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.
It is also important to note that most inverters come with a life-expectancy of approximately 10 years, which is much shorter than the life of the panels themselves. Panels normally last 25 to 30 years. As a result, most inverters need replacement after about 11 years of service. Replacing an inverter is usually the most expensive aspect of a solar system, with replacement costs ranging between $3,000 and $20,000 each time. However, a long term solar warranty can be purchased to cover this cost.
