I believe baled hay or straw are good
environmental products for insulation - certainly
no toxic fumes. The fact that they need to be
thick means extra expense because of the larger
roof and the land, if its price is at a premium.

Fantastic Post Doug ,
Love seeing real world results from home , have you by chance got any charts
/ graphs of your daily / weekly / monthly figures ?

Dear 'Old' friend,
Your system has done exceptionally well. I remember your visit to our
website --www.pvmonitor.net over a year ago. A couple of questions:
1. Did you ever cleaned your array? I remember there were wild
last summer, probably resulting in a layer of smoke
a layer of dust may block up to 5% of sunlight.
2. What is the tilt angle and air-gap with the roof.? It seems to
Considering that solar panels degrade about 0.5% per year. Your system
designed, and installed very well done.
I took the liberty to look up your site record and changed the
location from Sunnyvale
to a southern Cal location, and modified some other parameters.
The stated peak power rating may some times be in error by +/- 5%.
Assuming that there will be 95% sun this noon, your system should be
3.6KW. You might check on it then, or lookup a monitoring record if
it does have
a monitoring system. Please feel free to visit our site, plus
under construction, but it gives you an 'insider' look at your PV
system; and you
could also specify a precise date & time for the benchmark. It is a
approach than the PVWatts, which takes yearly output and compared with
whole state in terms of insolation map. (Your site is performing at
norm, per the PVWatts method -- see www.pvwatts.org)
Please execuse the clunky user interface. I paid for a newly designed
can't afford a good web programmer yet.
You are doing Edison and the community a nice favor by contributing
Hope they pass a version of 'Feed-in Tariff' for California, and
Take Care, and May the Sun always warm your face and your panels!

We just finished (about 2 months ago) our first 12-month net metering
SCE and in the end for the entire year including connection fees, I
think out total
outlay for power was ~$5US (our final bill showed us using a bit more
generated so we had to pay about $5-20 IIRC).. We're using the Sharp
modules and also have a 6KW system with two Fronius inverters.. So far
I've not yet computed the payback period but I know before we had the
we were spending about $25/mo in power bills alone and were
frequently in tier 3
