From a financial standpoint - will you spend $2,000 on your energy
bills in 10 years? If not, how many years do you estimate?
However, reducing your carbon footprint has value to all of us...

No. Don't be stupid, we'll build some of these.

Maybe they meant 9059 kWk p.a. ?

Based on NREL for Sacramento, CA, not too far from Chico, 9059kWh per year
would be 6500 DC Watt peak, not an unreasonable system for $2,000 before
Plugging 6500 Watts DC and Chico CA in to the Kyocera calculator yields
System Cost $2,000
CSI PG&E EPBB (Residential) (Step 4), 100% DF $0,559
Federal Tax Credit (Res.) (Jan. 2009) $2,432
less Total Incentives $2,991
NET COST $9,009
First year electric bill savings: $6 per month
$400 annual electric bill before PV.
