Off-Grid Solar System in Pakistan

The idea of generating free electricity is not limited to only the metropolitan or suburban areas. This is also relevant for the far-off places where the grid electricity is not available. For such places, the on-grid or hybrid solar systems do not make sense because there is no grid to connect these systems.

In such places or scenarios, where one has to live off the grid, the off-grid solar system makes the most sense. The Off-grid Solar System in Pakistan are mostly used in areas where there is no grid electricity available. It is mostly used by the defense sector to power bases in remote areas.

What is An Off-Grid Solar System?

An Off-Grid Solar System is the one which does not need to be connected to the grid in order to work. This system requires a set of batteries which can store energy that can be used at night.

How Off-Grid Solar System In Pakistan Works?

An off-grid solar system functions in a similar way to other solar systems. It has some minor differences in the way it works because it is not connected to the grid. The basic overview of the working of an off-grid solar system is as follows:

Electricity Generation

The electricity is generated by the solar panels. The process starts when the radiation from sun hits the surface of the solar panels. The electrons in the silicon atoms absorb this energy and start moving freely out of their orbits. This flow of electrons is the electric current which is produced in the form of direct current or DC.

Transmission and Conversion

The electric current produced by the solar panels is collected in wires and transmitted to the Off-Grid Solar Inverter. The off-grid inverter then converts the electricity produced by the solar panels in to alternating current or AC. This is then supplied to the main electricity board.

Usage and Storage

The switch board is responsible for distribution of electric current as per usage. The excess electricity produced by the panels is not transported to the board, but it goes to the Solar Batteries. These are used as primary power source at night when the solar panels are not producing electricity.

Efficiency of the Off-Grid System

The efficiency of the off-grid solar system depends upon the following factors:

The efficiency of the solar panels because it describes how much of the sunlight absorbed has been converted to the electricity.
The inverter efficiency is an indication of how much DC is converted into AC for usage. This is usually quite high, approximately 90% on average.
The wires should be conductive with low friction for loss during transmission of electricity.

Advantages and Disadvantages Of Off-Grid Solar Panels

The off-grid solar panels have a lot of benefits and some disadvantages as well. Here we are going to cover the primary pros and cons to help you decide better if you want this system or not.

Pros of Off-Grid Solar System

The top benefits of using an off-grid solar system are as follows:

Energy Independence

You can become totally independent of the utility provider by going off the grid. It can be quite liberating to have complete control over your power. Your local utility company’s terms and conditions will no longer apply to you. Increased energy costs won’t have any impact on you. Being off the grid might also be very helpful in regions that frequently experience extreme weather conditions.

Access to Power in Remote Locations

Off-grid solar energy offers a solution to power isolated areas where utility power is either unavailable or where building power lines would be too expensive. With this choice, you can power holiday houses or cabins that are located far from crowded areas and live more independently.

Most energy-conscious choice

Going off-grid with your solar project has the additional bonus of being the most energy-conscious decision you can make. You can source locally and reduce the environmental impact of the utility company by producing your own electricity. You can precisely monitor your power consumption using off-grid solar. Off-grid solar encourages energy efficiency because the amount of energy you have is constrained.

No Blackouts or Load Shedding

It gives you a sense of security and relief to keep your electricity running during local utility power outages. Power outages are inconvenient whether they are anticipated or unanticipated. When there is a blackout, your power won’t go out with the rest of the neighborhood if you have off-grid solar. This is especially useful if you have appliances like medical gadgets or refrigerators that require constant electricity.

Cons of Off-Grid Solar System

This system has some cons as well which are as follows:

High Upfront Cost

Although getting off the grid will eliminate your need for an electricity payment each month, off-grid solar requires a larger upfront investment than grid-tied solar. Off-grid solar needs a battery bank to store produced energy in addition to the materials list for grid-tied solar. Up to 30 to 40 percent of an off-grid system’s initial cost can be attributed to these batteries. Due to the additional cost, off-grid solar will cost you significantly more than grid-tied solar. You won’t be able to later recoup your investment because off-grid solar systems are unable to sell energy back to the power grid.

Limited Energy Storage

The storage capacity of off-grid solar projects is constrained and solely depends on the battery bank you buy. You must decide how much energy storage you require while organizing an off-grid solar project. Once you’ve bought and installed your battery bank, you’ve determined how much energy storage is possible for you. Energy efficiency cannot be disregarded because an off-grid solar system has a finite amount of energy accessible. To reduce your energy use, you might need to alter your lifestyle.

