On-Grid and Off-Grid Solar Systems: Transforming Energy Solutions in Pakistan

As the global demand for sustainable energy rises, solar energy has become a crucial solution to address energy shortages and environmental concerns in Pakistan. Solar Advisor offers two primary types of solar systems — On-Grid and Off-Grid — each tailored to meet unique energy needs.

What is an On-Grid Solar System?

An On-Grid Solar System, also known as a grid-tied system, is connected to the national electrical grid. Photovoltaic (PV) panels capture sunlight and convert it into electricity, which is then transformed into alternating current (AC) by an inverter for use in homes and businesses. Excess electricity generated is sold back to the grid through net metering, offering significant savings on energy bills without the need for batteries. This system is ideal for urban areas with reliable grid access and offers an affordable, efficient, and sustainable energy solution.

What is an Off-Grid Solar System?

An Off-Grid Solar System operates independently of the national grid, making it perfect for remote or rural areas with limited electricity access. These systems generate power from solar panels and store it in batteries, ensuring a consistent energy supply even during low sunlight or high demand periods. This self-sufficient solution provides reliable power for homes, businesses, and equipment without relying on external energy sources.

How These Systems Work

• On-Grid Systems: PV panels generate power, which is converted into AC by an inverter and used to run electrical appliances. Excess energy is sent back to the grid, and in times of low sunlight, electricity is drawn from the grid to ensure uninterrupted power.
• Off-Grid Systems: PV panels convert sunlight into electricity, stored in batteries for later use. This stored energy powers appliances and systems, making it an independent energy solution.

Benefits and Applications

• On-Grid: Cost-effective, eliminates battery expenses, supports net metering, and reduces dependency on fossil fuels. Suitable for urban areas with grid connectivity.
• Off-Grid: Ideal for remote areas, provides reliable power where grid access is unavailable, and ensures energy independence.

The Solar Advantage in Pakistan

Pakistan’s vast solar potential — estimated at 2.9 million megawatts — makes solar energy a game-changer. On-Grid systems are becoming increasingly popular in urban areas, while Off-Grid systems are transforming rural and remote regions. Government initiatives like net metering and policies by the Alternative Energy Development Board (AEDB) are further promoting solar adoption.

Cost Overview

• On-Grid Systems: Prices range from PKR 200,000 to PKR 500,000, depending on size and type, with long-term savings through reduced electricity bills and net metering.
• Off-Grid Systems: Costs vary based on battery capacity and system size, offering a dependable investment for off-grid energy independence.

Whether you’re looking for grid-tied solutions to reduce electricity costs or stand-alone systems for remote locations, Solar Advisor provides expert solar energy solutions tailored to your needs, transforming energy challenges into sustainable opportunities.
