What Are On-Grid and Off-Grid Solar Systems?

The need for both on-grid and off-grid solar systems arose as a result of two primary factors:  

  • The rising cost of electricity for commercial use.
  • The damaging effects of electricity derived from fossil fuels on the environment.

People began searching for better alternatives, resulting in the widespread adoption of solar-powered electricity generation systems. Moreover, high-efficiency solar panels facilitate electricity production to fuel the industrial sector.

To choose the best solar energy system, it is essential to understand both on-grid and off-grid solar systems thoroughly.  

What Is An On-Grid Solar System?

On-grid solar systems, called grid-tied systems, are connected to the electrical grid. They provide a reliable energy source, supplementing utility power and, in some areas, even returning excess energy to the grid via net metering.

There are times when connecting to the grid is necessary, such as when your photovoltaic (PV) solar panels are not producing enough power or when the batteries that store excess solar power are empty and need time to recharge.  

Inverters are needed to transform the DC produced by solar panels into the AC power required for use in your home or business throughout the recharging process.    

What Are The Components of On-Grid Solar System?

This on-grid solar system uses solar or micro-inverters and is connected to the public electricity infrastructure; it does not require batteries. Typically, an on-grid photovoltaic system comprises:

  • Solar panels
  • Inverter
  • Switchboard
  • Net meter
  • Electricity grid
  • Home energy consumption

What Are The Pros and Cons of On-Grid Solar System?

Most residential properties will utilize this on-grid solar system, as you are protected if your solar system is under or over-produces. Your electric utility company serves as your battery space.

The advantages of an on-grid solar system are as follows:

  • This utility is a 100 percent efficient battery, so there is no need to invest in a separate, costly battery backup system to store energy surpluses.
  • You will not be required to change your lifestyle or energy-saving practices.
  • You will enjoy receiving credits from your local electricity grid provider for any excess energy you have generated in addition to your already-reduced electricity bills.

Among the disadvantages of grid-connected solar systems are:

  • Due to safety concerns, on-grid solar systems cannot function or generate electricity during an outage because they lack batteries. As blackouts typically occur when the electricity grid is damaged, if the solar inverter continued to feed electricity into a damaged grid, it would endanger those repairing the defect or faults in the network.
  • They cannot generate solar energy and lower your electricity bill at night or without sunlight.

What Is An Off-Grid Solar System?

Off-grid solar systems are entirely self-sufficient and not connected to the electric infrastructure. Consequently, they are frequently helpful in remote locations where grid connection could be more practical and possible. They are also popular among homeowners who desire total independence from the power grid.  

Off-grid solar systems have the advantage of not being affected by power disruptions. Solar panels convert solar power into electricity, which is then deposited in a solar battery (or batteries).

Off-grid solar energy provides energy autonomy. You can access electricity even if the utility is down if you generate and store enough solar energy. For example, Jackery Solar Generators let you add more batteries and enhance your output as your power needs grow.    

What Are The Components of Off-Grid Solar System?

Because an off-grid solar system is not connected to the public energy grid, it is necessary to have a battery storage system. Off-grid solar power systems have to be engineered to generate enough electricity throughout the year and have adequate battery storage to satisfy the requirements of the individual household. Typically, an off-grid solar system comprises:

  • Solar panels
  • Solar inverter
  • Battery
  • Home power consumption

What Are The Pros and Cons of Off-Grid Solar System?

What are the advantages and disadvantages of an off-grid solar system? The energy produced by the off-grid solar system is used to power the residence and appliances, with any excess energy stored in batteries for use at night or on a cloudy day.

These are the advantages of an off-grid solar system:

  • If you are on an off-grid system, your energy consumption is entirely self-sufficient, as you are not connected to your local grid's electricity system or utility company.
  • The energy cost is predictable because you can amortize the purchase and installation costs over the system's lifespan. Without unanticipated future expenses, the return on investment can be calculated with a solid warranty. Compared to the frequently high and variable commercial energy costs, it is an attractive proposition.
  • They encourage you to use electricity efficiently, which benefits the environment.

