					</table><p>India’s industrial sector is increasingly adopting rooftop solar to offset rising electricity costs and improve energy efficiency within existing infrastructure constraints. Large manufacturing units, in particular, are leveraging distributed solar systems across factory rooftops to optimize available space while maintaining uninterrupted operations.</p>
<p>Chemicals manufacturer, <a title="https://www.pidilite.com/" href="https://www.pidilite.com/" target="_blank" rel="noreferrer noopener">Pidilite Industries</a>, known for products such as adhesives, sealants, and construction chemicals, has installed a rooftop solar system with a total capacity of 1,378.7 kW across its manufacturing facilities in Himachal Pradesh. The installation spans five sub-factories and 15 rooftops with varying structural conditions, orientations, and load-bearing capacities.</p>
<p>The rooftop systems were commissioned in a staggered manner from November 2025 to January 2026. Within the first three of operation, the system generated approximately 1.3 million units of electricity, resulting in savings of ₹1.41 million (~$14,995) for Pidilite.</p>
<p>The project was designed to maximize generation within the available rooftop space and capital expenditure.</p>
<p>Pidilite Industries manufactures consumer and industrial products catering to sectors like construction, woodworking, packaging, and crafts.</p>
<p>Maharashtra-based renewable energy solutions provider <a href="https://artha.energy/" target="_blank" rel="noopener">Artha Energy Resources</a> executed the project. The system uses Navitas 590 W non-DCR n-type TOPCon solar modules.</p>
<p>Artha Energy customized the system design to address multiple roof types and industrial conditions. Founder and Managing Partner Animesh Damani said, “We conducted detailed 3D shading analysis and structural stability assessments for each rooftop before finalizing the layout, thereby preventing potential leakage issues and maintaining structural integrity.”</p>
<p>The company deployed different mounting systems based on roof specifications, including non-penetrative ballasted structures for RCC roofs and specialized clamps for metal sheet roofing. This approach ensured that installations did not require drilling.</p>
<p>The system design incorporates multiple string inverters with independent maximum power point tracking. This configuration allows each section to operate independently, ensuring that lower performance in one area does not affect overall generation.</p>
<p>The modular design also enables the system to work around existing structures such as vents and chimneys without affecting performance.</p>
<p>Damani said, “Execution challenges were significant due to the facility’s operational nature. Installation activities had to be carried out without disrupting the plant’s continuous production schedule.”</p>
<p>The company said the non-penetrative design required lightweight and stable mounting solutions that could be installed without altering existing roof structures.</p>
<p>Last December, Artha Energy Resources <a href="https://www.mercomindia.com/honeywell-automation-cuts-power-costs-with-332-3-kw-rooftop-solar-system" target="_blank" rel="noopener">installed</a> a 332.30 kW rooftop solar system for Honeywell Industrial Automation at its facility in Dehradun.</p>
<p>Mercom India organizes nationwide ‘C&amp;I Clean Energy Meets’ to connect solar developers with businesses exploring clean energy adoption. These events are designed to bring key stakeholders together on a single platform and promote greater awareness of the advantages of transitioning to solar energy among commercial and industrial consumers.</p>
<p>The next event will be held in <a href="https://www.mercomindia.com/event/c-and-i-clean-energy-meet-2026-jodhpur" target="_blank" rel="noopener">Jodhpur</a> on May 15, 2026.</p>

					</table><p>Solar power adoption in India’s commercial and industrial (C&amp;I) sector is accelerating as companies seek to manage rising electricity costs, meet sustainability targets, and ensure long-term energy security.</p>
<p>One such company is <a href="https://automation.honeywell.com/us/en" target="_blank" rel="noopener">Honeywell Industrial Automation</a>, which has installed a 332.30 kW rooftop solar system at its facility in Dehradun. While the first post-solar electricity bill has not yet been generated, the company expects annual savings of ₹3.33 million (~$37,548).</p>
<p>Honeywell provides advanced solutions that help process industries operate more efficiently and safely. The company develops world-class sensor technologies, automation and control systems, and digital solutions that streamline industrial operations.</p>
<p>Honeywell’s total energy requirement at the facility is approximately 780 kW per day. Due to contractual demand limitations, the rooftop solar system capacity was capped at 332.30 kW, demonstrating the role of on-site solar in significantly offsetting grid power consumption for industrial units. The system includes Navitas 590 Wp TOPCon solar modules for this project, paired with two Sungrow 125 kW inverters.</p>
<p>Despite this restriction, the installation is expected to supply around 42.6% of the facility’s total energy needs. Honeywell’s annual energy charges are estimated at around ₹8 million (~$90,233) based on existing consumption patterns.</p>
<p>Maharashtra-based renewable energy solutions provider, <a href="https://artha.energy/" target="_blank" rel="noopener">Artha Energy Resources</a>, in partnership with <a href="https://www.blinfraprojects.in/" target="_blank" rel="noopener">Blink-Infra Projects</a>, commissioned the project on November 27, 2025.</p>
<p>Animesh Damani, the Founder and Managing Partner of Artha Energy, said, “The project faced site-specific challenges due to the hilly terrain, including the requirement for manual earthing and heightened safety considerations. We deployed additional skilled manpower and worked closely with a safety-conscious client team to ensure compliance, safety, and timely execution.”</p>
<p>The company stated that its prior experience with rooftop solar projects across diverse geographies helped it address these challenges without delay. The initial coordination issues arose from multiple stakeholders involved in the rented infrastructure, but they were resolved during commissioning.</p>
<p>Artha Energy will provide maintenance and asset management services for 25 years, ensuring the system&#8217;s long-term performance and reliability.</p>
<p>The company noted a broader surge in solar adoption across the C&amp;I sector, driven by sustainability commitments, cost pressures, and supportive government policies.</p>
<p>To raise awareness among businesses about the benefits of transitioning to solar, Mercom India has been hosting nationwide ‘C&amp;I Clean Energy Meets’ that bring solar developers and companies intending to adopt clean energy sources under one roof.</p>
<p>The next event will be held in <a href="https://www.mercomindia.com/event/c-and-i-clean-energy-meet-2026-nashik" target="_blank" rel="noopener">Nashik</a> on January 9, 2026.</p>
