5 Standalone Power Systems Remote Area Projects - Bushlight Australia Source:

6 Grid Connect - Domestic

7 Grid connected PV System Utility Grid PV Modules DC/AC (Grid Inverter) Meter Box / Watt hour meter

8 GC System - Configuration Example

9 Off-Grid PV System (SPS) Charge Controller Inverter AC Load DC Load Source: Applications Remote area electricity Island Site > 0.5km away from grid (i.e. cost of grid N/E extension Vs SPS) Water pumping Important factor: Irradiation Battery Autonomy Charge controller (MPPT)

10 Off Grid Small system SMA Specific Example Source SMA

11 Large Scale System - SMA Specific Example Source SMA

12 12kWh Per Day, SF1 with Diesel back up Sunny Island Sunny Boy SI5048 SB3800 Maximum Solar Power 3,960kW (PV) Battery inverter power Available energy per annum Battery bank Autonomous time Diesel set p..kw 4,384kW h 1100Ah 3 Days. kw Vas Kandiah AOQ SSMBB, V1, 14th October

13 Off Grid Design Philosophy

14 Off Grid Testing & Transport System Testing and transport, E.g. Install equipment on plywood / MDF board (16-18 ) Test equipment and produce reports for compliance Transport equipment and batteries Inverter ~60kg Charger ~ 8kg Batteries ~ 120kg * 2 Allow a total of 400kg for movable mounting system for the office.

15 Data Logging and Communications Source: SMA

16 What do they monitor Daily energy production Annual energy yield in MWh System efficiency (e.g. 85%) CO2 abatement Eg. For PV peak power KWp Average energy generation 136 kwh/day Annual energy generation 49.5 MWh/year 25 year greenhouse gas abatement 1101 Tonnes

17 Provisioning Process Process Top Level

18 Process Partnership Option Overall process accountability Panel Manufacturers/distributors Integrators / Installation Partners Maintenance Partners

19 Standards Solar Power System Provisioning is covered by AS AS 4509 Stand-alone Power Systems (SPS) Parts 1, 2 and 3 AS Secondary batteries for use with SPS - installation & maintenance AS 5033 Installation of photovoltaic (PV) arrays AS 2676 Guide to installation, maintenance.. of secondary batteries in buildings. AS 3011 Electrical installations - Secondary batteries installed in buildings AS 3010 Electrical installations Supply by generating set Vas Kandiah AOQ SSMBB, V1, 14th October

20 Accreditation Provisional accreditation Full accreditation CEC Accredited designers and installers Grid Connect Systems (GC) Stand Alone Power System (SPS) REC requirements above system size X

21 Requirements Analysis and Design Customer requirements analysis Analyse and validate customer requirements Design Design systems to meet all customer requirements Requirements waver from the customer Design meets relevant AS standards Overall design accountability CEC Certified Designer/Installer LV Electrical wiring design accountability - Electrical Contractor

23 Commissioning Customer non technical requirements are satisfied. All functional requirements are tested. Customer user training provided. Customer sign off on installation and training.

24 Maintenance Main GC Equipment Warranty / Failure Rate Electrical & Electronic Equipment Solar Module Warranty - 20Years Inverter SMA < 1% (i.e. for 100 inverters 1 will fail every year) Communications SMA Web box - TBA Routine Maintenance Cleaning of solar panels Frequency depends on location o o o Varies quarterly to once a years Customers Contractors

25 Equipment Mounting System Testing and transport Install equipment on plywood / MDF board (16-18 ) Test equipment and produce reports for compliance Transport equipment and batteries Eg. o o o o Inverter ~60kg Charger ~ 8kg Batteries ~ 120kg x 2 Allow a total of 400kg for movable mounting system for the office

26 Customer Perspective Six Sigma - DMAIC Define Measure Analyse Improve Control

27 Defining the Issues Governme nt Agencies Policy changes Complex REC calculations Entitlement rules Processing delays Customer Residential/ Commercial Customer Service Policies /Regulations Customer contracts Market Conflict Facts on Net Energy Production Facts about ROI Costs variations Quality of work Warranties Solar Companie s Energy Suppliers (Power Companies )

28 Measure - Eg. Audit and Inspection Results Source: 2009 ATRAA Conference

29 Analyse / Improve /Control Phase I Define Opportunity Phase II Measure Performance Phase III Phase IV Analyse Improve Opportunity Performance Define the Issues / Project Describe the Current Situation Analyse and Verify Causes Implement Solution Evaluate Results & Methods Standardise Effective Methods Communicate Results and Future Plans Phase V Control Performance

30 Opportunity The overall Solar PV industry could use a Framework to meet the customer CTQs and 2020 target! Framework Standards Process improvement Methodology (e.g. SS DMAIC) Government programs / Targets Training and Education Stakeholder / Customer Communications
