Can I put in a grid-tied solar system larger than my usage?

In Alberta there is something called the Micro-Generation Regulation. This regulation is intended for small scale home owners, small businesses, municipal and community buildings to become self sufficient. It states that a PV system is intended to meet all or a portion of a customers electricity needs. Normally this means using the last year of electrical consumption (from the bill) however a system may also be sized with an anticipated load. If an individual is looking to purchase a hot tub or AC unit or even an electric car, this can be accounted for and offset with solar PV.


​While they can be more difficult to get approved, systems that produce more than the home consumes can have a larger affect on the electrical bill.
