Solar engineering, procurement, and construction (EPC) contractors are increasingly turning to design and simulation platforms to cut proposal delays, improve design accuracy, and connect field assessments with simulation, financial modeling, and procurement workflows.

In an exclusive interview with Mercom India, Shashank Jha and Kalyan Tarafdar, co-founders at Reslink, which provides software and hardware to accelerate clean energy projects, discuss how solar EPC software and simulation platforms help EPCs use mobile-first 3D design, simulation, proposal, compliance, and procurement integration tools to improve project execution.

How is Reslink Energy helping solar EPC companies streamline project design, proposal generation, and customer management workflows in India?

Reslink connects the entire pre-execution workflow in one place. Site assessment, 3D design, shadow analysis, energy simulation, financial modeling, and proposal generation all occur within a single platform. What previously required multiple tools, multiple people, and two to four days can now be completed on a phone in under 20 minutes.

The biggest practical change is for field sales teams. A sales rep visiting a residential site in Pune or a factory rooftop in Surat can now generate a branded 3D proposal while standing in front of the customer, answer return on investment (ROI) and payback questions in real time, and close in the first meeting. EPCs using Reslink have reported up to 30% improvement in lead conversion within the first month, largely because the proposal reaches the customer while their intent is still active.

As India’s rooftop solar market scales, how are EPC workflows evolving?

Three things are happening at the same time. Project volumes are rising faster than EPC teams are growing, so every workflow inefficiency gets amplified. A company that could manually manage 10 projects a month starts to break down at

Second, customers are more informed than they were three years ago. They expect a visual proposal, a clear generation estimate, and clarity on ROI during the first meeting, not a Portable Document Format (PDF) three days later. Third, projects are getting more complex. Ground-mount, hybrid systems, battery energy storage system (BESS) integration, time-of-day (TOD) tariff modeling for commercial and industrial (C&I) customers, all of this means the design and proposal layer has to keep pace. The EPCs adapting fastest are the ones standardizing their workflows digitally so that no single team member becomes a bottleneck.

What are the most common operational bottlenecks EPC companies face today?

The biggest one is handoff loss. A sales rep visits the site, collects measurements and photographs, hands the information to a design engineer, who prepares a layout, passes it to someone for c
