Here’s how to tell if a solar dealer is focussing on quality versus cheap products. If they are focussed on quality, they will focus on the following brands:

Solar Panels

LG panels – https://www.lgenergy.com.au/

LG’s solar products are manufactured in South Korea. LG has over 60 years of experience in global electronics manufacturing and product development. LG has 30 years of research and development in the solar industry, cementing the company as a leading innovator and manufacturer of solar panels globally and in Australia and New Zealand.

LG’s new 25 year solar product warranty is 15 years longer than the industry standard. Customers can benefit from longer product warranties, higher panel efficiency and less long-term panel degradation.

It is essential you invest in quality solar products. Cheap solar manufacturers are often unreliable and unsafe, and disband before consumers can claim warranties. LG provides you with the confidence of a reliable service.

As of February 2020 less than 100 panels have been replaced due to manufacturer related issues – from over 1.2 million LG panels installed across Australia and New Zealand since 2010.

Inverters
