Gurugram Commercial Rooftop Installation
A net-metered rooftop system on a commercial office building, offsetting daytime HVAC and lighting loads.
Overview
On-grid, hybrid and off-grid rooftop solar for homes, commercial buildings and industrial sheds, designed for maximum yield and clean integration.
Rooftop solar converts unused roof area into a generating asset that offsets grid consumption for decades. ARK delivers residential, commercial and industrial rooftop systems as complete projects, from structural assessment and yield simulation to net-metering support and post-installation monitoring.
Every roof is different. We design mounting for RCC slabs, metal sheet roofs and tin sheds, with wind-load calculations for the site and clean cable routing that respects the building. Inverters are selected for the load profile, with string monitoring so performance is visible from a phone.
Systems can be on-grid with net metering, hybrid with battery backup for outages, or fully off-grid for locations without supply. Where applicable, we prepare and file the documentation required for utility approvals on your behalf.

Monitoring included
App and web dashboards for generation, consumption and alerts.
Sustainability reporting
Generation data supports ESG and carbon accounting requirements.
Applications
Where it is used.
Homes and housing societies
1 kW upwards, with net metering and optional battery backup.
Commercial buildings
Offices, retail, hotels and hospitals with daytime load profiles.
Industrial sheds
Large metal-roof systems for factories and warehouses.
Educational campuses
Schools and universities reducing operating cost and teaching sustainability.
Cold storage and agro-processing

How it works
From sunlight to output.
- 01
Modules generate DC
Rooftop modules convert sunlight into DC power throughout the day.
- 02
Inverter converts to AC
String or hybrid inverters convert DC to grid-quality AC power.
- 03
Loads are served first
Solar power feeds building loads directly, reducing grid draw.
- 04
Surplus exported or stored
Excess energy is exported through a net meter or stored in batteries.

FAQs
Common questions.
Not answered here? Ask our engineers.
How much roof area is needed?
As a rule of thumb, around 8 to 10 square metres per kW for modern high-efficiency modules, depending on tilt and layout. We confirm this during the roof survey.
What is net metering?
A bi-directional meter records both import and export. Surplus solar exported to the grid is credited against consumption according to the applicable state policy.
Will solar work during a power cut?
Standard on-grid systems shut down during outages for safety. Hybrid systems with batteries continue to supply designated loads.
How long does installation take?
Residential systems are typically installed in a few days; larger commercial systems take longer and are scheduled around site operations. Utility approvals can add time depending on the DISCOM.
What about maintenance?
Rooftop systems need periodic cleaning and an annual inspection. Our O&M plans cover cleaning, monitoring and warranty coordination.
