Panels & Systems


The next generation Mono X® Plus by LG combines everything a solar module needs: long service life and ease of installation as well as an elegant exterior, high efficiency and very strong warranty.


Great Visual Appearance
LG Mono X® Plus panels have been designed with appearance in mind. Their black cells and black frames give an aesthetically pleasing uniform black appearance. Your home deserves the LG Mono X® Plus.
12 Years Product Warranty (Parts & Labour)
The LG product warranty is 2 years longer than the industry standard 10 years and covers 12 years. The warranty includes replacement labour and transport.
More Power per Square Metre
LG Mono X® plus 300W panels are a similar physical size to many conventional 260W panels. This means with the LG Mono X® plus 300W you get 15.4% more electricity per square meter than a 260W panel. So you can install more kW of solar on your roof with the LG Mono X® plus.
Improved 25 Year Performance Warranty
The initial degradation of cells has been improved from -3% to -2%, in the 1st year and the annual rate of degradation has fallen from -0.7%/year to -0.55%/ year thereafter. This brings an 84.8% warranted output after 25 years, compared to 80.2% for many standard panels.
Proven Field Performance
LG has been involved in a number of comparison tests of the LG panels against many other brand panels. LG Mono X® range models are consistently among the best performing in these tests.
Reduced LID
The Mono X® Plus (LiLy technology) has reduced the initial degradation of solar cells by applying LG new LiLy (LID-improvement for Lifetime Yield) Technology, which controls the reaction of Boron and Oxygen, a key factor of LID (Light Induced Degradation).
Additional Certification
LG Mono X® Plus panels have received additional certification including for; Salt Mist Corrosion to maximum severity 6. Ammonia Resistance certification and PID Resistance Tests.
Extensive Testing Programme
LG solar panels are tested between 2 to 4 times the International Standards at our in-house testing laboratories, ensuring a very robust and longer lasting solar module.
Strict Quality Control Reliable for the Future
The quality control of LG world-class production processes is monitored and improved to Six Sigma quality control standards, which includes 500+ monitoring points to effectively maintain and improve our uncompromising standards.
Cyclone Wind Load Resistance
LG modules have a strong double walled frame and screwed corners. When it comes to wind forces (rear load) many competitor modules are certified to 2400 Pascals. LG modules are certified to more than double - 5400 Pascals, making them very sturdy and strong.
Multi Anti-reflective Coatings Increase Output
LG is using an anti-reflective coating on the panels glass as well as on the cell surface to ensure more light is absorbed in the panel and not reflected. More absorbed light means more electricity generation.
Positive Tolerance (0/+3%)
If you buy a 300 Watt panel then the flash test of this panel will show somewhere between 300W and 309W. Some competitor panels have -/+ tolerance, so you could get a flash test result below the rated Watt, meaning you pay for Watts you never get.
Solid High Temperature Performance
Solar panels slowly lose the ability to generate power as they get hotter. LG Mono X® Plus has a better temperature co-efficient than many standard poly panels, which means in high temperatures LG Mono X® Plus will deliver higher output.
Anti PID Technology for Yield Security
PID (Potential Induced Degradation) affects the long term ability of panels to produce high level electricity output. LG panels have anti PID technology and have been successfully tested by leading third party laboratories regarding PID resistance.
Excellent low light performance
Great performance under low light conditions due to the LG technology and our own cell manufacturing with low tolerances, ensuring highly consistent performing panels. At 200W/m2 LG panel efficiency drop is -2% while many standard panels reduce by -4%.
Fully Automated Production in South Korea
All LG solar panels are manufactured in a custom designed and fully automated production line by LG in Gumi, South Korea ensuring extremely low tolerances. This means great quality and build consistency between panels.

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.

LG solar panels are designed and tested to withstand hail stones

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.

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

Mono crystalline solar panels

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 18% 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 X2  and NeON 2 solar panels are of the Mono Crystalline type. The NeON 2 Black range is completely black and does not show the small white diamond fields.

Poly Crystaline modules

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 15-16%.

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. As a result, LG warranties against salt mist corrosion right down to the waterline for 12 years.

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.

LG's black frame solar panels offer a number of advantages over normal aluminium panels

solar panel - NeON

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 250W to 320W are used. LG's 285W, 300W and 320W panels have been optimised to give you the best value for money.

LG’s Mono X2 and NeON2 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:

  1. Testing
  2. Input materials
  3. Warranty condition
  4. Output and Efficiency
  5. Corrosion protection on frame
  6. Quality of Plugs and junction boxes
  7. The quality of wafer and solder
  8. UV resistance of the backing sheet
  9. Chemical stability of seals and sealants
  10. Weight

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 have been used in commercial projects in Australia and all over the world

LG Panels are perfectly suitable for solar projects. LG solar panels have been selected for many large commercial projects worldwide and also 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.

