Last November was warm in Germany, but relatively sunless. Nevertheless, the energy yield from photovoltaics fell only slightly short of the targets. There were larger shortfalls in wind energy. "The fluctuations are not unusual and should be made up in the coming months", says Markus W. Voigt, CEO of aream Group. "In the longer term, shortfalls will be offset by overproduction."

The sun showed itself rather rarely last month, even for a November; on average, it shone about one fifth less than the long-term average. Nevertheless, solar energy production in Germany reached 96 percent of the target value. The situation was similar in southern Europe: In Spain, the yield in November remained seven percentage points below target, while in Italy the shortfall was one percentage point more.

Despite some turbulence at the end of the month, November was also rather calm overall, with the wind blowing moderately. As a result, the wind energy yield in Germany reached 73 percent of the target value. Year-to-date, this results in a target achievement of 84 percent, one percentage point lower than in October.

"Investments in renewable energies not only serve environmental protection and support future-proof technologies", says Voigt, "In addition, investments in tangible assets are relatively crisis-proof and stable." Short-term events that cause stock exchange prices to jump generally have little impact on them. However, since the weather and thus the energy yield change, investors should hedge their returns through broad diversification. Those who focus on different countries and forms of energy can leverage the return potential of renewables while curbing risk.
