Solar Integration: on-grid, off-grid, and hybrid systems

Solar Integration

Using solar energy for companies, heavy machinery units, and homes are becoming popular. There are things that you need to learn first before you go for the solar energy system. There is a whole mechanism through which you can generate energy using solar light.

We will discuss solar energy system and their types. So you can decide which solar energy system you want for your place.

What is a solar energy system?

First, let’s talk about solar energy systems in detail so you will be able to understand this topic in a better way. The generation of energy using sunlight is possible through photovoltaics or concentrated solar power.

The photovoltaic cells will convert sunlight into electric current using the photovoltaic effect. You can generate as much energy as possible, but you will have to get a bigger unit to convert sunlight into electricity. You can generate both heat and energy using the solar energy system.

There are different types of solar energy systems grid, off-grid, and hybrid. Well, you don’t have to get confused because we will discuss every one of them in further detail.

What is solar Integration?

There is a solar energy system that works to provide you with heat and electricity. The solar system is about developing tools and technologies that will provide the solar grid with solar energy. To main the grid efficiency, security, and reliability, a whole system works behind it.

With the perfect design solar system, you can generate a large amount of electricity consumed through the solar system grid.

What does off-the-grid mean?

We have been discussing solar Integration and solar energy systems till now. Then it would help if you also learned about its further details. You might be looking for off-the-grid meaning now. If you have solar panels and you generate a large amount of solar energy, then you might not be able to consume all the energy all at once.

Therefore, an off-grid helps save that surplus solar energy so you can use it later. They work independently, but they will have batteries that will store the energy generated by the solar system.

  • The off-grid solar system consists of a charge controller, solar panels, a battery, a mounting structure, the balance of the system, and another important part inverter.
  • Your utility power will not be connected with an off-grid solar system because it works independently.
  • You will have to connect your utility power system with the off-grid solar system if you want to consume the energy stored in that unit.

So, you might have got an idea about off the grid meaning here. Well, you will learn more about this technology in further detail.

What are off-grid solar power systems?

As we have discussed, the grid meaning above the off-grid solar panel system is the same. It helps you to save the surplus energy generated by solar panels. You won’t be able to use that electricity present in the off-grid solar power system directly. You must first connect your utility power system with that off-grid solar power system.

Off-the-grid solar system works independently. It will help you to store energy only on the spot, but you won’t be able to use it without a connection. So, if you have been looking for off-the-grid meaning, it also means off-grid solar power system.

If you want to set up an off-grid solar system because you know the electricity consumption is lower than the amount your solar panels generate every day, you will require batteries. All the solar energy will get stored in those batteries, so when the sun gets down or doesn’t appear for a day or two, you will be able to run your place with that stored electricity.

Usage of off-grid solar power systems

If you are still looking for off-the-grid meaning, then let’s discuss its usage. You will be able to understand the off-the-grid meaning in a better way:

  • Off-grid solar system for home use. When it comes to home usage of the off-grid solar system, you will require electricity to run your home appliances. You have to get batteries with enough storage capacity to help run your home when the sun gets down.
  • Off-grid solar system for commercial use. The satellite for broadcasting, pumping stations, weather stations, and many other commercial working fields in which off-grid solar systems help run the whole system.

If you compare home and commercial usage of the off-grid solar system, this option solves many problems for commercial businesses.

Pros of off-grid power system

Here are a few benefits of off-grid solar power systems:

1.     Energy independence

You won’t have to depend on the authorities for electricity. You will have a source of energy that you can consume all the time. So, the one benefit of having an off-grid solar power system is that your dependency on the electricity-providing authority will be nonexistent.

So, if you want to use solar energy as your main source of electricity and other power as a backup, then you can go for the off-grid solar system. It will be a great option for your home electricity usage. It will also work for commercial use because you will always have electricity stored in the batteries.

You connect those batteries with your electricity-providing grid to use that stored electricity whenever you run out of it from the main grid.

2.     Electricity for future use

When you get an off-grid solar system, you will always have batteries with stored energy. You can consume it when the sun goes down or doesn’t appear for a few days. The off-grid solar system is the best option if the power generation is more than the consumption.

It will be an independent unit for you to keep storing the energy. It won’t be connected to your power supply system. You can keep storing the energy in the extra batteries and in case of emergency you can easily use that electricity.

