1 Solar Power Overview REROC Off the Grid - 14 November 2013 Edwin Foong GM Business Development, SOLEIR

2 Types of Solar Power Heat Solar Thermal High Temperature Utility scale power plant Low Temperature Hot water service Light Photovoltaic Flat plate Silicon Thin Film Concentrated

3 Solar Thermal Power Generation For large utility scale applications Concentrates heat energy from sunlight using mirrors & trackers Reliant on direct sunlight ( blue sky ) heliocsp.com Central Tower Parabolic Trough Jc-solarhomes.com

4 energyandresources.vic.gov.au Solar Thermal Power Generation Aim to achieve high temperatures with most efficient mirror/piping arrangement Most famous are 3 large SEGS plants in California 354MW combined Parabolic trough design Built between Dish dreamstime.com Compact Linear Fresnel Able to store heat energy for generation after the sun goes down

5 Solar Thermal Low/Med Temperature Flat plate & evacuated tube solar collectors Low temperature Hot water service Building space heating Swimming pool heating Medium temperature Process heat drying, steam, commercial laundries Absorption chillers poolheatingsydney.wordpress.com Evacuated tube solar collectors greenhomesrealtorsdcmetro.com/green-homes/

6 Photovoltaic Converts photons (light energy) into DC electricity Flat Plate Mono & poly-crystalline Silicon Thin Film For general applications Concentrated PV Less PV material More exotic PV materials Additional cost of mirrors/lenses Additional cost of tracking Requires cooling (co-generate heat) For blue sky regions

7 Photovoltaic Fixed Tilt vs Tracking Tracking System Rotates panels to face the sun Increase energy production Increase cost and O&M Fixed Tilt Tilt angle based on latitude Simple, low cost choyosolar.com pv-magazine.com

8 Solar Feed-in Tariffs NSW Solar Bonus Prior to 27 Oct 2010: $0.60/kWh for renewable energy exported 28 Oct 2010 to 28 April 2011: $0.20/kWh Solar Bonus Solar Bonus Scheme closed on 28 April 2011 Unsubsidised FIT today is set by retailers IPART recommends between $0.066-$0.112/kWh for 2013/14 Customers today mainly benefit from offset electricity consumption And renewable energy certificates

9 Renewable Energy Target Renewable Energy (Electricity) Act 2000 Renewable Energy (Electricity) Regulations 2001 Administered by the Clean Energy Regulator Sets a requirement on Liable Parties to purchase renewable energy Electricity retailers Wholesale electricity purchasers At the end of 2010, the RET was split into two parts: Large-scale Renewable Energy Target (LRET) Small-scale Renewable Energy Scheme (SRES)

10 LRET For large power stations PV plants over 100kW Annual target Gradually increases to 41,000 GWh by 2020 Then remains at 41,000 GWh until 2030 Requires additional 8-10GW of renewable energy plants Eligible to create 1 LGC for every 1 MWh of electricity Value of LGC has fluctuated from $10-$60 in the past Capped at the penalty rate of $65/LGC ($92.86 after tax)

11 SRES For PV up to100kw and Solar Hot Water (SHW) systems SRES target is set annually to match the expected installations Eligible to create 1 SGU for every 1 MWh of electricity PV Can receive up to 15 years of deemed SGU s SHW Create SGU s for displaced electricity (in MWH) over its lifetime Value of SGU fluctuates but tends to stay under $40/STC

12 How to get involved with solar Install own solar power systems PV Generate electricity for own use (behind the meter) Install PV panels on available roof space Use PV panels to provide shade above car parks Thermal Hot water service Absorption chillers possible, but up against PV + split system AC

13 How to get involved with solar Direct purchase system Create and sell renewable credits directly or assign to agent Emerging solar leasing options - $0 up front Invest in commercial and utility scale schemes Community funded Managed investment schemes Purchase output from solar farm by others

14 Examples of Solar in Government & Business Sunshine Coast Council 158kW of PV installed at libraries, community halls, visitor centres holiday parks, reserves, club houses. Developing a 10MW solar farm at Valdora Dubbo City Council Leasing council owned land to SOLEIR to develop 2.5MW solar farm Soleir.com.au Soleir.com.au

15 Examples of Solar in Government & Business Randwick Council 24 kw solar 24kW solar installed on Maroubra Depot rooftop Installed in 2009 Provides 25% of the depot s electricity demand ecogeneration.com.au

16 Examples of Solar in Government & Business Echuca Hospital (VIC) solar thermal chiller Evacuated tube solar thermal collectors Heat water to power 500kW absorption chiller 10,000 lt storage 311 MWh p.a. capacity Installed in 2011 ecogeneration.com.au

17 Future for Solar Solar Thermal Continuing development of mirrors and solar collectors Hybrid applications with thermal power plants Lower cost thermal storage technologies PV Flat plate PV costs fallen by 80% since 2008 Cost continue to fall but at more sustainable rate Emerging storage technologies Widespread adoption has the potential to change the way we use the grid
