How On Grid Solar System Works?

How On Grid Solar System Works
How does on-grid solar power system works? – The arrangement of solar modules absorbs the sunlight on them and convert them into electricity. The current generated here is Direct Current (DC). The solar inverter then converts the DC to Alternating Current (AC), thus making it power the electrical items.

How does solar power work with the grid?

A grid-tied home solar system is one that remains connected to the electrical grid. Such a system generates power for the home and it feeds any excess power it generates into the grid. The amount of power it feeds into the grid can slow down the home’s electric meter as it measures usage.

What is the disadvantage of on-grid solar system?

Disadvantages of on-grid systems –

  • On-grid solar systems are battery-less and therefore not able to function or generate electricity during a blackout, due to safety reasons. As blackouts usually occur when the electricity grid is damaged – if the solar inverter was still feeding electricity into a damaged grid it would risk the safety of the people repairing the fault/s in the network.
  • They can’t produce solar energy and reduce your power bill at night-time or when there’s no sunlight.
  • They provide you with less incentive to conserve energy!

Can on-grid solar system work without electricity?

To make the right choice it is important to comprehend the key differences between off-grid and on-grid solar systems. – How On Grid Solar System Works Team ProductLine With the increasing costs of power and electricity, a number of businesses are shifting to solar power systems. The Ministry of New and Renewable Energy (MNRE), Government of India is also encouraging solar PV systems for businesses under its Jawaharlal Nehru National Solar Mission.

India is ranked second among emerging economies to lead towards a transition to clean energy, according to a 2018 report by Climatescope. Commercial and industrial buildings in India, which are supplied grid electricity at significantly higher rates than residential users, find switching to solar systems more economical.

While making a decision to shift to solar power systems a number of businesses get confused between off-grid and on-grid solar systems. To make the right choice it is important to comprehend the key differences between off-grid and on-grid solar systems.

On-grid solar systems On-grid solar power systems generate power using a solar power system and are directly connected to the utility power grid. These systems send excess power generated by the solar power system to the utility grid and consumers get compensated for the extra power fed back. These systems work in collaboration with the power grid.

In the case when there is not enough sunlight to meet your business’ needs, the system runs on the power supplied by the grid. These systems are best suitable when your power consumption is high and you wish to reduce your electricity bills. On-grid systems can be installed with or without net metering.

Being connected to the main grid, these systems do not work during power outages. Applications: Businesses can rely on on-grid solar systems to meet their daily requirements, as well as earn income from the excess power generated. On bright sunny days, buildings can generate enough solar energy to power appliances, lights, water heating systems, etc.

On-grid solar systems are very cost-effective and easy to install. Businesses can recoup the cost of their investment by offsetting electricity bills in just 3-8 years. If a private, commercial or industrial building sets up a solar PV rooftop system it will be eligible to avail an ‘Accelerated Depreciation Benefit’ which is currently 80% in a year. At this rate, a business can completely depreciate the whole value of the project in approximately 4 years. Residential users and business owners can earn a passive income for the surplus energy generated by the system.

Off-grid Solar systems Off-grid systems work independently of the grid but have batteries which can store the solar power generated by the system. The system usually consists of solar panels, battery, charge controller, grid box, inverter, mounting structure and balance of systems.

The panels store enough sunlight during the day and use the excess power generated in the night. These systems are self-sustaining and can provide power for critical loads in areas where a power grid is not available. However, these systems require specialized equipment to function and can be costly to install.

These are ideal for businesses which can sustain for a short period of time with no electricity. Applications

Electricity supply in rural and remote areas – Off-grid solar systems can facilitate independent, long-term and sustainable electricity generation in rural and remote areas. Power back up in areas with frequent electricity cuts – A number of places in India face frequent power cuts due to power transmission malfunctions, which can hamper operations of companies and public institutions. Off-grid solar systems can provide an economical and viable long-term backup solution to overcome the problems occurring during frequent power cuts.


These self-sustainable systems can work independently and do not rely on the grid. They generate enough power that can be stored and used at night or when the power grid is down. These are ideal for remote areas where there is no power access from the grid. Grid failures and shutdowns will not affect your power supply.

Electricity consumption in India is forecasted to reach 15280 TWh by 2040. The Indian government has set a target of reaching a renewable energy generation capacity of 225 GW by 2022 and is offering a number of benefits as well as tax rebates to businesses which shift to renewable solar energy systems.

Solar power systems are a source of clean renewable energy and have numerous benefits depending on the type of system you choose. Due to a drop in the prices of solar PV in the last few years as well as significant policy-level implementations by the Government of India, setting up solar PV technology systems in residential buildings and business organizations have become very lucrative.

