LONGi

Advanced solar technology delivers high performance, reliability, and
long-term value for Australian homes.
At AAA Electrical & Solar, we recommend LONGi Solar panels for homeowners looking for a reliable, high-performance system without the premium price tag.
Over the past few years, LONGi has evolved from a budget-friendly option into a true technology leader. Their latest panels now compete with top-tier brands in both efficiency and design, making them a smart and future-ready choice.
LONGi is one of the world’s largest and most financially stable solar manufacturers. By controlling the entire production process, from raw silicon through to the finished panel, they maintain a high level of quality and consistency.
We also value their strong Australian presence, with local support based in Sydney to assist with technical enquiries and warranty claims.

High Output Options Available
The Hi-MO 9 series delivers over 660W per panel, making it ideal for larger residential systems or commercial applications.
