How Many Solar Systems Are There?

Solar systems and photovoltaic cells change the contemporary idea of electricity consumption. This process helps people reduce costs and save the environment with eco-friendly technology

Besides, the solar system enhances the possibility of energy supply to remote areas of the world. 

In several countries, the government offers some benefits for solar energy users. 

There are grid-tied, off-grid, and hybrid solar systems depending on the technology and using habits. Let’s explore each system and its working patterns. 

Grid-tied solar

The most innovative idea that allows users to maintain their electricity consumption. A grid-tied system is directly connected to traditional electricity and solar panels. 

The user can select and maintain the power source depending on needs and production. When a homeowner needs more power than the solar system produces, he can use the extra energy from the grid. 

Similarly, the homeowner can send the extra energy from the solar system to the grid. It enables you to sell additional energy from your solar system that you don’t use. 

Switching and transferring the energy system, you can save a lot and earn some extra when your system sends energy to the grid.

This process ensures efficient power management and adequate energy supply when you need more. 

You can also use batteries to store the additional energy for further use with this system. 

Grid-tied systems are now more popular in developed countries. It reduces the upcoming energy demand on the national grid.

Off-grid solar

This is the route idea of solar technology. In this system, solar panels will produce power and send it to the system. 

You can convert the power to Alternative Current (AC) or use it directly for DC appliances. 

It doesn’t require a traditional electricity connection. It is a completely independent system that will give you more comfort for energy production.

If you install an off-grid solar system, you need to connect batteries for power storage. The sun can provide power during the day, and the battery will provide power at night.

This system is famous around the world. People get electricity from off-grid solar systems where the grid is unavailable. 

Hybrid Solar

A hybrid solar system is similar to the grid-tied, and it is used with a battery. A hybrid inverter is used to store power in the battery. 

It supports you to use the solar system when the sun is unavailable. Besides, the system will enable you to access electricity like a UPS system.

The name hybrid comes because of the combination of solar systems and batteries. This system can interact with the grid, battery, and solar.

Rooftop Solar System

Rooftop Solar System

A rooftop solar system is the most used solar panel for residential purposes. In this system, you can utilize the space of your roof to generate electricity. 

It has several advantages, and you will get an independent energy source without covering the free space of your home.

The most important fact is that solar panels get sufficient sunlight from the sun all day long in this system.

Rooftop Solar System Components

A solar system in which solar panels are installed on the roof of the building or house is called a rooftop solar system. 

This system saves space and costs more than other installing options. You need several items to install a rooftop solar system. 

Here, we present the description, types, and process of installing these components to give you a clear idea. 

Solar Panel

A solar panel is a combination of solar cells that converts sunlight into electricity. In your rooftop solar system, you have to install solar panels on the roof where adequate sunlight is available all day long.

Solar panels do not require the heat of the sun but require sunlight. You will get Direct Current (DC) from the solar panel. 

You have to convert this electricity to Alternative Current (AC) to run devices and appliances. 

The panels will be installed on a rooftop with an especially created structure. The structure will hold the panel in any weather condition.

There are several types of solar panels categorized based on the types of solar cells. 

The most used solar cells are monocrystalline and polycrystalline. You can select a solar panel depending on your power needs. 

These panels are manufactured in different wattages and sizes. It is better to select a powerful solar panel that comes with a small size/ 

Besides, solar panels can work in any weather condition, and they are waterproof. You can use a high-quality solar panel for at least 20 years. 

You have to consider the efficiency of the solar panel before installing it on the rooftop. Good solar panels come with 20 to 30 percent efficiency on average.

So, you need to find the best solar panel for reliable power production.


The inverter is an important component of a solar system. You have to use an inverter whether you are using a ground or rooftop solar system. 

Solar panels convert sunlight to energy and send them to the solar system. An inverter makes this energy suitable to use for your devices. 

It also maintains the voltage and recharges the battery with a perfect energy flow. Several types of inverters convert electricity depending on your needs. 

Before selecting a solar inverter, you have to choose the electricity output pattern and solar system type.

There are three types of solar inverter: Grid-tied, off-grid, and hybrid. 

Grid-tied Inverter

These inverters are designed for grid-tied solar systems where you need to send the electricity to the grid and battery.

A grid-tied inverter shuts down the system when there is no electricity from the grid and turns on the battery power for backup. It also helps the system maintain power sources between the grid and the solar panel. 

Off-grid Inverter

This inverter works for solar systems where the grid is unavailable and not connected with the system. It mainly maintains the battery charging and power the off-grid appliances directly from the solar or battery.

You can use Alternative or Direct Current output inverters based on your needs. 

Hybrid Inverter

It is a complete power solution inverter with MPPT, DC-AC converters, and anti-islanding features. Hybrid inverters are the most reliable inverter if you use a different power source for your solar system.

Mounting Structure 

After purchasing solar panels and inverters, you have to develop a mounting structure on the rooftop. In general, solar panels are installed with iron structures so that they can perform for a long time. 

Solar panels need sunlight from the morning to the evening, and a south-facing installation frame enables them to get adequate sunlight.

Besides, you have to prepare the rooftop area where you will install the mounting frame. The solar panel will work here for at least 20 years. 

