Importance of Plant Power in kWp and Specific Annual Yield
The plant power in kWp (kilowatt peak) is the maximum possible power of the plant. The Sunny Beam
requires the system power in kWp to calculate the specific annual yield (kWh/kWp). The specific
annual yield makes it possible to directly compare PV plants of different sizes. The calculated specific
annual yield indicates the energy yield for the plant size per 1 kWp of power installed.
The Sunny Beam displays the specific annual yield in the Plant view. The Sunny Beam can display the
specific annual yield for the last 31 years. For a new detection of a plant, the specific annual yield of
the last 20 years is displayed. The more years are included, the narrower the columns in the chart will
be.

Requires data from January to December
The specific annual yield for one year is only representative if the Sunny Beam can use data for
an entire year. If your plant was commissioned in July, for instance, there is no data from the
previous months. The present data (from July to December) will then be projected to the entire
year by the Sunny Beam. If the data for at least 330 days (= 11 months) of a year are not
present, the Sunny Beam displays the columns in gray.
