There really isnt much more to this story than what the title title says. Germany has heavily embraced renewable energy, especially solar power, in every appliciable measure.
Lets see how….

Germany generates enough power from the sun’s rays to meet the needs of households in a city of 590 000, according to the Solar Energy Association BSW.

Last week, a solar electric power plant, billed by its operators as the world’s biggest, went into service in the southern German state of Bavaria. More than 1 400 movable solar modules will collect the sun’s rays and harness them into energy for around 3 500 homes.

Germany accounts for 60% of the world market in solar energy, with some 5 000 firms exporting one-quarter of their products in a sector that employs 45 000

Germans last year invested €3.7bn in solar energy, one of the fastest growing sources of renewable energy along with wind power and biomass. Solar energy accounts for less than 1% of the country’s energy needs, but the figure is expected to grow to more than 5% by 2020, according to the BSW.
