#The Energy over the interval is calculated as <math>{SolarRad} \times {Interval} \times 60</math> to get the energy in Ws and summed up to the total for the day.
#At the end of the day the total energy sum in Ws is converted to KWh by <math>{the\ energy\ sum} \div {3600 \div 1000}</math>
NOTE: during this process the actual calculation of the solar hours is also executed. All calculation are done in one pass. The creation of the actual charts data consists merely of the selection of the data from the resulting list.