The AS/NZ 5033: 2014 is the latest Australian Standards for the installation of solar panels. The standard started in November 2014.

Some of the key aspects of the new standard are:

  1. All equipment and wiring shall be selected and installed in accordance with the provisions of AS/NZS 3000 and requirements of this standard (Clause 4.1). Please Note: Inverters must be installed in locations with safe access and adequate working space and be readily available(this does not apply to micro inverters).
  2. PV cabling must be identified with a permanent, indelible marking in English or coloured "SOLAR" labels attached at intervals of not more than 2 meters. When the PV cable is enclosed in conduit or other wiring enclosure a coloured "SOLAR" label must be attached at each end of the wiring enclosure and at each change of direction. (Clause 5.3.1).
  3. All outdoor equipment must be suitable for the environment and be at least IP 54 and UV resistant. (Clause
  4. All PV array switch-disconnectors must be readily accessible (Clause and are to be marked with an identification name or number according to the PV array wiring diagram and have clear indication of isolation position off and on e.g. O and I. (Clause 5.5.1).
  5. Earthing or bonding connections MUST BE arranged so that the removal of a single module earth connection will not affect the continuity of the earthing or bonding connections to any other module. (Clauses &

When special types of silicon are hit by sunlight they generate very small amounts of electricity. It’s know as the photoelectric generation effect and means that electrons are being ejected from the surface of the solar cell in response to the sun’s light. This describes the basic principle by which a photovoltaic (PV) solar cell transfers sunlight into usable electricity.

Sunlight has a range of solar spectrum and is made up of photons. When photos hit a solar cell they can be reflected or absorbed by the cell. The absorbed photons then generate the electricity as described above in the PV cell, which at that point acts as a semiconductor. When manufacturer’s increase the efficiency of solar cells they aim to have less sunlight reflected by the cell and more of the light absorbed. This increase of efficiency by the cell, then leads to a higher efficiency of the solar panel, as nowadays a majority of solar panels contain 60 solar cells and measure about 1 meter in width and about 1,6 meter in height. So if each of the 60 cells becomes slightly more efficient the whole panel will be more efficient.

By getting the energy from the sun the electron moves from its position in an atom of the solar cell and becomes part of the current flowing through the electric ribbons of the solar panel and start to generate DC electricity, which can get harvested through the junction box and leads at the end of a solar panel and be ready for use after having been converted from direct current power to alternate current power by a string inverter or micro inverter.

An electric solar power system is made up of three key components. They are:

  1. The solar power modules, also known as solar panels;
  2. The string inverter to transfer the DC electricity which normally comes out of solar panels into AC electricity, which can now be used by household appliances or manufacturing machinery. A new technology called micro inverters can also perform this function. Usually both micro inverters and string inverters offer monitoring options , usually on a screen on the inverter or via internet based monitoring options.
  3. The balance of system components such as mounting frames, safety switches, cabling etc.

Micro inverters as a concept have been part of the solar industry for a very long time and as a practical application since the mid 1980s. The key issue has been that the cost of manufacturing of downsized transformers and other components meant that micro inverters were not cost competitive against large conventional string inverters.

After 2011 a number of micro inverter brands using smaller components entered the Australian market and they enjoy a growing but still small market share. There are specific advantages of micro inverter solar systems for specific residential sites such as sites with partly overshadowing or where panels need to be mounted facing different directions, but overall micro inverter systems are still slightly more expensive than conventional string inverter systems.

Micro inverter

A micro-inverter converts power at the solar panel from DC electricity to 240v AC electricity and is attached to each panel in a solar system. As opposed to a conventional string inverter which is connected to a series or “string” of solar panels and converts the power from Direct Current (DC) in to Alternate Current (AC) electricity , for the solar system as a whole.

Micro-inverters are useful and recommended when there are shading issues across the solar panels or where you need panels to face different directions because of the roof design.

Micro-inverters allow each panel to operate on its own, so if a single panel or some panels are in shade it will not affect the output as the panel in sunlight will work to its full capacity.

Micro inverter connected to each panel

Some roofs are small and can fit only a few panels. Other roofs point in differing directions. To get efficient solar system output in such situations, a micro-inverter will be most suitable for the solar installation. With the use of micro-inverters you can have the panels oriented into two or more different directions, while string inverters require several panels to be facing in the same direction together.

Micro inverters also allow the performance of every panel to be monitored individually. In the case of a system fault or poor performing panel, micro inverters enable faster identification and repair.

Micro inverters may also reduce down time from breakdown. For example, if a string inverter stops working the whole solar system stops working and produces no power. If a micro inverter stops working, only the individual panel stops working and the rest of the panels in the system should still work and be unaffected.

