Over 32% of residents in Queensland uses rooftop solar systems. The "sunshine" state has invested over $1 billion in the solar industry. The state contributes heftly to the renewable energy landscape of Australia, and as of 2019, the total power generation from the residential rooftop PV systems is more than the Gladstone Power station (1.68GW). With target of 3GW by 2020, Queensland has a lucrative feed-in tariff scheme. In Brisbane, the most populous QLD city, 6kW is the most popular among the residential customers, producing an average of 4 kWh per day.
As the innovation in the renewable energy industry continues, the power to price ratio for solar packages is at its lowest in Brisbane. This provides faster return-on-investment for residential consumers. The solar batteries are also projected to reach the consumer scale affordability in Australia by the end of 2021. These two factors provide highlights the obvious advantage - minimal grid dependency - of larger capacity rooftop systems. In short, they are future-ready, and leaves sufficient energy for storage and night-time use. A 6+ kW PV system with half-cell mono PERC panels and battery-ready (plug-n-play) inverter can provide the optimal payback in the long term.
Using the PERC based Q.Antum technology and advanced nano coating, Q-Cells are one of the most efficient panels in the industry. These solar cells can provide up to 19.5% under real-world conditions. Hanwah Q-Cells excels in long term reliability and durability through heavy investments in R&D centers, vertically integrated manufacturing and fully automated quality control system. They have a global sales and support network in 4 continents.
Since 2001, Canadian Solar have shipped over 33 GW of PV cells. They are used in some of the biggest commercial projects in North America and Australia (Normanton farm, Tacca Industries, IKEA Australia, to name a few.). The company has network spanning over 40 countries with more than 13,000 employees. They are the forerunners in the bifacial technology with the BIHIKU 430W bifacial panels.
With an annual capacity of 12GW, Jinko panels have 25+ linear performance warranty and 10 year product warranty. Their sales and support spans 38 countries. The Jinko panels are known for long-term weather resilience and industry-leading shade tolerance and low light performance. Jinko panels consistently rank within the top 3 of the Bloomberg Tier-1 panel rankings.
