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.
