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:

Trustworthiness

Any solar panel company can make a promise about quality, materials, warranty and support but the key is selecting a product made by a company whose promises 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 in 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, all these factors together determine the quality and longevity of the solar panel.

LG panels are made in South Korea, in the Gumi  technologically advanced factory, located near one of LG's state of the art LCD TV factories. Our manufacturing process is automated as our video example (LG's Automated Solar factory) shows . Our panels are manufactured to within a fraction of a millimetre to the same specification. We only use high quality input materials. 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

Performance matters in two distinct ways.

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

Solar panel quality

LG’s current Mono-X 2 60 cell panel has 285W and the NeON 2 has 320W output, while many other panels only 250W output. Over the life of the home solar system, assumed to be 25 years, this higher output per panel 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 which can be demonstrated through tight power tolerances, a low temperature co-efficient 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 12 year product warranty with full parts PLUS labour and shipment. In over 280,000 LG panels installed in Australia up to May 2016, only two panels have been claimed on warranty.
