LG solar modules are designed with durable glass to be light in weight (17.3 kg) while also being able to withstand heavy loads and external pressure up
to 5400 Pa.
High Testing Standards
After a rigorous process, LG’s product durability testing laboratory has earned certification from both TÜV Rheinland and UL (Underwriters Laboratories), a first in the solar industry.
LG Sign-Off on Every Cell
LG is proud to sign-off on every single manufactured solar cell with our LG brand. The LG logo represents LG's commitment to cutting edge technology and durability standards which have guided LG for over 50 years.
The Mono X™ warranties include a 10 year product warranty and a linear 25 year output warranty. The linear output warranty guarantees a minimum power output of 80.2% after 25 years. Because it’s backed by LG these warranties give you peace of mind.
Positive Power Tolerance
LG provides rigorous quality testing to all solar modules to ensure the rated power output. Our Mono X™ modules have a positive nominal tolerance starting at 0% and going as high as +3%.
Reliable For The Future
LG’s world-class integrated production processes and quality controls create a solar product that is reliable and durable. For example every single LG module undergoes two Electroluminescence inspections to detect any micro cracks unseen by the naked eye.
Solar panels are designed to withstand varying weather conditions for many years. Hail, frost and very hot weather are part of the Australian landscape. LG panels are designed and tested to withstand hail stones up to 28mm, 90 degree hot temperatures and up to -40 degree frost.
Nevertheless should extreme hail stones cause any damage to your solar system most of the home insurance companies cover hail damage as the solar system installed on the roof is part of your building. However different insurance companies can have different rules. We suggest you should find out if your solar power system is covered in your particular circumstances.
Solar panels are made from Silicon. Silicon (Si) is an abundant non-metallic chemical element which makes up almost 30% of the earth's crust and is the 7th most common element in the Universe. To make the solar cells which make up a crystalline solar panel, crystalline silicon is sliced into thin wafers - a few millimeters thin. These are then cut to shape and polished. LG makes the solar cells for our panels in Gumi Korea.
Give me some key solar facts:
A solar panel, also called a solar module is made up of either 72 or 60 solar cells. They are electrically interconnected in series and parallel and sandwiched between glass and plastics, then framed. A typical 60 mono-crystalline cell solar panel produces around 250 to 300Watt Watts at an open Voltage of around 38 Volts DC.
A solar array is a group of solar panels connected together.
A solar system is a solar array connected together with electronic equipment such as a DC to AC power inverter and other hardware like circuit breakers to complete a fully functional solar power system.
There are three main types of solar panels available in the marketplace:
1. Mono Crystalline
These solar panels are a proven technology that has been in use for over 40 plus years. There are out there Mono Crystalline panels installed in 1980, which still work today. They are one of the most efficient solar panel technologies and are more efficient than the other two technologies represented here. Mono Crystalline panels are commonly used where installation space is limited, or where there are high costs associated with installing panels, as Mono Crystalline technology for larger solar power systems can potentially use less panels than the other two technologies. The average efficiency for standard Mono Crystalline panels is 15% plus.
When it comes to appearance Mono Crystalline panels are usually black with white diamonds. Mono- Crystalline solar panels have a very slow degradation, meaning they lose relatively less efficiency every year. LG’s Mono-X solar panels are of the Mono Crystalline type. The Mono-X Black range is completely black and does not show the small white diamond fields.
2. Poly Crystalline – also known as Multi Crystalline
These panels are similar to Mono Crystalline panels, but the silicon used is Multi-Crystalline which is easier to make. It is usually slightly less efficient than Mono Crystalline in performance. The Poly Crystalline panels are usually blue in colour. Slightly more panels are required for larger systems than Mono Crystalline systems. In very hot environments Poly Crystalline can hold their own against Mono Crystalline, due to the usually slightly better temperature co-efficiency. The average efficiency for standard Poly Crystalline solar panels is around 14.5% plus.
3. Thin Film
These panels are typically nearly double the size than the other panel varieties. The reason is, that they are markedly less efficient. Research is continuing to improve the performance of Thin Film panels and to refine the manufacturing process. They respond well to slightly diffused light and their efficiency does not drop significantly on hot days. There are currently few thin film panels on the market in Australia for residential systems.
Black framed panels offer a number of advantages over normal aluminum panels. Aesthetically they merge with your roof and do not look ugly and the coating on the frames give you additional protections against the natural elements. LG panels have 2.2ml of extra coating of paint and protective layers over the anodized aluminum frame. On average strong weathering reduces the top coat by 0.1 mm per annum. This means your LG solar panel frame will have 22 years protection against the elements, before the anodized aluminum is exposed to weathering. Many conventional solar panels have only got a 1 mm clear protective coating, meaning after 10 years the panel frame is exposed to the elements.
Solar panels are used for a variety of applications from a small garden solar light to space stations and satellites. The use of the solar product determines the size of the panel. In residential solar systems the large panels with average outputs from 190W to 300W are used. LG's 260W, 290W and 300W panels have been optimised to give you the best value for money.
LG’s Mono-X and Neon solar panels are designed to withstand long exposure to the elements such as heavy rain, hail and wind. They have been extensively tested in their research laboratory for impact and wind resistance. In our testing laboratory, even loads of 800kg are placed on the panels as part of the testing regime.
All solar products, whether panels or inverters, have to comply with Australian Standards to be eligible to for the Clean Energy Council’s list of approved products. If a product is not on this list and/or is installed by someone who is not registered/certified with the Clean Energy Council, the system will not be allowed to be connected to the grid and will not be eligible for any rebates. Being on the CEC list however is not always a guarantee for being a top quality product.