Despite its many advantages, off-grid solar systems have disadvantages:

  • Off-grid systems necessitate the purchase of a secondary battery, which can be cumbersome and costly. Solar battery systems must be routinely maintained.
  • Off-grid options are not eligible for the feed-in tariff because the system is disconnected from the grid.

What Is Hybrid Solar System?

A hybrid solar system incorporates the advantages of both on-grid and off-grid solar. Hybrid systems, like off-grid systems, can store energy in batteries but can also link to the grid. If you have battery storage and are connected to the grid, you can use the grid as a backup power source when your cells run out and may be eligible for net metering.

A stable source of electricity can be provided by hybrid systems if the power grid is down or if your solar panels cannot provide an adequate amount of energy. A hybrid system's batteries can store excess solar energy during the day and supply your residence with power at night or during periods of low solar production. 

hybrid solar system

In addition, when the batteries are depleted, the system can draw power from the grid to guarantee a continuous electricity supply. Two methods for connecting grid-connected solar systems to batteries are AC Coupling and DC Coupling.

On-Grid Solar System VS. Off-Grid Solar System

The difference between an off-grid and an on-grid solar energy system is the latter's connection to the utility grid. Whether you have an on-grid or off-grid solar system will affect how you get power, what happens when the grid goes down, how you get billed for electricity, and what tools you need to handle extra power.  

Working Principles

The working principles of an on-grid solar system should begin with the configuration of solar modules absorbing sunlight and converting it into electricity. DC is the type of current produced.

The solar inverter converts the DC to Alternating Current (AC), powering electrical appliances. This energy is then transmitted to the grid and distributed for daily use. A net meter is a vital feature. It is a device that records the power supplied to the utility and the amount consumed.

The energy produced by the sun during the day is stored in batteries, as the off-grid solar system is not connected to the power infrastructure. This strategy is effective for homes without access to the grid's electricity and is entirely self-sufficient.

Homes use the power stored in the batteries at night and during periods when solar panels cannot produce enough electricity.

Excess Production

On-grid solar systems can be profitable if they produce more electricity than necessary. If your utility company supports net metering, you can earn money by transmitting excess energy back to the grid.

Your solar system may produce excess power depending on the day you use electricity. Send the power to the grid and get paid for it instead of storing it in batteries like you would with an off-grid solar system.  

Many individuals in the United States will be compensated through a process known as net metering. Net metering occurs when the utility company pays or credits your account for solar-generated electricity sent to the grid. (Source: National Renewable Energy Report)

Most off-grid solar systems are made to generate "extra" electricity during the day, which is stored in batteries. The conserved energy can then be utilized when the system is not producing, such as at night or during cloudy weather.

Electricity Bills

Choosing an on-grid system may result in minimal charges on your electricity account, even if your solar system provides 100 percent of your energy needs.  

You will only receive a single electric bill if your PV system is connected to the grid. However, even without an electric account, off-grid systems are frequently more costly due to the additional equipment, such as batteries, required to make them functional.

Power Outages

By connecting to the utility, you have constant access to electricity. However, you are subject to certain restrictions. If your grid-tied solar system fails, switching to an on-grid solar system with battery backup is the only way to keep utilizing power.

While this is a disadvantage of on-grid solar systems compared to off-grid solar systems, consider adding batteries to your on-grid system if maintaining power during a blackout is vital to you.

Regarding the off-grid solar system, it operates independently of the electrical grid. If a severe storm or other event removes the power, your solar system will continue functioning. There will be no modifications to your service or electricity access.

Alternatively, you can choose a portable solar system for disruptions and emergencies. Portable solar generators can provide much-needed power in an emergency during a power disruption. When the power is out and there is no other light source, a solar generator can help first responders see what they're doing and provide aid safely.
