Net metering quality

Quality of net metering policy (higher = better for solar economics):

Fair — Net metering (Hydro Ottawa)

What this means

Fair net metering policies pay less than retail for exports. Consider self-consumption or a battery.

Example: 900 kWh/month household in Ottawa

At 4.0 peak sun hours and a 400W panel, you'd need approximately 21 panels (8.4 kW system) to cover your usage. That produces ~10,547 kWh/year, saving about R1,582/year at the 0.15/kWh local rate.

Going solar in Ottawa

Ottawa, in Ontario, Canada, has 4.0 average peak sun hours per day — good for solar. The local electricity rate is R0.15/kWh, below the Canada average.

Net metering in Ottawa is rated fair. Net metering (Hydro Ottawa). This significantly affects solar payback: with excellent net metering, every excess kWh you produce is credited at full retail value; with poor net metering, exports may be worth only 10-30% of retail, making battery storage much more attractive.

Available incentives include: Canada Greener Homes Grant. These can substantially reduce the upfront cost of solar and battery installations. Note: the US federal solar tax credit expired December 31, 2025. State and local incentives still vary by region. South African taxpayers can claim accelerated depreciation under SARS section 12B.

Next steps

Use the Solar Panel Sizing Calculator with 4.0 peak sun hours to find out exactly how many panels you need. Then check the Solar Savings Calculator for a 25-year projection using the local R0.15/kWh rate. If net metering is poor in Ottawa, also run the Battery ROI Calculator — batteries may be essential rather than optional.
