When the Sun Becomes Not-So-Favorable for Solar Panels

When the Sun Becomes Not-So-Favorable for Solar Panels

Global warming will start affecting the efficiency at which the solar panels generate energy. The higher the temperature, the lower the efficiency, which necessitates an alternate material to generate energy from solar power.

FREMONT, CA: Solar power is deemed to be one among the dominant renewable sources around the globe. It is a common belief that solar energy would become more intense if global temperatures rise. Contrary to popular belief, some many studies and experiments suggest otherwise.

Heat due to increased temperature is bad for the performance of the solar panels. Even thick snow covers compromise the generation rate among solar panels. A prominent study by NASA has proved via calculation, the percentage of decrease in the efficiency of solar panels as a side effect of global warming by the end of the next century.

The attention until now has been given only to the previously established link between climate change and the performance of solar panels. The calculations made on this pair are based on silicon solar panels, which are the most commonly available type of the solar panel in the market. The silicon solar panels are hypersensitive to the harsh effects of rising temperatures.

According to some scientists from MIT, by 2100, the temperatures are predicted to rise to 50 kWh in several parts of the world. As an immediate reaction to this rise in temperature, the silicon solar panels would suffer a gradual decline inefficiency, especially the energy output of about 15 kWh. In terms of percentage, the reports suggest that the overall decline in solar power output averages to 0.45 percent of a degree for every degree rise in the global temperature levels.

The number might seem small, but it is commonly misleading, as 0.45 percent of a degree is not a considerable number or the difference that would affect any change. This insignificant number can force a terminal loss of equipment of solar power systems in many countries where the temperatures rise above average. The damage due to the reaction of silicon solar panels at that circumstance would be more than significant.

Even though multiple factors weigh in the case of rising temperatures of the atmosphere, the reaction of the solar panel for the contribution made by a single source itself is intimidating and scary.

The majority of solar panels are built using silicon material. It would be ideal to be on the lookout for technologies that can replace the silicon in the solar panels. Recent studies have suggested that a group of materials called perovskites hold a promising feature that can be utilized to replace the silicon and make the technology cost-effective and efficient.
