Hi all,
I have a student who is looking for a solar thermal expert to look at an
ailing system in Anaheim, CA. Who could he call?

Hi y'all,
Since I haven't been doing layout/design recently, I wonder what
software I can recommend to a client. He is a newbie doing mostly
commercial systems - some roof and some ground mount. The software
needs to layout strings for string inverters, calc voltage drop,
conductor sizes,
Hi fellow wrenches,
Has anyone seen the new version of IEC 62446? I am wondering if they
added an entry for insulation resistance tests with an array voltage
above the ">500V" category.
Thank you in advance,

Even though they say Photovoltaic in the spec sheet, I am not sure that this

I've got several customers with them. I recently changed one from a 12V to 24V
system. I called and got right through to a tech. (Turns out you don't need
to change the light bulb - they use a 24V one for all 12/24V models.)

The light by the inverter is the only DC appliance I routinely recommend
nowadays in off grid homes and businesses, unless they have no backup
generator. If no backup, every electron counts, and there are some DC
appliances, in that case, that can be worth the price and fuss.

Hi Rebecca,
If you suspect the wires in conduit, you can megger just the wires by
disconnecting all the wires on both ends of the conduit, wirenutting them off
on one end, and meggering them on the other end. Megger between two of the
wires at a time, and repeat until all the wires have been
with it! Have flyers that list resources for
energy efficiency and energy conservation, as well as renewables. I'd
love to have a meter with a big readout that says how much power is
being used with a running total of energy. Project for the future...
