look more closely at the manufacturer's printed warranties. I am curious
what you think of these two warranty exclusions --<br><br><div class="gmail_default" style="font-family:arial,helvetica,sans-serif;display:inline">(</div>Excerpt from <div class="gmail_default" style="font-family:arial,helvetica,sans-serif;display:inline">a module manufacturer's </div>warranty quoted here:<div class="gmail_default" style="font-family:arial,helvetica,sans-serif;display:inline">)</div><br><br>" The Limited Warranties do not apply to any of the following:<br><br>-
Damage caused by nonuniform sunlight on the PV modules produced by
artificially concentrating sunlight or excessive shading of the PV
modules.<br><br>- Product which has been moved from its original place
of installation (including but not limited to any installation,
application, repair, servicing, or temporary removal) by any party not

manufacturer deems the site unsuitable because of shading? Of course we try to put modules
in full sun, but what is excessive? Shading from a dormer? A higher roof
shading a lower roof part of the day? Uneven snowshed? (This would also stress bipass diodes, but is of course out of our control)<br><br></span></font>The
second item would imply that removing and reinstalling the array for a
re-roof would void warranty unless we got an authorization in writing
from the manufacturer? Not that the manufacturer would necessarily know,
but still.
