Solar Grid Connect System

This system uses the energy from the sun to generate electricity for your household or small business. The sun's rays when absorbed by silicon cells in a photovoltaic panel releases electrons. The stronger the rays the more electrons flow. These panels produce a small voltage of direct current. A number of panels are connected together and wired to an inverter. This inverter converts the direct current into alternating current suitable for normal household use. After the initial cost of the supply, installation and connection of a solar grid connected system there are no ongoing costs required to generate electricity. That is, free electric power. Most photovoltaic panels have a 25 years warranty, and the inverters have at least 10 years.

Before grid connect inverters became available the solar panels charged a bank of 12 or 24 volt batteries which were connected to an inverter to produce 240 volts. This was called a stand alone or off grid system. The development of the Grid Connect Inverter did away with the high cost of batteries but is only suitable where there is a electricity supply grid to connect to.

Greening Your Home

Solar electricity generators use Photovoltaic Cells which produces a small direct voltage (DC), about 0.6 volts, when exposed to sun light. A number of these cells are connected in series to now produce approximately 36volts. A typical solar panel is arranged with 3 strings of 20 cells in series to increase the voltage output.

Solar Panel - Cells

Solar panels are available with average output power in the range from 160 watts to 235 watts and higher.

Depending on the total output of the system a number of these panels are connected in series and wired to the inverter. i.e.. eight 235 watts panels would produce approximately 1880 watts (1.88 kw). There are losses in the wiring and in the inverter so expect less final output than the rated output of the panels.

Eight Solar Panels in Series

The grid connect inverter converts the varying DC voltage from the panels to 240 volts alternating voltage (AC) suitable to use in the house. This inverter monitors the grid supply voltage and frequency and constantly adjusts its output to suite before allowing any current to flow to the grid. If the electricity supply on the grid is disrupted (power outage) the inverter will shut down to prevent injury to any electricity supply workers. This will mean if there is a blackout while the sun is shining there will be no output from the inverter. ie. No power to the premises.

Solar Cells

The commercially available solar panels used in stand alone and grid connect systems currently are all based on silicon. Depending on the how the cells are structure, the cells are classed as polycrystalline/multi-crystalline, monocrystalline or amorphous.

Polycrystalline or Multicrystalline:

Cells are cut from an ingot of melted and recrystallised silicon. In the manufacturing process, molten silicon is cast into ingots of polycrystalline silicon, these ingots are then cut into very thin wafers and assembled into complete cells. Simpler manufacturing process leads to lower prices but they tend to be slightly less efficient. They have a speckled crystal reflective appearance “metal flake effect”.

Monocrystalline Silicon Cells:

The cells are cut from a single cylindrical crystal of silicon. This is the most efficient of the photovoltaic (PV) technologies being high efficient, around 15%. As the manufacturing process is complicated the result is slightly higher costs than other types. The cells are recognized by an even external coloring.

Amorphous Silicon:

Amorphous silicon cells are composed of a thin layer of silicon deposited on a base material such as metal or glass and are not a crystal structure. These Amorphous solar panels are much cheaper, but their energy efficiency is also much less.

Effect of Shade on Solar Panels

Shade on just 6 cells of a 60 cell panel can shut down the panel completely.

See shading effects

Inverters

An inverter converts the PV panels Direct Current (DC) to an Alternating Current (AC) that is required for power generation.

Connections:

A number of PV panels are connected in series to increase the DC voltage that meets the inverters input voltage range eg 150-400V. This arrangement is referred to as a String. More than one string may be connected to some inverters to increase the power output, but not to exceed the inverters maximum design specifications.

Maximum Power Point Tracking (MPPT):

The PV panels produce the maximum power at a certain voltage and current value for the available sunlight. The maximum possible power output is maintained by the inverter adjusting its load on the PV panels. This function is called Maximum Power Point Tracking (MPPT). Some inverters have more than one MPPT input, allowing different size/type of PV strings to be connected.

Function:

The inverter monitors the grid supply voltage, frequency, and phase and may also check the line resistance. The inverter output is adjusted to suite the grid supply before switching power from the PV panels. Synchronisation is maintained while connected to the grid. To provide current flow to the grid the inverter output voltage is raised above the grid voltage. Grid-tie inverters will shut down in the event of a supply power outage to prevent possible harm to line workers.

