How can I achieve optimum energy yields?

Some of the factors that dictate the energy yield for a PV system cannot be influenced. This includes natural conditions such as the number of hours of sunshine and the intensity of the sunshine as it falls on the PV system's location.

The radiation volume in Germany totals between 981 and 1200 kilowatt hours (kWh) per square meter and year. That's the same amount of energy that is produced by 100 liters of fuel oil.

Having these conditions it is possible to achieve optimal capturing of the energy. That means that the existing sunlight should hit the solar cells optimally to enable as much of the sunlight as possible to be converted into useable electrical energy. This requires professional evaluation and meticulous layouting by a qualified PV systems technician.
