Is a 5kW Solar System Right for You?
A 5kW system is the sweet spot for growing families and households with above-average electricity consumption. With 4,250 kWh of annual generation, it provides meaningful surplus for EV charging, battery storage, or export income.
Ideal for
- 3-4 bedroom family homes
- Households using 4,000-5,000 kWh per year
- Homes with or planning an electric vehicle
- Families wanting to future-proof their energy supply
- Properties with heat pumps or high hot water usage
EV-Ready Solar
One of the key advantages of a 5kW system is its ability to contribute meaningfully to electric vehicle charging. On sunny days, the surplus generation can add 30-50 miles of EV range. Paired with a 6-8kWh battery, you can charge overnight using stored solar energy rather than expensive grid electricity.
Cost vs Value
At C$12,000 - C$17,000, a 5kW system costs roughly 15-20% more than a 4kW system but generates about 25% more electricity. This makes it excellent value per kWh, especially for households that can use most of the energy produced. With savings of C$450-C$700 per year plus C$80-C$180 in export income, payback is typically 8-11 years.
Battery Pairing for 5kW Systems
A 6-8kWh battery is the ideal pairing for a 5kW system. This allows you to store surplus daytime generation for evening use, increasing self-consumption from around 40-50% to 70-80%.
