An on-grid (grid-tied) solar system is the most cost-effective way to reduce electricity bills in Pakistan. It connects directly with WAPDA/LESCO/K-Electric and allows you to use solar energy during the day while exporting surplus units to the national grid through net metering.
If you are searching for how to install an on-grid or grid-tied solar system, this guide explains the entire process – from planning and installation to testing and net-meter activation – written in a clear, practical, and local context.

What is an On-Grid (Grid-Tied) Solar System?
An on-grid solar system includes;
- Solar panels
- Grid-tied inverter
- Mounting structure
- AC/DC protection devices
- Bi-directional (net) meter
Immediate Benefits;
✔ No batteries required
✔ Lowest cost per kW
✔ Best ROI through net metering
However, this system works only when the grid is available and is ideal for areas with stable electricity supply.
Who Should Install an On-Grid Solar System in Pakistan?
On-grid systems are best for;
✔ Homes with daytime electricity usage
✔ Commercial buildings and offices
✔ Factories and warehouses
✔ Schools, hospitals & plazas
✔ Users aiming for fast payback
✔ Properties eligible for net metering
Requirements Before Installing a Grid-Tied Solar System
Before installation, the installer need to ensure:
- Roof ownership documents
- 3-phase electricity meter (recommended)
- Valid CNIC & electricity bill
- Shadow-free rooftop space
- Proper load calculation
- Grid compliance design

How to Install an On-Grid Solar System? Step-By-Step Guide
Installing a grid-tied solar system in Pakistan is not as complicated as the hybrid one.
The system works on the basis of direct grid connection with a green meter installed to record the units flow either consumed or exported.
We must recommend hiring a professional solar installation service provider to save your investment for a long time in a meaningful way.
Below is a step by step guide on how to install an on-grid solar system more efficiently and effectively.
Step 1: Site Survey and Solar Feasibility
Professional engineers inspect the site prior to making any conclusion for system requirements;
- Roof orientation (south-facing preferred)
- Available shadow-free area
- Structure strength
- Daily electricity consumption
- Grid voltage and phase
This ensures correct system sizing and smooth net-meter approval.
Step 2: System Design and Load Matching
Designing includes;
- Panel quantity & wattage selection
- Inverter capacity matching
- String design (voltage & current limits)
- Net-metering compliance
- Protection & earthing layout
A well-designed system avoids energy losses and inverter tripping.
Step 3: Mounting Structure Installation
The mounted structure is installed first;
- Hot-dip galvanized steel or aluminum frames
- Elevated or flat-roof structures
- 20–30° tilt optimized for Pakistan
- Chemical anchors for wind resistance
- Anti-rust coating
Structure quality directly affects panel lifespan and safety.
Step 4: Solar Panel Installation
Panels are installed with;
- Proper alignment & spacing
- Certified clamps and fasteners
- UV-resistant DC wiring
- Waterproof MC4 connectors
Panels are connected in series strings according to inverter voltage limits.
The solar panel installation is one of the underrated tasks in Pakistan as it can cause significant drop in production if installed unwisely.
Step 5: Grid-Tied Inverter Installation
The inverter is installed near the main distribution board;
- Clean wall mounting
- Heat-protected location
- DC isolators & surge protection
- AC breakers & protection relays
- Earthing & lightning arrestors
The inverter synchronizes solar power with grid frequency.
Step 6: AC and DC Wiring Integration
This step includes the integration of ac and dc wiring with the inverter;
- Panels → inverter DC wiring
- Inverter → main DB AC wiring
- Earth rod installation
- SPD and MCB installation
- Grid isolation compliance
Correct wiring ensures safety, efficiency, and grid approval.
Step 7: System Testing and Commissioning
Engineers perform;
- Voltage and polarity checks
- Inverter startup & configuration
- String performance testing
- Grid synchronization test
- Safety and shutdown testing
System output is monitored to confirm expected performance.
Net Metering Process After Installation
Net metering allows you to export excess solar units.
The process includes
- Application submission
- Utility inspection (LESCO/K-Electric)
- Approval & meter replacement
- Net meter installation
- System activation
📌 Premier Solar Solutions manages the entire net-metering process.
Common Mistakes to Avoid in Grid-Tied Installation
❌ Undersized inverter
❌ Poor earthing
❌ Shadow-affected panels
❌ Non-approved inverter brands
❌ Wrong string configuration
❌ Unsafe wiring
These issues can delay net-meter approval or damage the system.
Advantages of On-Grid Solar Systems
✔ Lowest installation cost
✔ Fast return on investment
✔ Reduced electricity bills
✔ Environment-friendly
✔ Scalable for future expansion
✔ No battery maintenance
Limitations of Grid-Tied Solar Systems
⚠ No backup during load shedding
⚠ Depends on grid availability
For backup needs, hybrid systems are recommended.
