Rapid technological advancement coupled with renewable energy incentives and rebates is now giving more home owners increased access to powering their homes via solar energy and with electricity prices rapidly increasing, the best time to go solar is right now. A residential grid connect solar power system consists of just a few components:

  • Solar panels that capture and convert the sun’s rays into DC electricity.
  • A solar power inverter to change the DC electricity from the solar panels into more user friendly AC electricity.
  • Solar panel mounting hardware & framing, cabling, wiring & associated fittings.

Grid connect refers to a type of system that works in with your existing electricity service and is the most common type of system used in Australia today. Any surplus electricity created is simply fed back into the grid and you receive a credit on your production or in some cases, you may be paid a premium on that electricity you contribute! These incentives are called solar feed-in tariffs.

On cloudy days or at night, your house draws electricity from the main power supply as usual it’s all automatic and instantaneous, you’ll never even notice when the switch-overs occur. As there are no batteries in a grid connect system, the cost is greatly reduced and maintenance is minimal.

Home solar power, once terribly expensive, is now within the reach of many householders and it’s expected that within just a few years, residential solar power costs will reach price parity with coal fired power supplied by major utilities. Until that time, governments are offering very generous rebates and incentives to help reduce the cost and encourage the installation of systems; which will in turn help drive the costs down further through demand. However, incentives are constantly changing, usually becoming less generous over time.

Depending on your power consumption and system size, solar power can significantly reduce or even wipe out your power bills. Why not take advantage of renewable resources available to power your home, it might be far cheaper and easier to have installed than you think!.

Be sure to consult with an expert in the field before forking out your hard earned cash. A company experienced in residential solar power would be able to recommend the right equipment for your needs and also be familiar with renewable energy rebates and other incentives that can help offset the outlay.

What size solar power system do I need?, how many solar panels?, what size system will best suit your installation budget and your power consumption requirements?. Use the online solar calculator to find the best solar system size in kilowatts and how many solar panels you will need.

A good method used to calculate your solar system size is to take a look at your electricity bill, somewhere on your power bill there should be an indication of your average daily electricity usage. The average Australian home with 3 bedrooms uses around 10kWh to 18kWh. But don’t just look at one power bill, try to look at your bills across the entire year as power consumption can vary at different times of the year. For example in the summer months we may use air conditioning more, and in winter more heating and lighting. Your location can have a big effect on how much solar power can be generated.

In Australia the further south you go the less intense the sunlight is, a 1kW system on average will produce around 4kWh to 5kWh per day, so for an average energy efficient home at least a 3kW system will be enough.

During the day go outside and observe just how much direct sunlight your roof receives, and remember no sun means no solar power so if you live an a valley or are shaded by large trees your sunlight hours will be reduced having a big effect on just how much solar power your system can generate over all. If a solar power system can generate more power than you need during the day, a feed-in tariff can help pay for the power you use at night after the sun goes down, so even after dark you can still get free power from the sun.

You will also need to calculate how many solar panels are required for the amount of kilowatts you want to produce, and relate this to the size of your roof space keeping in mind that not all the roof space may be facing the right direction and angle for good solar power generation.

Solar Price Guide

Buying a solar power system for home or business may seem complicated to the average person as most of us are not solar power experts, however if you are reading this article then you have an internet connection, and that means with a little online research you can easily become a solar power expert.

Once you have a general idea of the size and type of solar power system you want to install you will need to start looking at and comparing system prices, remember when it comes to a solar system price buying cheap components at the start can be more expensive in the long run. Cheap solar panels and solar system components are just not worth it and will end up costing you more. Next is finding a reliable, reputable solar power installer who is Clean Energy Council accredited.

The solar industry has grown very fast in Australia and this has seen the rise and fall of many solar companies and small scale solar installation businesses. Once again use the internet to search around and find reviews, also ask other people who have solar about their experience with installers.

Your location can have a big effect on how much it will cost to install a system, In Darwin for example there are strict regulations for mounting anything on a rooftop due to the occurrence of extreme weather events such as cyclones. The average prices for grid connect solar systems in Australia Jan 2017:

  • 1.5kW – $2,700 to $4,400

Buy A Quality Solar System

When it comes to purchasing a solar power system the quality of the components will over time have a big effect on the economical benefit gained, for example a solar panel that has a slightly higher output and efficiency rating than another cheaper panel may seem like an expensive choice to begin with but over time the lack of output from the cheaper panel will end up costing you more. This is the false economy of installing a cheap system.

