Automatic calculation of the specific annual yield with the Sunny Beam
The Sunny Beam calculates the specific annual yield as follows:
• kWh (kilowatt hour) divided by kWp (kilowatt peak) = specific annual yield.
You can find out the value in kWp from your installer.
The value for kWh is calculated as follows:
The total of all daily energy values (E-day), which the Sunny Beam has been provided with
for this year, divided by the number of daily energy values, multiplied by 365 days:
• (E-day 1) + (E-day 2) + (E-day 3) + (E-day n) divided by the number of daily energy
values, multiplied by 365 days = the value for kWh.
Example:
(E-day 1) + (E-day 2)....+ (E-day 250) divided by 250 days, multiplied by 365 days
= x (kWh).
x (kWh) divided by kWp = specific annual yield.
