Lol PG&E is getting such a good ROI on their investment. Why doesn't PG&E say this is unfair? Since they're all about equity and fairness.
All they have to do is bribe Newsom for $900k, then get him to appoint a head of the CPUC that will help crush the residential solar industry in California! $900k to get billions extra into PG&E's perpetual bottom line.
And PG&E complains your solar array ROI is too high. Hypocrites.
I would argue that using the ROI calculation is as ridiculous for PG&E as it is for rooftop solar, even worse.
"ROI" is, l believe, most accurate and useful when comparing two different investments. Such as, should I put my money in the stock market or buy an apartment building, or buy government bonds?
What is PG&E supposed to do with their money other than spend it on infrastructure? They ought to have a
friggen Zero "ROI" ........ oh, sorry me, I already missed the boat where somehow they are allowed to be investor owned utitlities. Nice dumb move.
Used in the same way as any other investment, i.e., if I spend $50K on solar system or $50K on a bond, the solar investment is great. For my approximately $50k I get electricity worth about $6,000 per year, which is a nice >10% return.
Of course, in solar salesman world, its not how much the system produces, its whether it produces it at a cheaper cost than you would otherwise buy it at, which is nothing like any "ROI" calculation I have ever seen.
It does produce energy at a cheaper costs than buying it, duh. The kick in the nuts is
that the only reason for that is that you avoid the cost of the grid, which is most of the cost of electricity.