Buying top quality solar panels with a good high output is well worth it, and that goes for all other system components as well including inverters, in other words when it comes to solar spending more on a quality high performing installation will cost you less over time with years of trouble free service as it should be.

Some of the best rated and most reliable brands of solar panels are manufactured by DAQO, REC Solar, BenQ Solar, Panasonic, Phono Solar, Sharp, Yingli Solar, Suntech, HIT Technology & Sanyo. Some of the best rated and most reliable brands of inverters are manufactured by Power-One, SMA, Sharp, SolarEdge, Fronius, Sungrow & Enphase Energy.

Grid Connect Solar Power Systems

The majority of solar systems installed in Australian homes and businesses are the grid connect type and can range in size from 1kW or 2kW, 5kW and right up to 10kW and larger. These systems draw power from the solar panels during the day, when the sun goes down the system automatically switches over to draw electricity form the local power grid. There is also the option to sell excess power back to the grid.

A grid connect solar power system operates in the same way as any other solar system with solar panels and an inverter with the one exception of being connected to the local power grid. This gives the grid connect solar setup the ability to draw power from the grid as well as being able to feed power back in.

  • Sunlight shines on the solar panels and generates a DC electrical current.
  • The DC electrical current is channeled into a solar inverter and converted into 240V 50Hz AC electrical current.
  • The 240V AC electricity is used to power the electrical appliances throughout your home.
  • Any unused electricity flows back into the main power grid.

Whenever the sun is shining, the solar panels generate electricity. The grid connect solar inverter turns the DC electricity produced by the solar panels into 240V AC power, which is used by most standard home appliances and lighting.

When the grid connect system is making more electricity than is required, the extra power fed back into the local power grid. Most power companies monitor the electricity fed back into the grid by your system and will issue a credit to your power bill. Some companies will install a bi-directional meter that can run in reverse as your system feeds electricity back into the power grid.


If the solar panels are not making power, for example at night or when its too dark, the system will automatically switch over to the mains power grid to meet demand. The power company will charge the standard rate for any power used.

Because the components of a grid connect solar system have no moving parts, there is little or no maintenance aside from keeping the panels clean and trimming trees that may shade your panels. Government renewable energy rebates can help you to save even more and are constantly being updated and adjusted. Regardless of any rebates a solar power system will always save you money over any fossil fuel system.

Wind Power Vs Solar Power

Both wind and solar power generation systems can be connected to the grid, but which system is the best for residential areas?. What type of power system you choose mostly depends on where you live and the surrounding environmental conditions, for example the amount of wind or sunlight available in your location. In most situations in either urban areas or rural areas a solar power system is usually the best choice for reasons outlined below. Solar PV systems:

  • Have fewer mechanical components that require maintenance or could be subject to ware.
  • Is much more reliable than a wind power system.
  • Much less time spent monitoring the system.
  • Low maintenance costs and much longer operating life.
  • The output in more predictable, wind fluctuates and is unpredictable.
  • Is less obtrusive to those living near the system and zero DB or noise is generated.
  • Much easier and faster to install the system.
  • Less chance of being damaged by high wind events.
  • Much less space needed for installation, panels can be mounted on an existing rooftop.

The noise factor is a big one with some local councils banning the installation of wind turbines in urban or built up areas, another reason they can be unpopular is the visual effect. So as stated earlier it really depends on your location and power needs, out on a farm far from the neighbors in a high wind area a wind turbine may be just the thing for your home or business, or perhaps a combination of wind and solar will do the job.

Feed-in Tariffs

A feed-in tariff is the rate at which a power company will pay owners of grid connected solar power systems for the electricity they feed back into the grid from their solar power system. There is no national feed-in tariff program for Australia so schemes are run by the states and vary from state to state and between different electricity retailers. The net feed-in tariff system or export metering will pay the solar system owner for the excess electricity they produce. A gross feed in tariff will pay per kilowatt hour produced by a grid connected solar system.

Solar panel rebate & renewable energy subsidy information

It is possible to save thousands of dollars on the installation of a grid connected solar power system if you or your business is eligible for an Australian government solar rebates, subsidies and grants.

Before you can install a grid connect solar power system in your home or business, you need to confirm that your switchboard and power meter are up to date and compatible with the system. A switchboard is usually a weather proof cabinet or box where electrical fuses, circuit breakers and power meters are housed and are generally mounted on a wall on the outside of the premises.