Micro inverters also allow for expandability as you can add additional panels one at a time with another micro inverter. You can also use different brand or size panels in the system. With a string inverter it can be harder to expand a system, as it is dictated by the size of the inverter and additional panels need to be the same or almost identical in specifications to the existing panels.

Micro inverters will also allow for panels to be added at a later date as any number of panels can be added with a micro inverter. With a string inverter, only an identical panel can be added and only if the string inverter has the extra capacity/ room.

Micro inverter better than string inverter when there is shading

Micro inverters and string inverters both have their strengths and weaknesses. Micro inverters will be a better option in situations where the panels will be affected by shading or when panels need to be facing different directions on the roof.

String inverters, as a cheaper solution, will in most cases be the best option when there are no shading issues and several panels can be installed facing the same direction on the same roof surface

Strings of panels traditionally could be compromised in a shady environment as one panel shaded would reduce the output of all panels connected on the same string. High quality panels have bypass diode so an individual cell that is affected by a leaf, or bird dropping will not affect the overall performance of the panel or the other panels on the same string. An LG panel is also isolated into three sections so that shading on one section will not reduce the remaining sections of the panel. LG panels also produce more solar power per cell - up to 320W compared to 260W. With a higher amperage they can be configured in small strings, reducing the impact of partial shading.

The extra output claim depends on a number of factors, such as the system design, the actual solar module efficiency and site/roof specific issues. Many micro-inverter brands claim up to 25% increase in yield for their product when compared to string inverters, in situations where the panels experience heavy shading. The increase in yield would in most cases be between 5 to 10% in installations with no shading or compromising issues. For a detail analysis of what suits your specific installation situation please discuss the option of string versus micro inverter with your LG solar panel installer.

It is too early in the life of micro inverters to confidantly answer this question. Micro inverters are increasing in popularity, however it is most likely that both micro inverters and string inverters will both continue to be used as each has their own strengths.

Many costs are involved when running a household/ business. Most of the costs are essential and some of them can be reduced for lower cost of living expenditures. Electricity is a essential requirement in our households.

With the ongoing price rises of electricity it is becoming extremely costly to run households and businesses. One of the alternate ways to reduce electricity cost is to opt for Solar Electric Power.

Solar is a free energy from the Sun transferred into electricity. Solar electric power also helps to reduce green house gases. Solar is also cost effective as it is a one-time investment for a very long period, as quality solar panels can last for 25 years and longer.

So buying a good high quality panel and inverter will not only create a reliable PV system, but will also save money for years to come.

You can speak to your installer about your lifestyle and which time during the day or night you require more power to have the best use of the solar power system installed on your roof. You will also have an option to export the excess generated electricity back to the grid. You will get paid for the excess electricity you send back to the grid.

LG modules have Anti Reflective Glass Coating. Our production results to date show that standard test condition (STC) flash power gain due to Anti Reflective Coating on glass is on average 2.7%.

After more than three years of outdoor testing in various climates, the energy production gain from ARC glass modules is 3.5-5% depending on the type of installation and location. The higher energy gain as compared to STC flash gain is due to improved coating gain in diffuse and off-angled light due to the effect of the refractive index and the light scattering within the coating.

Normally full black panels loose performance on hot days – as obviously the black colour attracts more heat retention. Hot solar panels perform less efficient than cooler panels under the same sun irradiation levels.

The 300W LG NeON2 Black (see datasheet) has been designed for prestigious homes with great looks and it is also one of the best performing panels in Australia. The model has 12 multi-wire busbars – compared to the normal panel 3 or 4 busbars. As I will explain below – this means performance in high temperatures, even being full black are excellent and superior to some of the conventional panels. The NeOn2 Black also have N type, double sided wafers, not P type or polly wafers. N type perform better in heat and have a lower long term degradation factor.

In layman’s explanation… cells kind of become sticky for electrons when heat increases and therefore electron flow to the busbars, which are the superhighways that carry the electricity away - slows down and therefore output is negatively affected. As the NeON2 have 12 busbars (superhighways ) per cell the distance each electron has to travel to be “harvested” is less and therefore the effect of heat on the panels performance is significantly reduced.

Normally panels have to indicate on their datasheet their temperature co-efficency , which is the performance they experience in heat (see here the LG NeON 2 black number being -0.38%/C for Pmax) . The lower the number , the better the performance in heat. Normal polly panels usually have a temperature co-efficency of -0.43 and some better ones -0.42 or -0.41. -0.3 8 is the best temperature co-efficency of any panel on the Australian market and is only equalled by other top quality panels.

temp co-efficient for NeON2 blacks

In summary – yes conventional black panels can perform less in hot weather, but NeON 2 Black due to inbuilt new multi-wire busbar technology (we are 1st panel to have this on the market in Australia and NZ) does perform highly efficient even in very hot weather. Overall NeON 2 and NeON2 Black are some of the highest performing panels on the market.
