Planning to install solar for your house and still confuse regarding off grid or on grid solar!
Let us tell you.. you are not alone in this.
But in order to make the right choice you need to understand the basic difference between both the grids. Though a reputable installer might guide you but doing some sort of hard work on yourself will not hurt you.
Whether you want to go for an of grid solar system or on grid system is completely important to know while installing solar panels.
As far we know it mainly depends on location, your energy consumption and grid availability. also on-grid solar system is connected with the utility grid and the off-grid solar system works independently.
So let’s begin with elaborating more On-Grid vs Off-Grid Solar system.
We will clear out the terminologies before moving on to the main differences between On-Grid vs Off-Grid Solar.
#1. On-grid Solar System Overview
According to the on-grid solar system installation guide it is always connected to the utility grid of the supply company. It is the more popular way of solar installation.
With on-grid solar systems, you are safer in terms of backing up. You are always connected to the grid; all the lapses and faults in your power supply of the solar system.
There are a few benefits of how does an on-grid solar system work. You can supply all the excess energy your system produces to the grid.
You can either get the compensation for this electricity you supply to the grid or can avail of net metering. Through net metering, you can get back the same amount of energy you supply to the grid when you need it.

Net metering is an amazing way to power your home day and night with the help of a solar system. It is an amazing advantage of installing an on-grid solar system for home.
Advantages:
- The on-grid solar system cost is effectively less than the off-grid system. It is due to the fact that it requires a few pieces of equipment less than the off-grid systems.
- With the on-grid systems, you can get your initial expenditure faster. There is more than one way of saving or making money through the on-grid solar system.
- If you are a residential user, you can make a side income by selling the excess power you make.
Drawbacks:
One of the major on-grid solar system disadvantages is that it won’t work during a blackout. The on-grid solar system is directly connected to the grid network. It turns off the supply during any faults because of safety reasons.
Applications:
Residential users in well-developed areas where the electricity supply is adequate can use the on-grid solar system.
As we have enough info about the on-grid solar system now, let’s talk about the off-grid system.
#2. Off-Grid Solar System Overview
An off-grid solar system works independently without any connection with the grid supply. In the off-grid solar system, batteries play an important role.
The batteries store all the excess power that the solar system generates. This power storage comes into use at night or when the solar system is unable to generate power.
With the best off-grid solar system Australia, you are completely self-sufficient to power all your electricity needs.

Being self-sufficient for fulfilling all the power requirements, you don’t have to pay any power bills. This saves a lot of money that you can count as the payback of the off-grid solar system price.
You can add batteries according to your will to the off-grid solar system Australia. The batteries can store power for the times when the solar system is unable to generate power such as nights, cloudy days, etc.
Advantages:
- The off-grid solar systems do not rely on the grid and can work independently.
- The power blackouts and any other faults in the electric supply infrastructure won’t affect the performance of the off-grid solar systems.
- They can store enough electricity to power your home for weeks by using heavy batteries.
Drawbacks:
The batteries can add up to a few grands on the off-grid solar system cost. The effective price of the off-grid solar system is much higher than that of the on-grid solar system.
Applications:
The off-grid solar systems are the best to install in remote areas where the power supply is not very good.
To mitigate the frequent power cuts, the off-grid solar system is a very good remedy. It is long term solution for frequent power blackouts.
We have now enough information about the on-grid and off-grid solar power systems. We know their functions, their applications, and also the On-Grid vs Off-Grid Solar system pros and cons.
We are now ready to discuss the differences between the two types of solar systems. So let’s begin…
What’s The Difference Between On-Grid And Off-Grid Solar Systems?
As we already know the main difference between the two types of solar systems is the basic structure of the installation.
The on-grid solar system is connected with the grid supply and the off-grid solar system is independently sufficient. The next few paras contain some other key differences between on-grid and off-grid solar systems.
After going through all the differences, you can easily decide whether to go for an On-Grid vs Off-Grid Solar.

Following are the differences between off-grid and on-grid solar systems:
#1. Electricity Access
For On-Grid:
You have direct access to the electricity that the solar power system produces. All the appliances in your home can directly draw power from the solar system when it is producing electricity.
As it is connected to the grid as well, you always have the access to the grid electricity as well. When the supply of the solar system goes down, the appliances can draw power from the grid.
The backing up for power supply by the grid is the main feature of on-grid solar system design.
For Off-Grid:
When the solar panels are producing electric current by converting the Sunlight, the solar system is the source of access to electricity. The current also charges the batteries simultaneously.
When the panels are unable to produce electric current at night or on cloudy days, the batteries power all the electrical and electronic appliances.
Batteries are the major difference between the off-grid and on-grid solar power kits.
#2. Handling the Excess Power Generation
For On-Grid:
In the on-grid solar power systems, the excess power goes back to the grid. You can make this excess power useful in two different ways.
You can use the same amount of power that goes into the grid at night by taking it back. You can also sell that power to the grid on feed-in tariff rates.
For Off-Grid:
All the excess power that an off-grid system generates goes into the battery storage. This power storage comes into use when the off-grid system is unable to produce electricity.
You can add a big battery backup to store more power for an extra cushion. However, the battery adds to the cost of the off-grid solar system and makes it more expensive.

#3. When The Grid Goes Down
For On-Grid:
When the grid goes down; the on-grid solar systems stop working. The on-grid solar system calculator suggests that it is cheaper than the off-grid system.
But this drawback gives a solid setback to its performance in the straight comparison.
For Off-Grid:
There is no effect on the working of the off-grid solar systems when the grid goes down.
The off-grid systems are fully disconnected from the grid and are on their own. This gives it a slight edge in the head-on comparison with the on-grid systems.
Well, these were the key differences between the on-grid and off-grid solar power systems. Both the systems have their pros and cons.
The on-grid system is cheaper, but it goes blank when the grid goes down. On the other hand, the off-grid system is relatively expensive, but it works independently of the grid.
However, we think all this data is sufficient to give you an idea to pick one of the two types of solar systems convincingly.
But if you still have any confusion in deciding between off-grid vs on-grid solar power systems for home; you can reach out to us.
