The German PV market has developed over the last two decades to be one of the most sophisticated PV markets worldwide. With more than 1.4 million PV systems, a total electricity consumption share of around five percent (29.7 billion kWh) was produced in 2013. The majority (70 percent) of the new systems installed in 2013 were smaller than 10 kWp – making Germany by far the largest residential consumer market in Europe. The potential rooftop area in Germany alone would allow an installed capacity of around 200 GWp. Thus, Germany together with other European markets is expected to continue leading the global rooftop PV market in the next years. IHS research predicts new annual PV installations in Germany between 2 and 3.5 GWp in the coming years.
New business models are being used and further developed to build the base for an economic operation of PV systems outside of the feed-in tariff scheme. This opens up a window for new markets and technological innovations. The large pool of installed PV systems is one pillar for the development of the energy storage systems market. PV-battery systems could reach an annual installation volume of more than 100,000 systems by 2018, according to EuPD research. But also retrofit storage installations will be a major driver to improve energy autarky in private households and commercial operations.The inverter market continues to profit from the large base of existing PV installations in Germany, as well as new inverter systems, such as hybrid or micro inverters for new PV systems. Furthermore, innovative data management systems and new tools to optimize the efficiency and operation of PV systems are promising fields for this new PV market.
