mismatch losses, inflexible system design) led to the development of module-level microinverters. The PV inverter market of this era had two bookends: microinverters for residential and small commercial projects and increasingly large central inverters for everything else.

Will my project have a central inverter?

The likelihood of encountering a central inverter on a project increases with project size and age. Utility-scale projects above ~10 MW are the most common application today. Large C&I and smaller utility-scale projects from just a few years ago are likely to have central inverters as well, for reasons we’ll touch on in the next section.

Why do project owners want to buy a new inverter?

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.

How old are inverters?

The inverters in question are five to 10 years old and are beginning to fail. And not in isolated cases here and there, but with “a high degree of regularity,” according to the study.
