Solar Photovoltaic Presentation to the

2008 Electrical Industry Leaders Forum Victor De Sousa – BP Solar26 August 2008

How does solar PV work?

• Solar photovoltaic cells are solid-state semiconductors

• Light hits the cell, freeing electrons in the silicon which, with enough energy, move through the silicon and into an external circuit.

3

The lifecycle of a solar panel

Raw silicon

Silicon wafer is converted into a

solar cell

Multiple cells are use to form solar

modulesMultiple modules installed to form an array

Silicon is cast into ingots and sliced into

wafers

4

How are solar panels installed?

Retrofitted to existing roofs

5

How are solar panels installed?

On an array structure, usually ground-mounted

6

How are solar panels installed?

Integrated into the fabric of a building:

7

How is solar energy used and stored?

• Grid-connected solar

• Stand-alone solar

BSCE Accreditation

• The aims of the BCSE Industry Accreditation scheme are:

1. Gives customers increased confidence in the design and installation work.2. to improve the safety, performance and reliability of renewable energy systems installed.3. to encourage industry best practice 4. to provide a network of competent systems designers and installers.

• Pre-requisites for accreditation include:

− Satisfactory completion of a industry training course

• Find out more at www.bcse.org.au

18

Industry vision for a solar powered nation

• A nationally consistent gross feed-in tariff (paid on all generation, not just excess) would propel the Australian solar industry sustainably and produce the following results:

− 3GW of new peak energy generation capacity

− Saving of 4 million tonnes of GHG pa

− Spark major private investment in energy infrastructure

− Create a green collar workforce of more than 9,000 jobs

− Build an industry at scale to drive down cost for the long term
