New testing conducted at France's oldest PV system have shown that its solar modules can still provide performance values in line with what the manufacturers promised.
For Enphase, the data is available via a HTTP API. The combiner box (their hardware that all the inverters connect to) connects to your network via wifi or Ethernet, and you can hit its IP directly.
Unfortunately it’s kinda-cloud-dependent these days. The API used to take a basic username and password, nice and simple. Now, you need to hit a cloud API to get an access token (and periodically refresh it). The API is entirely local once you have the access token though, and there’s no problem with polling the data once per second.
