What doesn't fit here?
The core of the story has to be technology focused.
- If article mentions "AI" in a sentence and then talks about business economics that doesn't make it tech news.
- Gaming is too many layers removed from technology. There are many dedicated communities that are a better fit for it.
- Transporation is too many layers removed from technology. EVs while use many cool technologies have many dedicated communities that are a better fit for it.
- Entertainment is too many layers removed from technology. While sometimes it can fit here, business or cultural aspects of it are a better fit for dedicated communities.
- Cybersecurity. While it heavily focuses on technology, most of the time it's too technical for most people who are not already invested in it. Should be posted in a dedicated communities unless it has broader connection to other tech areas.
Post guidelines
Title format
Post title should mirror the news source title. If you don't like the title of article, look for an alternative source instead of editorializing it.
URL format
Post URL should be the original link to the article (even if paywalled) and archived copies left in the body. It allows avoiding duplicate posts when cross-posting.
[Opinion] prefix
Opinion (op-ed) articles must use [Opinion] prefix before the title. Opinion articles refer to articles that their publisher doesn't explictly endorse.
Country prefix
Country prefix can be added to the title with a separator (|, :, etc.) if the news is from a local publisher who doesn't clearly mention the country.
Rules
1. English only
Title and associated content has to be in English.
2. Use original link
Post URL should be the original link to the article (even if paywalled) and archived copies left in the body. It allows avoiding duplicate posts when cross-posting.
3. Respectful communication
All communication has to be respectful of differing opinions, viewpoints, and experiences.
4. Inclusivity
Everyone is welcome here regardless of age, body size, visible or invisible disability, ethnicity, sex characteristics, gender identity and expression, education, socio-economic status, nationality, personal appearance, race, caste, color, religion, or sexual identity and orientation.

In the real world you can expect panels to lose on average no more than 10% per decade. Usually it's less, somewhere around the 7-8% mark. Some manufacturers or installers give warranty for a max of 10% in the first decade. However due to natural variability of the energy produced, it would have to be pretty bad in order for anyone to notice.
The reason lifetimes of solar panels is given somewhere around 20-30 years isn't because they stop functioning after that time. It's because they simply won't perform very well after that time. It's a double edged sword, where the existing panels degrade and new panels get better. Especially if the mounting can be re-used, it becomes more and more favorable to just replace the panels. Chances are within 30 years at least one panel would have failed, in a string configuration that often means the entire string goes down. Depending on the setup that one defunct panel can be bypassed, but simply replacing all the panels makes more sense.
One of the parts I would like to see improvements in longevity is the inverters. Those are pretty expensive a lot of the time (depending on where you live they have to meet very strict specs and certification, driving up cost) and don't live as long. Typically an inverter will work for at least 10 years, but they hardly ever make it to 20 years. So an installation that runs for 25 years will probably have its inverter(s) replaced at least once.
This article doesn't state anything new, this has been the case for a very long time now.
