Off-grid solar system

Generally, a 5-kilowatt off-grid solar system costs around PKR.400,000 to PKR 700,000 before accounting for solar tax credits and rebates. The expense of an off-grid solar system has an even more comprehensive range as it is available in many sizes and components that impact the price. They can drive up the total expense, as a simple battery can cost depending on the size of your off-grid system and the domestic energy usually consumed.

What is the off-grid solar system?

An off-grid solar system runs independently from the power grid. These systems stress living off-grid, a lifestyle emphasizing energy independence and self-reliance. Living “off the grid” has recently become highly favoured due to the high cost of electricity, fuel, food, and other necessities of life. There has been a massive rise in electricity costs since the last decade, causing many people to switch to other forms of power for domestic use.

What is the grid and off-grid solar system?

On-grid

Also identified as grid-tied, these systems are connected to the utility grid and add electricity to what you get from your utility company. A battery is unnecessary to store excess power energy, as the grid acts as the energy reservoir. These systems are usually cost-friendly and more accessible to set up. They can also favour you in that you may also be able to get paid for excess energy produced by your system. 

Off-grid

These systems are not grid-tied, as they can be seen, are not connected to the utility grid, and are entirely self-sufficient. The stored energy in the battery is utilised in the absence of sunlight, mainly at night. Off-grid systems have the disadvantage of being expensive to install but also have the advantage of being highly reliable in the long run. You will not have to face any blackouts or power outages. Furthermore, there will be no need to pay any electricity bills.

Types of off-grid solar system

 AC (alternating current)

 DC (direct current)

What is a grid in solar panels?

It is solely the electric connection with the solar panels. A pattern of metal lines and wires connecting the individual photovoltaic cells is on the surface of the solar panels. Some other uses include the transport of current, reduced electrical resistance, and increased efficiency. The grid lines may also provide structural support to the cells. Several grid patterns exist, such as standard grid, thin film grid, PERC (passivated emitter and rear cell), and MWT (metal wrap through). The efficiency and reliability can affect the design of the grid. Solar panel systems connected to the grid are called grid-tied, on-grid, or grid-connected photovoltaic systems.