You can not clean the place as before, and it can be harmful to long-term usage. You have to prepare the place with a special coating and cementing to stop damage.

The place should be clean and have adequate air circulation. It will get excessive heat during the summer. Sufficient air and rain will maintain the temperature. 

Wire and Tools

You can not install solar systems without the necessary tools. Similarly, connection cables will connect the solar panel, inverter, battery, and device. So, you have to prepare these things when starting installation.

You need different solar panels, structures, wiring, and battery installation tools. 


Grid-tied solar systems are not available in all countries, and they use off-grid solar systems. A battery will provide power at night when the sun is unavailable.

So, the battery is an important component of rooftop solar systems.

Other Components

You need other components when installing a solar system. These are the necessary things that require minor maintenance during the operation.

You got the idea about rooftop solar systems, types of solar panels, and necessary components to install a solar system. 

Now, you have to install the system with the right steps to make it successful. A wrong decision can make your solar system faulty. Your solar system can not produce sufficient energy with a faulty installation process. 

So, you have to decide whether you will install the solar panel or hire a professional for the work.

We suggest hiring a professional when installing a large solar system with several solar panels, batteries, and devices. 

On the contrary, if you are installing a small and low-power solar panel for temporary backup, you can do it by yourself

Can You Install A Rooftop Solar System?

You can only install a solar system perfectly when you have proper training. Otherwise, it is better to hire a professional to install your solar panel. The installation process could go wrong, and that creates several problems. Here is some example: 

Wiring Problem

A solar panel is connected to several types of electrical equipment, and it requires wiring. The wiring system should be perfect and error-free. Otherwise, it creates short electrical circuits that might harm human beings and devices. 

Leaky Roof

You will install a solar panel on the top of your roof. This installation process requires creating several holes on the roof. A professional installer uses proper tools and processes to do this.

If you are not experienced in this sector, you can’t do it. Without proper and strong sealing, your roof will be leaky. 

Safety Standard

A professional installer knows the safety standard of rooftop solar panels. It is difficult to maintain the process when you do it by yourself, and the officials will reject the system.

Installer’s Safety

Solar panel installers mainly work with professional contractors, and they are equipped with all the necessary tools. They know the steps very well and keep them safe when installing solar systems.

Hiring A Professional Installer

If you don’t want to install solar panels yourself, you can hire a professional installer. It will be better than the do-it-yourself process, and the system will work perfectly. 

A professional installer receives training and knows everything according to the safety standard. Besides, the person has all the necessary equipment for rooftop solar panel installation. 

In this process, the installer mainly follows a pre-inspection process to make the project successful and time-consuming.

Rooftop Solar System Alternatives

Rooftop Solar System Alternatives

If you are not willing to install solar panels on your rooftop, you can select an alternative to this system. 

These alternatives are perfect for people who don’t have a traditional and spacious roof. Besides, you can not make your rooftop solar system portable. 

So, it depends on your needs whether you will use a rooftop solar system or another option.

Here, we present the most effective alternatives to rooftop solar systems. 

Ground System

We have a common idea regarding the solar system. Most people think that solar panels are only suitable to install on rooftops. 

The reason behind this idea is people’s visualization of solar panels on the top of houses and buildings.

But, you can install solar panels on the ground when there is not enough space on the roof. It allows you to install large amounts of solar panels without increasing the damaging roof risk.

Besides, you will get easy access to solar panels for maintenance and cleaning. Though solar panels don’t require special maintenance and cleaning, they will help you keep the panel safe.

If you want to know how to clean a solar panel the right way, you can go here.

But there are some limitations of the ground solar system. For instance, you can not use the place for other purposes. 

Solar panels can’t produce sufficient energy if there is shade. So, you have to install solar panels separately in a parallel series. These panels will cover a huge space. 

Furthermore, it can be damaged by animals and pets when installed in an open space.

Considering all the issues, ground solar systems and rooftop solar systems are the same. The only difference is the place where solar panels will be kept.

Portable On Ground Solar System

This is the best alternative if you want to use solar energy in different places. You can select the portable solar system.

In this system, you can use portable solar panels and inverter systems that can be carried anywhere according to your needs.

This on-the-go solar system allows you to get instant electricity without too much cost and time. It will help to run your devices during power cuts and natural calamities.

A portable solar panel is also suitable for outdoor parties, camping, and hiking. You can install it within a very short time and remove it quickly. 

The system saves your time and allows you to run outdoor gadgets without increasing the electricity bills. 

There are some limitations of the portable solar system. You can not run lots of appliances on this system. It can generate less power because of its low power production capacity.

Otherwise, it is okay for a day trip or a family party where you need a certain amount of electricity for a few hours. 

Wrapping Up

Finally, you got the description of the rooftop solar system and its installation process. Now, you can install it or go for the alternatives. 

It is better to follow the installation process properly to make the system efficient and secure. 

You will invest in a solar system once and get the benefits for at least twenty years. So, you have to select the best devices, systems, and processes.

At the same time, you need to consider your necessity and the location of your home. Selecting a solar system that fits most of your needs will give you efficient output and a convenient user experience.
