1 Soar Roof Top in Thaiand

2 Presentation outine 1 Soar potentia in Thaiand 2 Technoogy and system overview 3 The project deveopment process Soar Systems in Thaiand - Opportunity and Market Deveopment 4 5 Key components of a PV Key risks/issues to beware of and the mitigation measures, particuary in Thaiand 6 Case studies on PV project deveopments 2

3 Soar Power Goba variations in irradiation 3

4 Soar Power PV appications The photovotaic technoogy can be used in severa types of appications: Grid-connected domestic systems Consumer goods Off-grid systems for rura eectrification Off-grid industria appications Grid-Connected Power Pants Soar Farms aso known as PV farms, BIPV and roof- top PV systems or so caed argescae centraized PV grid connected systems produce eectricity from the sun and se the eectricity to the utiity grid. 4

5 Soar power The PV project deveopment process 10 good reasons to switch to soar photovotaic eectricity 1. The fue is free 2. It produces no noise, harmfu emissions or pouting gases 3. PV systems are very safe and highy reiabe 4. The energy pay-back time of a modue is constanty decreasing 5. PV Modues can be recyced and therefore the materias reused in the production 6. It requires ow maintenance 7. It brings eectricity to remote rura areas 8. It can be aestheticay integrated in buidings (BIPV) 9. It creates thousands of jobs 10. It contributes to improving the security of Asia's energy suppy 5

6 Soar Power Genera considerations for arge scae PV projects 6

7 Soar Power The PV project deveopment process 1 st Step: Pre-Deveopment Find reiabe power purchaser and/or markets Determine the pre-feasibiity and expected output Obtain a icenses ike for exampe: PPA, grid connection and other oca icenses Secure the and; buy or ease decision 2 nd Step: Technica Seect the most efficient technoogy for the chosen ocation Find a reiabe turn-key contractor Obtain binding proposas Seect a suppiers and contractors 3 rd Step: Finance Prepare a fu feasibiity study and business pans Estabish access to capita and banks Sign a finance reated contracts Sign EPC contract and order a components 4 th Step: Impementation System instaation Secure agreements to meet a O&M needs Connect the system to the grid Finaize a documents and approvas to start the actua eectricity saes 7

8 Soar Power Keep it simpe and sustainabe Environmenta friendy: for each kwh of eectricity produced, 0.5 kg of CO2 are avoided Virtuay maintenance free and reiabe technoogy providing with predictabe and un-interrupted output for more than 20 years soar radiation photovotaic modues direct current inverter aternative current pubic grid 8

9 Soar Power Modues Modues Wafer technoogy 90 % market share Thin-Fim technoogy 10 % market share Other technoogies Mono-crystaine Efficiency = 16% Poycrystaine Efficiency = 14% A-SI:H Efficiency = 6-9% Micro-Crystaine Efficiency = 8% CdTe Efficiency = 10 % CIS Efficiency = 7-12% 9

10 Soar Power Centraized or decentraized system design? Decentraized System Design Suitabe for systems in the ower MW range Easy to insta Less compicated to maintain Especiay suitabe for systems with different integrated soar generator types High output efficiencies Centraized System Design Suitabe for systems in the muti-mw range More cost efficient for arge scae power pants Especiay suitabe for systems with homogeneous soar generator types High output efficiencies 10

11 Soar Power Mounting systems Fix system 1-axis 2-axis Output 100% 115 % 125% Occupied area 100% % 200% Maintenance Cost 100% 106% 120% 11

12 Soar Power Monitoring and contro Monitoring of centra inverters, tracking system and connection boxes Readout of inverter and string data Shows system status of a components and initiates aarm Internet porta Anaysis software Aarm function 12

13 Soar Power Key risk factors and mitigation strategies for PV projects in Thaiand Project Phase Key Risks Mitigation Strategies Technica Specia component certification requirements by the oca authorities Grid-connection reated probems Component suppy shortages Seect ony components which fufi a oca requirements Buid a cose reationship the oca grid owner Use strong suppiers and EPC partners Financia Banks have imited experiences in PV debt financing, structures and risks Specia country reated documentation is normay needed There is ony a imited amount of equity investors for PV projects in Asia Eary reationship buiding with the bank is crucia Detaied, creditabe and in-depth documentation Eary reationship buiding with possibe equity partners is a crucia Government Loca suppiers coud be protected by high duties or other reguations High country and poitica risks Higher risk for sudden changes in the subsidy poicies Use of oca suppiers for keycomponents Use of oca banks and investors Use of oca government funding and support 13

14 Soar Power 24MW SinAnSoar PV power pant case sampe Location: Sinan-gun, Jeoa-do, South Korea Project Area: 660,000 m2 Annua Output: 33,000 MWh/ 7,200 HH equivaent System Type: Singe Axis Tracking System Modue Type Conergy 180W Crystaine 108,864 modues 3rdParty 200W Crystaine 21,792 modues Construction Period: May 2007 through September 2008 EPC Contractor: Dong Yang Engineering The SinAnpower pant is the argest PV faciity in South Korea The word s argest soar power pant with tracking systems. 14
