Solar in Whitehorse typically pays back in 10 years for a right-sized 6 to 10 kW residential system. Payback varies with your ATCO Electric Yukon rate (average 12.0¢/kWh), 1,840 annual sun hours in Whitehorse, net system cost after Yukon rebates, and how much production you self-consume.

How Whitehorse Solar Payback Is Calculated
Payback (years) = Net System Cost / Annual Bill Savings
Net system cost is your installed cost minus available rebates. Annual bill savings equal annual production times your effective rate, adjusted for self-consumption. In Whitehorse, we use 1,840 sun hours, 11% capacity factor, ATCO Electric Yukon rate 12.0¢/kWh, and 85% self-consumption.
Assumptions used on this page
- • Installed cost mid-range: $4.30 per watt
- • Annual production: 11% capacity factor times 8,760 hours per year
- • Electricity rate: 12.0¢/kWh flat (does not model TOU or ULO)
- • Rebate: None modelled (some provinces have utility credits or municipal financing)
- • Self-consumption ratio: 85%
- • No rate escalation modelled (real payback is shorter with rate increases)
