I have a big house with various sub-panels. Do I need one for each panel or just in the main/first panel?

I have a main panel which feeds a generator transfer panel. I put the sycom on the main panel only.

As far as I know if all sub panels are fed for the main panel you would need the one but if they are fed from the main supply directly you would need one in each.

No you do not. You only need the one supplied with camera "kit." The whole system runs off of your electrical box. All the circuits run back to the main breaker panel. In one installation, although it was the same business, they had two breaker panels, so I had to run a plug off the one panel I was connecting the system to. It worked well. Good luck.

UHM Are you sure you need that much power in 1 month? I use 300kWh at most at my house. Assuming you mean average over a year and not 2,400kWh worse case, you would need around a 25kW array. This also assumes the system is facing south and not obstructed by trees. This is a large system and you would need 174 panels. Typically a residence has around a 5kW array so yours would be 5 times larger.

yes - each panel can be removed from the rest - so you can add as many as you want.

you need 2 mc4 t connectors per 2panels to hook together so if you get six you will need 8 pus 3 for a total of eleven; for just instance i have 4 panels w/ 4 mc4 t connectors plus one to connect the four into one line you have to hook all panels into one line

Yes, your two panels should have less than 20 amps output, under the best conditions. They should put out about 7.5 amps each, equaling 15, well within the 20 handled by the controller...

No, you only need one. Please check out this video for more detail. https://www.youtube.com/watch?v=0Fs6v3rvuuk

either set, it does not matter. It is designed to be used as either a standalone or pass-though base, the second set will feed this lamp as well as the first set would. The electricity doesn't care. Just pick a screw on either side for each wire, don't put both wires on one side! :)

Yes, but one will be missing a panel. I did this, but left the bottom panel empty. It works just fine.

You need the id number of each of the panels which the installer should provide you free of charge. It on each of the panel's label.

Yes. I bought two of these and add them all together. But I do not think you can just buy extra panels. You need to buy a whole new set to add on.

Yes. You will need one a least. Six or eight is not out of the question either because, this will give you more electricity into the evening hours.

yes, you can use 3 or 4. I am also just using three, but it's nice to have that extra panel in case I want to use it somewhere else.

No. There is a connection to the regulator. There is no other way to connect to another panel. This panel is not strong enough for even one lousy 12 volt light bulb.

Nope one is all you need. I pivot the rolled up solar blanket on a home made prop. Works great.

I'm afraid you need four, one for each panel. At least in our installation, each panel needed a separate feed to the controller.

You don't need any, the panels should come with the connectors sufficient to wire them in series or parallel. If the panels don't come with connectors, buy better panels. The only time you'll need connectors is if your array needs additional wire to get a run to a junction box. Once the array is connected, anything past that is going to be or should be heavier gauge wire unless the run is very short and the voltage is high (series connected array).
