I'm looking into getting a Tesla solar system. I've done quite a bit of looking but haven't been able to nail down a few questions.
If I get a 7.2 kW system (no PW) and have net metering:
1. If my house is demanding more power than the solar system can provide at any given time (say 11 kW cause I'm charging my M3LR) does the solar sytem put 7.2 kW (or max pull from my system....whatever it's generating) while pulling the excess (~ 3.8 kW) from the local power company? i.e. can it combine the power? Or, does it decide that it can't handle the load and pull all power from the power company and "waste" the power generated from my solor until my demand goes down?
2. If I decide I want/need more capacity in a year or two; can I just buy/add/upgrade another 2.4 kW of panels (and maybe get another inverter) and increase my system to a 9.6 kW? Would that be way more expensive than just getting a 9.6 kW system to start with?
Thanks so much for any help!
