Having welding, machining, and ceramic equipment, our power bill was
getting out of hand. ( than $200/mo) We recently installed 30- 230w
solar panels and now have watched our power meter go backwards at
rates up to 6sec/rev. In just a few days our panels generated more
than 200kwh and one of those days had cloud cover. Oh and we used
the solar installation to also create a car port. It may take a few
years to recover the cost, but just watching that meter go backwards
was worth quite a bit.

in may i put in a 7.5kw solar installation, just in time for the main
summer a/c season. last month's bill was $40, whereas same month last year
was $200.

the rebates covered 80%, payback is estimated at 4.5 years. panels are
guaranteed for 25 years. converter is guaranteed for 10 years.

you'll want to rinse them off occasionally. i do so about ever 3-4 weeks,
as the dust builds up. cleaning will get me a 3-5% gain.

Charlie:
Thanks for the info. We'll be watching closely the panel production and
checking for dust. Usually, we get an evening wind that will probably keep
it pretty clean. At least the wind brings most of the loose dust around and
in my garage door.
