Hello,<br>
<br>
I'd like to propose we allow spending of up to $2k to cover the
costs of installing a photovoltaic (solar) power system @ Haystack.
The site owner has allowed us to host a site up there as long as it
doesn't impact their power budget. The site is not wired to any
utility power, and transporting propane to it is expensive. This is
a 1-time cost, and the hardware will remain property of the site
owner. In exchange they'll be giving us new mounting points for 2
dishes and 2 sectors, which will have a huge impact on coverage and
extending the network. Our recurring cost for the site will be
$0/mo, which is an ideal long-term arrangement.<br>
<br>
Here is a list of the hardware required:<br>

<br>
In the $2k request, I'm also allowing ~$250 for shipping costs.
Solar panels are large. Anything not spent will be returned to
the HamWAN budget.<br>
<br>
We already have all the other hardware required to deploy the site
in-stock. Some of it is already deployed (Haystack-S3), and some
is sitting on-site (modems, 1 dish, other sector).<br>
<br>
Our present balance is $1,291.04, so we'd be going into debt for
this deal.<br>
<br>
The other cost of this deal is recognizing the site owner's
sponsorship of HamWAN by including their logo in presentations,
and offering some man-hours for site maintenance. The big project
this summer (aside from this solar system install and the full
HamWAN site install) will be helping with installing a grounding
system there.<br>
<br>
My vote on this deal is: YAY.<span><font color="#888888"><br>
