I just thought I would chime in here again. As I stated in my last
post im a cabinet maker by trade and I also do 5 or 6 PV solar systems
a year, none of witch do I give an hourly rate. When I bid a cabinet
job I start off with a base square foot price of $000.00 and then go
up from there depending on the complexity of the job. When I bid a PV
solar installation I use a base price of $.50 per watt ( all the
other installers are getting $.00 to $.50 ) There are ways if the
home owner will work with me that I have gone to $.50 per watt. The
9856 watt system I just did, my install price was $2,000.00 and it
took me about 40 hours ( just me working ) I make good money and I do
a good job. I dont make any money on the system, I set up the system
with the distributor and have the homeowner pay direct and make my
money on the install end. I was $5.000.00 installed and the other
solar Co. was $0,000.00. Now there is only 3 top distributors out
here that are competitive in price. What im saying is that chances are
that I got my equipment from the same place as the other guy and there
was a $5,000.00 difference in our bottom line prices. Mind you im not
saying that the other guy shouldnt markup his equipment after all
hes in business to make money. I just dont have to make that much.
If you are so sure you can put 150 holes in your roof without a leek
and that its so easy to hookup $0,000.00 or $0,000.00 worth
equipment without a problem then  Giver a go }:o)

Peace along the way

What is your location ? You need an 'insolation map'. Bet the salesman didn't
tell you that ! This can make > 200% difference in the cost/payback.

Examples for Europe here.

Similar stuff does exist for the USA but seems to be less well organised.

Also beware of seasonal changes in insolation. In Northern climes it's
worthless, especially in winter when you need it most

Another popular con-trick. Their payback is feeble compared to other energy
efficiency measures.

Now wonder why the salesmen want to sell you the most expensive, worst
performing, lowest payback options.

Got it yet ?

Maybe in the UK, but here in northern NY where the winter temperatures drop
below 0 F (-18C) they are quite a savings.  Of course how much they save you
depends in part on how much glass area you have.