Types:

At least three different technologies are used in inverters.

  • Conventional low-frequency transformers
  • High-frequency transformers
  • Transformerless - lighter weight and higher efficiencies

As transformerless inverters lack galvanic isolation between the DC and AC circuits, the PV panels are required to be earthed.

 

Selecting the size of a Solar Grid connect system

The power used in a typical Australian house could be 20,000 watts (20kw) averaged each day.

This equates to 833 watts per hour.

When using Solar Panels to generate the power, we need to determine the average number of sunlight hours.

Depending on where the location in Australia that the installation is, it may have on average eight hours of sunshine which will give four (4) hours of suitable sunlight if using fixed stationary PV panels.

For the Average annual & monthly sunshine duration visit:- Bureau of Meteorology

From the above site the average annual and monthly sunshine hours in Australia can be obtained. For non-tracking PV arrays only about half of these hours are suitable to produce energy for the PV cells. If your location has 8 hours of sunshine then the solar system will be generating electricity for approximately 4 hours. 

So to produce 20kw in four hours we need to generate 5k watts each hour.

Therefore we need 25 solar panels(if 200 watts each) and a 5kw inverter.

If your house is using twenty kilowatts (20kw) a day, then you will be generating all the power required for the average year.

From 1 July 2010, Independent Pricing and Regulatory Tribunal has approved an average increase of 10 per cent for Energy Australia customers (around $2.42 per week), 7 per cent for Integral Energy customers (around $1.63 per week) and 13 per cent for Country Energy customers (around $3.52 per week).

These percentage price increases will not change because they did not include any costs for the CPRS. Price increases approved by Independent Pricing and Regulatory Tribunal from 1 July 2011, and 1 July 2012, will now be less as a result of the CPRS not being introduced. Prices will now rise on average in 2011 by 11 per cent, and 8 per cent in 2012.

The already agreed future increase of electrical charges should be included in any calculations when selecting the size of the solar grid connect system. Ie add more at the initial installation or design a system that additional panels can be added later when required.

Small-scale Technology Certificates (STC)

was formally known as Renewable Energy Certificates (RECs)

 

     What is a STC?

A Small-scale Technology Certificates (STC) is an electronic, tradeable commodity equal to 1 Megawatt hour of renewable energy generation. A STC is similar to a share certificate as it represents a unit of value and may be traded for financial return. In the REC Registry, each STC is identified by a unique four-part code which includes:

  • the Registered Person Number of the original creator of the certificate
  • the accreditation (Power Source) of the power station, small generation unit or solar water heater for which the STC was created
  • the year in which the STC was created
  • a serial number.

A Small-scale Technology Certificates can be traded for cash and the value of these certificates fluctuates according to market conditions. Basically, a STC is a form of renewable energy currency and through agents you can sell your STCs.

The amount of STCs each system can produce is different - it depends on the size of the system and the location. Australia has been divided into four zones for both solar PV and solar water heater installations, which represent the differing number of sunlight hours across Australia.

Each installation will fall into one of these zones. Each zone has been allocated a value which is used to work out the Solar Credits value payable by the Federal Government.

The Australian Government has recently announced on the 5th May 2011, changes to the Solar Credits multiplier which will apply from 1 July 2011. Solar Credits program will now be phased-out over the next two years, with the incentive program to effectively end on July 1st, 2013.

To work out the number of STC for a system you need the following:-

  • The kilowatts capacity of the system.
  • The Zone value:- Based on the installation location in Australia.
  • Zone1 = 1.622
  • Zone2 = 1.536
  • Zone3 = 1.382
  • Zone4 = 1.185
  • The Deemed years value:- Based on who installed the system.
  • If installed by a Credited installer use the value of 15. All installations after 20th August 2010 require a Credited installer.
  • If NOT installed by a Credited installer use the value of 5.
  • The Date installed value - Installed early the rate value is higher.
  • If installed 9th June 2009 - 30th June 2011 use the value of 5
  • If installed 1st July 2011 - 30th June 2012 use the value of 3
  • If installed 1st July 2012 - 30th June 2013 use the value of 2
  • If installed 1st July 2013 - 30th June 2014 use the value of 1

Accredited Installation

STCs can be created on a “deemed basis” for the installation (before 20 Aug. 2010) of PV systems. Owners of these systems eligible for STCs can choose to create STCs in either 1, 5 or 15 year deeming periods.

