<p>I would not go DC for starters. I lived with a DC fridge for
years and would not wish that on anyone in the 21st century.
Regular Energy Star rated models are very close to the Sunfrost
energy numbers, but are much cheaper, are readily available, and
can be serviced by regular appliance repair folks.</p>
<p>On the module type/ price, we switch to much lower cost 60 cell
modules at around 300 watts these days, and use an MPPT
controller. We're only using 12 v modules for very, very small
systems. <br>
</p>
<p>As far as small power packages, we've always built are own. Goal
Zero is more portable/ backpacking stuff; I have a fold up 5 w
Module from Goal zero that can charge a cell phone while camping.
They're great for stuff like that, but they're going to be way out
of the budget for a permanent mounted larger system.</p>
<p>Contact us offline, if you want, we could possibly help put
together a low cost package system for this application. Not many
solar companies want to mess with sub Kw systems these days, but
there certainly is a need, as you've found. <br>
</p>
<p>Thanks,<br>

<p class="MsoNormal">We are working with Turning Point
Foundation a 501(c)3 to provide off-grid power for their River
Haven project which is providing transitional housing for
homeless folks in the Ventura CA area.</p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">The site is truly off-grid and currently
uses propane to power three refrigerators and cook stoves.
There is no space heating for the single occupancy rooms as of
yet. But that\u2019s another problem.</p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">We are looking to specify DC refrigerators
and PV-powered battery storage for the River Haven project. We
are looking at the Goal Zero Yeti-3000 system (3000 Whr, 500
full discharge cycles, to 80% residual capacity) at a sale
price of $2,400 but are finding the extra cost of their PV
modules quite steep. And looking at other 36-cell (12 volt)
modules, I can\u2019t find anything for less than $1.10/W. </p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Since Goal Zero is looking at the
recreational market, I thought that there might be other
companies with comparable product offerings that are focusing
on other markets like developing countries.</p>