To install grid connect 2 extra circuits need to be installed, unless there are already 2 spare unused spaces available you will need to get an electrician to make space for the solar system. If you have an older style switchboard with ceramic wire fuses it is strongly recommended that you upgrade your switchboard with modern safer circuit breakers and RCD’s for safety reasons.

In order to get the most out of your installed solar power system, you will be required to install a two-way or bi-directional power meter. This type of meter will measure not only the power you are drawing from the grid but also the amount of electricity generated by your solar system that is being fed back into the grid.

Solar Power For Business

Are you a small business owner or operator looking to reduce your greenhouse gas emissions and save money on your business running costs?. If so then one good method to achieve the above goals would be to install a grid connect solar power system, especially if you have machinery or plant systems that run mostly during the day like air conditioning or other large scale plant equipment.

Unfortunately many business owners don’t even consider installing a solar power system, as they consider it to be a weak or unreliable alternative to grid supplied power. This could not be further from the truth as today’s modern high tech integrated solar power systems are more than capable of delivering a good solid and stable supply of electricity to operate a business.

A grid connected solar power system for a business is no different from a system installed in a home in the way it operates, the principals and components such as solar panels, inverters etc are exactly the same, so if it works in the home it can work for your business with the right system capacity installed.

You may even find solar power to be more reliable in some cases where blackouts are common and disruptive to business, by installing solar you will become immune to these types of situations and able to supply a more reliable service to your customers.

As well as reducing your business carbon footprint and bringing operational costs down, there are other good reasons to install solar as the Australian government is offering incentives and rebates to encourage the uptake of solar power by businesses and commercial operators, some incentives include tax breaks and asset write offs for solar power systems, feed-in tariffs and Renewable Energy Certificates aka RECs.

Renewable Energy Certificates

Renewable energy certificates aka RECs are made available when you buy and install a certified solar power system or some other type of renewable energy systems like wind and solar hot water.

Renewable energy certificates can save you money as they can be sold and traded. The REC system is part of the governments attempt to assist the growth of renewable energy production in Australia and to help meet the 2020 greenhouse gas emission target. Australian renewable Energy Target:

  • The Australian government is aiming for a target of 20% renewable energy by the year 2020
  • The current requirement of the target is for 9500GWh of renewable energy output from power companies
  • Meeting the 2020 target will require 45000 GWh of clean energy generation
  • 1MWh of power is equivalent to 1 REC, therefore 45,000,000 RECs are needed to reach the 2020 target
  • In order to achieve their target, the power companies need to submit RECs to a holding account at the end of every year at an amount representative to 20% of their market share
  • When an energy company fails to deposit enough RECs in its account, it will be fined at a rate that is higher than the value of the REC itself


1 REC has the same value as 1 megawatt hour of electricity generated. A renewable energy certificate can be swapped for money and the value of the certificates changes depending on the market. In other words a REC could be seen as a type of renewable energy currency. If you own a certified solar system you can claim RECs yourself by filling out and submitting the appropriate paperwork, however this can be a little confusing for some and not to mention time consuming so there are companies the specialize in managing this for you.

Solar Airconditioning

It makes no difference where you live in Australia from Tasmania to Queensland or the dry arid west or outback summer time can be very hot and unbearable, the luxury of air conditioning can be expensive to run 24/7 during the summer months and can add a big chunk to your monthly power bill. But it need not be so. The reason summer is hot is because the sun is much more intense and the daylight hours are longer, and this is the perfect formula for generating solar power with PV panels.

So lets put the two together, a need for air conditioning in summer plus summer being the best time to generate solar power. Its a no brainer!, install a solar power system to generate electricity to power the air conditioning unit and get your home or business cooled this summer for free, as long as the sun shines on your solar panels you can let that AC unit run with no worries about power costs. Now why didn’t you think of that sooner?.

Solar Panels & Solar Modules

When most people think about solar power the first image that comes to mind is one of a solar panel mounted on a rooftop. There is much more to a solar power system than the solar panels, however it is the panels that are usually the most visible part of the system due to the need for them to be mounted in a position with the best exposure to the sun.

A solar panel is made up of a number of smaller solar photovoltaic modules connected together, these modules are made from mono-crystalline or polycrystalline silicon and are very thin and fragile, thus the need to mount them on a rigid structure or frame that forms the solar panel we see on most rooftops.

Solar modules produce direct current DC using something known as the photovoltaic effect which was first used to help power spacecraft back in the late 50’s. Since that time the technology has evolved and in recent times we have seen exponential growth in both the domestic industry and the solar technology sector.

