The capital will be used to strengthen the company’s end-to-end capabilities, expand enablement for EPC and installer partners, and scale its presence across India.Mumbai-based Aerem Solutions, a full-stack distributed solar platform, on Wednesday said it has raised $15 million in a pre-series B funding round led by SMBC Asia Rising Fund, the venture capital arm of Sumitomo Mitsui Banking Corporation.
Existing investors British International Investment, University of Tokyo Edge Capital Partners, Blume Ventures, Avaana Capital, Riverwalk Holdings and SE Ventures also participated in the round.
According to the official document, the capital will be used to strengthen the company’s end-to-end capabilities, expand enablement for EPC and installer partners, and scale its presence across India.
It added that the firm also plans to accelerate adoption among MSMEs and homeowners by improving access to financing, enhancing affordability and ensuring consistent project execution.
“We believe that Aerem’s integrated solutions across the solar energy ecosystem — including financing, marketplace platforms, and data-driven services — combined with SMBC Group’s financial capabilities, will play a pivotal role in accelerating the adoption of clean solar energy in India,” said Rajeev Kannan, Head of India Division and Managing Executive Officer, SMBC.
The company said that it aims to address key bottlenecks including fragmented installer capacity, limited access to affordable financing and lack of post-installation performance visibility.
Its platform integrates financing, procurement, design and lifecycle monitoring, aligning incentives across EPCs, lenders and end customers to reduce execution risk and improve asset performance.
“By integrating finance, design, procurement and monitoring into a single digital infrastructure, we are removing the ‘trust deficit’ that has historically fragmented the market,” said Anand Jain, Founder and CEO of Aerem Solutions.
The company has enabled over 1,200 MW of solar capacity and financed more than 2,000 solar projects across MSMEs, households and EPC partners. With the latest funding, the company plans to deepen its role in India’s distributed solar ecosystem as demand for decentralised clean energy solutions continues to grow.
