Who we are
Surya Day Pvt. Ltd. is a Delhi-based Solar EPC (Engineering, Procurement and Construction) and I&C (Installation and Commissioning) company — one of the fastest-growing names in India's renewable energy sector. Since 2014 we've built an in-house team of engineers who've designed, procured and installed over 30 MW of solar capacity across India, in projects ranging from 10 kW rooftop systems for schools to 10 MW ground-mounted plants for public sector giants.
That decade of hands-on EPC experience is what lets us size your home system correctly the first time, get your PM Surya Ghar Yojana subsidy paperwork approved without delays, and stand behind the installation long after commissioning — rather than subcontracting the job out and disappearing.
- 15+ years average experience across our core engineering team
- 100% accident-free project completion record
- In-house design, procurement, installation and O&M — nothing subcontracted out
- 10 kW to 10 MW — rooftop, ground-mounted, on-grid, off-grid and hybrid systems
