Frequently Asked Solar & Battery Questions
Everything you need to know about rooftop solar panel efficiency, inverter technology, battery backup, and Australian government STC rebate incentives.
How much can I realistically save on my electricity bill with solar?
Savings depend on your system size, orientation, and energy consumption patterns. A typical Australian household installing a 6.6kW solar system can save between $1,200 and $2,200 annually, offsetting 60% to 90% of daytime grid electricity.
What is the Australian Federal STC Solar Rebate?
Small-scale Technology Certificates (STCs) are federal government incentives that act as an upfront point-of-sale discount on the purchase price of eligible solar systems. Supreme Solar Power automatically calculates and deducts this rebate upfront from your quotation.
What is the difference between string inverters and hybrid inverters?
A string inverter converts direct current (DC) from your solar panels into alternating current (AC) for household use. A hybrid inverter manages both solar panels and battery storage simultaneously, allowing seamless addition of a battery without extra hardware.
How long does a typical solar installation take?
Most residential rooftop installations (6.6kW to 13.2kW) are completed in a single day by our Clean Energy Council accredited electricians. Commercial installations (39kW to 99kW) typically require 3 to 7 business days depending on roof structure.
What warranties protect my solar investment?
All Supreme Solar Power systems come with three layers of protection: a 25-to-30 year linear performance warranty on solar panels, a 10-year manufacturer warranty on inverters, and our exclusive 10-year comprehensive workmanship guarantee.
Do you install on tile, tin, and flat concrete roofs?
Yes. Our CEC accredited installers utilize engineered Clenergy and Schletter mounting hardware tailored to corrugated tin (Colorbond), concrete tile, terracotta tile, and Klip-lok commercial metal profiles.
