The significance of photovoltaics for a climatically benign energy supply in Baden-Wuerttemberg, a state in southern Germany
- Center for Solar Energy and Hydrogen Research Baden-Wuerttemberg, Stuttgart (Germany)
The contribution to the realization of a climatically benign energy supply in Middle Europe by the inland use of photovoltaics (PV) has been identified to serve as an assessment for political decisions. The roof area of Baden-Wuerttemberg is large enough to install a total PV power that generates at least 20% of the consumed electricity. For this share, the fluctuations of PV power do not cause more than 2% of the total electricity to be unused if no storage systems are used. The small size of the current world market for PV systems, as well as the comparably high prices for PV electricity will impede a fast extension of grid-connected PV systems mid-term. Therefore, public subsidies will still be needed to accelerate both demand and supply of PV systems. Given these boundary conditions a scenario where no more than maybe 100 MWp will be installed until the year 2005 is most probable. Then, the share of the electricity generation by PV will only be in the 0.1% range. Logistic functions for the PV market after the year 2005 show that only if they start to support the integration of PV systems in the electricity system already today, shares of the PV electricity in the 10--20% range will be obtainable around the year 2020.
