Go Sunny Solar's decision to transition to LONGi solar panels, following the exit of Q-Cell solar panels from the Australian market, is strategically grounded in LONGi's cutting-edge advancements and record-setting achievements in solar technology.

Technological Innovation and Efficiency

LONGi has recently set a new efficiency record for its crystalline silicon heterojunction back-contact (HBC) solar cells, reaching an efficiency of 27.09%. This achievement was certified by the Institute for Solar Energy Research Hamelin (ISFH), a reputable German lab. This level of efficiency surpasses many competitors in the market and demonstrates LONGi's leading position in solar technology innovation.


Efficiency in solar panels is paramount as it directly translates to the amount of electricity generated from sunlight. Higher efficiency means that fewer panels are required to produce the same amount of power, which can lead to cost savings on materials, installation, and land use.

Advanced HBC Technology

 The crystalline silicon heterojunction back-contact (HBC) technology utilized by LONGi represents a significant advancement in solar cell design. This technology combines the benefits of hetero junction, where a layer of amorphous silicon is placed atop crystalline silicon for enhanced charge collection and transport, with back-contact cells, which feature all electrical contacts on the rear side of the cell. This design maximizes the cell's surface area for sunlight absorption, eliminating the shading that front-side contacts can cause, thereby boosting efficiency.


Cost-Effective Manufacturing

 LONGi's achievement is not just in efficiency but also in manufacturing advancements. By adopting an all-laser patterning process, LONGi has managed to reduce the high patterning costs typically associated with back-contact cells. Traditional manufacturing of HBC cells relied on an expensive photolithographic patterning process. LONGi's innovative approach not only reduces production costs but also lowers the consumption of indium, a rare element, by 80% compared to traditional bifacial heterojunction cells. This reduction in material cost is a crucial factor in making solar power more affordable and accessible.

Sustainability and Material Efficiency

 The significant reduction in the use of indium, a scarce and expensive element, reflects LONGi's commitment to sustainability and environmental responsibility. By minimizing the reliance on rare materials, LONGi is contributing to the development of more sustainable solar technologies that can be produced at scale, reducing the overall environmental impact of solar panel production.



 The decision by Go Sunny Solar to adopt LONGi solar panels is a forward-looking move that aligns with the company's commitment to providing high-quality, efficient, and cost-effective solar solutions. LONGi's record-setting efficiency, combined with innovative HBC technology and cost-effective manufacturing processes, positions these panels as a superior choice for meeting Australia's renewable energy needs. This transition not only reflects Go Sunny Solar's dedication to embracing the latest advancements in solar technology but also ensures that its customers benefit from the most efficient, sustainable, and cost-effective solar solutions available in the market today.
