On-grid
Works with the electricity board supply and net meter.
- Biggest bill savings
- No battery to maintain
- Switches off during power cuts

Solar panel installation and maintenance systems
Plan rooftop solar around usable roof area, shading, sanctioned load, consumption profile, structure, electrical protection and the required grid or backup architecture.
How rooftop solar works
From sunlight to savings in four steps
Panels make power during the day, the inverter makes it usable, and any extra is stored in batteries or exported to the grid.
- 1. Panels capture sunlightRooftop modules turn daylight into DC power.
- 2. Inverter converts itDC becomes AC power for fans, lights and appliances.
- 3. Your home uses it firstDaytime load runs on solar, cutting your bill.
- 4. Extra is stored or exportedCharges batteries or earns credit through net metering.
Choose your system
On-grid, off-grid or hybrid?
The right type depends on your power cuts, your bill and whether you want backup.
Hybrid
Grid-connected, with batteries for essential loads.
- Power during cuts
- Uses grid and solar smartly
- Higher cost than on-grid
Off-grid
Runs fully on solar and batteries.
- Farms, remote sites, sheds
- Independent of the grid
- Battery sizing is critical

Frequently asked questions
Solar installation and sizing questions
Clear answers to common planning and selection questions.
How is rooftop solar capacity calculated?
Zerolink reviews electricity consumption, daytime load, sanctioned load, usable unshaded roof area, orientation and future demand before proposing capacity.
What is the difference between on-grid, off-grid and hybrid solar?
On-grid systems work with the utility supply, off-grid systems rely on supported storage, and hybrid architectures combine selected grid and backup functions. Suitability depends on the site and operating objective.
Does Zerolink provide solar maintenance?
Yes. Maintenance scope can include inspection, cleaning planning, electrical checks, generation review, monitoring checks and corrective recommendations.
How much roof space does a solar system need?
As a rough guide, each 1 kW of panels needs about 80–100 sq ft of shade-free roof and generates around 4 units a day in this region. The site survey confirms the exact figure.
Will on-grid solar work during a power cut?
No. For safety, an on-grid inverter switches off when grid power fails. If you need power during cuts, choose a hybrid system with batteries.
