Solar Savings Scenario: 12kW Solar Power System with a 20kWh Battery
For homeowners looking to maximise the benefits of installing a 12kW solar power system paired with a 20kWh battery, understanding the ideal energy consumption is key to maximising savings. A 12kW solar system can produce significant energy, and when combined with a 20kWh battery, it allows you to store excess solar power for use during non-sunny periods. This analysis will explore the ideal daily energy consumption that maximises the value of this solar and battery setup, focusing on optimising both direct solar use and battery storage.
System Overview
- Solar PV Capacity: 12kW
- Average Daily Solar Generation: 12kW x 4.2 kWh/kW = 50.4 kWh/day
- Battery Storage Capacity: 20kWh
- Electricity Tariff: $0.40/kWh (grid electricity cost)
- Feed-In Tariff: $0.05/kWh (for excess solar exported to the grid)
Ideal Daily Energy Consumption for Maximum Savings
To fully utilise a 12kW solar power system with a 20kWh battery, the ideal daily energy consumption should align with the energy generation and battery storage capacity. The goal is to consume as much solar energy as possible during the day and store the excess for night-time use. Here's how the energy breakdown works:
- Direct Self-Consumption: The energy your home uses directly from solar during the day.
- Battery Storage Use: The energy stored in the battery during the day, which is used later when the sun is not shining.
- Excess Energy Exported: The energy not consumed or stored, exported to the grid at the feed-in tariff rate.
Ideal Energy Breakdown
For maximum savings, the ideal daily energy consumption should aim to balance direct solar usage and battery storage, while minimising the amount of energy exported to the grid at the low feed-in tariff. Here's an optimal scenario for energy use:
Direct Solar Consumption
- Direct Self-Consumption Target: 30-40% of daily solar generation used immediately during the day.
- Direct Energy Usage: 30-40% of 50.4 kWh = 15.12 to 20.16 kWh/day.
Battery Storage Use
- Battery Capacity: The 20kWh battery can store a portion of the excess solar energy during the day.
- Excess Energy Stored in Battery: After direct use, the excess energy is stored in the battery. Assuming ideal usage:
- Excess Energy Available for Storage: 60-70% of daily solar generation.
- Excess Solar Generation: 60-70% of 50.4 kWh = 30.24 to 35.28 kWh/day.
- Battery Storage Capacity: Since the battery capacity is 20kWh, it can store up to 20kWh/day.
Total Self-Consumption (Direct + Battery)
The total self-consumption includes the energy used directly during the day and the energy drawn from the battery at night.
- Total Self-Consumption: Direct (15.12-20.16 kWh) + Battery (up to 20kWh) = 35.12 to 40.16 kWh/day.
Excess Energy Exported to the Grid
Any energy that exceeds your direct consumption and battery capacity will be exported to the grid at the feed-in tariff rate. In this case:
- Excess Energy Exported:
50.4 kWh (total solar) - 35.12-40.16 kWh (self-consumption) = 10.24 to 15.28 kWh/day exported to the grid.
Financial Analysis
1. Self-Consumption Savings
- Electricity Tariff: $0.40/kWh
- Daily Savings from Self-Consumption:
- Low Estimate: 35.12 kWh x $0.40 = $14.05/day
- High Estimate: 40.16 kWh x $0.40 = $16.06/day
2. Earnings from Feed-In Tariff
- Feed-In Tariff Rate: $0.05/kWh
- Daily Earnings from Feed-In Tariff:
- Low Estimate: 10.24 kWh x $0.05 = $0.51/day
- High Estimate: 15.28 kWh x $0.05 = $0.76/day
3. Total Daily Benefit
- Low Estimate Total:
$14.05 (self-consumption savings) + $0.51 (feed-in earnings) = $14.56/day - High Estimate Total:
$16.06 (self-consumption savings) + $0.76 (feed-in earnings) = $16.82/day
Annual Savings
- Low Estimate Annual Savings:
$14.56/day x 365 = $5,313.40/year - High Estimate Annual Savings:
$16.82/day x 365 = $6,139.30/year
Why Choose a 12kW Solar Power System with a 20kWh Battery?
- Maximised Self-Consumption: The combination of a 12kW solar system and a 20kWh battery allows you to use up to 40kWh/day of self-generated energy, significantly reducing your grid reliance.
- Substantial Financial Savings: Depending on your energy usage, you could save between $5,313 to $6,139 per year on electricity bills.
- Energy Independence: With the ability to store up to 20kWh of excess solar energy, you can power your home during the night and reduce your reliance on expensive grid electricity.
- Reduced Carbon Footprint: By using more of your own renewable energy, you lower your environmental impact and contribute to a greener future.
Ideal Daily Energy Consumption.
To fully optimise a 12kW solar system with a 20kWh battery, your ideal daily energy consumption should range between 35 to 40kWh. This ensures that you’re using the maximum amount of solar energy while still storing enough in your battery to power your home during non-solar hours.
