When only the best will do

LONGi, has been producing monocrystalline solar cells for themselves and other panel manufacturers for over 18 years.

The number one panel manufacturer globally and one of the top five solar panel producers for efficiency, LONGi holds many patents on monocrystalline solar cell technology and has been leading the way from the beginning. In addition, many other brands use LONGi solar cells and PERC technology in their panels, making the LONGi itself even stronger financially. LONGi is the only Chinese manufacturer to ever rank in the elite category, with Australia’s Solar Reviews scoring 40/50. LG’s solar panels scored 43/50 as a reference.

Quality you can trust

Industry-leading technology and quality

LONGi solar panels have long been at the forefront of technology in the solar industry because they developed much of the technology we use today. Knowing their equipment can handle the heat and UV in the Australian environment gives us additional peace of mind when installing LONGi’s solar panels on our client’s homes and commercial premises.

We know they will last 25 years, unlike cheap panels that regularly fail to make it to 18 months to 5 years despite offering a 25-year performance warranty. Cheap cells will crystalise and crack, have hot spots, and risk fire. That is why we only use brands we can trust, like LONGi, because your family and business deserve the safety and peace of mind that comes from using a quality product. Not to mention the increased reliability and return on your investment over 25 years.
