Did you know that, following the Union Budget 2024, India’s renewable energy sector is expected to reach 500 GW by 2030, growing more efficiently than ever? According to recent research by CRISIL, the sector has already seen impressive growth, jumping from 72 GW in FY20 to 97 GW in FY22, with projections estimating a rise to 180 GW by FY26.

Solar power is no longer just a trend—it’s the smart choice for many. Choosing the right solar system can be challenging if you are unaware of the workings of the on grid and off grid systems. Let’s delve into the nuances with this blog, which will serve as your ultimate guide to understanding the differences between on-grid and off-grid solar systems.

What distinguishes an off-grid solar system from an on-grid solar system?

When selecting the right type of solar system for you, it's critical to fully comprehend the differences between on-grid and off-grid systems and to carefully consider your particular needs and situation.

On Grid Solar Systems

On grid solar systems is connected to the GRID of your local utility. This is the most commonly used in residential as it protects you from the energy fluctuations of over or under-production of the solar system. This means that your utility system serves as your battery.

If your solar panels or system generate more energy than you need, the extra energy is transferred to your grid's power provider, enabling you to accrue credit that you may pay out at the end of the year. This procedure is called net metering. These credits are stored in your account with the utility company and can be used to offset the cost of electricity you consume from the grid when your solar panels aren’t producing enough, such as during nighttime or cloudy days. This way you can balance your energy usage and maximize the benefits of your solar system.

One advantage of being grid-tied is that it eliminates the need to purchase a costly battery backup system in order to store extra electricity. Based on your utility's billing cycle, you may either:

- Cash out your accumulated credits throughout the year, or

- Roll over the credits to the following year to balance the future electricity usage.

On-Grid Solar System Components:

- Solar Panels are the main drivers of a solar system. They absorb sunlight and convert it into electricity.

- Inverter converts the DC electricity from the solar panels into AC electricity for household use.

- Meter tracks how much electricity you use and how much you send back to the grid (for net metering).

- Utility Grid Connection allows the excess energy to be fed back to the grid and draws power when solar energy is insufficient.

- Breaker Panel distributes electricity to different parts of your home.

On-grid Solar Systems Advantages:

On-grid solar systems are connected to the local utility grid allows extra solar energy to be sent back to the grid, giving you cost-effective electricity.

Through net metering, you can sell surplus electricity to the utility provider which enables you to earn credits and thus gives you an opportunity to earn money.

Solar systems are reliable as they store excess electricity generated to be used when solar energy is low, like at night or on cloudy days.

On-grid systems are more affordable and cost-effective because you don’t need expensive batteries for storage of the excess electricity.

They also help the environment by reducing reliance on fossil fuels, as excess solar energy is shared with others on the grid, making it a sustainable choice.

Off Grid Solar Systems

Off grid solar systems have no connection to the utility company or electrical grid. It generates energy from solar energy and stores the access energy in the batteries to be used later when sunlight is unavailable. There are certain drawbacks, off-grid systems necessitate the purchase of backup batteries, which can be costly, large, and unfriendly to the environment, negating the goal of switching to solar power.

An off-grid solar system consists of solar panels that capture sunlight, a charge controller to manage energy flow, and a battery bank to store extra power for later use. The inverter then converts stored energy into electricity for your home. If needed, a backup generator can provide additional power during long periods of cloudy weather.

Off-Grid Solar System Components:

- Solar Panels capture sunlight and generate electricity.

- Inverterconverts DC electricity from the solar panels and batteries into AC electricity for home use.

- Charge Controller regulates the flow of electricity from the panels to the battery bank to prevent overcharging.

- Battery Bank stores excess energy for use during the night or cloudy days when the system isn’t generating power.

Off-grid Solar Systems Advantages:

You can be energy independent as solar energy is not dependent on the utility grid. These systems rely on batteries to store the excess energy for a rainy day.

Remote locations which have less access to the main utility grid, is an ideal place to install the off grid systems.

It is cost-effective as you can save money in the long term by not relying on the utility grid bills.

In adverse conditions like grid outages or natural disasters, off grid solar systems are resilient and can maintain the flow of electricity throughout.

Factors to be taken into account before finalizing the solar systems:

Location:Think about the climate where your business is located and how much direct sunlight it gets.

Power Needs:Estimate your current energy usage to determine the right size and type for your solar system.

Budget:Take into account both the upfront costs and the long-term savings of what you can expect from the system.

Grid Reliability:Look into the stability of the power supply in your area to see if you need a system that can function independently.

Government Incentives:Research any available incentives or subsidies that could help reduce your initial investment.