No Backup Sources

Off-grid solar isn’t connected to the grid, so it can’t draw power from it if it runs out. There’s a danger you’ll exhaust all of your reserve energy if the weather is consistently cloudy. Power wouldn’t be available with an off-grid system until the solar system had a chance to recharge.

High Maintenance with Shorter Lifespan

Batteries are not only an expensive initial investment, but they also need upkeep and have limited lifespans. Typical batteries typically last between 5 and 15 years before needing to be replaced.

Usage

The utility of Off-grid solar system in Pakistan in various sectors in as under:

Residential Off-Grid Solar System in Pakistan

The Residential Sector has a very limited usage for this solar system in cities and villages where the grid electricity is available. The off-grid solar system is more suitable in remote areas such as in the northern region or deserts or simply the places where there is no grid electricity available. In regions where grid electricity is available, it is better to use On-Grid Solar System or Hybrid Solar System.

Commercial Off-Grid Solar System in Pakistan

Similarly, the Commercial Sector is mostly based in city areas. The off-grid system is better suited to the commercial setups which are in remote regions because otherwise operating off the grid is not viable.

Industrial Off-Grid Solar System in Pakistan

The Industrial Sector require a huge amount of electricity to operate. Even several mega-watts of solar system installed at industries are unable to fully power their operations. For this reason, they require grid connection to operate at their best. This shows that off-grid systems are not a good match for industrial operations.

Agricultural Off-Grid Solar System in Pakistan

This sector can use the off-grid system with highest utility because in some villages the grid electricity is not available. Even if it is available, high load shedding makes it useful to switch your tube wells to off-grid solar systems.

Best Usage

The off-grid system finds its maximum utility for every person, business or sector which is located in the remote areas and has no access to the utility stations. They can live the best with off-grid solar system.

Technical Details to Size An Off-Grid Solar System

Off-Grid Solar System in Pakistan

When establishing an off-grid solar system, determining the amount of the system you require is an early and extremely critical stage.

It will have an impact on the type of equipment you require, the amount of labour required for installation, and, of course, the project’s overall cost. The size of a solar installation depends on how much power the system must produce.

There are two methods you can use to determine the number you require, and they are both based on:

Your current usage
Load evaluation
Technical Specifications of Major Components

Solar Panels

You should get highly productive Solar Panels because you need a lot of electricity that can be stored for use at night, especially in the winter season. For this get Monocrystalline, Bifacial Solar Panels with production capacity of at least 500kW for space optimization.

Racking and Mounting

The mounting needs to be the best because if you are in a remote area, you are likely to experience the weather at extreme conditions.

Wiring

Your wiring needs to be of the best conducting metals like 100% copper with appropriate insulation so that you can minimize electricity loss.

Solar Off-Grid Inverter

Pick high efficiency Solar Inverters because they need to convert DC to AC with maximum efficiency. Your off-grid inverter also needs to be highly durable so that it can last for a long time.

Batteries

Off-grid batteries should charge effectively to prevent wasting the solar array’s precious energy. Off-grid inverter chargers have a high surge draw, discharge current, and charge current that off-grid batteries must be able to tolerate. A maintenance-free battery is very desirable because access to off-grid locations is not always simple. The useful lifetime of the selected battery will be impacted by high and low temperatures, so these conditions must be taken into account.

Off-Grid Solar Systems in Pakistan – No For Everyone

The most practical energy source when grid access is difficult or unattainable is off-grid solar. It is frequently the greatest choice for people who are dedicated to living a low-impact, sustainable lifestyle. On the other hand, going off-grid is probably not for you if you’re a conventional homeowner who lives in or close to a city or town.

This is due to the high cost of off-grid solar systems for houses, which rarely result in cost benefits over utility power. Additionally, because off-grid solar is so expensive, homeowners are only able to construct very tiny systems, which results in significant lifestyle compromises for the home’s occupants.

Select the Solar System Capacity for Your Home Based on Monthly Electricity Units:

Solar power systems are available in various capacities and types. If the usage of electricity is higher, then the capacity of the solar system is greater as well, so the required capacity of the solar system is directly proportional to or depends upon the electricity usage of the consumer.
