Photovoltaic power stations
Main article : List of photovoltaic power stations
Solar power in Germany consists almost exclusively of photovoltaics (PV) and accounted for an estimated 6.2 to 6.9 percent of the country's net-electricity generation in 2016. About 1.5 million photovoltaic systems were installed around the country in 2014, ranging from small rooftop systems, to medium commercial and large utility-scale solar parks. :5 Germany's largest solar farms are located in Meuro, Neuhardenberg, and Templin with capacities over 100 MW. Germany has been among the world's top PV installer for several years, with total installed capacity amounting to 41.3 gigawatts (GW) by the end of 2016, behind only China. However, new installations of PV systems have declined steadily since the record year of 2011. It's estimated that by 2017 over 70% of the country's jobs in the solar industry have been lost in the solar sector in recent years. Proponents from the PV industry blame the lack of governmental commitment, while others point out the financial burden associated with the fast-paced roll-out of photovoltaics, rendering the transition to renewable energies unsustainable in their view. Germany's official governmental goal is to continuously increase renewables' contribution to the country's overall electricity consumption. Long-term minimum targets are 35% by 2020, 50% by 2030 and 80% by 2050.:6 
The country is increasingly producing more electricity at specific times with high solar irradiation than it needs, driving down spot-market prices and exporting its surplus of electricity to its neighboring countries, with a record exported surplus of 34 TWh in 2014. A decline in spot-prices may however raise the electricity prices for retail customers, as the spread of the guaranteed feed-in tariff and spot-price increases as well. :17 
As the combined share of fluctuating wind and solar is approaching 17 percent on the national electricity mix, other issues are becoming more pressing and others more feasible. These include adapting the electrical grid, constructing new grid-storage capacity, dismantling and altering fossil and nuclear power plants - brown coal and nuclear power are the country's cheapest suppliers of electricity, according to today's calculations - and to construct a new generation of combined heat and power plants.
