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 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 via lamination processes, 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. Not all panels are the same. Usually you get what you pay for.

LG 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 per this video https://www.youtube.com/watch?v=v0_UUPYqmQE

LG 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

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. LG’s current NeON 2 panel has 350W and the NeON R has 370 and soon 375W. Many other panels only have a 320 to 330W output. Over the life of the home solar system, being with a quality LG panel 25 years plus, this higher output will save valuable roof space for future system expansion, when batteries and electric car charging might require bigger systems.

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 temperature co-efficient (meaning excellent performance in hot weather) , 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, like LG Electronics, typically offers a strong warranty that provides peace of mind about ongoing performance and company dependability. LG offers a 25 year Product Warranty with full parts plus labour and shipment. In over 1,2 million LG panels installed in Australia and NZ by late 2019, the panel warranty claim rate is very low. LG still has compatible panel models in its Eastern Creek warehouse as warranty stock, for any local model sold since 2010.
