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
Do you save more money if you use solar energy?
Yes, you will save more money after the initial cost. Solar panels will last close to 25 years.
Do solar panels get more heat from the sun?
No, solar panels do not create heat they create energy
Do solar panels use more power to produce them then they will ever provide in their lifetime?
No, the energy payback time for solar panels is typically within 2-4 years, meaning they will produce more energy over their lifetime than was used to manufacture them. After this period, solar panels operate efficiently for many more years, generating clean, renewable energy.
Is solar panel an expensive or cheap method to use?
It depends. If you only use solar panels for a little bit of time they seem very expensive but if you use solar panels for years and years they seem less expensive. If the prices stay the same they do now, in 15 years solar panels would still cost a bit more than regular energy but the keyword is if. Since there will be more demand in energy and less supply of fossil fuels the prices of those will probably rise. Also since there will be more demand for energy, solar panels will probably cost more to install in the future than now.
Why are solar panels dark?
solar panels are in black and in dark blue color because they absorb more energy
How expensive are solar panels for a home?
Solar panels range from 200 dollars to thousands. It depends on how much energy you want to generate and how big the solar panels are. Bigger panels make more energy, and they cost a lot more. But once you buy it, you won't have to pay for electricity bills.
Where can I find more information on installing solar panels?
This website contains much info on installing solar panels. http://www.solarpanelinfo.com/
Why do solar panels have to face the equator?
Solar panels are most efficient when facing the equator because that is where the sun's rays are most direct, providing the most energy. By facing the equator, solar panels can capture more sunlight throughout the day and generate more electricity.
How can you use solar panels as a renewable recource?
Solar panels are not a renewable resource, unless you recycle them. Solar panels make electrical power from solar energy, but it in no way replenishes the Sun to make more solar energy in the future. However, the Sun does rise every day, and when it's not cloudy the electrical energy produced by the panels is reinstated.
How can we make solar power more affordable?
As more people buy solar panels the price comes down.
Is solar energy widely accepted?
Not as Much as Wind, Because Solar Panels Cost More Than Wind Turbines , If the Two Create The Same Amount Of Energy The Solar Would Have Costed More to produce the Panels.
