We love Morningstar 60mppt for lower end solar, ethernet ( no security )

for a serious amount of solar. For bigger the 600Volt is available,
for bigger than that the signature solar controllers will do about

Surprisingly, not a lot. 10-15% which in line with their summer
production. Winter with snow, people were reporting production 20-25%
higher and much higher when the panels are covered with snow behind and
sunlight there were videos of 20% production when regular panels were
zero. This was
Two methods I didn't mention that this group might already be familiar with:
1) They still distribute time via telephone. Call 303-499-7111 to hear
the WWV (colorado) broadcast or 808-335-4363 for WWVH (hawaii)
2) You can dial in with your dialup modem and get time codes. 300 baud up
to 9600
That’s building strictly for a 20W load though. Building for a tiny load does
make the costs easier. But if you wanted a second AP, bigger backhaul, or
anything else you can’t do it without growing the whole power system
proportionally.
Steve was talking a 50W load today. The real high
I set up a CO2 powered deicing system once. It was kinda successful. My
business partner published pictures of it and we instantly had BLM cops saying
we were dumping antifreeze.
Yes we were but it was propylene glycol. They didn’t care. I told them that
their own BLM aircraft use this
I presume they are more expensive? Is the watts per square foot the same?

I'm at about the same latitude as you. My experience is that having extra

probably go with Chuck's numbers for batteries if I was putting something

I end up closer to Chuck’s estimate. In Southern or Central NY State I’m 2
degrees north of Salt Lake City. 42N
What’s your latitude?

We had a storm blow a set of panels over so they were pointed down. They
were 10 feet off the ground and we were getting significant power from the
sunlight reflected off the snow.
If I was going to build another system that is super critical, and
unaccessible in winter, I think I would
Yeah, that's what I'd do in a difficult to access location. I did a site
like that here (Wisconsin) with 200 watts of panel (I think the actual load
is around 15 watts, so a bit more than 10x), and ~4kwh of battery. It had
some issues in January a couple years, but I attributed that more to using
When not buried in a historic snow load or positioned correctly so that
the snow falls off the panels and a 200 foot cliff...

Using my historical rules of thumb for off grid, snowed in mountain top
location for a 20 watt load I would do the following that has never failed me:
Load X 20 so 400 watts of panel. So less than $200 these days.
2 weeks of battery autonomy.
20 x 24 x 14= 6720 watt hours. $2K of batts
It depends on how much stuff you're trying to run. A minimal micropop can
be done with less than 20 watts of load (single AP and backhaul). I can put
together a solar setup for around $1000 that will power that.

Definitely worth asking about.
They have done unmetered service here in the past for CATV amps, but I think
NYSEG told us they aren't doing any new ones.
