Question 1

Are there fees associated with net metering?

Accepted Answer

Some utilities charge interconnection fees, standby charges, or grid maintenance fees for net-metered customers.

Question 2

Can net metering policies change?

Accepted Answer

Yes, policies and compensation rates can change depending on provincial laws, regulatory decisions, and utility company policies.

Question 3

Are there limits on the size of a solar system for net metering?

Accepted Answer

Yes, some utilities impose size limits based on your average energy consumption or state regulations. An assessment is done in order to determine the capacity limits.
Residential systems in Ontario are capped at 10 kW AC.  It is possible to do a larger system but this requires a costly capacity impact assessment (CIA).  CIAs are done for larger scale commercial solar systems.
