I don't think anyone knows yet, the more modern ones you buy now have not been around long enough. I think most people assume about 25 years, but time will tell. You probably need that sort of period to achieve payback on the installation cost.
solar energy is why we have life on this planet. However, you want to know about man capturing the energy, and in that respect, we have been rather bad at it. We can capture it with a window, that works pretty good, we get light and heat. We also have several types of solar cells. (Some are an environmental disaster to make, but we assume we can get more out of them in the long haul). With both types of cells, we capture the energy and store it in batteries. It is actually more efficient to capture all that we can, and send it to the power grid, and bypass batteries, etc. That way we dont incur that loss...and then use another power source when that is not enough. -- In the late 80's I worked for a company that installed solar cells, and we told companies the cells would last 50 years...ouch...they didnt last 7...the company that sold them to us LIED....however, it's been years since then, and the materials surrounding the cells appear to be better made, etc. I suspect you should buy high quality, and it will last a long time....but if you put a mirror on it, then it takes a beating like nothing in the lab can simulate.
Most solar panels would last about 25 years Most solar panels would last about 25 years ---------------------------------------------------------------- from www.solarcells101.com Most solar panels are rated 25 years But its hard to say because most of the first solar panels in the 1980s are still putting out power they will have a power loss over time but free power for this long is very cool David www.solarcells101.com
None of the Apollo spacecrafts has solar cells. All of them used fuel cells and chemical batteries to provide energy.
The International Space Station (ISS) is equipped with four solar arrays, which consist of thousands of solar cells. In total, these solar arrays produce around 120 kilowatts of power for the station, utilizing solar energy to support its various systems and experiments. The exact number of individual solar cells can vary, but each solar array typically contains several hundred cells.
Advances in technology - coupled with the discovery of more efficient materials, make today's solar cells much more efficient than earlier models.
There are no energy sources that will never run out, but the sun will last a good long time, so any energy derived from solar will last a good long time. This includes direct solar, such as roof mounted water tanks, conversion of solar to electric by solar cells, bio-solar (grow things which convert to energy), wind, water, earth thermal, and similar.
Solar cells, also known as photovoltaic (PV) cells, typically have a lifespan of 25 to 30 years. Over time, solar panels experience a gradual reduction in efficiency, often retaining around 80% of their initial performance after 25 years. High-quality solar panels can last even longer with proper maintenance, providing renewable energy and reducing electricity costs for decades. Factors like climate, installation quality, and panel type can influence their longevity. Investing in durable solar technology ensures long-term savings and a sustainable energy solution for your home or business. 9396974949
It all depends
where can you buy solar cells

Yes
how are solar cells used in homes
Solar cells have stored solar energy that is converted into electrical energy.
One solar panel typically consists of multiple solar cells. The number of cells in a solar panel can vary depending on the size and type of panel. A standard residential solar panel may contain 60-72 individual solar cells.
