The conversion to solar power has been one of the simplest methods to save on electricity costs and limit reliance on the old sources of power. However, when you are not familiar with solar technology, the Off-grid and on-grid may be confusing. This guide has simplified both of the systems down to language that you can easily understand how they work and which one is more appropriate to your needs.

On-grid Solar System

A grid-tied system also known as an on-grid solar system is one that is directly linked with the main electricity grid. This is the general arrangement of homes and business buildings.

How It Works

1. Solar panels produce electricity when the sun rays fall on these panels.

2. This energy is directed to the solar inverter that transforms DC equally to the useful AC power.

3. This electricity is used at home first.

4. The power that you have more than you require is sent back to the grid by your panels.

5. This is credited to you with the net metering which lowers your electrical bill.

Best For

1. Regions that have constant grid supply.

2. Houses and offices that want to reduce bills.

3. Those who do not have to have power backup.

On-grid systems tend to be cheaper as compared to off-grid systems since it does not come with batteries.

Off-grid solar system

An off-grid solar system operates on its own without having any contact with the main grid. It stores the surplus solar energy in batteries such that electricity would be there even in the dark or when there is power outage.

How It Works

1. The sun’s energy is captured with the help of solar panels and converts it into DC power.

2. A charge controller ensures the safety of the batteries as it stores the energy.

3. The DC power stored is then converted into the AC power by use of inverter.

4. On sunny days or when there is too much demand of power, power is used under battery-stored power.

Best For

1. Out of grid remote places.

2. The houses with long or frequent power outages.

3. Users with the desire to be energy independent.

Off-grid systems are expensive due to the use of battery storage and reliability where there is none with the grid.

The On-Grid /Off-Grid dilemma: Which one is better?

The selection between the two will depend on the place of location, budget and backup requirement. An on-grid system suits perfectly in case you want to trim bills of electricity and you have a constant power supply. An off-grid system is more preferable in case you require continuous power or you live in a region where you do not have much access to the grids.

Conclusion

Solar energy is emerging as a viable option to houses and companies in India. In case you have some plans to dive into the world of solar or just want to learn how various systems operate, companies such as Solar India still provide access to clean energy with the help of reliable products that may meet different requirements.
