LONGi
Solar Panels

Advanced solar technology delivers high performance, reliability, and
long-term value for Australian homes.

Overview

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.

About LONGi Solar

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.

Technology & Innovation

LONGi has moved away from traditional panel designs and now focuses on its advanced HPBC (Hybrid Passivated Back Contact) technology.

What this means for you:

Sleek, Wire-Free Design

The latest Hi-MO X6 and Hi-MO 9 panels feature a clean, modern look with no visible grid lines, allowing them to absorb more sunlight while improving the overall appearance of your system.

High Efficiency Performance

With efficiency levels reaching up to 24.8%, these panels sit comfortably among the top-performing options available today.

Better Low-Light Output

The improved cell design allows for stronger performance in cloudy or hazy conditions, helping maximise your energy production throughout the day.

High Output Options Available

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

Sustainability & Manufacturing

LONGi is also committed to sustainability, with a goal of using 100% renewable energy in its manufacturing by 2028. They have already made significant progress toward this target.

Because they manufacture everything in-house, we can rely on consistent quality and tighter control compared to brands that outsource production.
