Commercial Off-Grid Solar Solutions
Commercial establishments such as offices, hospitals, malls, hotels, IT parks, and industrial facilities often operate in areas with unreliable grid power or require energy independence. Commercial off-grid solar solutions provide a self-sufficient, sustainable, and cost-effective way to meet these energy demands.
By generating electricity on-site and storing it in batteries, businesses can operate continuously without relying on the utility grid. These off-grid solar systems for commercial buildings are ideal for energy-intensive operations, remote locations, and facilities that cannot afford downtime.

Key Benefits for Businesses:
- Energy independence and uninterrupted power supply
- Reduction in operational electricity costs
- Enhanced environmental sustainability and CSR compliance
- Long-term financial savings and ROI
How Commercial Off-Grid Solar Systems Work
A commercial standalone solar system integrates solar panels, battery storage, and inverters to provide a reliable, independent power source:
Solar PV Panels: Capture sunlight and convert it into direct current (DC) electricity.
Inverter: Converts DC electricity into alternating current (AC) to power your building’s electrical systems.
Bi-Directional Meter: Measures the energy produced by your solar system and tracks how much electricity you send to and pull from the grid.
Grid Export: Excess energy generated by the solar panels is sent back to the grid, earning you revenue/credits through Gross Metering or Net Feed-in (as per state policy).
Grid Backup: Automatically pulls electricity from the grid when solar energy is insufficient, ensuring uninterrupted power supply.
