Fire lookouts, Repeaters, Cell towers, ect\u2026. Cascade and Coastal Cement. I count on arrays at 60 degrees getting entombed in snow and ice for weeks. I\u2019ve seen the walls of most buildings encased in ice too! Lookouts get shut down for six months, and maybe minimal loads stay on, like weather equipment. When full time power is required, then propane or diesel generators and room heaters are installed, often tandem generators that alternate usage and act as backups. Many of my previous customers required a rapid response if there was a power failure and that meant serious adventure. I\u2019m kind of over it now, many of those clients technicians also take care of the power end of things.</div><div class="">Michael</div><div class=""><br class=""></div><div class=""><div><blockquote type="cite" class=""><div class="">On Dec 1, 2018, at 2:18 PM, Sam Haraldson <<a href="mailto:sam@onsiteenergyinc.com" class="">sam@onsiteenergyinc.com</a>> wrote:</div><br class="Apple-interchange-newline"><div class=""><div dir="ltr" class=""><div class="gmail_quote"><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">However, even if vertical, will Sierra snow (its a special breed) still <br class="">

Even the wettest Sierra stuff sure doesn't seem like it could stick to glass at a 90 degree angle. I suspect you could get away with 60 deg, have better production, and still shed the snow. </div><div class=""><br class=""></div>-- <br class=""><div dir="ltr" class="gmail_signature" data-smartmail="gmail_signature"><div dir="ltr" class="">Sam Haraldson, Installation Manager<br class=""><a href="http://onsiteenergyinc.com/" target="_blank" class="">onsiteenergyinc.com</a></div></div></div>
