One surprise by-product of the financial bail-out legislation passed this Friday appears to be a substantial increase in federal tax credits for residential solar power, upping the tax rebate from today's $2,000 cap to 30% of systems total cost in 2009.
If my reading is correct, this dramatically changes the economics of installing photo-voltaic power systems on homes, making much larger systems affordable. For example, in one specific but representative quote, a 7,000 D.C. Watt system with a gross cost of cost $57,100 that nets out to $43,447.00 after California state rebates (through the local utility, PG&E in this case) and Federal tax credits today. That same system will have a net cost of only $31,812.90 after a tax credit of $13,634.10 next year.
Basically, that solar PV system couldn't be economically justified before, but is now a worthwhile investment for a home owner.
