I followed the suggestion in post #3 here (https://www.solarpaneltalk.com/forum...tou-vs-non-tou) and built out a spread sheet for my last year of SDG&E electric use (thanks JPM!).
Using PVWatt I had to eyeball my azimuth and roof pitch. Are there tools online to help me get these figures more accurate?
Once Excel spit out the results I had to go back and double check my work. I'm on Schedule DR which is basic two tier use. I've checked the SDG&E calculator and it has always said the TOU was the same or some were about 5% less. However with my 12 month actual usage plugged into the DR-SES rate, a rate which is only available to Solar households my bill shows 1/3 lower than I paid under Schedule DR. Can this be right? I with the PVWatt solar generation numbers I backed into a system size that is close to what several installers recommended to get 90-100% offset so it seems like this should be right. But it doesn't make sense to me that the DR-SES rate plan would be so much cheaper.
So sanity check request-does my result fit with what other San Diego folks have calculated in the past?
