What is an On-Grid Solar System?
An on-grid solar system, also known as a grid-tie solar system, is a renewable energy solution that connects directly to the power grid and electricity utility service provider.
The word “Grid” means electrical power obtained from electricity provider companies such as WAPDA.
This setup helps residential , commercial and industrial setups to generate their own clean, renewable Energy with solar panels.
This solution is ideal for main city areas where there is no loadshedding of electricity. It’s very important to understand that an on-grid solar system may not completely fulfill your energy requirement. You will be dependent upon electricity providers at night to get a constant electricity supply. On-grid systems are popular in Pakistan due to their efficiency, cost-effectiveness, and compatibility with net metering policies.
Switching to an on-grid solar system is a smart investment for sustainability and financial savings. Vinova Enterprises a solar company in Islamabad offers reliable solar solutions for your energy consumption and requirements.
Key Features of On-Grid Solar Systems
- Direct Grid Connection: Operates & synchronizes in parallel with the utility grid.
- No Battery Requirement: Zero running cost.
- Net Metering Benefits: Earns credits for electricity exported to the grid.
- Easy Maintenance: It Just needs cleaning and washing of the solar panels.
How Does an On-Grid Solar System in Pakistan Work?
An On-Grid solar system operates by using sunlight to generate electricity and integrate it smoothly with the utility grid. Below is the step-by-step process:
- Solar Energy is generated using solar panels that capture sunlight and convert it into direct current (DC) electricity.
- Inverter Functionality is to convert DC electricity into alternating current (AC), making it usable for home appliances.
- Power Utilization is done by this generated electricity, which powers the household’s electrical appliances and systems.
- Excess Energy (electricity produced) is then exported to the WAPDA, where a net meter monitors the exported output and keeps the track of electricity exported and imported.
- Grid Backup: Low sunlight causes less electricity generation from solar (e.g., at night or on cloudy days) so, electricity can be used by the power grid to meet energy requirements.
Advantages of On-Grid Systems in Pakistan
- Provides a non-stop power supply when paired with a reliable grid.
- Maximizes savings through net metering.
- Environmental friendly by reducing reliance on fossil fuels.
- Reduces carbon footprint and overcomes environmental pollution.
Components of an On-Grid Solar System
An on-grid solar system is made up of several essential components that work together efficiently:
Solar Panels
These are the primary components that capture sunlight and convert it into electricity. High-quality solar panels ensure better efficiency and durability.
Solar Inverter
The inverter converts DC electricity from the solar panels into AC electricity, making it suitable for homes and businesses.
Mounting Structure
This structure supports the solar panels and ensures they are installed at the optimal angle to maximize sunlight exposure.
Net Meter
The net meter records and tracks the Energy exported to and imported from the utility grid and provides accurate billing and credits as per WAPDA and NEPRA policies.
Wiring and Connectors
High-quality AC and DC wiring and connectors are essential for efficient energy transfer and system safety.
On-Grid System Price in Pakistan
The cost and expense of an on-grid solar system in Pakistan depend on various factors, including system capacity, brand, and installation quality.
Common home on-grid home solutions prices form.
| System Capacity | Estimated Unit Production per month | System Cost | Inverter Capacity | Solar Panels |
| 5KW | 600 | 700 to 750k | 10KW | 9 x 585W |
| 10KW | 1,200 | 920 to 970k | 10KW | 18 x 585W |
| 15KW | 1,800 | 1225 to 1275k | 15KW | 27 x 585W |
Comparison Between On-Grid, Off-Grid, and Hybrid Solar Systems
| Feature | On-Grid | Off-Grid | Hybrid |
| Grid Connection | Yes | No | Yes |
| Battery Requirement | No | Yes | Optional |
| Cost | Low | High | Moderate |
| Ideal Use | Urban areas with stable grid | Remote areas without grid access | Areas with partial grid access |
Ideal Use Urban areas with stable grid Remote areas without grid access Areas with partial grid access
What Makes On-Grid Systems Different From Hybrid Systems?
- On-Grid Systems: Connected directly to the utility grid without battery dependency, making them more affordable.
- Hybrid Systems: Combine grid connection with battery storage, offering backup power but increasing costs.
Which Capacity Makes the Best Solar System for Homes in Pakistan?
The ideal capacity depends on your household’s energy consumption. Common recommendations include:
- 5kW System: Suitable for average households with moderate electricity usage.
- 10kW System: Ideal for larger families or homes with high energy demands.
Subsidy on On-Grid Solar Systems in Pakistan
The Government of Pakistan supports solar adoption through net metering policies. Homeowners can export additional electricity to the grid and reduce their electricity bills. This initiative makes solar Energy a more viable and affordable option for households and businesses.
FAQs:
Q1: Does an on-grid solar system work during a power outage?
A: No, on-grid systems require the utility grid to function. During outages, the system automatically shuts down for safety reasons.
Q2: How long does an on-grid solar system last?
A: With proper maintenance, most systems last between 20 to 25 years.
Q3: Can I upgrade my on-grid solar system later?
A: Yes, you can add more solar panels to increase the system’s capacity as needed and depends upon the area available on the rooftop/ground.
Q4: Is net metering available everywhere in Pakistan?
A: Net metering is widely available but depends upon local electricity provider policies or DISCO’s such as IESCO, FESCO, LESCO, GEPCO, PEPCO, MEPCO, K-Electric etc.
