Orb Energy is a vertically integrated solar energy company headquartered in Bengaluru, India, founded in 2006 by Damian Miller and NP Ramesh, both former Shell Solar executives. The company controls the full solar value chain, manufacturing its own solar panels and solar water heaters, and handling system design, installation, financing, and after-sales service in-house.
Orb Energy’s core customer focus is small and medium-sized enterprises, a segment it identifies as underserved in India’s transition to renewable energy, alongside residential, larger commercial, and industrial clients. The company has been recognized among India’s top three rooftop solar providers according to JMK Research’s annual industry report card.
The company operates a solar panel manufacturing facility in Bengaluru, producing monocrystalline and N-type TOPCon modules, with technical guidance from PI Berlin, now part of the KIWA Global Group. Orb Energy expanded internationally in 2014, establishing a subsidiary in Kenya to replicate its Indian business model across the East African market.
Since its founding, the company has grown its branch network across India and secured multiple rounds of debt and equity financing, including support from the U.S. International Development Finance Corporation. In 2024, Orb Energy inaugurated a ground-mounted solar park in Arsikere, Karnataka, reflecting its expansion into utility-scale project delivery alongside its core rooftop business.
Orb Energy’s core business, manufacturing and deploying solar photovoltaic and solar thermal systems, directly advances SDG 7 by expanding access to affordable, clean electricity for homes and businesses. Its collateral-free, in-house financing model lowers the upfront cost barrier that typically prevents SMEs from adopting renewable energy, extending clean power access to a segment that conventional lenders often underserve.
By displacing grid electricity generated from fossil fuels with onsite solar generation, the company’s installations contribute to SDG 13 through avoided carbon emissions across its residential, commercial, and industrial customer base. The company’s operations also support SDG 8, since its branch network, manufacturing facility, and installation teams create direct employment, while its financing facility helps SME customers reduce operating costs and reinvest in business growth, supporting broader economic activity in the markets it serves.
Orb Energy operates a vertically integrated business model spanning manufacturing, engineering, installation, and financing. Its solar panels and solar water heating systems are produced in-house at its Bengaluru manufacturing facility, which uses European processing equipment and technical guidance from PI Berlin, now part of the KIWA Global Group, to support its monocrystalline and N-type TOPCon module production.
For system delivery, Orb Energy’s technical teams design rooftop and ground-mounted installations tailored to a customer’s roof structure, load capacity, and energy needs, rather than deploying standardized configurations. Installed systems are paired with remote monitoring capability, allowing customers to track generation performance after commissioning.
A central part of the company’s methodology is its in-house financing facility, introduced to address the collateral and credit-access barriers that commonly prevent SMEs from adopting solar power. Rather than referring customers to third-party lenders, Orb Energy underwrites and services solar loans directly, structuring repayment terms to align with a system’s typical three-to-four-year payback period for commercial and industrial customers.
This combination of in-house manufacturing, technical installation capacity, and direct financing is intended to give the company control over quality, cost, and customer experience across the full project lifecycle, from initial system design through long-term after-sales support.
Orb Energy positions itself within India’s rooftop and ground-mounted solar market, with a primary focus on small and medium-sized enterprises alongside residential, larger commercial, and industrial customers. The company differentiates itself through vertical integration, combining in-house panel manufacturing, installation, and financing under one provider, rather than outsourcing components of the value chain to third parties.
Its collateral-free financing facility is a distinguishing feature relative to solar providers that rely on external lenders, directly targeting SMEs that often struggle to secure long-term financing for capital equipment. Independent industry analysis places Orb Energy among India’s top three rooftop solar companies by deployment, reflecting an established position in a market that includes numerous regional and national competitors.
Orb Energy represents a distinctive model within India’s rooftop solar market: a manufacturer that also underwrites its own customer financing. This vertical integration addresses two connected barriers to SME solar adoption in India, namely inconsistent equipment quality from fragmented supply chains and limited access to collateral-free credit, by consolidating manufacturing, installation, and financing under a single provider.
The company’s twenty-year operating history, its recognized position among India’s top three rooftop solar providers, and its track record of securing follow-on financing from a development finance institution suggest a degree of operational maturity relative to newer entrants in the space. Its expansion into Kenya extends this financing-led model to a second underserved market, and its move into ground-mounted utility-scale projects indicates a broadening beyond its original rooftop-only focus.
At the same time, publicly available information on the company’s formal quality or environmental management certifications is limited, and reported figures such as cumulative CO2 offset and current installed capacity vary across sources and time periods, which limits the precision with which procurement teams can benchmark its claims. Orb Energy’s core proposition, that removing financing friction accelerates SME solar adoption, is a genuine and underserved market need, though buyers should independently confirm current performance data before procurement decisions.
