Energy Payback Time

The International Energy Agency Photovoltaic Power Systems Programme (IEA PVPS) has published some very interesting documents showing the energy payback time of PV in different locations around the world.

Most relevant for Perth: The Australia page from the summary brochure of the IEA study (extracted with permission). See the full brochure (warning 5MB download) to confirm for yourself that Perth has a record low energy payback time of 1.59 years (page 6) for a roof mounted PV system when compared to all other places that were part of the study.

The actual report entitled "Compared assessment of selected environmental indicators of photovoltaic electricity in OECD cities" is a very detailed document explaining all the methods used. It is the source of the graphics on our 'details' page.

Many more interesting reports from the IEA about PV can be found by browsing their website here.

CO2 Intensity or Energy Sources

The AGO publishes (and regularly updates) the so called 'Factors and Methods Workbook'. Here you find the 2008 edition. Page 16 of this very detailed document shows a table comparing electricity in different states.

What the Future holds

Future of Photovoltaics

Nanosolar promises to revolutionize the way solar cells are made. They simply print them! They do that a cost far below what was thought possible and expect a factory door price of below $1 per Watt (that is only between 30% and 50% of the cost currently achievable with other technologies). They have started mass production and the first large scale installation of their product is currently under way in Germany.

Tesla Motors brings fun back to driving for the ecologically aware of us! Powered purely by electricity from the grid (and if you have a grid connect PV system on your house from renewable sources), this car is in the same performance category as Porsche and Ferrari - at a price that is lower! Nevertheless it offers 220 miles per recharge! For the near future Tesla Motors plan to offer additional models, more suited to the family market.
