Solar panels that grow crops directly under them have a longer lifespan

In order to generate solar power using solar panels, it is necessary to cut down the surrounding trees and collect as much light as possible to the solar panels. However, it is also true that there are concerns that such actions will have a negative impact on the environment. An alternative plan of `` growing crops under the solar panel '' that may improve such disadvantages has been devised. The researchers who conducted the study reported that 'there are benefits not only for the environment, but also for the solar panels.'

If you install a solar panel, all of the land will be taken away by the solar panel, which may be a disadvantage in terms of land utilization and environmental impact. People involved in solar panel development and agricultural systems have devised a method called ' Agrivoltaics ' that parallels solar power generation and agriculture, and continue to try to produce energy and agricultural products at the same time.

Professor Max Chan, who teaches mechanical engineering at Cornell University, examined the various benefits brought by agrivoltaics, and particularly focused on the temperature data around the solar panel. When Chan et al. investigated the surface temperature of the solar panel installed 4 meters above the soybean crop, the temperature dropped by up to 10 degrees compared to the solar panel installed 50 cm above the bare soil. It was found that

There are several possible reasons for the drop in temperature, one of which is ``evapotranspiration,'' in which water evaporates from crops and soil into the air. According to Chan et al., evaporation of water from crops grown under solar panels can lower the ambient temperature.

In addition, crops have a higher light reflectance than soil, so while simple soil stores heat and releases it to the surface, crops are less likely to convert solar radiation into heat. In addition, the fact that the solar panel was in a high position made it easier for the air to pass, he said.

Agrivoltaics could benefit both agriculture and photovoltaics, as higher temperatures reduce the life and efficiency of solar panels, according to Chan et al.

On the other hand, there is a disadvantage that the crop yield will decrease because the solar panel blocks sunlight. In order to solve these problems, prior research is also being conducted to improve the light gathering power by making the solar panel translucent.

Mr. Chan said, 'So far, solar panels have been made for the purpose of maximizing only the amount of energy production in a given area of land. , is moving to more ecologically and environmentally friendly methods.There is an urgent need to introduce renewable energy wherever possible to combat the impacts of climate change, while at the same time conserving agricultural land for food. is also important,' he said.
