Gross System price to offset 12,000kWh/year in So Cal $40,392
Current State incentive $10,314
Current Federal Tax Credit $ 9,174
Total to the consumer $21,405
This will offset 100% of the bill (including night use) and could very easily return money from the electric company but I did not figure that in here.
Original average monthly bill $218/ month
30 Years at 5% Financing $116/ month
Added Tax benefit from mtg write off annually $47.52/ month
Bringing the total monthly savings to $163.52/month
Over the course of 25 years with an average annual electricity price increase of 6.5%
Your math does not work.
12000 kwh/12 =1,000 kilowatts per month
@ $218 monthly bill equals $0.218 per kilowatt. As the price of the electricity increases from the electric company, so to does the price increase for what they are buying back from your system. If the system is proving 100% of the need, there is no hedge against the increasing prices until the system becomes obsolete or the electricity used is exceeding the output of the system.
Original average monthly electric bill $218
Current system costs with incentives $21,405.
$21,405 @ 30 Years @ 5% Financing $115/ month. Here is your basic buyer calculated math. $218 dollars a month for electric bill, $115 dollars a month to buy the system. $103 dollars in savings from the electric bill. Why would I spend $115 a month to save $103? Herein lays one of your big problems with solar systems and residential buyers. If their math was better, there would not have been a subprime crisis.
So it is necessary, because of the cost of the system to sell the long term benefit of owning the system, sprinkled with a bunch of you could produce more electricity than you use, sales pitches.
You cannot consider tax benefits in mortgage write offs as this is a program currently on the chopping block to fix the economy, and counting this without consideration for increased assessment is wrong, especially when tax assessments will not go away, but tax incentives can.
At post #16 you said that solar homes sell for 17% more than non solar homes. So let’s say that 17% increase represents $1,360 annually or $113 a month on $8,000 annual taxes. (taxes are ad valorum, per the value) Here comes more buyer math:
Electric bill without solar = $218
Loan repayment for solar = $115
Increased taxes $113
Cost of having solar panels =$220 monthly
Value of installing solar = -$20 monthly
Full repayment of loan, $21,405 @ 30 Years @ 5% = $41,366.40 total repayment.
Using the $218 monthly payment ($115 P&I plus $103 not going to the electric company) it will take 127 months ( 10.583 years) to pay off the loan on the system, (Total interest paid: $ 6,179.92) just about the same time the voltage output is starting to drop before any real savings are realized. But, that 17% assessment increase in the price is going to increase in dollars throughout the life of the loan, every time the tax rates are increased.
The issue, as everyone instantly knows, is the price of the systems is still to high, relative to costs of electricity. This is by design. If, you could generate and store your own electricity for $1,000, who would need an electric company? What would those stock holders do when revenues slip as market share declines and generation declines due to decreased demand? Electric companies have millions tied up in infrastructure. We, the people, are not going to subvert it. Go off grid and no FHA loans for you guys. Electric is not like gas or oil, the sun shines everywhere. Once solar is efficient and affordable someplace, the rest of the world’s people will quickly follow. Prices are artificially high to protect the monopolies.
Solar panels generate DC electricity just like cars and RV’s. You can buy a power inverter for the car or RV to convert the electricity to AC typically for $100 or less. Buy one that’s rated for solar DC conversion and the price quadruples and more. Throw in some technical electronic terms like pure sine wave and a couple of extra resistors and wham, instant barrier to entry.
But in all this discussion, your posts do not appear to be from the guy who screws panels together on roofs. Just saying.
