i have a 200A service and a generater system

Comments

Charlie,

Happy to shed some light on the subject.  The answer is not quite as easy.

This depends primarily on your roof space as to how much PV you can put on your roof.

The good news is, to my knowledge, MA does not have a limit as to how large your system can be.

On a 200A service you could have as much as approximately 7.6 kilo-watts of AC behind the main breaker

If your roof could support more than that, you can tap ahead of the main breaker before the meter to accommodate the larger system.

To get an idea of how many modules would fit on a roof you would measure the width and length of the roof facet you could install on.  Your average module is 65"Lx40"W.  This can give you the approximate amount of modules you can fit. 

To put that number in terms of system size, multiply your total number of modules by the wattage of your preferred module.

If you would like further assistance in determining how much you can fit, please feel free to contact me.

Adam,

It seems that the maximum AC power that could be connected to a 200A panel would be close to 7650W (7650/240*1.25=39.8A).

Thanks Jerry,  I did not go quite that far on that first brush answer.  I appreciate you're doing so and participating in this forum.
