Bridging India’s ₹1 Lakh-Crore Rooftop Solar Gap: How Unisolar is Leading the Charge

India’s energy future lies not in large-scale thermal plants or grid expansion—but right above us.

Despite the country’s ambitious target of achieving 40 GW of rooftop solar capacity by 2022, installed capacity remains stuck at just 11 GW. 

This persistent shortfall represents not only an infrastructural challenge, but also a ₹1 lakh-crore opportunity waiting to be unlocked.

Unisolar Power, a venture from the Favcy 1to10 Accelerator Cohort, is emerging as a standout operator poised to address this opportunity with precision, scalability, and innovation.

A Model Designed for Scale: Solar-as-a-Service

One of the primary hurdles in rooftop solar adoption has been high upfront installation costs, lengthy regulatory procedures under schemes such as Surya Ghar, and inconsistent service infrastructure across non-metro regions.

Unisolar addresses these frictions through a BOOT (Build-Own-Operate-Transfer) model, offering:

• Zero upfront cost for customers

• Ownership, installation, and maintenance handled end-to-end by Unisolar

• A smart energy monitoring platform (launching 2025) to track output, losses, and subsidy flows in real time

This full-stack approach reduces financial and operational risk for customers while enabling Unisolar to scale its footprint with efficiency and capital discipline.

Notable Achievements

• 1000+ rooftop solar plants installed

• ₹10+ Cr in lifetime revenues with consistent YoY growth

• Secured a ₹18 Cr work order

• Sanctioned a ₹2 Cr credit line from SBI

• Partnered with leading enterprises including Amazon, BHEL, and Bollant Industries

Supported by the 1to10 Accelerator

Unisolar’s rapid progress is backed by strategic support from the 1to10 Accelerator, a flagship initiative by Favcy Venture Builders.

Through the program, Unisolar:

• Structured a ₹3 Cr fundraise for asset investment and operational expansion

• Garnered strong interest from 25+ institutional and angel investors

• Gained access to a curated network of mentors, climate-tech specialists, and distribution experts

The accelerator enabled Unisolar to sharpen its capital strategy, define a scalable operating model, and prepare for multi-state expansion with institutional rigor. The 1to10 Accelerator is currently also accepting applications for its upcoming cohort from startups building in the Climate & Sustainability space. 

India’s Clean-Tech Investment Landscape

Recent data from BloombergNEF reveals that India surpassed China in clean-tech funding in Q3 2024, with over $2.4B raised—second only to the United States. 

The momentum is clearly shifting toward climate ventures that combine asset-light models, technology-first operations, and measurable environmental impact.

Unisolar’s model fits squarely within this thesis.

As India navigates the twin challenges of energy access and sustainability, ventures like Unisolar demonstrate how innovation, when paired with the right capital and ecosystem support, can transform rooftops into revenue-generating, climate-positive assets.
