NABCEP - MUST Know - STC*

Learn the first of the 4 things you MUST know before taking the NABCEP PV exam - Standard Test Conditions. View this PowerPoint topic and learn more at http://SolarProfessor.info. NOTES: Be sure to "reality check" your work on any NABCEP questions. For the example problem given in this video, the reference cell is measuring 600 W/m2 and the module is producing 200W, so when the questions asks what will the wattage be produced at 1000 W/m2, just take a second to check your thoughts (your "reality check") and understand that after your calculation is complete the answer should be greater than the 200W. If it isn't, recheck your math. NOTE: There is a mistake with the math of the equation in the video. The correct calculation should be: 200W / .60 = 333W Also, using a reference cell meter, consider the time of day and angle your array is towards the sun. On a summer day around solar noon in your area of the country I would expect the meter to read about 1000 W/m2 or above if you point it directly at the sun. But be sure if you are testing your system, you are pointing it at the same angle as the array. I usually just set it on a solar panel to test.
