Yea. Depending some, but not a terrible amount on location, and using PVWatts numbers for Miramar MCAS, for a mostly south facing, unshaded array tilted at ~ 20 deg. or so, using the old (current) DR - SES rates and times, every installed STC kW of PV will produce about, something like $ 510 /yr. in revenue value (at an average value/generated kWh of ~ $0.2998/kWh) to offset an electric bill. The same array, working under what looks like the new DR - SES rates and times will probably, if the numbers currently being thrown about hold, produce something like, roughly,$390 - $400 /yr. in revenue value (at an average value/generated kWh of ~ $0.2296/kWh) to offset an electric bill. The lower average value is a direct result of peak pricing time shifts that cause the strong solar generating times to carry a lower per kW value both when used and when generated.
So, provided that the array offsets less than 100 % of usage, a 5 STC kW array will produce, very roughly, and subject to how the final DR - SES rates and times flush out, ($510 - $395)* 5 = ~ $575/yr. less array revenue to offset an electric bill, regardless of the size of that bill. Oversizing an array will change those numbers and actually reduce the $ offset value per kWh produced, mostly because of the low amount the POCO pays for overgeneration.