Sometimes when the sun doesn’t or doesn’t rise the next day because of the cloudy weather, those independent batteries will help you run your place without facing any problems.

3.     No more running out of electricity

You face a blackout when any fault happens in the main electricity supply if you get it from any authority. There will be no blackout if you are generating your energy through solar panels. Even if the whole city is facing the situation, you will still have electricity at your place.

There will be no more blackouts and running out-of-electricity scenarios. You will keep generating your electricity, and you can store the surplus amount in the independent batteries. Yes, the off-grid solar system will help store the energy, so you will always have a back and don’t have to face the darkness anymore.

Cons of off-grid power system

Here are a few disadvantages of off-grid power systems:

·       Maintenance of batteries

Without maintenance, your batteries won’t work. If you buy any electrical equipment, you will have to do the maintenance work if you want your batteries to run and work.

Most of the time, if you forget about taking care of the batteries, it will only lead to consequences. They might stop working or stop storing energy. Therefore, some people might find this a disadvantage of having an off-grid solar system that they have to keep checking whether everything is working perfectly or not.

·       Batteries shorted lifespan

Batteries for an off-grid solar system that helps store extra energy that your solar panels generally have a shorter lifespan. After 2 or 3 years, they might not show efficiency or stop storing the energy like they used when you bought them.

So, a major con of an off-grid solar power system is that you don’t get a lifetime guarantee of the batteries. They will stop working even if you take care of the maintenance work. Still, you will have to replace them with new batteries if you want the off-grid solar system to work properly.

·       No more backup

What if it’s been weak and the weather is cloudy? You will eventually run out of your off-grid solar panel batteries. You will run out of electricity in this situation. So, you need to consider this con of having an off-grid solar system that, eventually, you will run out of electricity if the weather stays the same.

If you live in a region where the winters are too harsh, and the sun doesn’t appear for days, an off-grid solar system might not be a healthy option. You can keep using the stored amount of electricity from the independent batteries, but you will run out of it, and there will be no backup then. Without backup, you will have to wait for the sun to rise so your solar panels will start generating electricity again.

You will require another electricity backup even if you have an off-grid solar panel system.

What does an on-grid solar power system mean?

A solar system that will get attached to your existing electric grid from you were getting your electricity supply before. Your grid will start getting the same amount of electricity from solar panels.

You can use the amount of electricity generated from the sunlight at your place. The surplus will get stored in the independent batteries. Well, we are talking about an on-grid solar system now, then. It will be your main energy source if you want to get it. You have to be very careful while considering an on-grid solar power system because you might end up blowing up your existing power grid.

An ideal solution for residential homes

Well, an on-grid solar system is the best option for residential use. The electricity consumption in homes will be low compared to commercial areas. Therefore, you can use an on-grid solar system to fulfill your daily life energy needs in your home without worrying about electrical bills.

You will require the solar panel system and install them in the right direction. You will get a surplus amount of energy generated daily.

Pros of on-grid solar power system

Here are a few benefits of on-grid solar power systems:

·       Reduced carbon footprint

Every person has a carbon footprint. That is how much every single person is polluting the environment. The more energy consumption gets added to your carbon footprint, the more you are ruining nature.

To fulfill your requirements, you can work on your carbon footprint by generating energy through a renewable energy resource, sunlight. You won’t be getting electricity from the authorities that burn fossil fuels to provide you with energy. So, using on-grid solar panels will benefit you and the environment.

·       Increase the value of your property

If you get an on-grid solar panel system for your home, it will automatically increase the worth of your property. If you sell your property, you can consider this option because you will get double the amount you invested in those solar panels.

·       Save on utility bills

Once you get the on-grid solar system, you can generate your energy using sunlight. You will be free of your utility bills. You won’t have to pay to govt. For the electricity that you have been using. So, it is a great benefit if you can save money from utility bills for the rest of your life with a one-time investment. Then it is a profitable option.

Cons of on-grid solar power system

The following are the cons of on-grid solar power systems:

·       An expensive energy-generating system

Doubtlessly on-grid solar power system will help you save on electricity bills, but this doesn’t mean that setting up the whole system will be an easy investment. Yes, setting up a solar panel system will cost you a fortune. Later you might be able to save a good amount of money by generating your electricity.

You should know that you will have to make a heavy investment if you want a solar panel system to provide electricity to your whole house. It would be wise to get a quote for the whole solar panel system before you order it. The on-grid solar system cost is going to be quite high.

