1. Example Analysis
1.1. Location DescriptionGPS Coordinates: 32.725513 Latitude, -117.13492 Longitude, 73.5Altitude
System Parameters: 50.0kW, fixed-axis with 0.0 degree tilt and 180.0 degree azimuth
Time Zone: America/Dawson
Winter Solstice Day Length: 9.9Hrs.
Summer Solstice Day Length: 14.2Hrs.
1.2. Solar Path
1.3. Shading Losses
The total yearly sun hour losses are 22.9% due to shading.
1.4. System Output Results
The total estimated system output of this location is 50317.9kWh/yr. Without shading there is a total
possible output of 67991.2kWh/yr. At this location you will loose 17673.3kWh/yr or 25.9% due to
shading.
2. Results Analysis
2.1. Analyzing the resultsThe solar path graph illustrates the path of the sun. 180 degrees is due south and 0, 360 degrees is due
north. The Shading losses chart illustrates the percentage of monthly hours lost due to shading in
respect to the total possible hours over the horizon. These two graphics should be used in conjunction
with each other. There may be significant hours lost in the morning or late afternoon, however, this
does not necessarily mean the location is not conducive to solar power.
The system performance calculation has been undertaken using estimated values for array
orientation, inclination or shading. Actual performance may be significantly lower or higher if the
characteristics of the installed system vary from the estimated values.
