Second solar system from Zip Solar – This is my second solar system installed from Zip Solar. Did a professional job (nowadays it's very hard to get those kind of professionalism). Done a perfect job by the installer, and I am very happy with the system. I gave them more than 10 quotations that I believe, and they gave me the best offer with the premium products. I prefer them in the future solar installation.

While a 6.6kW system is standard, a 13.2kW solar system is the ideal "future-proof" choice for modern Australian homes with high energy usage. If you have ducted air conditioning, a swimming pool, or an Electric Vehicle (EV), a 13kW system provides the necessary buffer to cover heavy loads during the day while still charging a battery for nighttime use.
On average, a 13.2kW solar system generates approximately 45kWh to 55kWh of clean energy per day. This high output is capable of reducing electricity bills by up to 90% for high-consumption households. In sunnier regions like Perth or Brisbane, daily yields can consistently reach the higher end of this range, ensuring maximum grid independence.
In 2026, the average payback period for a 13.2kW solar system in Australia is between 3 to 5 years. This rapid ROI is driven by the efficiency of Tier 1 panels and the high price of grid electricity. As a NETCC Approved Seller, Zip Solar ensures these systems are designed to deliver over 20 years of nearly free energy after the initial investment is recovered.
A 13.2kW system typically utilizes 30 x 475W high-efficiency panels, requiring approximately 55m² to 65m² of usable roof space. Zip Solar’s SAA-certified installers conduct detailed roof assessments to optimize panel placement across available north, east, and west-facing sections to capture the most sunlight throughout the day.
