<DIV><FONT size=2 face=Arial>Hello Peter,</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>I should have noted that some of my DIY customers
include licensed contractors, mechanics, hands-on scientists, and engineers, as
well as skilled non-professionals. </FONT><FONT size=2 face=Arial>By
so-called professionals, I refer to sales engineers who are neither trained
sales people or engineers and contractors who do not know the skills that you
list. I make it pretty clear in the latest edition of The New Solar Electric
Home book that readers should seek experts and tell them how to identify
competent contractors.</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>Nevertheless, I will always encourage people
to learn how to protect and enhance their environment and themselves, to grow
their food, to make their clothes, to build
their home, learn how things work, and learn more skills. They may not
want to, or be able to, do everything for themselves, but they should not be
denied the freedom to be self-reliant.</FONT></DIV>

style="FONT-FAMILY: Arial; FONT-SIZE: 10pt">As a friend, I have enjoyed your
perspectives on our business, even though I usually don’t agree with
everything you say. I have never taken you to task in a public forum, but I
can’t let your latest post go without comment.</SPAN></FONT></P>

style="FONT-FAMILY: Arial; FONT-SIZE: 10pt">There is a reason we call these
guys DIYs. They have no experience and limited knowledge; in other words they
are not professionals. And, by the way, what do you mean by “so-called
professional”. I can’t believe you tell some one who wants to get into the
solar business to first put one on their home as a DIY. Could you in good
conscience recommend someone who has never stepped foot on a roof in their
lives to spend a week on one in 90-100 degree weather, in physical contact
with modules and other components that are cooking at 145 degrees, and DC
voltages approaching 600 V? Squinting at a layout/schematic the likes of which
they have never seen before? Someone who hasn’t used anything more than an 8
ft step ladder or doesn’t know what a safety harness is?</SPAN></FONT></P>

design engineer or a salesperson.</SPAN></FONT></P>

<P class=MsoNormal><FONT size=2 face=Arial><SPAN
style="FONT-FAMILY: Arial; FONT-SIZE: 10pt">I am personally aware of three DIY
solar projects as well as a dozen or so contractor-installed systems that we

worse than worst contractor-installed job. </SPAN></FONT></P>

style="FONT-FAMILY: Arial; FONT-SIZE: 10pt">But here is my main point. I have
a pretty good test of what is key in this PV business of ours. I get a call at
least once a week from some one who wants me to “help them with a PV
installation”. In addition to DIYs, I get these calls from B and C-10
contractors, facilities managers, apartment owners, and the like. They will
take care of [fill in the part that they think they have covered] and they
only need help with [fill in the part they need help on].</SPAN></FONT></P>

style="FONT-FAMILY: Arial; FONT-SIZE: 10pt">I agree. I have DIY customers
who know more about PV systems than a lot of so-called PV professionals.
Designing and installing PV systems is a continuous learning
experience. We are practitioners because, like doctors,
we practice our trade, expand our knowledge, and
hone our skills. I tell people who wants to get in the PV
business to put a PV system on their own
home. People who tell me that they want to sell PV
but can not go solar personally for whatever reason have less
credibility. They get less respect from prospective customers who
use the same reasons or excuses for not going solar. They either
don't last long in the business or are in it only for the money. Granted,
there are less operational nuances to a batteryless, grid-tied PV system than
a battery-based system or wind or water generator, but living with your
work is essential. It makes you keenly aware of unique subtleties and
helps you better understand your customers concerns.</SPAN></FONT></P></DIV>
