Are you thinking about installing a solar energy system at your house or company, but aren’t sure whether to go off-grid or on-grid? Before you go ahead, you need to grasp the fundamental difference between off-grid and on-grid solar power systems in order to make the best decision. Knowing the major differences between the two will make your decision making easier — and can save you money.
In this article we’ll go through everything you need to know to determine the best solar option for your home. Let’s comprehend the key differences between off-grid and on-grid solar systems by looking at the benefits and drawbacks of the two along with distinctive features of each.
On-grid Solar Systems
What does this term really mean?
The energy systems that are directly connected to the utility electricity grid are known as on-grid solar power systems. If your solar array produces an excess of electricity that you don’t consume, the excess power is channelized into the utility network, and consumers are reimbursed for it. These systems work in collaboration with the electrical grid. When there isn’t enough sunshine to fulfil your business’s needs, the system uses grid power. When your power consumption is excessive and you want to save money on your electricity bills, these solutions are ideal. With or without net metering, on-grid systems can be installed. These systems are not affected by power outages because they are connected to the main grid.
Applications
On-grid solar systems can help businesses meet their daily needs while also generating revenue from the excess electricity generated. Buildings can generate enough solar energy to operate appliances, lights, and water heating systems on bright sunny days.
Advantages of On-grid Solar Systems
On-grid solar systems come with a huge bunch of benefits:
- Solar systems that are connected to the grid are incredibly cost-effective and simple to set up. There are no batteries that need to be replaced on a regular basis. As a result, it’s a low-maintenance solution.
- If you consider economic benefits, on-grid power plants are better since you can locally use the power & when there is excess electricity generated, you can export it back to the grid and get reimbursed for it.
- The electricity generated and excess electricity generated, passive income can be used to provide a passive income for residential and commercial users.
- The Return of Investment is as quick as 3-5 years depending the capacity of system installed.
Off grid Solar System
What does this term really mean?
If you are looking for complete energy independence, you should choose an off-grid solar array. This system has no connection to the utility power grid, but it does feature batteries to store the solar energy generated by the system. Solar panels, battery, charge controller, grid box, inverter, mounting structure, and system balance are often included in the system. During the day, the panels store enough sunlight to operate the system, and at night, they utilise the extra power generated.
These systems are self-sustaining and can power essential loads in places where there is no access to a power grid. These systems, however, necessitate specialized equipment and can be pricey to implement. These are perfect for enterprises that can operate without electricity for a limited length of time. Off-grid is also suitable for people who live in remotely, far from power lines.
Applications
Electricity supply in rural and remote locations – Off-grid solar systems can help rural and remote areas generate electricity that is independent, long-term, and sustainable.
Power backup in areas with frequent power outages – A number of locations in India experience regular power outages due to power transmission failures, which can stymie business and government operations.
Cost-effective Solution – Off-grid solar systems can provide a cost-effective and long-term backup solution to the challenges that arise from regular power outages.
Advantages of Off grid Solar System
- These self-sustaining systems are not reliant on the grid and can operate independently.
- The best part about off-grid solar plants is that they produce enough energy to store and utilize at night or when the energy system is down.
- These are ideal for isolated locations where grid electricity is unavailable.
- Your electricity supply will not be affected by grid faults or shutdowns.
So, which one is a better option?
It is entirely up to you to decide which one is suitable for you. Ask yourself these questions before you decide:
1. Does your area experience regular power outages? If yes go Off Grid
2. Does the power outages last less than 30 minutes per day? If yes, go On-Grid
3. Are you ready to incur the additional cost of battery and other DC appliances for your household? If yes go Off Grid
4. Are you looking for standby or partial powering entirely from solar? If yes go Off Grid
5. Are you looking for a more environment-friendly and money option? If yes go On Grid
6. Do you stay in an area away from the city where utility grid is unavailable or unreliable? If yes go Off-Grid
7. Are you looking for install-and-forget system that requires minimal maintenance? If yes go On Grid
And lastly,
8. Do you want to enjoy all modern conveniences – air conditioning, refrigeration, hot water, heating, washing machines, dryers, dishwashers, ovens, etc. and you want to be able to run those things as often and for as long as you want to – and when you want to – at minimal cost? If yes go On Grid.
