As the object is moved in front of the Pixy, the data stream will print out the x and y coordinates, along with the object height and name. You can capture the data to a text file using standard Linux command-line redirection. For example: sudo ./hello_pixy > data.txt. A portion of the output I captured from the Pixy is shown in Listing 2.
Solar panels typically last between 20 to 30 years with many producing energy beyond that timespan. Lavrova notes that many systems installed as early as the 1970s are still producing power, albeit a little less than when they were brand new.
The warranty conditions for PV panels typically guarantee that panels can still produce at least 80% of their initial rated peak output after 20 (or sometimes 25) years. So manufactures expect that their panels last at least 20 years, and that the efficiency decreases by no more than 1% per year. What makes talking about lifetimes for PV panels difficult is the fact that very few panels have been installed for long enough.
