What are the factors to consider when buying solar panels?

There are a number of factors that you should consider when selecting a solar panel. They are:


Any company can make promises about quality, materials, warranty and support but the key is selecting a product made by a company who can be trusted and who will be around in the long term to support you. Trustworthiness is hard to quantify but is usually best described through experience, reputation, commitment, transparency, integrity and size.

The quality of solar panels available on the market varies greatly. The type of aluminium used for the solar panel frame, the thickness and quality of the solder, the efficiency and quality of the solar cell, the water seal over time, the way the cells are encapsulated, the protection against micro cracking, the UV resistance of the backing sheet, the quality of the cables and plugs; together all of these factors determine the quality and longevity of the solar panel.

LG solar panels are made in South Korea, in a technologically advanced factory in Gumi, located near one of LG's state of the art LCD TV factories. Our manufacturing process is automated as can be seen in this video (LG's Automated Solar factory). Our panels are manufactured precisely to within a fraction of a millimetre of the specification. We only use high quality input materials and the quality control performed on our panels is as extensive as LG’s other world class electronic equipment such as its curved OLED TVs, washing machines, fridges, smart phones.

Trustworthiness also extends to your local supplier and installer of solar panels. Choosing a long established local company who has partnered with a diversified solar panel manufacturer is a great place to start. LG’s Authorized Dealer network offers you this combination.


Performance matters in two distinct ways.

Firstly, you need a solar panel that produces a good power level; this need not be the highest power level (unless you have limited space), but should certainly be towards the upper end of the typical power ratings available on the market, which will steadily increase over time as efficiencies increase.

Solar panel quality

LG’s Mono-X 2 60 cell panel has 285W and the current NeON 2 solar panel has 345W output, while many competitor panels only have a 250W output. Over the life of the home solar system, approximately 25 years, this higher output will save valuable roof space for future system expansion.

Secondly, the solid and ongoing panel performance of a solar panel should also be backed up by strong technical confidence. This can be observed through tight power tolerances, low and a clear description of how the products are tested, affected and rated against Potential Induced Degradation (PID) and Light Induced Degradation (LID).

A supplier who makes quality solar panels such as LG Electronics typically offers a strong warranty that provides peace of mind about ongoing performance and has the dependability if something goes wrong. LG offers a 25 year product warranty with full parts PLUS labour and shipment. Over 1,000,000 LG solar panels have been installed in Australia up to the end of 2018, and only two panels have been claimed on warranty.
