We update the database based on manufacturers' requests and release it with each new version of PVsyst.
It's not feasible for us to track all new products from every manufacturer worldwide, and we avoid including data without the manufacturer's acknowledgment.
However, you can easily create your own components. The simplest method is to select a similar device from the database, adjust its parameters according to the manufacturer's datasheets, and save it under a new name, creating a new file in your database.
A tutorial on this process is available on YouTube: https://www.youtube.com/c/PVsystTutos, under the Component Database page.
