The money

Program	What it's worth
Clean Technology ITC	30% refundable (20% without labour election)
CCA	Classes 43.1 and 43.2
Storage	Qualifies alongside solar

Sizing to your load

Solar cuts energy; batteries and load control cut demand. The right mix depends on which line is bigger on your bill.

Farms

Incorporated farms are eligible for the ITC. Farms claiming personally are not.

What to have ready

12 months of bills, and interval (hourly or 15-minute) data from your utility if you can get it.
Your rate class or rate code.
Whether the business is incorporated and taxable. That decides the 30% credit.
Roof age and condition, or the spot you'd use for a ground mount.
Any expansion plans that will change your load in the next few years.

Questions to ask any installer

Have you modelled my interval data, or just my monthly totals?
Is the price shown before or after the federal tax credit, and does it assume the labour election?
Which line on my bill does the system reduce: energy, demand, or both?
Who handles the utility connection application, and how long does it take here?
Has the roof or ground mount been checked by a structural engineer?

How business power is billed

Almost every Canadian utility bills businesses on three things: a fixed charge, energy per kWh, and, once you're big enough, demand per kW. Thresholds vary by province.

Province	Where demand charges start
Ontario	Distribution demand charges on larger (Class B and A) accounts
British Columbia	35 kW (Medium General Service)
Alberta	Depends on wire owner; none for small business with ENMAX or EPCOR
Nova Scotia	32,000 kWh/yr (Rate 11)
New Brunswick	Above 20 kW (General Service I)

Where solar fits

Solar cuts energy. Batteries and load control cut demand. The right mix depends on which one is the bigger line on your bill.
