Where Your Savings Come From
Your total savings are a combination of three factors:
1. Direct Savings (Reduced Purchases)
This is the biggest saving. Every unit (kWh) of electricity your panels generate and you use instantly replaces a unit you would have had to buy from your electricity supplier.3 Since solar electricity is essentially free after the initial installation cost, this is pure saving.4
2. Export Payments (Selling Excess)
When your panels generate more electricity than your home is using—which often happens on bright days—the excess power is automatically exported back to the main grid.5 Under the Clean Export Guarantee (CEG) tariff, your energy supplier will pay you for this excess power, providing an extra stream of income that further reduces your net bill.6
3. Protection Against Price Hikes
Every unit of power you generate yourself is a unit you are protected from future utility price increases. As energy costs fluctuate and generally rise over time, the value of your free solar electricity also increases, meaning your savings actually grow each year.7
🔑 Key Factors That Determine YOUR Savings
Because every home is unique, the actual figure depends heavily on how you design and use your system. This is why a bespoke consultation is so important!
| Factor | High Savings Scenario | Low Savings Scenario |
|---|---|---|
| System Size | A larger system (e.g., 5kWp+) that meets most of your usage. | A very small system that only covers a fraction of your needs. |
| Battery Storage | Yes. You store daytime excess to use at night, achieving high self-consumption. | No. Excess power is exported and bought back at night (at a higher rate). |
| Daytime Usage | High daytime usage (e.g., working from home, running heat pumps, charging an EV during the day). | Home is empty during the day, meaning most solar power is exported. |
| Roof Orientation | South-facing roof with zero shading (maximum generation). | North-facing roof or heavy shading from trees or chimneys. |
A trained consultant will analyze your specific electricity bills and roof space to give you an accurate, personalized savings projection.
