Dellta LA lightning arrestors would not prevent the diode damage
you mentioned. I think many others on the list will confirm that
Delta LAs are not effective at preventing equipment damage, and
probably only useful in preventing complete wire melt down. Midnite
found the Delta didn't start clamping till well over 2000 volts.
It might be coincidence, but we have not a single case of lightning
damage since we switched to the Midnite SPD protection. The Delta
isn't even UL listed anymore.<br>

I concur with your “Wow” comment about Panasonic performance. I
have never found any module to outperform them except for
Uni-Solar. It’s sad that both products are no longer available.<br

class="">We did a run of Sanyo modules for a few
years. Last year one of our HIT 195 BA3 arrays of 12
started losing production, a 2005 system with the
fabled SMA SB2500U. the warranty process was really
intense, a lot of photos per module required, and much
documentation. To no avail, as Panasonic came back
with the science showing how lightning took out the
blocking diodes at various degrees through the years?
We had this well-grounded, 600 VDC RK5 fused, Delta LA
DC602, and more. So in the end we asked the client to
see if the homeowner’s insurance might come forth. Yes
they did! We just replaced the array with Panasonic
HIP 240’s and Apsystems YC500 micro inverters, wow!
This system rips, showing 270 watts per module in our
cold climate! The Panasonic’s were acquired from
CivicSolar, good people to work with! <o:p class=""></o:p></span></div>