Solar modules are rated depending on their DC output to surface area ratio using a standard test, a module with a higher output and efficiency rating will need less surface area than that of lower rated module. So buying better quality solar panels may mean less roof space is needed to produce electricity. Some of the highest rated solar panels and solar modules available in Australia are manufactured by REC Solar, Daqo, Sharp Solar and Phono Solar.

Photovoltaics PV

Photovoltaics or PV for short refers to a method for creating DC electrical current using semiconductors and the photovoltaic effect. Photovoltaic power generation uses solar panels which are made up of a series of smaller solar cells usually made from exotic minerals such as mono-crystalline silicon or polycrystalline silicon.

In recent times the rapid expansion in use and demand for solar panels has seen many advances in this high tech photovoltaic industry. Advances in PV technology and in the manufacturing process have driven the price of solar power down all around the world making it very competitive with the more traditional types of power generation like coal, oil and gas.

Government incentives such as feed-in tariffs and solar rebates have assisted the rise of the photovoltaic industry. Photovoltaics generates DC electricity by using solar cells to convert sunlight into electrons using the photovoltaic effect. The photovoltaic effect is where photons excite electrons increasing the energy of the electron which becomes a charge carrier for electrical current and was first observed by Alexandre-Edmond Becquerel in 1839.

Yingli Solar Panels

Yingli Solar Panda 60 Yingli Solar is one of the world’s largest solar panel manufacturers. Yingli Solar leads the way in solar PV development and technology and holds the statistic of being represented in 10% of the world solar market share.

REC Solar Panels

REC Singapore inetgrated solar facility

REC solar panels are some of the most environmentally friendly panels available on the Australian solar market. They can also boast one of the fastest payback times of around one year. A recent test carried out on all the top brand solar panels found the REC Peak Energy Series solar modules to be the top performing modules outputting around 6% more power than other polycrystalline, mono crystalline panels in the test.

Due to their superior design REC solar panels output more power per square meter partly due to the use of three bus bars and better conductivity between the cell and metal fingers, increasing electrical current flow. All of the above factors make the REC panels a good investment especially where roof space is limited.

DAQO Solar Panels

DAQO polysilicon nuggets

The BenQ group of companies can be found all over the world and have a very large number of employees well over one hundred thousand. Manufacturing a large range of solar panels for many different and unique applications, the BenQ range have an excellent reputation for reliability and efficiency.

Panasonic Solar Panels

Panasonic solar panel

Another great quality brand of solar panel is Panasonic. Panasonic have a very strict testing regime for every solar product that leaves their factory insuring the best quality control. Panasonic solar modules have a 10 year warranty for workmanship and construction as well as a 25 year performance warranty. Panasonic’s signature solar panel the HIT panel has a very good surface area to output ratio making it a very good choice when there is little roof space available.

Solar Panel Mounting Systems

solar panel mounting

The method and equipment used to mount solar panels to a roof or on the ground is just as important as any other component in the system. Solar panel mounting frames, brackets & fixtures should be highly resistant to corrosion and manufactured to Australian standards AS/NZS1170.2:2011.

Imagine paying good money for your solar panels only to have them blow away in an extreme weather event such as a cyclone or storm.

The majority of grid connect solar systems are of the roof mounted type. In most parts of Australia, the roof mounted solar modules should be north facing to be able to take full advantage of the suns rays.

Clean Energy Council accredited grid connect solar installers should always attempt to install the solar panels at an angle that ensures that the glass face of the panels is at the right angle to the sun for most of the day. For an example, in Sydney the best angle would be about 30 to 40 degrees to the horizontal. Most standard Australian roofs have an angle of elevation around ~22 degrees, which is ok. This gives a close approximation to the position in which a solar system achieves maximum output. If the system is to be fixed to a flat roof an elevated framework is required to achieve the correct mounting angle approximately 30 degrees from the horizontal.

Solar Inverters


Solar panels only produce DC electricity, so for practical purposes this DC power needs to be converted into AC before it reaches your power-points and that’s the job of the solar inverter.

At the heart of every solar power system is the solar inverter, so what is the function of the solar inverter?.

Basically there are two forms of electrical current , direct current DC and alternating current AC, batteries like your car battery or the batteries in flashlights and toys only output DC current and the devices that use these batteries are deigned to operate with DC electricity.

The power that comes from your household wall mounted power-points is AC which is used to power the majority of electrical appliances in your home or business.

Solar panels only produce DC electricity, so for practical purposes this DC power needs to be converted into AC before it reaches your power-points and that’s the job of the solar inverter.

