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.
How long will a solar system last? Our systems are guaranteed for 25 years, though they have been known to perform for over 45 years. A solar system adds value to your home with no increase to your property tax. Your energy use and the size of your solar energy system will determine your actual savings amount. With little or no startup costs, systems start paying for themselves immediately and increase each year as the cost of electricity rises. A typical return on investment is usually about 15-20%.
