OK, I just got my year "true up" from S.D.G.&E for this past year. I was really curious about what the situation would be. Like John, part of my motivation was to get away from "paying those crooks at S.D.G.&E." My system went on line June 15th of last year, so I'm missing about half a sunny month of generation because the "true up" ended the end of the month before the system went on line. Here are some numbers. My system cost $27K. With the tax credit I got $8.1K back from the Feds, so net cost was $18.9K. My average monthly electric bill was something like $250/mo. (IIRC) or very close to $3K/yr. My "true up" statement gave me a credit of $41.57 after S.D.G.&E.'s fees were deducted. (The company said they tried to match generation and usage.) So if this past year is any indication, the system should pay for itself in about 6.3 years. The company said approximately 5 years for pay off. I have 25 panels that can generate a max of 300-315 W/hr./panel so max is 7.5 KW/hr. Unlike John's, my system doesn't generate the same if it's not sunny or it's raining, so during winter months, generation is down. My system generated a net of 255+ KWh in Nov. '16. This past April and May the system generated 1.4MWh+ each month. On balance, it looks like this thing is going to work out OK if there is no damage/disruption to the system. Congrats again, John. I'm hoping we & lots of others who got in on the net metering program will be able to stick it to S.D.G.&E. on a long term basis.
