Before Installing Solar: 10 Things Perth Homeowners Should Know
Before Installing Solar: 10 Things Perth Homeowners Should Know
Investing in solar is a big decision. Before signing any contract, make sure you understand these key factors that affect your system’s performance, savings, and long-term value.
1. Check Your Roof Condition
Solar panels last 25+ years, so your roof should be in good condition. If your roof needs replacing in the next 5-10 years, consider doing it before installing solar to avoid the cost of panel removal and reinstallation.
2. Roof Orientation Matters
North-facing roofs in Perth generate the most solar energy. West-facing roofs produce more afternoon energy (great if you are home in the evenings). East-facing produces more morning energy. Even south-facing roofs can work with the right system design.
3. Understand Your Energy Usage
Review your last 12 months of electricity bills. Your daily kWh usage determines the ideal system size. A typical Perth household uses 15-25kWh per day, which is well suited to a 6.6kW system.
4. Verify CEC Accreditation
Only use a Clean Energy Council accredited installer. This ensures quality workmanship, eligibility for the STC rebate, and compliance with Australian standards. Talk Energy holds full CEC accreditation and EC15564 electrical contractor licence.
5. Compare Quality, Not Just Price
The cheapest quote often uses budget components that underperform. Compare panel brands, inverter quality, warranty coverage, and the installer’s track record. A premium system costs slightly more upfront but delivers significantly better long-term value.
6-10: Additional Considerations
Also consider: single-phase vs three-phase power limits, whether you want battery storage now or later, shading from trees or buildings, your feed-in tariff rate, and whether your switchboard needs upgrading. Talk Energy covers all of these during your free consultation.
Frequently Asked Questions
What if my roof needs repairs before solar?
If your roof is older than 15 years or shows signs of wear, it is best to complete repairs or a re-roof before installing solar panels. Removing and reinstalling panels later for roof work can cost $1,000-$2,000 and risks voiding panel warranties. Talk Energy can assess your roof condition during a free site inspection and advise whether repairs are needed first.
How do I choose the right solar system size?
The right system size depends on your daily electricity usage, roof space, and budget. Most Perth households using 15-25kWh per day are well suited to a 6.6kW system, while larger homes or those with pools and air conditioning may benefit from a 10kW or 13kW system. Talk Energy analyses your past 12 months of energy bills to recommend the ideal size for your specific needs.
Is CEC accreditation important for solar installers?
Yes, CEC (Clean Energy Council) accreditation is essential. Only CEC-accredited installers can create the Small-scale Technology Certificates that provide the federal rebate worth $2,500-$3,500. CEC accreditation also ensures the installer follows Australian standards for safe, quality workmanship. Talk Energy is fully CEC-accredited and holds an EC15564 electrical contractor licence, giving you confidence in both the installation quality and your eligibility for government incentives.
