With heat waves being reported around the world, causing wildfires and other environmental concerns, at least one energy sector is getting attention for its major production potential: solar power. But because solar panels harvest energy from the sun’s radiation, global warming may (unexpectedly) have little benefit to solar energy production. However, this does not stop consumer interest from increasing as people are encouraged to invest in solar technology due to hotter summers and rising consumer prices. With many parts of the world having some of the hottest summers on record in decades, it must be doing wonders for solar power, right? As the world warms, people may think that more sun will mean more solar energy, even though it has been negative for many other reasons. But rising temperatures can hamper the production of solar energy, because solar panels operate at around 25oC and become less efficient when the heat gets too high. And while the heat isn’t hindering the sun’s production, it’s doing little to help.
With record temperatures across Europe this summer, with the UK reaching 40oC in July, solar farms have seen positive output levels, with Solar Energy U.K. reporting on July 20 that the country’s solar power output was “a quarter full”. of the UK’s power demand”. But this is mainly due to the country seeing more days of sunlight rather than higher temperatures.
Of course, when there is sunshine there is solar energy. But because of the way solar panels work, they are slightly less efficient, about 0.5 percent, at any degree above or below 25oC. This means that in much of the world, peak production periods often occur in the cooler spring months rather than summer. Although Solar Energy UK believes that significant outages would only be seen if temperatures rose by 65oC or more. The company’s CEO, Chris Hewett, said: “It’s a little bit better for efficiency in the spring, but basically if you have more light, you produce more solar energy.” He added: “You have to remember that solar panels work all over the world. The same technology we put on our roofs is used in solar farms in the desert of Saudi Arabia.’
But uncertainty about what rising temperatures will mean for solar panel productivity has not stopped interest in solar power rising as the public sees a correlation between warmer weather and solar power production. As countries around the world rapidly increase consumer energy prices, utility bills are costing hundreds or thousands more people an extra year. This has helped move public opinion in favor of the rapid construction of strong renewable energy sectors, as well as the installation of home solar technology, as oil and gas see their limits.
Governments have been trying for years to stimulate public interest in solar and wind power, even by offering household tariffs, where payments are made to people who produce their own solar power to encourage the installation of solar panels at home. Governments have offered to buy solar power from grid-connected home producers and subsidized the cost of solar technology and installation in many parts of the world. And while usage has steadily increased, the recent rise in energy prices may be the factor driving consumers to make the switch on a wider scale.
In the UK, the number of searches for solar panels and solar batteries on eBay increased by 54 percent and 134 percent in June compared to the same period last year. Demand for products to track and reduce energy consumption, such as smart meters, has also increased. In 2020, a government report indicated that around 970,000 homes in the UK had solar panels, just over 3 per cent of homes, and power production had increased from 1MW in 2008 to 11,730MW in 2020. According to UK credit company Experian, around 1.9 million households are expected to install solar panels or other renewable energy technologies by 2022, showing a significant boost in public interest.
Many consumers are put off home solar energy due to the high cost of installing solar panels. But with electricity and gas bills continuing to rise in 2023 and beyond, many are seeing the potential value of the initial cost. With installations in the UK averaging between $6,000 and $18,000, households are likely to recoup the cost of the installation in less time, and halve the years it takes to pay back the money if energy bills continue to rise.
Although the heatwaves we are seeing around the world will not increase solar production as many thought, they have stimulated interest in solar technologies. As consumers see rapidly rising energy prices and warmer, sunnier days, many are now turning to renewable energy sources such as solar power as an alternative to help them save money and become more self-sufficient.
