Difference Between On-Grid, Off-Grid And Hybrid Solar System ? Saudi Arabia (2024)
What is the difference between Off-Grid, On-Grid and Hybrid System-In terms of energy storage, on-grid systems do not need storage; off-grid systems use very large storage, and hybrid systems use a storage size depending on load requirements. In an on-grid solar system, when there's no power from the national grid, there is a blackout (if there's no storage).

Solar power has become an increasingly popular source of renewable energy in recent years. There are three main types of solar power systems: off-grid, on-grid, and hybrid. Each system has its unique features and benefits, making it important to understand the differences between them to choose the best option for a particular situation. In this article, we will explore the differences between off-grid, on-grid, and hybrid solar power systems, how they work, and their advantages and disadvantages.
1.On- Grid System –
On-grid solar power systems are a popular option for those who want to generate their electricity from renewable sources while still maintaining a connection to the national power grid. This type of system is also known as a grid-tied system and works in tandem with the local utility company or distribution company.
On-grid systems generate electricity from solar panels and use an inverter to convert the direct current (DC) electricity produced by the panels into alternating current (AC) electricity that can be used to power a home or business. Any excess power generated by the system is sent back to the national electric grid for compensation, which can be received through feed-in tariffs or net metering programs.
Feed-in tariffs involve receiving payment for the excess electricity that is fed back into the grid. This payment is typically based on the amount of electricity generated and can be a fixed or variable rate. Net metering programs allow homeowners to offset their electricity bills by sending excess power back to the grid, and the compensation they receive is calculated based on the difference between the amount of electricity generated and the amount of electricity used.
On-grid solar power systems are a cost-effective way to generate electricity from renewable sources because they eliminate the need for batteries to store excess energy. This means that homeowners can avoid the expense of purchasing and maintaining a battery bank while still being able to generate their electricity from solar power.
However, there are some disadvantages to on-grid systems. They cannot generate electricity during power outages, and they are reliant on the availability and reliability of the national electric grid. Despite this, on-grid solar power systems remain a popular option for homeowners and businesses looking to reduce their reliance on traditional sources of electricity while still maintaining a connection to the grid.
2.Off- Grid System
Off-grid solar power systems are a type of solar power system that operates independently of the national electric grid. This type of system is commonly used in remote areas that are not connected to the grid, or by individuals who want to reduce their reliance on traditional sources of electricity.
Off-grid solar power systems generate electricity from solar panels and store it in batteries for use when the sun is not shining. The batteries are connected to an inverter, which converts the DC electricity stored in the batteries into AC electricity that can be used to power a home or business.
Because off-grid solar power systems are not connected to the national electric grid, they require the use of batteries to store excess energy. This means that homeowners must purchase and maintain a battery bank, which can be expensive. However, the cost of the batteries is offset by the fact that off-grid systems provide reliable electricity even in remote areas that are not connected to the grid.
Off-grid solar power systems also require careful planning to ensure that the system is properly sized and that there is enough energy storage to meet the homeowner's needs. The system must be designed to meet the home's energy needs throughout the year, including periods of low sunlight and high energy demand.
Despite the initial costs and planning required, off-grid solar power systems offer several advantages. They provide energy independence, reduce reliance on traditional sources of electricity, and are a reliable source of electricity in remote areas. They also have a low environmental impact, as they do not emit greenhouse gases or other pollutants associated with traditional sources of electricity.
3. Hybrid System
Modern hybrid systems combine solar and battery storage into one unit and are now available in a variety of shapes and sizes. Because the cost of battery storage is decreasing, systems that are already connected to the power grid can begin to benefit from battery storage as well. This entails storing solar energy generated during the day and using it at night. When the stored energy runs out, the grid serves as a backup, giving consumers the best of both worlds. Hybrid systems can also charge the batteries using low-cost off-peak electricity (typically after midnight to 6 a.m.).
There are several approaches to designing hybrid systems, but we'll keep it simple for now.
- The bank of batteries. Once the solar power is used by the appliances on your property, any excess power is sent to the battery bank in a hybrid system. When the battery bank has been fully charged, it will no longer receive power from the solar system. The energy from the battery can then be discharged and used to power your home, typically during peak evening hours when electricity costs the most.
- The meter and the power grid. Depending on how your hybrid system is configured and whether your utility allows it, excess solar power not required by your appliances can be exported to the grid via your meter once your batteries are fully charged. When your solar system is not in use, or if the usable power in your batteries has been depleted, your appliances will begin drawing power from the grid.
Other distinctions include:
- On-grid systems do not require storage; off-grid systems require very large storage; and hybrid systems use storage based on load requirements.
- When there is no power from the national grid, there is a blackout (if there is no storage) in an on-grid solar system. When the national grid fails, the energy storage (battery) in off-grid and hybrid solar systems provides backup power.
- Because of the storage, off-grid solar systems are the most expensive, followed by hybrid solar systems, and on-grid solar systems are the least expensive.
FAQ-
Which is better, on grid, off-grid, or hybrid?
Key benefits of hybrid systems
You'll use less grid electricity than you would with a traditional grid-tied system. While hybrid setups are grid-tied, they come with solar battery storage, which means you can maximise consumption of the power generated from the panels.
What is the difference between a hybrid and an on-grid inverter?
On grid inverters are designed to work directly with the grid, without battery storage, and feed excess energy generated by solar panels back to the grid. Hybrid inverters, on the other hand, are designed to work with battery backup systems. Excess energy generated by solar panels is stored in the battery system.
What are the components of a hybrid solar system?
Any good hybrid system will have at least four main components. These are solar panels, the solar inverter, the switchboard, and battery storage. Solar panels are the most prominent part of the hybrid system as they're commonly exposed on the roof of a house or in a yard.
Can a hybrid solar inverter work without a battery?
Solar Panel Installation Without Battery Power As A Backup System. A hybrid solar inverter can work without batteries. This type of system is attached to solar panels and to the power grid which supplies power from both.
Which is cheaper on-grid or off-grid solar system?
Compare the upfront investment for on-grid and off-grid systems. On-grid systems typically have a lower initial cost because they don't require expensive battery storage. If you're concerned about the initial expense of an off-grid system, explore solar financing options or incentives available for solar systems.

Can hybrid inverter charge battery from grid?
Even better, because the amount of solar power that is available can vary depending on the weather and the time of year, a hybrid inverter can, if necessary, draw power from the electricity grid to charge your battery storage system.
Is a battery required for an on-grid solar system?
With an on-grid system, there is no need for batteries as the house or building is still connected to the city's electrical grid. This means during the times when the solar system cannot produce energy, such as when the sun is not shining, the house would pull from the grid.
How to size a hybrid solar system?
To calculate the size of the solar system you need, you will need to divide your daily energy usage by the number of peak sun hours you receive. For example, if you use 30 kWh of electricity per day and your location receives 5 peak sun hours per day, you will need a 6 kW solar system (30 kWh divided by 5 hours).
Can a hybrid run without battery?
In certain hybrid vehicles, you can drive without the battery, however, it is not recommended, as it can cause permanent damage to the hybrid system.
Can a hybrid inverter work off-grid?
Yes, a hybrid inverter can work without a grid connection!
Essentially, they manage power from solar panels, the grid, and batteries. In an off-grid scenario, the inverter draws energy from solar panels or batteries.
