How long do solar panels last? Useful life



Within renewable energies, solar is one of the most used today. While the installation of solar panels is becoming more and more frequent at a domestic level, the prices of the components necessary for it are decreasing, although it is important to note that not all of them will last us for life. Solar panels wear out over time, but what is their lifespan?

The installation of solar panels and solar energy take advantage of the sun’s energy to convert it into electricity and thus achieve a self-consumption that, in addition to saving on our electricity bill in the short and long term, allows us to achieve a consumption that has less impact on the environment. A green, clean and renewable energy that is committed to the future and that is already the option chosen by countless companies and individuals. As we well know, betting on photovoltaic installations always provides a long-term profitability and requires a significant initial investment. That is why, as with any other high-value asset, we wonder what the useful life of a solar panel is.

20 or 25 year warranty

Batteries, like solar panels, have a certain useful life and we will have to change them from time to time. Time also passes for photovoltaic solar panels, which wear out and suffer a performance drop little by little. It is obvious, but the quality of it will also determine its useful life. The vast majority have a warranty of 20 or 25 years, however, the average lifespan can be extended to 40 years.

To keep in mind is that, over time, solar panels will gradually lose their performance. Generally, this happens within the warranty period in which the manufacturer guarantees a efficiency around 85% compared to the initial. Once the 20 or 25 year warranty has passed, the performance of the panel will continue to decline. Another factor that influences the useful life of a solar panel is the material with which it is made. In relation to this aspect, it has been shown that The panels that have the longest useful life and resistance are the monocrystalline and polycrystalline ones.

The nominal power of the panels, both monocrystalline and polycrystalline, degrades around 0.5% per year, taking into account that those with a thinner film lose their qualities faster. In addition, we must also control the useful life of other components that complete the operation such as batteries and inverters. Whether a solar panel is more or less efficient will also depend on the orientation in which it is placed.

How to extend the life of a solar panel

In order to fully amortize the investment made in the installation of solar panels, it is advisable to follow some maintenance tips that can be decisive in extending the useful life of solar panels and maintaining their performance in optimal conditions for longer. The main enemy of solar panels are environmental factors. The surface can be easily covered by dust, leaves and polluting particles, so rainy days, even if the sun is scarce, are good for the maintenance and durability of the solar panels. A dirty solar panel only loses 10% of its performance, but if we do not clean it, we will be losing our investment and shortening its useful life.

Therefore, it is important to periodically clean the panels. We can do it ourselves or, what is more advisable, go to a specialized company that performs cleaning and maintenance with guarantees. After checking the status of the panels, they will be able to give us advice based on their review and status. If we decide to do the cleaning ourselves, the best times of the day to do it are in the morning or in the evening at sunset, moments in which their performance is lower compared to other hours of the day. After cleaning them with a brush and removing any elements that may have deposited, they should be cleaned with soap and water.

An important aspect to keep in mind is that the Water with which we clean the solar panels it must be warm in order to avoid damage caused by the thermal contrast if we choose to use either very cold or very hot water. Power is also important, as too strong a jet of water can damage the surface of the solar panels.

This could be the next great Motorola flagship, according to leaks



The new year has only just begun, and previews of what we could bring to see throughout it are already arriving. In this sense, the publication TechnikNews has found evidence of what could become Motorola’s “next-generation” flagship, codenamed “Frontier”, pointing to some pretty high specs.

And it is that, among other aspects, it indicates that it would carry an improved version of the current Snapdragon 8 Gen 1 SoC, which may be called Snapdragon 8 Gen 1 Plus, which has not been presented at the moment.

A high end above normal

In this regard, reference has been made to a hardware element with the code name “SM8475”, for now non-existent, taking into account that the current Snapdragon SoC, commercially known as Snapdragon 8 Gen 1, uses the code name “SM8450 », suggesting that the upward variation of the last two digits would point to a Plus version, although for now it would be speculation.

Snapdragon usually presents an improved version of the version of its SoC presented in December in the middle of the year, although with the recent change in the name of mobile processors we do not know if it will maintain this custom despite this.

In addition, in the leaked specifications there is also talk of a 6.67-inch curved FullHD+ OLED screen, which would have a 144Hz refresh rate.

This future model, let’s not forget that it is a first leak, It would also stand out for having a main camera with a 200MP Samsung HP1 sensor, accompanied by a 50MP ultra-wide-angle camera and a 12MP Sony IMX664 sensor telephoto camera.

The front camera is said to have a 60MP sensor from OmniVision, also having the Always on function of Qualcomm.

It also surprises with fast battery charging speeds, with up to 125W wired charging and 50W wireless fast charging.

The combination of RAM and internal storage will continue to be the most common at the moment, with a combination between 8GB and 12GB of RAM, and 128GB and 256GB of internal storage.

At the moment, the rest of the specifications of this future model are unknown, although with the data provided in the leak, everything suggests that it could take months to officially know this new device, so it would be enough to wait until after the summer, at least .

This Telegram feature allows you to store unlimited files online



Highly appreciated by Internet users for the transfer of unlimited files, the Telegram application receives a new very practical service. Developers have used an end-to-end encrypted messaging app API to create an unlimited cloud storage service. Good news for people who want to keep documents and files for free.

A cloud storage service on Telegram

TeleDrive developers are innovating with a very interesting new service. They relied on the API available on Telegram to develop a free cloud storage system. You can then use it to store files much like on Google One or OneDrive. To use it, simply link your Telegram account and associate it with TeleDrive to start downloads.

However, note that this service has some limitations. In free mode, the user is limited to 1.5 GB bandwidth and daily 2 GB downloads. However, it is possible to remove this restriction by subscribing to a $10/year subscription with TeleDrive. You will be able to download large volumes of files no matter the time of day.

The peculiarities of Telegram’s cloud storage

Telegram is an end-to-end encrypted instant messaging application. In view of this, the files stored on TeleDrive are of a confidential nature. That said, note that it is possible to make them public and share it by message to your contacts on Telegram. You can generate a URL that anyone on the internet can easily access.

The use of this cloud storage service, however, poses a big concern. TeleDrive has not established any collaboration with the administration that governs the operation of Telegram. At any time, the latter could therefore decide to eliminate this service. It just needs to limit or break its API from its cloud storage. It is for this reason that specialists recommend using it as a secondary backup solution.

The Tesla Cybertruck electric pickup truck will have a “little brother” in miniature form



While Elon Musk and Tesla continue to push back the start of production of the Cybertruck electric pickup truck to ever later dates, information has appeared on the network about the possible release of another version of this car.

The Tesla Cybertruck electric pickup truck will have a

Initially, the rather well-known Indian analyst Trip Chowdhry from Global Equities Research, who specializes, among other things, in Tesla, shared the information.

According to the source, Tesla will present two versions of the Cybertruck at a special event in March 2022.

Moreover, Chaudhry notes that both versions will receive “significant changes” compared to the Cybertruck originally shown. Chaudhry did not go into details of the changes, but noted that the second version of the Cybertruck will be about 15-20 percent smaller than the first. The bodies of both cars will reportedly be built by the same Texas-based Steel Dynamics company, which operates about 100 miles from Tesla’s Texas plant.

Chaudhry expects to hear the first official news on the matter on January 26, when Tesla will report earnings to investors.

Recall that in November 2019, Elon Musk himself said that in the long run it makes sense to add a more miniature Cybertruck to the lineup. Since then, however, he has not further developed the idea publicly.