Cheap solar panels and quality solar panels differ in:
Buyers should insist that the installation company undertakes a physical site inspection. There are many variables that need to be considered and most of these are hard to spot from a satellite view of your house or a few photos. An installer's willingness to visit you gives some indication that there is a service to support your purchase. We strongly advise you to buy your solar system from a local company, not an internet based solar sales agent.
If the company cannot find the time to see you when they want to sell you, what chance have you got for them to come when the system stops working?
In the past, when solar sales over the internet were skyrocketing, consumers purchased a solar power system without site inspection only to have their installer say they need special roof brackets or a total switchboard upgrade before the solar can be installed, adding unexpected costs for the consumer.
Our LG Authorised Dealers will come for a site inspection to check the roof position, discuss your electricity usage pattern, discuss monitor options and possibly conduct a shade analysis, to ensure you are putting your panels in the prime position.
Before making your decision, check who you should contact if you have questions after your installation or something isn't working properly. Also make sure you to ask for a written warranty from the installation company for the cabling and installation work itself, not just the panels, inverter and mounting frame.
Ask your installer if there is an in-house qualified electrician who can come in the future should you have a problem. May be you can request for their contact details. The cheaper installation companies rely on subcontractors, which can make it difficult to provide consistent installation quality and good post-installation service.
Check the company's background and what solar-related experience the staff and management have. Do they have CEC-accredited designers and installers who can check your design? Ask for references from other customers.
Solar is an industry where size does matter. We usually recommend a system size that can cover approximately 50% of your electricity needs. Contact your LG Authorised solar dealer to work out what home solar power system size will best match your usage.
Ultimately you get what you pay for. Not all panels and inverters are equal and the quality of installation components and installers can vary substantially.
LG Panels are perfectly suitable for solar projects. LG solar panels have been selected for a number of large commercial projects worldwide and in Australia. Please have a look at our commercial solar gallery section and the commercial solar reference document for some samples.
Since Q2 2013, LG is using high transmission tempered glass with Anti Reflective Coating. This type of glass increases the light which is capable of traversing the glass surface and actually hits/reaches the solar cell.
LG modules have been manufactured with great care and have undergone final functionality testing. Our input materials and manufacturing processes undergo the strictest quality control and our product testing laboratory has been certified by both TUV Rheinland of Germany and Underwriters Laboratories, USA, a first in the solar industry.
1. 10 Year Product Warranty for Module(s)
Subject to the terms in this document, LG will for a period of ten (10) years from date of purchase authorise a free of charge repair or replacement (at LG’s discretion) of the module, if in LG’s opinion, it needs repair or replacement because of a manufacturing or materials defect appearing within, and notified to LG in accordance with this warranty. This warranty is only applicable to modules under normal applications, installations, use and service conditions.
2. 25 Years Limited Warranty for Power Output
LG guarantees that for a period of one (1) year from date of purchase the actual power output* of the module will be no less than 97% of the labelled power output. From the second year, the actual power output will decline annually by no more than 0.7% for a period of remaining 24 years, so that by the end of the 25th year, an actual output of at least 80.2% of the
nameplate power out specified on the module will be achieved.
If the module does not reach the warranted power output levels set out above when measured by LG or by an independent measuring institute agreed to prior to testing by LG under standard test conditions (IEC 61215) taking into account a ±3% tolerance range for the measuring equipment, LG will, at its sole and absolute discretion, either (i) repair the Module(s); (ii) supplement such deficiency in power by either: (a) providing additional module(s) to the Customer, or (b) replacing the Module(s); or (iii) Refund the difference between the guaranteed minimal power output at the time and actual power output (measured under LG’s STC) multiplied by the market price of the Module(s) or a comparable model at the time of the Customer’s claim. *The power output values shall be those measured under LG’s standard test conditions as follows: (a) light spectrum of AM 1.5; (b) an irradiation of 1000 W per m2 and; (c) a cell temperature of 25 degrees centigrade at right angle irradiation.
3. Warranty Transfer
The Warranties provided in this Manufacturer’s Warranty are transferable when the Module remains installed in its original location. This means, when a customer sells their home with LG Modules installed, the new owners of the property will continue to enjoy the LG manufacturer’s warranty protection. The warranty period runs from the original date of purchase.
This LG Manufacturer’s Warranty only applies to service within Australia and New Zealand to units purchased within Australia and New Zealand. No LG employee or authorised distributor has the authority to vary the terms of this warranty.
5. How this Limited Warranty applies
Modules presented for repair or replacement may be replaced by new or refurbished modules of the same type rather than being repaired. Refurbished parts may be used to repair the modules. The replaced Module(s) or parts will become LG property should LG wishes to retain these modules. In the event the Module(s) is no longer available, LG reserves the right, at its sole option, to deliver new or remanufactured module(s) that may differ in size, colour, shape, model number, and/or power level. Any repaired or replaced modules will be technically compatible with the existing solar system.
6. Place of Service
The Limited 10 year Manufacturer’s Warranty covers the transportation cost for reshipment of any repaired or replaced Module(s) to the Customer site. Repairs or replacements of modules within metropolitan areas and areas immediately surrounding metropolitan areas will be conducted at the customer’s premises free of charge. If customer’s live outside of the metropolitan areas under the terms of this warranty, LG or its Authorised Service Centre may charge a travel fee to attend the premises. Service calls will be made during normal business hours, Monday to Friday. LG’s Authorised Service Centre may charge a fee for service calls made outside these hours. If a Module(s) returned to LG is found not to be defective or this Limited Warranty has expired, the Customer is responsible to pay for return shipping cost.