Under the Act and Regulations CEC accreditation is now required for all Solar (photovoltaic) units installed on or after 20th August 2010. Therefore a Deemed multiplier of 15 is applied in calculating the number of STC for a system.

CEC accredited installers are required to:

  • Ensure that the installation has all applicable local and state/territory Government approval requirements
  • Ensure that the SGU and its installation, including wiring, meets Australian and International Standards, and that key components are listed on the Clean Energy Council’s list of approved products.
  • Ensure that the mounting and orientation of the SGU are in line with the Clean Energy Council accreditation requirements.

Documents required for compliance before STCs can be assigned to the agent

If you are installing a solar photovoltaic panel on or after 20 August 2010 or installing a small-scale wind or hydro unit on or after 20 December 2010 your agent/installer/retailer

  • May ask you to sign a statement that all required local and state/territory Government requirements have been met.
  • Is required to provide you with a copy of any documentation required, by the laws of the jurisdiction in which the unit was installed, certifying that the electrical installation of the unit complies with laws relating to safety and technical standards. This could be in the form of a Certificate of Compliance, Installation Report and Electrician’s Licence. For further information regarding relevant installation certification please contact your relevant state authority.

Owners of systems can claim STCs themselves by completing the appropriate application forms. However, this can be confusing and time consuming, so most people choose assigning their right to claim STCs to an agent. 

example for a 2115 watt system installed by a Clean Energy Council accredited installer in a Zone 3 location.

STC     =          Zone Rating      x          Power Output   x          Deemed Years

43.844 =          1.382               x          2.115               x          15  
rounded down = 43.      

STCs can only be claimed within 12 months of the system being installed.

Deemed years of 15 can only be claimed if the system was installed by a Clean Energy Council (CEC) accredited installer (see this list).

The number of STCs must be rounded down to the nearest whole number.

Currently the STC price varies daily alike the share market. However from 1 January 2011 the government is fixing the price of a REC at $40 (under the Small Scale Renewable Energy Scheme).

see the Office of the Renewable Energy Regulator - STC Clearing House http://www.orer.gov.au/clearinghouse/index.html

Solar credit multiplier

The Solar Credit is calculated by the Kilowatt capacity of the system multiplied by the Zone Rating and multiplied by an installation date multiplier value and by the number of Deemed Years.

To encourage the early installation of Small Generation Units (ie Solar system) the Date of Installation multiplier is set at 5 for the first three two years then dropping down to 2 over the next three two years.

The Solar Credits scheme gives you a bonus by allowing you to get 5 times the number of STCs for the first 1.5kW installed (most household systems will be between 1.5kW and 3.0kW). if installed before 1st July 2011.

The Multiplier is only applied to the first 1.5 kilowatts in a system.

The Australian Government announced on the 1st December 2010 that changes to the Solar Credits multiplier will apply from 1 July 2011. Under the amendments, support for home solar power installations will begin to be phased out a year earlier than previously planned.

The Australian Government announced on the 5th May 2011 that changes to the Solar Credits multiplier will apply from 1 July 2011. Under the amendments, support for home solar power installations will begin to be phased out a year earlier than previously planned

STC Formula

Calculating STCs for small solar (photovoltaic) systems

RET process for Owners of Small Generation Units (SGUs)

STCs for system up to 1.5kw.

 	STC = (Zone Rating) x (Multiplier) x (Power Output)  x (Deemed Years)

 

STCs for system over 1.5kw.

