As electricity bills soar, more and more are opting for solar panel systems. In addition, there are some who are opting for this source of energy for one other reason – clean energy. 

There’s no questioning that having a solar panel system at home can reduce your electricity cost. Also, it is a reliable power backup option. However, despite their soaring demand, not everyone knows how to choose the best solar panel system for their home. If you’re one of them, this blog is for you. 

What to look for when buying solar panels? Which is the right solar system for my home? Here, you’ll find most of the answers regarding solar panel buying guide.

Check feasibility

Before you get a solar panel system for your home, it is important to check their feasibility. There are mainly two things you need to check.

  1. Available space
  2. Sunlight

You can contact any solar panel selling company or ask their technician to know how much space is required to install the solar system at home. It depends upon the size of system you require. Number and size of solar panels vary as per the system size so it is important to see if you have required space for this purpose.

Then, you need to check the availability of sunlight. In most areas of Pakistan, there is enough sunlight available to cater the needs of an average household. 

Which system to choose?

There are three main types of solar systems for households. 

  • Off Grid
  • On Grid/net metering system
  • Hybrid

Off grid

It is the system in which solar panels are attached to a battery via an inverter. It is not integrated with the main electricity grid. This system provides direct power in the daytime and charges the battery as well. You get electricity backup in the case of a power outage due to batteries attached with it. You need larger batteries for this solar panel setup as you are not using power from the grid. Due to the larger batteries, its price is generally higher.

On Grid / net metering system

It is the system in which your system is connected with the main power grid through a net metering system. There isn’t any battery involved in this system. Excessive electricity your solar panel system produces is transferred to the main grid in exchange for electricity from the grid in exchange for units. You can consume those units in the night when there is no sunlight. This reduces the electricity bill significantly.

The drawback of this system is no electricity backup. You will have to get a separate UPS or generator for power backup.

Hybrid (net metering + batteries)

Hybrid solar panel systems are highly popular as they offer all the benefits of both systems without inheriting their drawbacks. It charges the battery as well as transfers electricity to the main grid via a net metering system. 

The system works by providing enough power to take the house load completely. After that, the solar inverter in the system charges the batteries. When the batteries are charged, it transfers the excessive electricity to the main grid. So, it is considered the most efficient system. But it is also quite expensive.

Depending upon the requirements, you can choose any one of the above-mentioned system types for your home. 

Size or capacity of solar panel system

Here comes a big factor that confuses many people. Size of the solar system is a pretty significant factor you need to consider before making your buying decision. It mainly depends upon your electricity consumption.

From the average electricity bill, you can calculate the average monthly electricity units (kW) consumed. With this average, you can easily calculate daily average electricity unit consumption (kW) by dividing the number with 30. The following table shows which system you should get as per the daily unit consumption. 

Daily Units Consumption (kW)Capacity (Watts) Approximately
51,250W / 1.25kW
102,500W / 2.5kW
205,000W / 5kW
4010,000W / 10kW
8020,000W / 20kW

Solar Batteries

If you are going to get an off-grid or a hybrid system, battery capacity is an important element. 

Capacity of the battery (kWh) depends upon the backup time you need. You can get batteries with larger capacity if you need more backup time in the case of power outage. However, you should also consider the recommendations of the manufacturer.

There are many types of solar batteries such as gel, dry, lithium-ion, etc. Lithium ion batteries are the best but come at a higher price. Different solar panel systems require specific types and quantities of batteries. 12V batteries are the most common one in this regard.

Solar Inverters

A solar inverter converts the variable DC electric signals from the solar panel cells into a usable frequency of alternating current (AC). Choosing the right inverter is very important too. Generally, the inverter and solar panel have the same number. If you are getting a 5kW solar panel system for your home, you are most likely to get a 5kW inverter as well. It is important to get an inverter with a faster charging rate. 

Calculate your power usage kWh (Wattage)

It is easier to get an estimate of power usage from your electricity bill. However, you can also calculate your power usage with respect to different electric appliances. Here is the estimated wattage of different appliances.

Panel Types (Cells)

Types of panels have huge significance. It is important to pay proper attention to it when getting solar panels for your home. Efficiency, price, production rate, etc. depends upon their type. Here are the 4 types that you will find in the market. 

1.Concentrated PV Cell (CVP)

Highest efficiency / most expensive

2.Monocrystalline Solar Panels (Mono-SI)

2nd highest efficiency / expensive

3.Polycrystalline Solar Panels (p-Si)

2nd lowest efficiency / economical

4.Thin-Film: Amorphous Silicon Solar Panels (A-SI)

Lowest efficiency / cheap

Panel Size

Panel size and production capacity matter a lot. You should go for a panel that has a larger size. But keep in mind that many panels have a large size but produce almost the same amount of energy as the smaller ones. So, get the panel that produces more energy among the others.


No doubt, quality matters a lot when selecting a solar panel. We are talking about the quality of panels (plates), inverters, and batteries. It is linked with the manufacturer you select. Choose the brand that is trusted in the market. It is also important to get the panels from a brand that provides more warranty. 

In the market, you will find many Chinese panels. You have to ensure that the panel has A or A+ quality if you want to choose an economical Chinese solar system for your home. 

Direction of Panels

Though the technician is the best person to help you with this, generally south is the best direction for your solar panels to face. However, it can be changed depending upon different factors. The idea is to get the maximum sunlight. It is the reason why the panels are placed at an angular position. 

Custom Made Vs Ready Made Structure

An important thing to consider is the structure or frame on which the solar panels are going to be installed. There are two options – ready made and custom made. Many choose the second option as they can choose the quality of the frame and get it designed specifically as per the space available. This helps in maximizing the utilization of space but increases the cost as well.

Solar Panel Price in Pakistan

Solar panel price varies depending upon the company, warranty, panel quality, system type, etc. Generally, the average price of a simple on-grid (without batteries) 1kW system is Rs.100,000. Here is a chart that shows the average price of different solar panels in Pakistan.
