UBS: Boom in unsubsidised solar PV flags energy revolution

By Giles Parkinson on 23 January 2013

According to analysts from the global investment banking giant UBS, the arrival of socket parity – where the cost of installing solar is cheaper than grid-sourced supplies – is about to cause a boom in un-subsidised solar installation in Europe, and the energy market may never be quite the same again.The revolution in energy markets caused by the growing impact of rooftop solar PV is about to take a dramatic leap in scale.

Such forecasts have long been the province of environmentalists, climate activists, university researchers, and the occasional industry leader, such as David Crane, the head of NRG, the largest generator of electricity in the US.

Now, the team of energy analysts from UBS, writing in response to plunging power prices in Europe, has issued a stunning report entitled “The unsubsidised solar revolution” – suggesting that investing in solar will become a “no brainer” for households in several European countries, and will have profound implications for the incumbent energy industry.

“Solar has turned from a heavily-subsidised marginal technology into a mainstream source of power generation,” the UBS analysts write. ” “Thanks to significant cost reductions and rising retail tariffs, households and commercial users are set to install solar systems to reduce electricity bills – without any subsidies.”

Here’s a graph to illustrate what they mean. It shows the light blue line at the top, which indicates where grid-based electricity costs are heading.

The dark blue line indicates the cost of solar PV – it’s now at an inflection point in southern Germany and will get cheaper.

But PV with battery storage, while more expensive now, will cross over in 2014 and ultimately deliver the biggest savings.

UBS  says this means utility customers will effectively become utility competitors. It estimates there could be 80GW of unsubsidised solar installed in Germany alone.
