LG Solar Panels

LG has been manufacturing electrical goods since the 1950’s and have the most stringent quality control procedures when manufacturing their solar cells and solar modules.

The LG laboratory is certified as a Photovoltaic testing laboratory by TUV and UL – the only solar manufacturer who has been given this certification allowing them to test other manufacturer’s solar power products to ensure that they are to standard. This is proof that the LG manufacturing and testing facilities are one of the world’s best.

LG’s panels are vertically manufactured–meaning that LG undertakes all aspects of manufacturing, from silicon production to solar module assembly, and is serious about being in the solar game for the long-term: parent company LG Electronics has acquired more solar-related patents (172) between 2009 and 2011 than any other solar panel manufacturer. This sort of dedicated research and development is another indicator of the likelihood of the company’s being around in 25 years’ time to service warranties.

LG signs off on every cell.  Each solar cell in each solar module is individually checked for integrity and stamped with the LG logo, so customers know they can rely on their modules to perform over the course of their expected working lives

LG Neon Solar Panels

The new, premium NeON 2 panels are one of the most efficient solar panels on today’s market, optimising roof space and producing more electricity than standard mono-crystalline modules.

Choosing the premium and efficient NeON 2 panels by LG, can over the years save you money on your electricity bills and installation cost, when compared with a standard solar panel.

The NeON not only generates solid electricity output, but with their black anodised frame also win in stylish appearance. If you are seeking a premium solar product the LG NeON 2 panels are for you.

The NEW GEN 5 LG NeON 2 panels are available in 335w and 320w BLACK (Totally black)!  And the best thing about them is they are they same size as a standard 250w solar panel!   They are ideal if you a have a shortage of roof space and trying to extract maximum output.

LG solar panels come with an industry leading 25 year product warranty and 25 year performance warranty held here in Australia by LG Electronics.


REC Peak Energy Solar Panels

REC (Renewable Energy Corp) was established in 1996 and its Headquarters are based in Oslo, Norway. November 2010, REC opened its new state of the art full automated, integrated wafer, cell and module plant in Tuas, Singapore.

Currently REC has the 8th largest market share out of all panel manufacturers.

REC, being a fully integrated panel manufacturer means they make every component for their solar panels from the polysilicon, wafers, cells to the modules themselves, none of the whole process is outsourced.

Ongoing field testing of 46 solar module brands during all seasons and light conditions by Photon Magazine during 2011 determined REC solar panels to be the best performing panel; generating 6 percent more electricity on average than the other polycrystalline, monocrystalline and thin film panels tested.

The REC Peak Energy solar panel series were also nominated for 2010’s coveted Intersolar Photovoltaic’s Award and won the Solar Industry Award for Module Innovation, presented by Solar PV Management Magazine, in August 2010.

REC solar panels have an exceptional temperature co-effcient of 0.40% which means they will outperform most other panels in hot conditions. They also have 4 bypass diodes instead of the standard 3 diodes to combat shade and low light.

REC solar modules, if installed by Keen 2B Green include an industry leading 12 year product warranty, instead of the normal 10 year industry standard warranty.  They also come with a 25 year linear performance warranty.

Fronius International GmbH is an Austrian company, based in Pettenbach, Upper Austria.

It is an international company with a 65 year history in the manufacture of welding equipment and nearly two decades of experience with solar inverters and other devices for monitoring and controlling energy, including battery chargers. Fronius inverters are suitable for a wide range of applications, including residential solar and commercial solar projects.

Fronius inverters are manufactured in Austria, and include the impressive Galvo and Symo 3 phase range.

The Galvo is not just an inverter it is also an energy management system.With power categories ranging from 1.5 to 3.1kW, the Fronius Galvo Inverter is perfect for households – and is especially suitable for self-consumption systems.

The Symo is a compact three-phase inverter designed for maximum flexibility. Boasting power categories ranging from 3.0 to 20.0 kW, the transformerless Fronius Symo is the three-phase inverter for systems of every size. The high system voltage, wide input voltage range and two MPP trackers ensure maximum flexibility in system design.

The Fronius Galvo and Symo Inverters all incorporate the following impressive features: WLAN System Monitoring, monitor your system from anywhere in the world in real time using smartphones, tablets and PC’s all at no extra cost. Energy Management Functionality, the integrated energy management relay allows the self-consumption component to be maximised by directing power to run a specific appliance such as a pool pump when there is sufficient solar energy to do so. They also include plug-in card technology for retrofitting additional functions.

Fronius has an Australia office and service centre in Tullamarine, Victoria. Fronius inverter come with a standard 5 year product warranty, plus 5 years parts warranty for a total warranty of 10 years.

SolarEdge is a provider of power optimizer, solar inverter and monitoring solutions for photovoltaic arrays. These products aim to increase energy output through module-level MPPT.  Founded in 2006, SolarEdge established the DC power optimizer segment and is leading it with over 70% market share.

A  SolarEdge Power Optimizer is fitted under each solar panel which optimizes energy output by performing Maximum Power Point Tracking (MPPT) individually for each panel and maintains a fixed DC string voltage. Power optimizers also collect performance measurements and telemetries of each panel, and transmit the data over existing power lines.

The SolarEdge solar inverter is responsible for DC to AC inversion while MPPT and voltage management are handled by power optimizers separately for each module. Fixed string voltage ensures operation at the highest efficiency at all times (98% maximum efficiency), independent of string length and temperature.

A web-based and iPhone applications provide module-level, string-level and system-wide PV Monitoring.  The software provides alerts on a wide range of issues affecting energy generation that might otherwise go undetected.  Data and alerts are presented on a virtual site map and can be pinpointed to specific location to reduce maintenance time and costs.

The SolarEdge system is excellent for installing solar panels on roofs with shade and / or installing solar panels on multiple roof facings, and can outperform other solar installations by up to 25%, for a faster return on investment.  Recently in NREL designed independent testing, Solar Edge systems outperformed string and micro inverters.

SolarEdge has an office here in Australia with tech support.  The SolarEdge inverter comes with 12 year warranty and the optimizers have 25 years warranty.
