Solar panels can survive frosts, hurricanes, and even storms, but if you make them,
How is solar energy developing?
Since 1980, the price of panels has fallen 100 times.By 2023, the capacity of installations worldwide is expected to exceed1 terawatt, and by 2050 — 30-100 TW.Today, they may not live to see these years, as their quality remains in question.
To displace fossil fuels, solar power must work reliably — both in the tropics and at the North Poles.Even during storms, hail, heat and snow.Most modules have a 25 to 35 year warranty.And in the U.S., less than 1% of panels fail within the first five yearswork.
If solar panels last this long, what's the problem?
Today, solar energy systems are startingplace in different atypical places, for example, in the mountains or on the water. New cell designs, materials, and packaging technologies are also entering the market. Therefore, strength tests should also become more diverse. In addition, some components that passed quality tests 10 years ago become defective today.
Producers looking to improveenergy efficiency and cost reduction, make the modules bigger and thinner: they connect many cells together to increase power and speed up production. Supply disruptions are possible, for example, due to a pandemic, so some manufacturers use cheap, low-quality or even fake components
The operation and maintenance of low-quality equipment costs utilities tens of millions of dollars a year, all of which is wasted in electricity.Over the decades, the figure grows to billions.
How does the environment affect solar panels?
Solar panels are increasingly exposedexposure to extreme weather conditions that occur due to climate change. During a storm in Texas in 2019, hail almost 7 cm in diameter destroyed modules that power about 20,000 homes. Insured losses exceeded $75 million.
If such situations are ignored, thenthe spread of solar energy will slow down. The sector will face major insurance claims, loss of revenue, financial risks and security issues. Accordingly, corporations will begin to be suspicious of the installation of panels.
If solar panels are so easy to destroy and there is a lot of marriage on the market, maybe abandon this method of generating energy?
Scientists are confident that the technology of solar energy generation itself is incredibly promising and canFor example, when 10 million people lost power during a severe freezing wind in Texas, USA, about 111 people died and $130 billion in damage.Thermal power did not work, wind turbines had low efficiency, but solar energy production was largely unaffected.It accounts for 2% of all energy in the state.
Five steps experts have formulated to overcome the main problems of solar energy
Solar energy scientists and engineers, investors, and consumers have formulated five steps that will helpMake the solar energy sector more sustainable.
- Develop science
Laboratory tests and computer models need to be improved to evaluate the performance of next-generation panels.Researchers need to better understand the degradation process of the device.the actual climatic conditions in which it will operate.lead to erroneous results.
- Raise Quality Standards
Quality standards are widely used fortesting individual components, such as panels and diodes. But they do not apply to the entire solar system. If the device is not assembled correctly or there are differences between the components, all this can lead to a decrease in performance. Control should go beyond checking just at the factory, using random sampling and checking for compliance at every stage of the supply chain - this is how the food industry works. Standards also need to be constantly updated to reflect the latest technology.
- Track down faults
Some operators of large solar panels are alreadyuse infrared or visible cameras on drones and aircraft to track down faults. But more advanced analytical methods are needed to quickly read and interpret panel performance data. In the event of a breakdown, this will help to respond quickly and reduce production losses and damage. For these purposes, you can use a neural network: it will help in finding even the slightest flaws.
- Making the production process transparent
Rarely do manufacturers report how it wasthe panel is made, or list what it is made of. Due to supply disruptions that occurred during the pandemic, it is not always known what quality components were used to create the device. Developers, buyers, and testers should request accurate information about module content.
For example, when operators in New Jersey worked at a large facility and examined 12% of inefficient modules, it turned out that the problem occurred due to irregularities during the production process.
- Spread information
It is necessary to disseminate and implement advancedexperience in the production of solar panels around the world. For example, in regions prone to hurricanes. These are simple steps that can save lives: use strong supporting structures that can withstand storm winds, install bolt-on frames or multi-mount clamps, use vibration-resistant bolts, place mounting brackets in the rafters, not just in the roof, and do not install panel close to the edge.
All these methods that improve the quality of worksolar panels are cost effective compared to losses due to climate change. Power outages due to hurricanes in the United States cost $150 billion in 2018 alone, and flooding in Germany in 2022 cost $11.3 billion. Investing in the quality of solar panels guarantees decades of affordable and clean electricity.
