Why Choose a 10kWh Solar Battery?

With electricity prices soaring in NSW, a 10 kWh solar battery (often searched as a “10 kW solar battery”) paired with a 6.6 kW solar system is a smart choice for energy independence.

This battery stores excess solar energy generated during the day to power your home at night — reducing your reliance on the grid and protecting you against blackouts.

  • Meets Average Needs: The average NSW household consumes 15.5 kWh/day, with peak usage from 4–9 PM. A 10 kWh battery covers nighttime needs for most homes.
  • Backup Power: Provides emergency power during grid outages, ensuring energy security.
  • Cost Savings: A 6.6 kW solar system produces ~25 kWh/day to power your home and charge the battery.

Battery Sizing

Is a 10kW Solar Battery Right for Me?

When deciding if a 10 kWh solar battery is the right size for your needs, there are several factors you need to consider:

  • How much electricity (in kWh) does your household consume each day? Check your electricity bill and compare all four quarterly bills to see seasonal changes in usage.
  • Try to estimate how much power you use at night. During the day, your solar system powers the home, and any excess generation fills the battery. This stored energy then runs your home at night.
  • According to the Australian Energy Regulator, the average daily household electricity consumption in NSW is 15.5 kWh per day.
  • More energy is typically consumed in the early evening hours between the hours of 4 PM to 9 PM.

With these factors in mind, a 10 kWh solar battery is adequate for most average households at night. If you need more capacity, SolarBright offers several modular systems that can be expanded to suit your needs.

What Size Solar System Is Needed to Fill a 10kWh Solar Battery?

Your solar system must generate enough power during the day to meet household consumption and still have excess energy to charge the battery.

According to the Clean Energy Council (CEC), a typical solar system in NSW produces about 3.9 kWh of electricity per day for each 1 kW of system size, averaged across the year.

That means a 6.6 kW solar system will have an average daily output of 6.6 × 3.9 = 25.74 kWh per day in NSW.

Production varies seasonally — higher in summer, lower in winter — but on average, a 6.6 kW system easily covers 10 kWh of daytime use, charges the battery, and still exports around 5 kWh to the grid.
