According to a study by the Fraunhofer Institute for Solar Energy Systems ISE commissioned by Agora Energiewende, solar energy will become the cheapest power source in many parts of the world. By 2025, solar power in sunny regions will be cheaper than power from coal or gas.

February 2, 2015
The German Fraunhofer Institute for Solar Energy Systems ISE and the US National Renewable Energy Laboratory, NREL, have compiled a study that describes the status of both the current market as well as the state-of-the-art for concentrator photovoltaic (CPV) technology. This young technology has achieved tremendous progress and has the potential for delivering solar electricity at a cost-competitive level in sun-rich regions with high direct irradiation values. The study gives an overview of all installations bigger than
1 MW, also of all companies active in the field of high and low concentration technologies as well as of efficiency values and the levelized cost of electricity. The study will be updated every half year.

Last updated: January 7, 2015
Germany is leaving the age of fossil fuel behind. In building a sustainable energy future, photovoltaics is going to have an important role. The following summary consists of the most recent facts, figures and findings and shall assist in forming an overall assessment of the photovoltaic expansion in Germany.
Fraunhofer ISE publishes "Photovoltaics Report"
Last updated: October 20, 2014
On average, installations have grown by 44 % annually in the period from 2000 to 2013.
The intention of this presentation is to provide up-to-date information. However, facts and figures change rapidly and the given information may soon be outdated again.
Study: Levelized Cost of Electricity - Renewable Energy Technologies
Dipl. Wi.-Ing. Christoph Kost, Fraunhofer ISE 13. November 2013
The study compares the present costs for conversion of different energy forms into electricity and gives a prognosis for the further cost development up to 2030. The scientists in Freiburg analyze both the levelized cost of electricity (LCOE) from renewables as well as from conventional energy technologies. They present comparative figures for new power plants constructed in Germany, which are based on solar, wind energy and biogas as well as brown coal, hard coal and gas.
Solar Power Plants Deliver Peak Load
Statement Prof. Bruno Burger, Fraunhofer ISE
Freiburg, June 2011 (last update: January 2012)
The comfortable weather of the past weeks lured many outside. However, not only those looking for sun benefited from the beautiful weather, also solar power plants operated particularly well and delivered an important contribution to the power supply. Graphs based on data from the European Electricity Exchange (EEX) show that, depending on the weather, over midday up to 13.2 Gigawatts (GW) of solar power was delivered to the public grid. That corresponds to the net output power of up to ten nuclear power plants.
Solar power plants thus relieve the conventional power plants and significantly reduce the peak power demand. At the moment, in Germany, only four of the 17 Nuclear power plants are operating, therefore solar plants play an important role in a secure power supply. They absorb the peak loads during the day, thereby allowing the conventional power plants to operate with an almost constant power from 7am to 10pm.
The figures 1 and 2 show the planned and actual power production from solar, wind and conventional power plants on Sunday and Monday the 8th and 9th of May 2011. These figures show how well the predicted and actual production agrees.
Figure 3 shows the electricity production over one week. The following figure shows the production over one month. All figures show that solar power is a reliable producer and that it can deliver valuable peak load power. One can also see that every day during this week the complete midday peak load was covered by solar power. The conventional peak load power plants were significantly relieved.
According to Prof. Dr. Bruno Burger from the Fraunhofer Institute for Solar Energy Systems ISE in Freiburg the figures show that the contribution of solar power is very predictable and steady, revealing no rapid changes, as can occur for example, with wind power. “The reason is the large spatial distribution of the solar plants, where local weather conditions, such as moving clouds, are averaged out completely”.