There are many different brands of inverters on the Australian market and the quality can vary a great deal, an inverter also needs to be matched in capacity to the expected load it will be required to handle 2kw, 3kw, 5kw and so on. A good quality unit should not build up too much heat, have quiet operation and give you years of trouble free power.

Some of the top solar inverter brands available in Australia are manufactured by SMA, Power-One, Sungrow & Sharp Solar.

Sungrow PV Grid Connect Inverters

BenQ Green Triplex Solar panel

Micro Inverters & AC Solar Panels.

Micro Inverter

A micro inverter is a small device that attaches to the end of each individual solar panel and converts the DC power produced by the panels into AC electricity.

Relatively new on the solar system market is the micro inverter, and as the name suggests these inverters are smaller than the conventional type and are usually attached to the end of each individual solar panel eliminating the need for one larger central unit.

The micro inverter system has its advantages and disadvantages.

Solar panels produced DC electricity the same type of electricity that comes from most standard batteries, in order for this type of electricity to be useful for powering home appliances and connecting to the grid it is converted into alternating current (AC) via a device called an inverter.

In a grid connect solar power system the solar panels are connected in a series or string to produce high voltage DC, this is good for reducing power loss however there are some problems associated with this method and that is where the Micro Inverter comes in.

A micro inverter is just as the name suggest, a small inverter designed to attach to individual solar panels instead of the entire string or array.

A standard “Series String” array The majority of solar panels installed in Australia are configured using this method, with a individual inverter.

The good things about Micro Inverters

There are problems that arise when connecting solar panels together using traditional methods such as in a series or string, a micro inverter can help to deal with these problems which include:

  • High voltage DC generates heat when conducted which means a risk of fire if not installed to standard or if the cabling becomes damaged or worn, a micro inverter reduces this risk as the electricity is converted to safer cooler AC right at the source.
  • The protective equipment like switches and fuses needed for DC are more expensive than AC, by having only AC in the system maintenance cost will be much lower.
  • If one solar panel in a series or string is in the shade this can effect the performance of all the other panels and thus the entire system, with the micro inverter system this is not so as each panel operates independently of its neighbor.
  • Not all solar panel are the same even if they are the same brand and rated size, this is know as “mismatch” and can cause problems for string connected panels. Micro inverters operate independently of each other so they can adjust to any differences between panels.
  • If a string system inverter is faulty or fails the entire system will shut down, if a single micro inverter is faulty the system can still continue to output power be it at a reduced rate, and if the system is fitted with isolators for each panel or inverter it is possible to replace the damaged unit without shutting down the entire system.
  • In a string setup all the solar panels need to be mounted in close proximity and facing the same way so that they can operate as one connected unit, with a micro inverter this in not necessary.

The bad things about Micro Inverters

Micro Inverters are relatively new and there are some minor disadvantages such as:

  • Being mounted on the roof with the solar panels if there is a fault that need to be repaired that means the technician must climb onto the roof adding to the expense of repair and if its raining repair could be impossible.
  • Effects of weathering, delicate electronic devices sitting on a roof in the weather wind and rain can become damaged no matter how good the plastic or metal housing is it will eventually break down.
  • Efficiency, Micro Inverters are not as efficient as DC string connected panels, they are getting better all the time and in the future may overtake DC

Like any complex electrical system things can go wrong, components can fail causing a total system breakdown if they are not installed to the proper Australian standards.

A solar power system should only ever be installed by a qualified electrician who is accredited with the Australian Clean Energy Council, this will insure that your system is installed to the proper Australia safety standards and is industry compliant.

The Solar PV accreditation is a qualification that demonstrates competence in design and installation of solar power systems. To be eligible for government incentives such as RECs, solar credits and feed-in tariffs the installer you choose must be accredited by the Australian Clean Energy Council.

A Clean Energy Council accredited solar designer & installer:

  • has completed necessary solar specific training courses
  • signs on to a Code of Conduct
  • is bound by the accreditation Terms and Conditions
  • Follows the CEC guidelines, Australian Standards and all other relevant regulations

The aims of the accreditation scheme are:

  • To improve the safety, performance and reliability of solar photovoltaic power systems installed in the field
  • To encourage industry Best Practice for all design and installation work involving solar photovoltaic power systems (see Accreditation Standards and Accreditation Rules)
  • To provide a network of competent solar photovoltaic power systems designers and installers
  • To increase the uptake of solar photovoltaic power systems to generate electricity, by giving customers increased confidence in the design and installation work.
