EPC
Engineering, Procurement & Construction — handled by one accountable team.
A single accountable partner, from paperwork to power-on
Many solar 'installers' only bolt on panels. We run the full EPC lifecycle so your project doesn't stall between vendors.
End-to-End EPC
One accountable team for design, procurement, installation, and commissioning — no finger-pointing between vendors.
Engineering-First Design
Every plant is sized from your actual load and site conditions, not a generic template.
Approvals Handled
We manage DISCOM liaison, net-metering, and compliance paperwork on your behalf.
After-Commissioning Support
AMC and monitoring plans keep your plant performing at its rated output for years after handover.
From first call to full commissioning
A clear, five-step process — so you always know what's happening with your project and when.
Site Assessment
Our team studies your roof/land, load pattern, and electricity bills to size a plant that matches your actual consumption.
Design & Engineering
Detailed system design covering structural, electrical, and safety compliance — shared with you before any work begins.
Approvals & Net-Metering
We handle DISCOM applications, net-metering, and statutory approvals so you don't have to chase paperwork.
Installation
Certified installation teams execute the build with strict safety and quality checkpoints at every stage.
Commissioning & O&M
Post-commissioning, we hand over a monitored, warrantied plant and stay on for ongoing maintenance support.
Built for businesses that run on serious power
If your electricity bill is a line item that matters, a Day Industries solar plant is designed to bring it down.

EPC stands for Engineering, Procurement, and Construction. Instead of sourcing modules, inverters, and installers separately, an EPC partner like Day Industries designs the system, procures every component, and installs and commissions the plant as one accountable project.