·       It might not work for your roofs or homes

The on-grid solar panel system is not for every type of roof or home. What if you don’t find the best direction to install solar panels? What if the roofs are too old to handle the weight of the solar panels?

It would help if you considered many reasons before you decide to get an on-grid solar panel system for your home. A big disadvantage of this latest and helpful technology is that it has not been designed ideally for every type of roof and home.

·       Might face a blackout

If you have an on-grid solar power system, what if the sun doesn’t come up for the day, and you run out of electricity? It is a great possibility because if you choose an on-grid solar panel system, you will not have any backup system. This indicates that anything can happen, and you might have to face a blackout.

You will have to get an on-grid solar panel system as well as you will have to think about the backup. So, you will have to invest in two things to never run out of electricity. It will double the amount of your investment in solar panels.

What are solar hybrid inverters?

You get to generate electricity using sunlight with the help of solar panels, but in solar hybrid inverters, you get the option of having another source. Most of the time, you get an option of a photovoltaic system with a PV diesel option. The reason for choosing hybrid inverters is that you never run out of electricity.

Photovoltaic cells and diesel will both generate energy to meet your electricity requirements. Such solar hybrid inverters mixed with PV are also known as diesel gensets.

Usage of solar hybrid inverters

Let’s talk about the usage of solar hybrid inverters in detail:

For manufacturing units

For running a manufacturing unit, hybrid inverters are a good option because you get to generate electricity with the help of sunlight. Plus, you get the backup using diesel to generate energy when the sun goes down. Manufacturing will never have to stop the manufacturing process because you will get electricity all the time.

For homes usage

For homes, hybrid solar inverters are a considerable option because the requirement of running a house won’t be big. You will be able to generate enough energy to fulfill your home requirements regarding electricity. It will help you to get rid of your electricity bills, and you will have to pay for the diesel. In any case, solar panels are not generating electricity.

Pros of solar hybrid inverters

Here are the pros of solar hybrid inverters:

Continuous power supply

You will never run out of electricity if you use solar hybrid inverters. You will always have a backup because if the sun does and the solar panels are not generating electricity, you can generate electricity using diesel. So, there is no way you will ever face any electricity problems.

Low maintenance would be required

The maintenance of hybrid solar inverters is easy, and you don’t have to keep checking the inverter or the batteries connected to the inverter. The hybrid solar inverts have a longer life span, and no maintenance work would be needed to keep the system running.

Cons of solar hybrid inverters

The following are the cons of solar hybrid inverters:

No backup, and a blackout happen

If you run out of solar energy and diesel, you will have to face a blackout. You will require a stable grid if you don’t want to face a blackout. Otherwise, you will surely have to face the darkness if you run out of solar energy and diesel.

High cost to run the hybrid solar inverter

Doubtlessly, you will have a backup of diesel to generate energy and fulfill your energy requirement but running the whole hybrid solar inverter is not going to be a cheap task for you. A high cost would be required to run the system because if your inverter runs out of diesel and the solar panels don’t generate energy for any reason, and you will run out of electricity.

What is a grid tie inverter?

You won’t be able to use DC for your home appliances and other machinery. First, you will have to convert DC into AC to consume it. With the help of a grid tie inverter, it will convert DC into AC, which would be suitable for an electrical power grid. You won’t need any other machinery to convert DC into AC.

Grid tie inverter will do the job for you, and you can consume it from your main grid. Most tie grid inverters are used in wind turbines, electrical power generators, solar panels, and the hydroelectric grid.

How the energy integrates into the solar grid?

You won’t be able to use the energy generated by solar panels directly. You will require a grid where all the solar energy will get stored. You will get energy supply from those solar grids. Now you need to know how you will be able to connect the solar panels to the grid.

Let’s talk about the process step by step:

  • First, you will set up a field of solar panels in the right spot where the sun shines the brightest.
  • The solar panels will convert the sunlight to generate DC electricity.
  • A solar inverter will convert the solar energy into 240 V 50 Hz AC electricity.
  • You will consume the 240V AC electricity to power your appliances
  • The surplus electricity will get stored in the main grid so you can use it later

Final Words:

So, we have discussed the whole solar energy system and integration in detail above. We have also discussed off-the-grid meaning so you can consider getting the system for your place. Solar systems are becoming popular because you can generate electricity free of charge by using sunlight. So, make your decision wisely.
