I have a rooftop installation from 2007. Specs are at the bottom. I would like to get more power from the system but cannot increase the footprint. I was considering replacing panels in one or both strings. In addition, I would get a new inverter. This will allow me to keep the rack and avoid the added costs of a complete tear down and installation of new system. I was considering replacing individual panels or an entire string with panels in the 400w range.
Any suggestions or pointers to previous posts that address this? What works, what to avoid, etc? Thanks
