Tier 1 vs Tier 2 Solar Panels: What It Means
Tier 1 panels are manufactured by financially stable companies with strong manufacturing practices. However, being Tier 1 doesn’t always mean they are the most efficient or best performing – it’s a bankability rating, not a quality guarantee.
Solar Panel Degradation Rates
All panels degrade over time, typically losing 0.3% – 0.5 % efficiency per year. Panels like SunPower and REC offer lower degradation rates, ensuring better long-term performance.
Solar Panel Warranty Types Explained
- Product Warranty: Covers manufacturing defects.
- Performance Warranty: Ensures output won’t drop below a certain level over time.
Always review the fine print – longer doesn’t always mean better if conditions are too restrictive.
Common Myths About Solar Panels
- “Expensive = Best” – Not always. Some mid-priced panels outperform premium ones.
- “All warranties are the same” – They’re not. Product and performance warranties differ.
- “All panels perform the same in every climate.” – Australian conditions vary; choose accordingly.
Government Rebates & Incentives (2025)
- STCs (Small-Scale Technology Certificates) reduce upfront costs.
- State rebates are available in NSW, VIC, SA, and QLD.
