Solar panels to solar power in Germany often clean?

This is usually based on photovoltaic (pv) of the project location. Generally speaking, the winter often wash, summer wash less. Often keep the panels clean can greatly improve the efficiency of power generation. In order to ensure the normal power, photovoltaic power station solar panels are generally a month to clean a

this is usually based on the location of the pv project. In general, often wash in the winter, summer rarely wash. Always keep the panels clean power generation efficiency is improved greatly.

Every place is different, the heavy rainfall for a month every place is different, so to a fixed value is not conform to the actual situation. If the condition allows, you can make a comparison: if a panel is often clean, and the other panel is not clean, is the power of two panels are low. If the difference between the two pieces of panel capacity of more than 3% every day, you will need to clean.
