The size of solar panels you need totally depends on your climate and
location. For a rough calculation you can use pvwatts:
You say you have a 50W constant load. First figure out your kWh per month.
(50 x 24 x 31) = 37200 Wh, or 37.2 kWh per month consumed.
Using Seattle as an example location,
According to a friend of mine "Anything can be built."
We have several solar sites, and when they have enough battery and
panels, they are every bit as reliable as utility power. In fact, one
site we have had installed for 4 years without a single power issue. Our
older sites have had some

Depending on where you are, you may want to consider a grid-tie system.
Let's assume $400/month @ 10c per KWH. So 4000kWh/month. 133kWh/day.
Assuming 5 hours of sun, you need 27kW of panel.
Solar panels are about a dollar a watt

Most regular sized panels are about 280 watts.

Ken,
This is exactly the other option we are considering. 48v (or 24v, since we
already have 24v as the standard in our network) up the tower, with Transector
protectors on each end, and a RSD to provide some isolation after
That typically is done at the service panel in 95% of the cases, as far as I
have seen.

OK, so I am working with a grounding expert today, getting some opinions on a

I would at least allow 7.5W per ePMP radio (specs say 7.5 is typical, can
spike to 10), and 10-15W per 320. Maybe another 5-10w per MT radio. That
would be close to 100W. You don't want to underestimate power consumption.
