Depends on the quality and how you treat solar panels. Generally, solar panels normally last from 20-30 years treated well enough, but for 50 years, you need to get a REALLY good quality solar panels. Average solar panels, last for about 20 years. Good panels can last for 50 years, but that is hard.

What is automatic solar street light?
Solar street lights are raised light sources which are powered by solar panels generally mounted on the lighting structure or integrated into the pole itself. The solar panels charge a rechargeable battery, which powers a fluorescent or LED lamp during the night. Most solar lights turn on and turn off automatically by sensing outdoor light using solar panel voltage. Solar streetlights are designed to work throughout the night. Many can stay lit for more than one night if the sun is not in the sky for an extended period of time.
How computers have changed in the last 100 years?
The biggest changes, I would say, is that computers got smaller and smaller and more and more powerful. (Of course, real computers aren't 100 years old yet.)
How computer technology has impacted the United States in the last thirty years.?
Transformed us into a more mobile, better connected network.
What are the Advantages of solar panels?
by using solar clees their is no pollution it is eco friendlyThey have no moving parts and hence require little maintenance and work quite satisfactorily without any focusing deviceIt does not cause any environmental pollution like the fossil fuels and nuclear powerSolar cells last a longer time and have low running costsAnswer:Anytime you can harness the sun's energy, you are tied into the most powerful source of energy available anywhere. Solar cells are getting more efficient all the time. These solar cells can be used in so many ways. When at Costco the other day, I saw solar cells that can be taken with you when camping. These cells can be stored in a device that also inverts that energy to AC if needed. You can run all kinds of lights and devices, including your computer.The advantage of using solar cells at home or in a business are many. You can actually produce more energy than you use. When this happens, the extra feeds back into the grid and you are paid for it. It's fun to see your power meter actually run backwards. With all the tax incentives, a solar system can pay for itself in as little as five years. With electric rates constantly rising, that could be worth a small fortune to you in the long run.
Which is the best way to make resources sustainable?
use more solar power
