					</table><p>A recent report published by the International Institute for Sustainable Development (<a href="https://www.iisd.org/" target="_blank" rel="noopener">IISD</a>) has listed specific business models that would help India cope with the challenges of implementing agrivoltaics.</p>
<p>Firstly, IISD recommends <u><a href="https://www.mercomindia.com/agrivoltaics-solve-land-scarcity-problem-solar-installations" target="_blank" rel="noopener">agrivoltaics</a></u> jointly owned by the farmer and developer, while the second way is agrivoltaics solely owned by either party, and the third model is where the developer is the primary promoter and the farmer is the partner.</p>
<p>India has a total of 14,636.6 kW of installed agrivoltaics capacity that is in the pilot stages.</p>
<p>The report highlights the challenges faced by the country’s farmers and developers in availing the benefits of agrivoltaics and suggests specific models be followed.</p>
<p>According to the experts interviewed by IISD, the third model, with the developer as the primary promoter and the farmer as the partner, is best suited to the Indian context. However, it can be considered only for barren or uncultivated areas, either due to poor land productivity or state ownership of the land.</p>
<p>About 53% of the total land area in India is categorized as arid or semi-arid, while most of India’s solar power capacity is installed in similar regions with low levels of cropping intensity, indicating complete or partial land uncultivability.</p>
<p>Arid and semi-arid regions, along with peri-urban areas, are the most favorable geographies for agrivoltaics in India.</p>
<p>However, the report says these locations have to be closer to cities and towns with proximity to markets for high-value horticultural products, for successful agrivoltaics implementation.</p>
<p><strong>Land-use &amp; Tariff Regulations</strong></p>
<p>The IISD report suggests that state governments introduce land-use regulations and classify the income from agricultural lands to recognize the full impact of agrivoltaics.</p>
<p>States must define clear standards for agrivoltaics to ensure project developers, governments, and lending institutions have a shared understanding of the criteria defining such projects.</p>
<p>Beyond the uniform ceiling tariff, the states must explore different market mechanisms to support agrivoltaics through creative tariff structures.</p>

<p><strong>Technology &amp; Other Factors</strong></p>
<p>The report finds that while technological innovations like sun-tracking systems yielded promising results in agrivoltaics in the countries like China, Japan, and Germany, such tools are not included in conventional solar plants in India, given their high cost.</p>
<p>The report recommends the use of bifacial solar panels in Indian agrivoltaic pilots as they help reduce shading effects, increase power generation, and expand crop choices that are currently limited to a few in the country.</p>
<p>IISD also points to some promising solutions, like integrating rainwater harvesting structures with agrivoltaics. However, scaling up these solutions would need further research and peer learning, given the weather conditions in India.</p>
<p>While battery storage is one of the options to store the energy for later use, not all farmers can afford it, so IISD suggests there should be an alternative to this technology</p>
<p>Most agrivoltaic pilots announced under Pradhan Mantri Kisan Urja Suraksha evam Utthaan Mahabhiyan (PM-KUSUM) program in India are yet to begin growing mainstream crops like paddy and wheat. Paddy, wheat, and sugarcane account for over 40% of India’s gross cropped area.</p>
<p>The length of such crops that are the staple food in the Indian context reaches a certain height, so it becomes critical to plan the solar PV placement in such a way that power and crop production are not hindered.</p>
<p>The report also recommends considering the open-access way through which developers can sell the power directly from agrivoltaic projects to consumers at a mutually decided price.</p>
<p><strong>Agrivoltaics in Industrialized Countries and India</strong></p>
<p>China has been actively encouraging agrivoltaics by promoting the technology through PV poverty alleviation and power generation front-runner base programs.</p>
<p>Germany, France, and Japan are constantly updating the designs and standards to use the land for accommodating solar PV with agriculture, given the fluctuating weather conditions.</p>
<p>Agrivoltaics is an emerging area of innovation that industrialized countries like China, Japan, and Germany are pursuing to use land parcels for growing crops using the power generated from solar photovoltaics.</p>
<p>The three countries combined have a cumulative installed agrivoltaics capacity of approximately 2.5 GW, while <a href="https://www.mercomindia.com/italy-greenlights-agrivoltaic-projects" target="_blank" rel="noopener">Italy</a> and France have advanced investments to implement agrivoltaics.</p>
<p>IISD pointed out that in the above countries, it was realized that integrating agrivoltaics with closed farming systems like greenhouses and conventional open farming systems was beneficial, given the diverse design options that change per the agriculture activity and weather.</p>
<p>IISD recommends that grid-connected agrivoltaics systems are likely more scalable than off-grid systems because the power produced is typically much higher than the demand within the system.</p>
<p>But, grid-connected renewable energy also requires adequate evacuation capacity and needs to be situated near substations to reduce losses. This area is yet to be explored in Indian agrivoltaics.</p>

					</table><p>Researchers at the <a href="https://www.modares.ac.ir/" target="_blank" rel="noopener">Tarbiat Modares University</a> in Iran have found that concentrator photovoltaics (CPV) helps in shading management while equally distributing the solar spectrum to balance energy and water levels in crops.</p>
<p>The work published in the journal <a href="https://www.sciencedirect.com/journal/applied-energy" target="_blank" rel="noopener">Applied Energy</a> highlights that the balanced distribution of sunlight using CPV allows photovoltaic systems to generate sufficient amounts of electricity without affecting agricultural production.</p>
<p>They claimed that solar thermal collectors can be used to convert solar energy into heat, while photovoltaics can be used to convert solar radiation directly into electricity. The researchers used CPV and mitigated the issue of shading.</p>
<p>CPV is a clean technology that offers enhanced spectral processing capabilities and comes with highly concentrated power-generating efficiency, making the technology a suitable solution for integrating photosynthesis.</p>
<p>The researchers in the new work observed the working principles of CPV modules and studied their uses in concentrating <a href="https://www.mercomindia.com/agrivoltaics-solve-land-scarcity-problem-solar-installations" target="_blank" rel="noopener">agrivoltaics</a>.</p>
<p>The researchers used parabolic glass covered with a multilayer dichroic polymer film that reflected near-infrared (NIR) radiation onto the solar cells installed at the focal area, which helped transmit photons in the range of photosynthetically active radiation.</p>
<p>The scientists then used Fresnel lenses, highly transparent sun-tracking louvers that help concentrate direct sunlight onto the solar cells to generate electricity.</p>
<p>While crops or plants do not require the complete solar spectrum to grow, combining photovoltaics to the process maintains the amount of energy and water level required for the growth.</p>
<p>However, the researchers stated that the development and use of CPV technology are slower due to relatability issues, high installation costs, lack of data and field expertise, and crucial inputs on maintenance and operating costs.</p>
<p>The team further claimed that developing photovoltaics for use in agriculture can further eliminate the dependence of farmers on fossil fuels and contribute to the reduction in greenhouse gas emissions globally.</p>
<p>In a similar study, material scientists at the UCLA Samueli School of Engineering <a href="https://www.mercomindia.com/roof-organic-solar-cells-greenhouse" target="_blank" rel="noopener">designed</a> a solar roof with semi-transparent solar cells for a miniature greenhouse prototype. They found that the solar roof helped produce sufficient energy from sunlight to grow plants or crops.</p>
<p>A team of researchers from Cornell University <a href="https://www.mercomindia.com/researchers-find-crops-improves-panel-efficiency" target="_blank" rel="noopener">found</a> that growing commercial crops on solar farms is an efficient use of agricultural land, which can boost both commercial food production and improve the performance and longevity of solar panels.</p>
