Grid Connect Session 1 • What is grid-connect? • Is there money to made? • Why do this skill-set? • Risk management? J.P. Teasel version 27/11/2011

Grid Connect • Session 1 What is grid connect? Source http://www.google.com.au/imgres?imgurl J.P. Teasel version 27/11/2011
Grid Connect • Session 1 What part of the Grid connected PV System is considered to be prescribed electrical installation work? Those parts of the generation system operating at or above 120 Volt dc, cables installed between panels and between the array and inverter and the ac cables installed between the inverter and the switchboard to which the generation system is connected along with all the required isolation and protection devices, are prescribed electrical installation work. For the purpose of section 45 of the Electricity Safety Act 1998, prescribed electrical Installation work means work on all or any part of the following electrical installations if they ordinarily operate at low voltage or a voltage exceeding low voltage. (f) Wiring systems, switchgear, control gear and accessories installed to provide control and protection of generation systems (excluding stand alone power systems with a power rating that is less than 500 volt-amperes) J.P. Teasel version 27/11/2011
Grid Connect • Session 1 The following activities are considered to be prescribed electrical installation work; Adding panels to an existing solar grid connected PV where the open circuit voltage (Voc Array) exceeds Extra Low Voltage. Upgrading the inverter due to increase in generation capacity The replacement of one component part of prescribed electrical installation work ‘like for like‗ such as an inverter or isolator can be entered on a non-prescribed certificate without the mandatory inspection. Reference – Electricity Safety (Installations) Regulations 2009 – Regulation 238(3) J.P. Teasel version 27/11/2011
Grid Connect • Session 1 IMPORTANT: The NSW Government announced on May 13, 2011 that the NSW Solar Bonus Scheme is closed to new applications retrospectively from midnight 28 April 2011 and also plans to cut the feed in tariff rate for those who signed up to the Scheme under the original 60c rate. There will be no change for people participating in the program under the subsequent 20c per kilowatt hour arrangement http://www.energymatters.com.au/government-rebates/solar-bonus-scheme.php J.P. Teasel version 27/11/2011
Grid Connect • Session 1 How does the NSW Solar Bonus Scheme work? Under the Solar Bonus Scheme, all households and eligible small business and community groups installing solar power systems will be paid 20 cents per kilowatt hour for all electricity produced! In most other states, a premium is only paid on surplus electricity generated. The NSW Solar Bonus scheme will allow for a system size of up to 10kW - far larger than most households need to supply all their electricity needs http://www.energymatters.com.au/government-rebates/solar-bonus-scheme.php J.P. Teasel version 27/11/2011
Grid Connect • Session 1 Can an electrician still make a business out of grid connect? The following slides may offer some incite J.P. Teasel version 27/11/2011
Grid Connect • Session 1 Data Source: PV-GC spreadsheet based on the CEC GC Design Guidelines The rated output is that achieved in perfect laboratory conditions. The CEC design summary software takes these deratings into account when predicting average for any given system. A typical Australian house consumes around 18 kilowatt hours (kWh) per day so a 1-2kW system displaces an average of 25-40% of your average electricity bill. Solar panels produce more energy in summer than they do in winter. J.P. Teasel version 27/11/2011
Grid Connect • Session 1 What government schemes are in place to lower the cost of purchasing a solar PV system? There are currently four types of financial assistance offered for solar PV systems in Australia: • Small-scale Technology Certificates (STCs) • Solar Credits • Rebates (applications for rebates must have been received by June 2009) • Feed-in tariffs J.P. Teasel version 27/11/2011
Grid Connect • Session 1 STC prices Small-scale Technology Certificates (STCs) The financial benefit supplied to you by an agent, or the total price given to you by a certificate broker/trader, can vary from day to day. This is because STCs are traded in the STC market (like the stock market) and so prices vary depending on supply and demand. The only time the STC price is fixed is if it is to be traded through the ORER-managed STC Clearing House. Prices of STCs are fixed at $40 (excluding GST), regardless of what the STC market is doing. In the past decade, when the certificates were traded via a market, the spot price of a certificate has varied between AUD$15 and AUD$60. This information is based on data provided to ORER by certificate brokers. Brokers monitor the price of certificates and their information can be found on the web. http://www.orer.gov.au/sgu/solarcredits.html J.P. Teasel version 27/11/2011
Grid Connect • Session 1 Consumer guide to buying household solar panels (photovoltaic panels) Solar Credits The Solar Credits scheme6 for solar PV systems is based on the REC scheme, but multiplies by five the number of STCs able to be created for your solar PV system. These extra credits only apply to the first 1.5kW of system capacity. So if your system is larger than 1.5kW, you will receive Solar Credits plus an additional STC for every one megawatt hour of electricity able to be generated by your solar PV system. The table below shows the level of financial support available from Solar Credits on solar PV systems in the major capital cities of Australia: J.P. Teasel version 27/11/2011
The current SRES Legislation multiplier is as follows. Grid Connect • Session 1 http://www.orer.gov.au/sgu/solarcredits.html J.P. Teasel version 27/11/2011
Grid Connect • Session 1 Feed-in tariffs Several states have introduced, or are in the process of introducing, feed-in tariffs. A feed-in tariff pays you for electricity generated by your solar PV system. Under a net feed-in tariff, a premium is paid for any solar energy that goes back into the grid from your house. So if you have surplus energy generated by your solar panels, you get paid for it; and if you use all of the energy you generate it will be offset against your normal electricity bill. Under a gross feed-in tariff you get paid for every unit of electricity generated by your solar panels, regardless of whether it goes into the grid or is used by your household. J.P. Teasel version 27/11/2011
Grid Connect • Session 1 Do you need accreditation with the CEC? SOURCE J.P. Teasel version 27/11/2011
Grid Connect • Session 1 Solar PV accreditation is a qualification that demonstrates competence in design and/or installation of solar power systems. To be eligible to give your solar customer government incentives such as RECs, solar credits and feed-in tariffs the installer must be accredited by the Clean Energy Council J.P.

Grid Connect • Session 1 Do want a 1.5kW system?/or do you want your system to produce 1.5kW? An accredited designer/installer will provide the customer a solar PV system design and specification. This will include things such as: • establishing your electrical loads over an average day using a load analysis • determining the type of panels • determining the size of your solar PV system • deciding the type of inverter • establishing the location of solar panels in relation to angles, available sunlight, shading and temperature. J.P. Teasel version 27/11/2011
Grid Connect • Session 1 Safety Inspections Following the installation of your solar PV system, safety inspections may be carried out by your relevant electrical authority. The Clean Energy Council, the Department of Climate Change and Energy Efficiency and the Office of the Renewable Energy Regulator also conduct its own inspection program. J.P.

Teasel version 27/11/2011
Grid Connect • Session 1 Industry Ombudsman If you have a complaint about your electricity retailer or electricity distributor, you can contact the Energy Ombudsman in your state or territory. For example, the Energy Ombudsman may be able to help if your complaint is about: • The provision and supply of electricity • Failure to provide or supply electricity services • Quality of electricity supply • Billing • Credit and payment services • Electricity disconnections • Connection or transfer issues • Actions of a supplier which affect your property • Metering not working • Billing unfair NSW Energy and Water Ombudsman NSW 1800 24 65 45 J.P.
