Top 3 challenges of solar technology
#1. Cost
One of the major challenges when it comes to solar cell working and technology is the cost involved in manufacturing and installation. Solar panels can be expensive. It stops homeowners from installing solar even when they’re aware of the benefits of solar.
The material cost is a significant factor in the high solar panels cost. High-quality materials like crystalline silicon are needed to make efficient solar cells. These materials can be expensive, contributing to the overall expense of solar panels.
Moreover, the process of solar cell working involves many intricate steps, such as doping, metallization, and passivation. These processes can be complex and expensive, driving up the overall cost of solar panels.
Furthermore, the research and development costs associated with improving solar cell working also contribute to the high price of solar panels. Scientists and engineers are constantly working to develop new materials and designs that can enhance the efficiency and durability of solar cells.
So, does this mean that investing in solar is not worth it? Well, absolutely not! This is an issue that requires clarification.
Yes, solar panels are a bit expensive but their prices have come down dramatically in the past decade. The ongoing efforts to improve solar cell working have made these PV cells much more efficient than they used to be.
There are two main types of silicon PV cells – polycrystalline cells and monocrystalline cells. Poly cells cost 25.5/ watt, and mono cells cost 31/ watt. Naturally, you can go for panels made up of poly cells to tackle budget issues.
In fact, the government offers financial help through subsidies to homeowners and housing societies to lower the cost further. Reputed solar installers also offer easy financing options. An investment of over a lakh today will give you free electricity for over 25 years. Hence, investing in solar is much more economical than paying electricity bills in the long run.
In a nutshell, the cost of solar cell working technology has steadily decreased due to advancements in manufacturing and economies of scale. As a result, solar energy is becoming more accessible to a broader range of consumers.
#2. Efficiency
Efficiency is another area where solar technology can be improved substantially. Currently, the polycrystalline panels have an efficiency of 16-17%. And mono panels are 19-21% efficient.
Solar panel efficiency refers to the percentage of sunlight converted into usable electricity. From the range we’ve already listed, it’s clear that there is significant room for improvement.
- A considerable amount of energy is lost during the process of solar cell working. This is due to reflection, recombination, and resistive losses. Additionally, solar cell efficiency decreases as temperatures increase.
- Solar cell working efficiency also highly depends on the angle at which sunlight strikes the panel. Solar panels must be precisely angled to capture sunlight directly to maximise efficiency.
Efforts are ongoing to improve solar cell working efficiency, with new materials and innovative technologies being developed to address these challenges. One promising area of research is the development of multi-junction solar cells, which use multiple layers of materials to capture a broader spectrum of sunlight and achieve higher efficiencies.
#3. Durability
The durability of solar panels is crucial to ensure long-term, reliable energy production. However, solar cell working technology faces several durability-related challenges:
- High winds, hail, and heavy snow
- Poor maintenance
- Poor panel quality
These conditions can reduce the life of solar panels. Did you know that branded tier-1 panels have a whopping life of 25 years? But if they’re not maintained, their efficiency keeps going down. And a PV panel working at half its efficiency is as good as a damaged panel.
Why? Because it will turn out to be a bad financial investment.
Therefore, proper maintenance is the only way to ensure that the capacity of solar panels stays the same. In fact, researchers and manufacturers are working on developing more robust solar cell materials and designs.
One promising approach is the development of flexible solar cells, which can better withstand mechanical stress. These flexible cells can be made using thin-film technology, which enables solar cells to be lightweight, bendable, and more resilient to adverse conditions.
Another strategy to enhance the durability of solar panels is by incorporating protective coatings and advanced encapsulation materials. Additionally, ongoing research aims to identify and develop new materials with superior resistance to degradation and mechanical stress, further improving the durability of solar cell working technology.
Conclusion
In conclusion, the technology of solar cell working holds immense potential. But challenges related to cost, efficiency, and durability must be overcome to harness the power of the sun fully.
As the famous environmentalist David Suzuki once said, “The race is now on between our ever-increasing technological skills and our ability to use them wisely.” By tackling these challenges, we can unlock the true potential of solar energy and pave the way for a better future.