Commercial and industrial buildings that source grid electricity at higher rates from power utilities are now weighing options to offset the cost. However, a common dilemma is whether to connect to an off-grid or on-grid solar power system. Before making the choice, here’s a look at the difference between the two systems On-grid systems On-grid system is the one in which solar power system is connected to the utility’s power grid.

  1. The excess power generated is sent to the utility grid and the consumer gets compensated for it.
  2. Similarly, when the system underproduces power, the consumer can draw electricity from the grid and pay for the units used.
  3. Being tied to a grid is beneficial as the consumer does not need to buy an expensive battery backup to store excess energy.

This makes on-grid systems more popular in residential spaces. Businesses also use the system to meet their daily requirement and earn income from the excess power generated. However, being connected to the grid means the consumer may have to face power outages.

A consumer can use net metering for on-grid systems. Also Read: According to the Ministry of New and Renewable Energy, the government targets to install 100 GW grid-connected solar power system by 2022. To achieve the target, the Centre has launched schemes and undertaken several policy measures to encourage use of solar power systems such as Solar Park Scheme, VGF Schemes and Grid-Connected Solar Rooftop Scheme.

As a result, the cumulative capacity of grid-connected solar power projects has increased from 932 MW in 2011-12 to 6762.87 MW in 2015-16 and 28180.68 MW in 2018-19. Why one should choose on-grid systems? Easy to install, cost-effective Offer residential users and businesses the opportunity to earn passive income from surplus energy produced by the systems Private, commercial or industrial buildings can avail of ‘Accelerated Depreciation Benefit’ by setting up PV rooftop systems, which is currently 80 percent in a year, according to an Economic Times report.

  • Off-grid systems Being off-grid means the system works independently and the consumer is not connected to any utility’s power system.
  • This system uses batteries to store generated solar power.
  • Although off-grid systems are self-sustaining, they involve higher expenses as the consumer has to buy a battery pack, solar panels, grid box, inverter, charge controller, mounting structure and balance of systems.

The panels generate and store power during the day and use it at night. The system is ideal for places that suffer frequent power outages. In rural and remote areas, off-grid solar systems can facilitate independent and sustainable electricity generation.

One of the oldest programmes under the Ministry of New and Renewable Energy is the Off-grid Solar PV Applications Programme through which the ministry has set up solar home lighting systems, solar street lighting systems, solar lanterns, solar pumps and solar study lamps. Also Read | According to the ministry website, solar pumps are an important component of the solar off-grid programme which gives small and marginal farmers a reliable irrigation facility.

How much does solar contribute to the grid?

Solar power is more affordable, accessible, and prevalent in the United States than ever before. From just 0.34 GW in 2008, U.S. solar power capacity has grown to an estimated 97.2 gigawatts (GW) today. This is enough to power the equivalent of 18 million average American homes.

Today, over 3% of U.S. electricity comes from solar energy in the form of solar photovoltaics (PV) and concentrating solar-thermal power (CSP), Since 2014, the average cost of solar PV panels has dropped nearly 70%, Markets for solar energy are maturing rapidly around the country since solar electricity is now economically competitive with conventional energy sources in most states.

Solar’s abundance and potential throughout the United States is staggering: PV panels on just 22,000 square miles of the nation’s total land area – about the size of Lake Michigan – could supply enough electricity to power the entire United States, Solar panels can also be installed on rooftops with essentially no land use impacts, and it is projected that more than one in seven U.S.

homes will have a rooftop solar PV system by 2030. CSP is another method for capturing energy from the sun, with about 1.8 GW of capacity in the United States. The cost of electricity from CSP plants fell more than 50% from 2010 to 2020. If CSP cost reduction targets are met, studies show it could provide up to 158 GW of power to the U.S.

by 2050. Moreover, the solar industry is a proven incubator for job growth throughout the nation. American solar jobs have increased 167% over the past decade, which is five times faster than the overall job growth rate in the U.S. economy. There are more than 250,000 solar workers in the United States in fields spanning manufacturing, installation, project development, trade, distribution, and more.

Solar energy hasn’t reached its full potential as a clean energy source for the United States, and significant work remains to be done to drive deployment of solar technologies. Solar hardware costs have fallen dramatically, but market barriers and grid integration challenges continue to hinder greater deployment.

Non-hardware solar ” soft costs “—such as permitting, financing, and customer acquisition—are becoming an increasingly larger fraction of the total cost of solar and now constitute up to 65% of the cost of a residential PV system, Technological advances and innovative market solutions are still needed to increase efficiency, drive down costs, and enable utilities to rely on solar for baseload power.

How much does it cost to connect solar to the grid?

Grid-Tied Solar System Cost – The average cost of a grid-tied solar system is between $15,000 and $21,000, This system ranges in size greatly. The idea is that you reduce your dependency on the power grid but not completely eliminate it. Therefore, you can reduce your needs by a little or a lot.
