In 2011, solar plants with a total capacity of at least 26.5 gigawatts (GW) were installed across the globe. In Germany alone, around 7.5 GW of new photovoltaic capacity was added, exceeding even the previous record year of 2010. According to estimates from BSW-Solar (German Solar Industry Association) in Berlin, solar power production will see a further 70% rise in the next four years alone. In order to take full advantage of this capacity in future, the industry needs to address grid stability, intelligent solutions for on-site consumption and efficient, economical storage as a matter of priority.
As the demands on infrastructure increase, so the industry gains new potential for value creation. Only recently, when the latest amendments were made to the Renewable Energy Sources Act (EEG), was the route paved for improving the grid integration of photovoltaics. The new Low Voltage Directive has been in force since January 1, 2012. Inverter manufacturers played a significant role in developing both this directive and corresponding solutions that have integrated mechanisms for controlling effective power. Thanks to the new standard, it will be possible to install significantly higher numbers of PV plants in future and integrate them into the low voltage grid. Even the on-site consumption of solar power and new storage technologies may, in future, also play their part in easing the burden on the grid and boosting photovoltaics’ contribution to energy supply.
There is also potential for small, efficient, distributed battery storage systems to assist in optimizing on-site consumption in residential homes. And for industry and commerce, which have highly consumption-dependent electricity costs, chiefly throughout the day, it is possible that intelligent all-in-one solutions using efficient storage technologies could achieve substantial cost savings. The options for doing so are many and varied, as almost all types of storage open up enormous potential for lowering costs, which in turn makes the use of energy storage systems increasingly attractive.
PV Energy World Special Exhibit showcases latest developments
Following its successful launch in 2011, the PV ENERGY WORLD Special Exhibition at Intersolar Europe 2012 will showcase the hottest developments and pioneering solutions in hall C4, booth C4.230 for the second time. The Special Exhibit is presented by the organizers of Intersolar Europe, Solar Promotion GmbH, Pforzheim, and Freiburg Wirtschaft Touristik und Messe GmbH & Co. KG (FWTM), Freiburg. Within the two thematic areas of Electricity Storage and Grid Integration, the Special Exhibit illustrates the measures, technologies and political conditions necessary to increase PV electricity generation. Expert presentations and panel discussions will also be hosted in the Special Exhibit’s central forum. The Special Exhibit is sponsored by SOLARWATT AG.
