A properly sized and installed solar system can provide 60-90% of your hot water needs from free solar energy. Read our complete guide to solar hot water in Perth for detailed information on system types and installation requirements.

Types of Solar Hot Water Systems
Flat Plate Collectors
- Traditional proven technology
- Durable and long-lasting
- Good for standard installations
- Lower cost option
Evacuated Tube Collectors
- Higher efficiency, especially in cooler weather
- Better performance when partially shaded
- More expensive but more effective
- Popular choice for Perth homes
Split Systems
- Collectors on roof, tank at ground level
- Easier maintenance access
- Good for homes with limited roof structure
- Flexible placement options

Is Your Roof Suitable?
For optimal solar hot water performance in Perth, you need:
- North-facing roof section (east/west works but less efficient)
- Minimal shading from trees or other buildings
- Structural strength to support collectors and tank (if roof-mounted)
- Adequate space for collector size matched to household needs
Solar vs Heat Pump
Both are excellent energy-efficient choices. Here’s how to decide:
| Factor | Solar | Heat Pump |
|---|---|---|
| Roof needed | Yes | No |
| Works in shade | Poorly | Well |
| Cloudy days | Needs boost | Works well |
| Running cost | Very low | Low |
| Upfront cost | Higher | Lower |
| Maintenance | Annual check | Minimal |
Boosting Options
All solar systems include a boost element for when solar heating isn’t sufficient:
- Electric boost - Most common, simple and reliable
- Gas boost - Lower running cost but requires gas connection
- Heat pump boost - Maximum efficiency but higher initial cost
In Perth’s climate, most households find their boost only activates in winter or during extended cloudy periods.
