Using solar energy in hydroponics involves converting sunlight into electricity through solar panels, which can be installed on the roofs of agricultural buildings or on specialized structures in the fields. The electricity generated is used to power water pumps that circulate and distribute water within the hydroponic system. Excess energy can also be stored in batteries for use at night or on cloudy days. In addition to running the pumps, solar energy is used to power LED lighting that enhances plant growth, with the ability to control the light spectrum to meet the specific needs of different plants. Solar energy also operates heating and cooling systems to maintain an optimal environment for plant growth and improves ventilation with solar-powered fans inside greenhouses or agricultural tunnels. The benefits include reduced energy costs, as the operating and maintenance costs become low once the solar panels are installed. Solar energy provides independence from the traditional electrical grid, reducing monthly utility bills. Environmentally, solar energy helps to reduce carbon emissions and conserve natural resources, minimizing the environmental footprint of hydroponics. Furthermore, solar energy improves the continuity of agricultural operations, increasing the productivity and quality of crops.
