Common Solar Mistakes to Avoid
Choosing Cheapest Quote
WHY IT'S BAD:
Lowest price often means inferior components or rushed installation
DO THIS INSTEAD:
Compare quality, warranties, and installer credentials
Oversizing System

Size based on actual usage and future needs
Ignoring Roof Orientation

Poor placement reduces energy production significantly
DO THIS INSTEAD:
North-facing ideal; east/west acceptable; avoid south
Not Considering Battery

Adding battery later costs more than installing together
DO THIS INSTEAD:
Install battery-ready inverter even if battery comes later

Quick Tips for Smart Solar Shopping
Practical advice to ensure you get the best deal
Compare Multiple Quotes
Get at least 3 quotes from different installers. Compare not just price, but component quality, warranties, and installer credentials.
Check CEC Accreditation
Ensure your installer is Clean Energy Council accredited. This is mandatory for accessing STCs and ensures quality standards.
Understand Total Cost
Quote should show price before and after STCs. Watch for hidden costs like meter upgrades, switchboard work, or scaffold fees.
Review Warranties Carefully
Product warranties (25yr panels, 10yr inverter) AND workmanship warranty (minimum 5 years) should be clearly documented.
Verify Grid Connection
Installer should handle network approval, meter upgrade, and retailer notification. Don't accept partial service.
Plan for Battery Future
Even if not installing battery now, choose a battery-ready hybrid inverter. Retrofitting later is more expensive.
