Show transcript
Take a picture of how you look exactly, I'm gonna replace this section here hopefully. Let me see. Alright, good. Because they don't have no bolts, holding in the center so we lock it. So all we have to do is just take a picture of everything. Get the detail with your camera. Alright, so we got that. There we have things here, get the picture of how we look right here. So all of this is still normal, everything only just up here are really the same aspect.

Field access and activities depend on project availability, client authorization, safety requirements and the participant's experience level.

Close-up work inside an open enclosure, checking and tightening wire terminations before the cover goes back on.

Learning objective Understand why termination tightness is checked and confirmed before an enclosure is closed out.
Show transcript
[unclear] this one is 842.2kw. [unclear] Same thing, same thing, yeah that's probably the difference thing here. Alright so everything here, make sure the double check on the termination, just make sure everything tight. One two three, neutral, ground, wire this here, positive section over here. Everything set this is done tight. So we're done, alright let me flip back on the covers, let me just put on this cover here.

Identifying a Community Solar Meter and Circuit

A close look at a utility meter and its tag, and the labeled circuit that connects a community solar system to it.

Learning objective Recognize how to identify and distinguish a community-solar meter and circuit from a building's main service equipment.
Show transcript
[unclear] So now, what we could do, we could log into it. [unclear] So, what the system is that it has two systems. [unclear] There are three over there, that is the one called the community solar. [unclear] Meaning that it connects behind in front of the meter. [unclear] So this is the meter here. [unclear] You can see the tag, [unclear name] meter. [unclear] And it lock and you see this is the solar circuit. So you come in here, distribution in here, it could be a city cabinet. City cabinet, got two different service, so you have two different things here, but this is the one that connect from the solar and this is the one over here. So this is a city cabinet for this meter, this is a city cabinet for this meter over here.

Reading Disconnect and Interconnection Labels

A walkthrough of a generator disconnect switch's rating and interconnection labeling, and how to tell whether it is fused.

Learning objective Learn how to read disconnect and interconnection labeling as part of an equipment walkthrough.
Show transcript
[unclear] Disconnect inside of here and then go out, come into this meter base, this is the meter for the solar that community solar come in, come out, come up into the disconnect. Remember the lines are, you most I get the wire then I come up this way into the line side, come to, now you can look and see okay what kind of, this is the 89L, is it the first means the disconnect because of the 89L. So from here now you can actually see what size thing, then it's supposed to be from here, the size thing, if it's like a fused one or not. I don't see any identifying things in it, basically just tell you PV meter, it just tell you everything is that. So it does basically manual visible gun operated load brake lockable.

Tracing DC Conductors From Roof to Combiner

Following cable routing from the inverters, distinguishing AC and DC runs, and tracing PV wire up toward the roof.

Learning objective Recognize how to visually distinguish and trace AC and DC conductors between roof and ground-level equipment.
Show transcript
So then you come over here, come in, and this point here look like what they used to distribute out, because this feeds these inverters here, see the cable come out of this box. And you can actually trace everything and see where it come from, and then this here get this power. Okay so this here belong, look like it belong to the building. So you can see we tie from here, main distribution channel, this is tie here, you get this power on the box here. So this and this, this is probably AC, and this is most likely to be the DC, the DC cable going up to the roof. Yes, I'll end up having PV wire that go up to the roof and go out that way. Okay, I had two set of wire.
Inspection & Assessment

Learning What to Observe

Field development includes learning how to observe system conditions, document findings and distinguish between a visible concern and an issue that requires further testing.

Using a Thermal Camera During a Site Walk

A technician opens an enclosure and uses a handheld thermal camera as part of a site walk.

Learning objective See how a thermal camera is used in the field as part of a visual equipment check.
Show transcript
We have a flat tip here. Let me just open this box, let me see something. Now let me open the box up, let me just check this in right over here. Scan it in. Let me first turn it on. So the middle cabinet, cold. So trying to turn it, that's where I first walk on the T-gun. Thermal gun. Wait, is it? A little bit.

Learning objective Recognize power-cycling as a first troubleshooting step for a non-communicating device, before escalating further.
Show transcript
[unclear] I think we might have to go inside to [unclear] the modem, to do our test driving. So let me get the [unclear]. Alright so we are on the on, give it some time for it to cycle and see what it is. Give it some time and then that.
1:22

Comparing Repair Approaches and Checking System Status

Two technicians discuss a prior repair that required a larger section change, then check a status screen to evaluate the current situation.

Learning objective See how field technicians reason about repair scope and choose an approach that avoids unnecessary work.
Show transcript
[unclear] Remember the last time when we worked, we had to change out this whole section here. Imagine if we had to change out that whole section, you need this way to make it much easier. [unclear] At first when they sent the other thing, they said that it won't work, but this one doesn't work. We'll make sure. Okay so now you see it ready, all the [unclear] are on the ground, we'll go that way. And then that thing we're going to do is login and see what's going on there again now. So we're going to login to this one, and we're going to login to this and see what it says.

Show transcript
So what it is, the field coming in, coming in from, the field may be coming in from here. [unclear] This is solar, you can see it label here. But the only way you don't know is if you open up this here. Where it come in for feed the building, so you have your meter, so this here come in here. Look at the size, you have the size of the building, you don't know this belongs to the building. This is something else because you can't admit on it, it measures something else, and it might be something else, that might be for the solar. Let me see if it's the owner. Okay, this is the owner meter, owner lower level. So this is your solar circuit, then don't label it and tell the source, say, don't know this here or what you work with here. This is nothing for you to touch. This and the meter are how we measure the current for the building. So you're gonna touch them from here. Everything now come from this section here.
Why This Resource

Training Built from Active Field Work

Most solar training content is written by instructors, equipment manufacturers, or certification bodies: people who are not currently conducting commercial inspections in the field.

Wadadli Solar's career development content comes directly from active commercial inspection and O&M work on NYC and Tri-State area systems. The workflows, documentation standards, and diagnostic approaches taught here are the ones we use on actual jobs, not generic educational frameworks.

NYC commercial solar has specific characteristics: dense rooftop installations, primarily flat-mount systems, SolarEdge and SMA platform dominance, and building ownership structures that require clear technical communication to non-technical stakeholders. This context is built into every part of the curriculum.
