Solar Appreciation Day 2022: Here’re Some Unique Use of Solar Technologies Worldwide to Combat Energy Crisis
India’s budget for FY2022-23 clearly highlights the country’s priority to double down for ‘green’ and renewable energy, particularly solar, to combat climate change and meet the emission reduction targets set for 2030.
Moreover, as the Ukraine-Russia war continues, coal and natural gas prices are surging sharply across the globe. With the soaring power bills, several European and Asian countries are seeking alternatives to Russian supplies. And using technologies based on solar energy is a comparative quick fix to the energy crisis.
Meanwhile, Solar Appreciation Day 2022 is here, which is celebrated globally on every second Friday of March. The day has become all the more significant amid the ongoing climate and energy crisis. On this day, here are some unique solar technologies that demonstrate the immense potential of solar technologies to address the needs of the modern world.
Solar trolley invented by a farmer from Haryana
Pradeep Kumar, a farmer from Haryana, has built a mobile solar plant with panels mounted on a trolley that can be moved on demand. The trolley is custom made as per the user’s requirements.
In an interview with The Better India, Pradeep said, “the devices come in two sizes and carry solar panels which provide electricity of 2 HP and 10 HP. The trolley can also be mounted to the back of a tractor and has sturdy wheels that allow it to move over uneven surfaces.”
The cost-effective technology has benefitted over 2000 farmers so far.
Bihar’s floating solar power plant
The Mithila region in North Bihar is called the ‘Land of Ponds’ and is taking complete advantage of its gift. A floating solar plant is set to be commissioned in the region, consisting of 4,004 solar modules. Each module lodged in a pond can generate 505-megawatt peak (MWp) electricity and nearly 2 MW of green and clean energy. The plant can supply electricity to 10,000 people in the state.
The main benefit of a floating solar power plant is that the water cools the solar panels, ensuring their efficiency when temperatures rise, resulting in increased power generation. It also minimises evoporation of freshwater and aids fishery.
This innovation has hit two birds with one stone: producing green energy from solar panels and promoting fish farming underwater.
South Korea’s solar shade
In South Korea, a highway runs between Daejon and Sejong and its entire bike lane on the 32 km stretch is covered with solar roof panels. Not only do they generate sufficient electricity, but they also isolate cyclists from traffic and protect them from the sun.
The two-way bike lane is constructed right in the middle of the road, while there are three other lanes for vehicles to travel on either side. This also obstructs the high beam lights of oncoming cars.
Using the technology, the country can intern produce clean, renewable energy.
Solar-powered desalination technique by Chinese and American researchers
Desalination process is considered to be among the most energy-intensive activities. Now researchers have developed a solar desalination process that can treat contaminated water and generate steam for sterilizing medical instruments without requiring any power source other than sunlight itself.
The design includes a dark material that absorbs the sun’s heat and a thin water layer above a perforated material that sits atop a deep reservoir of salty water such as a tank or a pond. The holes allow for a natural convective circulation between the warmer upper layer of water and the colder reservoir below and draw the salt from the water.
Not only is the solar-powered desalination method efficient but also highly cost-effective.
Saudi Arabia’s goal of sustainable development using solar technology
Dry-climate arid regions are prone to droughts and often face water scarcity. While local food production would have been a distant dream for countries that host mostly deserts, scientists in Saudi Arabia have developed a unique solution using solar technology.
In an experiment, they designed a solar-driven system that could successfully cultivate spinach using water drawn from the air while producing electricity. This proof-of-concept design has demonstrated a sustainable, low-cost strategy to improve food and water security for people living in dry-climate regions.
“Our goal is to create an integrated system of clean energy, water, and food production, especially the water-creation part in our design, which sets us apart from current agrophotovoltaics,” says senior researcher Peng Wang.
