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.
They specifically delved into what's known as payback: how many years of operation does it take for a solar panel to generate as much energy as was used in its manufacture? They found that depending on the technology used, it takes between one and four years for solar panels to earn out on their energy debt.
