Commercial Solar Power Systems 5 kW+ & Solar Power Plants 0.5 MW+

What it is

A grid-connected solar system without batteries. Solar power runs your business loads during the day; any shortfall is drawn from the DISCOM grid and, where net or gross metering is allowed, surplus units are exported to the grid.

How it works

Solar panels produce DC power, a grid-tied inverter converts it to AC synchronised with the grid, and a bi-directional (net) meter records import and export. The system shuts down automatically during a grid outage for safety (anti-islanding).

Best for

Offices, shops, showrooms, schools, hospitals, hotels, cold storages and factories with steady daytime load and reliable grid supply.

Key benefits

• Lowest cost per kW of all system types – no battery bank
• Reduces daytime grid units and demand on your bill
• Minimal maintenance; long panel life
• Net/gross metering as per state DISCOM rules

What it is

A stand-alone solar system with a battery bank, independent of the electricity grid. It powers your loads from solar during the day and from stored energy at night or in cloudy weather.

How it works

Panels charge batteries through an MPPT charge controller; an off-grid inverter supplies AC power to connected loads from solar and batteries. A diesel generator can be added as backup for long cloudy spells.

Best for

Remote sites, farms, telecom and monitoring stations, construction sites, resorts and businesses where grid power is absent or highly unreliable.

Key benefits

• Power where there is no grid connection
• Cuts or replaces diesel generator running
• No dependence on DISCOM approvals for export
• Predictable, self-owned energy supply

What it is

A practical middle path: solar works with the grid and a modest battery bank that backs up only selected critical loads (lighting, computers, servers, billing counters) during power cuts.

How it works

Solar first serves loads and charges the battery; the grid fills the gap. During an outage, the inverter switches critical circuits to battery and solar. Export to grid is limited or not used, depending on the equipment and local rules.

Best for

Retail stores, clinics, banks and ATMs, coaching centres, small offices and workshops that face frequent short power cuts.

Key benefits

• Backup for essential loads without a large battery cost
• Solar savings plus outage protection
• Smaller battery bank than a full off-grid system
• Flexible – can be upgraded later

What it is

A fully integrated system combining grid connection, solar and batteries with intelligent energy management. It can export surplus power (where permitted) and also keep your business running during outages.

How it works

A hybrid inverter decides in real time whether to use solar, battery or grid, charges batteries from surplus solar, and can export to the grid through a net meter. Batteries can also be used to shave peak-hour consumption.

Best for

Hospitals, data rooms, hotels, manufacturing units, cold chains and any business where both savings and uninterrupted power matter.

Key benefits

• Savings and backup in one system
• Smart switching between solar, battery and grid
• Can support peak-load management
• Grid export where DISCOM rules allow

What it is

Large ground-mounted or big-rooftop solar plants of 0.5 MW (500 kW) and above for industries, institutions, captive consumption or sale of power, depending on the applicable state and central regulations.

How it works

Large solar arrays feed string or central inverters, power is stepped up through transformers and evacuated to the plant’s load or to the grid via a switchyard and approved connectivity. Remote monitoring (SCADA) tracks generation and faults.

Best for

Manufacturing industries, industrial parks, educational campuses, hospitals, warehouses, institutions and investors planning captive or open-access solar.

Key benefits

• Large-scale reduction in purchased grid power
• Captive / open-access options as per state policy
• Long-term clean energy asset
• Supports ESG and sustainability goals
