Energy storage and backup generators are frequently used in these microgrids to guarantee a steady electricity supply. They are instrumental in areas vulnerable to disasters, as they may support relief operations and supply vital electricity during catastrophes.
3. Agrivoltaics
Agrivoltaics, often known as agrisolar, is the practice of simultaneously using land for agricultural and solar power generation. This creative method maximizes land utilization by putting solar panels overgrazing or farming regions, giving farmers extra revenue streams.
According to research, some crops can profit from the partial shade solar panels create, lowering water evaporation and shielding plants from scorching temperatures. Additionally, agrivoltaics encourage the coexistence of food and energy production and lessen problems arising from land use.
4. Floating Solar Farms
Installing solar panels on bodies of water, such as reservoirs, lakes, and even seas, is known as floating solar farms or floatovoltaics. This trend is becoming more popular in areas with a high population density and limited land availability.
Reduced land use, higher energy generation from the cooling effect of water, and less water evaporation from reservoirs are just a few advantages of floating solar farms. Additionally, they can be combined with already-existing hydroelectric facilities to offer an additional energy source.
5. Solar-Powered Desalination
Producing drinkable water by solar-powered desalination is becoming viable as freshwater scarcity becomes a primary global concern. Although conventional desalination methods require a lot of energy, they can have a significant adverse environmental impact when combined with solar energy.
The efficiency of desalination systems is increasing because of advancements in solar thermal and photovoltaic technology, which increases their viability for broad use. In desert areas with plenty of sunshine, solar-powered desalination can produce clean water for industrial, agricultural, and drinking purposes.
