If one has excess power at true up time, since PGE only writes like 3 cents per KWH, no one ever would oversize to get money back!!!!Thanks all!
I'd love powerwalls to complete the system but I can't justify the $ for it because the payback isn't there (just based off of the Tesla's website of savings over 20 years). But, it seems with NEM 3.0 the math would all change and power walls would increasingly be favored.
My energy bill will not reflect my actual usage since I am not charging my car at home, will I receive any pushback if I want to an oversized system relative to my existing energy needs? I heard that PG&E will push back hard on allowing customers to get an oversized system as they don't want to be in the business of writing surplus checks.
Also, given TOU I heard that it may be advantageous to have the panels be west facing rather than south facing. South facing will generate the most kW but west facing will generate more power during the peak hours. Will Tesla walk through all the scenarios and create the best layout to optimize against the existing TOU plans? Or, will they simply put as many panels as possible south facing because that direction generates the most kW (without regards to west facing generating more energy during peak times)?
Even though I thought I had put on too large a system, things change. Now I find it is too small with my PW's. Luckily, I have put on 2 11.4K inverters so my wiring and stuff is all ready for as many panels as I can fit, which will not be enough to peg the inverters, but what the heck.
