How much do hurricanes affect solar power generation?

What is it about?

The United States of America (US) is striving hard to reach the net zero goal. This means the country needs to reduce its greenhouse gas emissions to nearly zero. To do so, the US is planning to invest more in renewable energy, including solar energy. The latter could contribute to 55% of the total power generated in the US by 2050. However, we need to know the risks of using solar power during extreme weather such as hurricanes. Hurricanes bring with them thick rain clouds that can both obstruct and reflect sunlight. Naturally, the presence of these clouds and extreme weather conditions can greatly reduce solar energy generation. But to what extent? To get a better picture, a team of researchers developed a new data driven method based on probabilities. They used it to study the risk that hurricanes posed to solar power generation across 38 central and eastern states in the US. In some states, they found that hurricanes could cause power losses of more than 66%. But thankfully, these losses are temporary. More permanent loss can occur if solar panels are damaged, though. The real danger is if these two effects occur together. Then, there can be large energy losses in regions affected by a hurricane. The authors therefore suggest the use of more resilient solar panels.

Why is it important?

In today’s world, continuous power supply is an important need. It helps keep people connected. It helps keep businesses and everyday life moving. This becomes even more important in the aftermath of a natural disaster (like a hurricane). And, with the growing usage of solar power, it has become necessary to assess the risks linked with it. KEY TAKEAWAY: Hurricanes can greatly affect solar power generation. And with the increase in global warming, such extreme weather events are only expected to become more frequent. Governments therefore need to conduct a careful risk assessment before investing in solar power and make informed choices.
