What means the sun symbol in my graph in the efficiency graph ? (my outputs daily view).
thanks,
The sun symbol is shown whenever the weather condition is set to “Fine”. The weather condition is calculated as follows (from help):
The weather condition is automatically updated throughout the day for live systems that use the Add Status and Add Batch Status API. It is based on system efficiency (kWh/kW) or the amount of energy generated divided by the system size.
The time of the day also affects the calculation. The following rules are applied by the end of the day.
Greater than 5.0kWh/kW - Fine
4.0 to 5.0 - Partly Cloudy
2.5 to 4.0 - Mostly Cloudy
1.0 to 2.5 - Cloudy
0.0 to 1.0 - Showers
If the system has estimated output data (see below) the conditions calculations are based on the percentage of the estimated output -
Greater than 90% - Fine
60% to 90% - Partly Cloudy
40% to 60% - Mostly Cloudy
20% to 40% - Cloudy
Less than 20% - Showers
When a system produces 90% or more output than the daily estimate, the condition assigned would be ‘Fine’. This gives the flexibility to handle seasonal variations in output for individual systems.
