Chinese PV manufacturer Phono Solar has developed the AC Frame-Attached Module, a module which has a microinverter attached to the frame.
Already available in the US, the new product is expected to be launched in Europe “soon”, Mariana Hall, Vice President of Phono Solar Europe revealed to PV-Tech at Ecobuild.
The new module comes with an Enphase M215 microinverter attached to the back of the frame.
According to Hall, the product has two main advantages. Firstly, partial shading no longer affects the overall power generation of the array, and instead only the shaded modules. In a traditional central inverter system, if one module is shaded it can draw down the entire system. In contrast to this, if one module is shaded using an attached microinverter, it will only affect the shaded module.
Secondly, the new module is easier to install, thus saving time, as well as offering greater flexibility. Extra modules can be easily added at a later date if necessary without having to install a new inverter.
Speaking to PV-Tech, Hall also revealed that the product, which is currently on display at Ecobuild, represents the first stage of the product development. The company is working on stage two which will see the removal of the junction box at the back of the module to create a fully integrated AC module. This is expected to be developed by the third quarter of this year and will be suitable for large-scale projects with each panel expected to have a minimum capacity of 240w.
