Most net metering arrangements require a manual power disconnect switch for your rooftop generation [1] for utility workers or first responders, and NEC requirements require inverters to shut down ("rapid shutdown") if they can't sync to the utility to prevent backfeeding power during maintenance (caveat: if you have local energy storage, the inverter will island and continue to provide power from local storage). I would encourage you to ask your municipality and their utility department what their net metering arrangements are; I would be happy to make such a phone call/inquiry on your behalf if you would prefer.

Is your utility Nova Scotia Power by chance? It appears they support net metering [2].

Everything I mention above will be cheaper than storage (which will start around $13k CAD).