	STC	= (Zone Rating) x (Multiplier) x (1.5) x (Deemed Years)
					+
         	 (Zone Rating) x (Power Output - 1.5) x	(Deemed years)

 

Ie for a 2.115kw system installed at post code 2536 before 1/7/2011 will produce:-

Number of STC       = (1.382) x (5) x (1.5) x (15) + (1.382) x (2.115-1.5) x (15)

                              = (155.48) +  (12.749)

                              = 168.229

                              = 168 (rounded down)

The Solar Credit should therefore =: 168 x $40.00(value of a STC)= $6720.00

Solar Bonus Scheme for NSW

The NSW Government's Solar Bonus Scheme (the Scheme) commenced on 1 January 2010. The Scheme provides support to people who produce renewable energy through eligible roof-top solar photovoltaic (PV) systems and wind turbines connected to the grid. The Scheme's objectives are to:

 

  • Encourage and support those who want to generate renewable energy as a response to climate change.
  • Develop jobs in the renewable energy sector by assisting renewable energy generation to compete with non-renewable energy generation.
  • Increase public exposure to renewable energy technology to encourage the whole community to respond to climate change.

The Industry & Investment NSW website provides general information on the Solar Bonus Scheme to assist individuals and businesses interested in participating in the Scheme. Industry & Investment NSW cannot provide advice on the individual circumstances of interested participants. Each customer has the responsibility for ensuring that their renewable energy generator installation meets all requirements of the Solar Bonus Scheme including complying with the metering and connection requirements of their distribution network.

 

Key features of the Scheme

 

  • It commenced on 1 January 2010 and will operate for 7 years, ending 31 December 2016.
  • It credits eligible customers who joined the scheme before 28th October 2010 with a gross meter with a 'gross' feed-in tariff rate of 60 cents per kilowatt hour for all the electricity that their eligible solar photovoltaic (PV) system or wind turbine generates.
  • Certain customers who meet all requirements for eligibility under the NSW Solar Bonus Scheme (other than having gross meters installed) and who prefer to install or remain on net metering may choose to receive net credits for their generation.
  • Small electricity customers (those with an annual electricity consumption of up to 160 megawatt hours) are eligible to participate in the Scheme.
  • Only customers with solar photovoltaic (PV) panels and wind turbines (up to 10 kilowatts in capacity) that connect to the electricity network through an inverter (up to 10 kilowatts in capacity) are eligible to participate in the Scheme.
  • Solar PV systems installed and connected after 1 January 2010 must be installed by a person, who at the time of the installation had a Grid-connect Design & Install accreditation from the Clean Energy Council to be eligible for the Solar Bonus Scheme.
  • Each eligible small electricity customer is entitled to receive the Solar Bonus Scheme credit for one eligible renewable energy generator (solar photovoltaic system or wind turbine) only.
  • The tariff rate of 60 cents per kilowatt hour will be fixed for the life of the Scheme, meaning it will not vary with the time of the day or during the life of the Scheme.
  • The Scheme will be reviewed in 2012 by the Minister for Energy, or when the installed capacity of renewable energy generators participating in the Scheme reaches 50 megawatts, whichever occurs first.
  • NSW Solar Bonus Scheme Statutory Review October 2010 - For all eligible systems purchased or leased after 27 October 2010, a new "gross" tariff rate of 20 cents per kilowatt hour will apply. The new program will be subject to a review on 1 July 2012 and at the end of the program (31 December 2016).

About CEC

The Clean Energy Council is the peak body representing Australia’s clean energy sector. It is an industry association made up of more than 350 member companies operating in the fields of renewable energy and energy efficiency.

The CEC’s members are involved in the development or deployment of clean energy technologies such as wind, hydro, wave and tidal, solar, solar hot water, bioenergy, geothermal and cogeneration.

The CEC is an incorporated not-for-profit association which is based in Melbourne and operates nationally. It is funded principally by membership fees, with additional income generated by events and activities such as industry accreditation programs.

Solar PV accreditation?

Solar PV accreditation is a qualification that demonstrates competence in design and / or installation of stand-alone (SPS) and/or grid-connected (GC) solar photovoltaic power systems.

The aims of the Accreditation scheme are -

  • to increase the uptake of solar photovoltaic power systems for the provision of energy services, by giving customers increased confidence in the design and installation work;
  • 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.
  • to provide a network of competent solar photovoltaic power systems designers and installers.

The Clean Energy Council (CEC) takes advice from its Standards, Training and Accreditation (STA) committee. This committee is formed from industry members, across the nation, with wide experience with renewable energy, plus a representative from government and a Clean Energy Council Director.

Individuals who have completed (or received Recognition of Prior Learning (RPL) or Advanced Learning) the required Accreditation training can become accredited.
