Exactly, the topic with regards to photovoltaic systems - "3.1
Working Safely with Photovoltaic (PV) Systems" The technical
derivations are typically straight forward, it's the non-technical
derivations which would be typically the issue. Simply would suggest
the following:
NFPA 10: Standard for Portable Fire Extinguishers
http://www.nfpa.org/aboutthecodes/AboutTheCodes.asp?DocNum=10
NFPA 70E: Standard for Electrical Safety in the Workplace® --- NFPA
70E one reads other applicable OSHA is listed.
http://www.nfpa.org/aboutthecodes/AboutTheCodes.asp?DocNum=70E
Online OSHA Outreach & Safety Training Institute
http://www.360training.com/osha-outreach-training.cfm
http://www.industrialinstitute.com/OSHA/general-industry.cfm
As indicated previous, suggest both:
BlueVolt Continuing Education
http://go.bluevolt.com/CoBrandTemplate/CourseCatalog.aspx?Brand=default&CategoryID=884
Specifically, for instance, "Industrial Safety"
"Course Description: This course is designed to give site workers some
knowledge of industrial safety concepts. The primary topics include
fall protection, ladders, stairs, aerial lifts, scaffolding, and
confined spaces. OSHA regulates these structures to help ensure their
safety and integrity."
EC&M eTradeshow
Suggest teleporting to the "Archive Library"
"Picking the Proper PPE " : Occupational Safety and Health Act (OSHA)
Electrical Safety Regulations; 29 Code of Federal Regulations (CFR)
Part 1910, Part 1910.269, Part 1910.301-398, Part 1926 Subpart K, 29
CFR 1910.132(d) Hazard assessment; 29 CFR 1910.335(a)(1)(i); 29 CFR
1910.132(h)(1); 29 CFR 1910.132(f); 29 CFR 1910.132(f)(4); 29 CFR

As far as the final, this would challenging to study for. The
information presented is up to date with regards to current trends in
the photovoltaic industry from the presenters. Think the best
resource would be:
http://www.pvstudent.com/
And a discussion of each of the topics in the "Advanced PV Course
Notes ..."

Martin,
That is a useful study list suggestion, thanks. I find I would not be a good one to study with tomorrow, however. After I looked at my schedule, I find I have no time today to really study. I might be in better shape next week. Sorry, but I should back out for tomorrow.

With regards to Chapter 12, Utility Interconnection, there's
discussion at SolarPro with regards to inverters "tripping" on the
point of connection (NEC 690.64). Would like to make a brief
presentation tomorrow for class participation and maybe extra credit
with the emphasis of ground- and pole- mounted arrays and applicable
National Electrical Code (NEC) - Chapter 11. Have a a few questions
from a fun quiz and a few slides, and would be a short presentation no
questions. Again would be brief, and depending on the specific
situation, the differences in methodology.
Last week, there was a great presentation on Chapter 6, and batteries.
Looking forward to this week's guest !
In addition, from a previous class there was a discussion concerning
panels on two different orientations. And professor White indicated
in lecture there would be no reason he would install an array that
way. There is a discussion on the SMA forum [
http://forums.sma-america.com/ubbthreads.php?ubb=showthreaded&Number=1944#Post1944
]and although it's technically possible with a "Not ideal by any
means. Your system will use the lowest voltage and bring anything that
is higher voltage to the lowest common. Its the nature of Parallel
circuits. Although, the MPPT Unit does compensate for this a little.
Usually with differing orientations you can expect losses of around
1-5%." Therefore, although it would be technically possible, it would
not be ideal.
He indicated, with regards to roof mounted array, there are "expected
losses" with regards tilt and azimuth, instead of tilting arrays on
rooftops. As a result, flat with respect to the roof pitch. Therefore,
it would not be ideal, although it would be technically possible.
Both situations, non-technical as the answer. I'd concur with
professor White's thinking, do you agree?
How is the UIBB or Off Grid systems progressing, was there additional
thinking of a propane generator of a transfer switch as an
alternative. Had a diagram on how to attach the transfer switch with
a UIGD, think there is an issue if the neutral is unswitched, the
generator neutral should not be bonded ... Understand the requirements
for the battery system is 3kWh per day? Would you like to size the
ground mounted array for the requirements? With regards to the piers,
the method is to install 1 pier for every 2 modules of for a ground
mount, a top of pole mounted (TPM) would be different. There are a
bunch of calculations, but this is what it typically works out to in
our area.
If you would like more detail calculations suggest, but tend to exceed
slightly for Balance of Materials (BOM) discussions, (as the thinking
and discussion of using a #10 AWG instead of a #12 AWG on the DC
side.)
http://www.unirac.com/pdf/ula_config.pdf
Calculations could include snow, seismic, wind, ... maybe next week
for a study group - let's discuss. Concentrating Photovoltaics (CPV)
are also typically ground mounted systems, would you know any other
people using CPV besides KGO radio?
