What are the three challenges of solar energy?

The initial cost of buying a solar system is quite high. Although solar energy can still be collected during cloudy and rainy days, the efficiency of the solar system decreases. One of the main concerns is the efficiency of solar panels, which only convert a small percentage of the available solar energy into usable energy. The reliability of solar energy is also an issue, especially in certain geographical regions.

While the overall environmental impact of solar energy is positive, especially compared to non-renewable energy sources, some environmental concerns also remain relevant. . After addressing solar energy challenges, the industry will experience unprecedented growth. Another concern is that solar energy could occupy a significant amount of land and cause land degradation or habitat loss for wildlife.

While solar PV systems can be attached to existing structures, larger utility scale PV systems may require up to 3.5 to 10 acres per megawatt and CSP installations require 4 to 16.5 acres per megawatt. However, the impact can be reduced by placing facilities in low-quality areas or along existing transport and transmission corridors. The denial of climate change remains an important issue even in mainstream politics, making it difficult to ensure full government support for solar energy. Even so, it is important for the solar industry to become independent of such government programs.

Since solar panels began to be installed more widely in the early 2000s and have a lifespan of about 25 years, the problem is likely to become increasingly common in the near future. However, as Theo Hobson, postdoctoral researcher in solar physics from the University of Liverpool, points out, it is possible to mitigate the problem with appropriate planning. In addition, the continental United States receives much more solar energy in July, the hottest month in the Northern Hemisphere, than in December or January. IRENA predicts that solar energy waste will amount to 78 million tons by 2050, and some academics have suggested that the amount could even be much higher.

Professionals in the solar industry should focus on technological advances and expanding the benefits of solar energy. The solution to this is to improve efficiency: if each panel is highly effective, fewer panels will be needed, and solar energy operations will require less space. This would also contribute to making the industry environmentally friendly, since solar generation would take up less space and manufacturing would require fewer resources. As installing solar panels increases the value of your home, it can also increase your property taxes.

Solar scientist Wim C. Sinke told Dezeen in a recent interview that the solar energy industry must adopt the circular economy to ensure that manufacturing and waste problems do not limit its potential. If used for 20 to 25 years, as their warranty suggests, solar panels can be a very clean form of energy. The downsides are that it only produces energy when the sun shines, needs a significant amount of land, and that certain solar technologies require rare materials.

However, building that infrastructure would be an enormous task, not least because it would have to go through privately owned land, explains solar designer and technologist Alex Nathanson. Solar energy may be a type of renewable energy, but its production is not carbon-free; the manufacture of solar cells is a process that consumes a lot of energy and requires finite materials. Solar energy is one of the most viable alternative energy sources, with its unlimited abundance and potential. .
