Co-Generation of Solar Electricity and Agriculture Produce by Photovoltaic and Photosynthesis—Dual Model by Abellon, India

Sustainable use of land and water is crucial in the era of climate change. Abellon Clean Energy has established 3 MW solar plant for practicing agricultural under the solar panels to address food and energy security involving a rural community. This innovation is first of its kind named as “solar-agri-electric model.” The water used for washing the solar panels to maintain efficiency by dust removal irrigates agriculture produce under the panels. This gives 24–34 tones/hectare/yr agriculture produced by reusing 78 lakhs liters of water per year and capturing 250 tons of CO₂ in vegetables as food. The 3 MW solar project is registered under clean development mechanism (CDM) under United National Framework Convention on Climate Change (UNFCCC) that reduces 0.1 million tonnes CO₂ emissions over 25 years vis-a-vis fossil fuels. Around 52 MT/yr post-harvested residues are used for organic fertilizer, composting, and fodder. Compound wall to safeguard the project site allowed creeper vegetables to grow and reduces dust deposition on the panels through wind breaking filtration. This initiative enhanced degree of sustainability along with local employment of 215 people from four villages including 156 women. In India, 1059.64 MW installed solar plants have potential to sequester 1,600,000 tons CO₂/year with abilities of 10,000 tons of agricultural produce that could employ 2000 people. Worldwide solar farms have potential to sequester 143,000 MTCO₂ through vegetation producing 100,000 MT of agriculture produce annually. Efficient use of natural resources requires facilitation of local/regional policies with reference to climatic condition, agricultural potential, and availability of natural resources.
