Wxcwl spreadsheet of solar panel irradiance vs power.

Florida solar energy center irradiance temperature pv output page 2 procedure 1. Lead a discussion on findings from the photovoltaic orientation power output activity and answer any questions that the students have from the problem set. The efficiency of solar panels depends on the amount of light the panels receive at their location or solar irradiance. Solar panels collect light from the sun to turn it into electricity.

Solar irradiation reaches the earth in three different. These predicted values are obtained using standard test conditions 1000 w m2 irradiance 25 c cell temperature and 1 5 air mass ratio. The local and solar times as well as the date entered in the previous sheet are shown in the box above the green cells as a reference. On days when the sun is direct overhead shining bright you will have high irradiance and your solar panels will generate more solar energy.

The spreadsheet takes into consideration the information entered and the total insolation available to predict voltage current power and efficiency values for that solar panel. Solar panels must be taken into account because sunlight can reflect off of a surface onto a tilted panel and alter the total solar irradiance collected.
