Graph of the Day: Solar grid parity in 102 countries

Print Friendly

Here’s an interesting graph used by Suntech’s Stuart Wenham (sourced from Applied Materials) during a presentation at the Solar 2013 conference in Melbourne on Thursday. It highlights the extent of “grid parity” for solar PV across the world – it is now in 102 countries.

This definition of “grid parity” is the cost of rooftop solar versus the cost of electricity sourced from the grid – this is sometimes known as “socket parity”. Most of the countries – though not all – are those with good solar resources and relatively high electricity pricesAustralia reached “socket parity” several years ago.

Wenham says that solar PV will fall a further 50 per cent in costs up to 2020 – see our story today. He says that solar PV at a utility level will also challenge fossil fuels – as it already does in those with high gas and diesel costs, and will offer the cheapest avenue to countries which have little electricity infrastructure.

    It is actually “105 countries”, covering 98% of the world population.

    German atomic power plant owners threaten to close their plants prematurly because they can’t compete against PV/RE anymore:

      “German atomic power plant owners threaten to close their plants prematurly because they can’t compete against PV/RE anymore:”

      Dr. Amory Lovins and Dr. Hermann Scheer have been predicting the demise of nuclear power, on financial grounds, for many years.

      Good to see, that they were right all along.

      No serious energy expert, predicts a revival of fossil fuels these days, anymore.

        We had a reactor shut down in the US on May 7. Was losing money. A short time earlier another reactor announced which was off line for repairs announced that it would not be coming back. We’ve got other reactors losing money and others off line, possibly not to return.

        Natural gas is probably the big contributor here to the demise of nuclear plants, but wind and solar are going to be the long term killers. Wind will drag the off-peak price below cost of production and solar will pull down the profit ceiling to the point where nuclear can’t cover its late night losses.

      California is second. Hawaii is also a state and has incredibly high electricity prices because most generation is done with oil. (Coal is too expensive to ship.)
