P.C. Costs/ another view
With all of this talk about true costs, here's a business example of a large
p.v. systems cost in California. . .gleened from the p.v. industry marketing.
~ * ~
The U.S.A. Federal Government has a permanent 10% Business Energy Tax Credit
for Renewable Energy Equipment, which includes solar electric, solar thermal,
and wind power systems.
In addition, this Federal Business tax Credit also includes an Accelerated
5-year Depreciation Schedule which allows 100% of the system cost to be
subtracted from your taxable income over the first 5 years.
(Applies to commercial only, which can include a home business)
~ * ~
For example: a 5 kilowatt (AC) p.v. system for someone in a 34% fed. tax
bracket.
system cost approx. $35,660. install $6,000. Total
$41,660.
* p.v. system cost $41,660.
* 10% 1st. year Credit <$4,166>
* 20% 1st year depreciation
(1/5 of $37,494 = $7498 x 34% tax bracket) = <$2,549>
* 20% Depreciation/year (year 2-5)
($2549 x 4 years) = <$10,198>
* State of California rebate
(aplies to both commercial and residential) <$14,649>
---------------
* Installed cost after rebates (after 5 years) $10,098
Value of electricity generated:
(assuming an average cost of $ .20 per KWH over the next 5 years
* 5 KW p.v. x 5 ESH/day x 365 = 9,125 KWH/year
* 5 years x 9,125 KWH/year = 45,625 KWH/5 years
* 45,625 KWH x $ .20/KWH = $9,125 additional savings over 5 years
($1,825/ yr.)
Value of power generated (over 5 years) <$9,125>
Net cost after year 5 <$973>
Positive cash flow after year 6 + $852
payback = $10,098 : $1,825 = 5.53 years
Most solar panels today have a 25 year warranty
~ * ~
Now, I know that not everyone on this list has these rebates, but many do.
And, there is an economy of scale for some sytems.
But, there are some great micro-sine inverters out there that basically allow
you to
slap one (a little bigger in size than a palm pilot ) on the back of a panel;
add a cord and plug; and plug it into an exterior G.F.I. receptacle.
The power co's may not approve. . .but it's U.L. approved. And works!
There will definately be a point in the future where the rising costs of
power (elec.) will cross the lowering costs of p.v. panels; so that the
payback will be even shorter.
But, this is looking at a purely economical point of view.
What about all of the bragging rights you'd have at parties,
and the good Karma points you'd rack up.
So Flame ON. . I won't care because I'll be away for 5 days :)
