Various forms of energy are available today. These different energy sources are either renewable or non-renewable. It is an indispensable raw material required by households, businesses and economies. Most of the world still relies on non-renewable energies like natural gas, petroleum, nuclear power, coal, etc. However, most nations are pushing their economies towards renewable energy sources and encouraging businesses and households to move in that direction. In fact, some governments offer incentives for this. Renewable energy sources include energy from wind, hydropower, hydropower, tidal and solar energy. You can find information on the various energy sources here.

Of all of these, solar power remains a popular and easily accessible choice for most people. This makes it a common choice for many households and businesses looking to switch from non-renewable to renewable energy sources. Solar energy is energy obtained from the sun. It's readily available, cheap, and abundant. It's also effective, inexhaustible, and has multiple benefits. That includes it being a clean source and cheap. You don't necessarily need a large capital investment to install it.

Even if the initial costs can be high depending on the size and capacity required, your investments will pay for themselves over time. It also requires little to no maintenance. To use it effectively, it must be converted into electricity or other forms through the use of photovoltaic (PV) panels. These are popularly known as solar panels. Another method of converting the sun into usable energy is concentrated solar energy. You can also use a combination of the two methods.

What are solar panels?

Solar panels are essentially used to convert energy from the sun into electricity. Sunlight is made up of particles of energy called photons. By using a photovoltaic module, these photons can be used to generate electricity, which is then used to operate electrical devices. These panels are useful for a variety of applications such as telecommunications equipment, remote power systems, and remote sensing. They are ideal for supplying power to commercial and residential buildings.

Edmond Becquerel, a French physicist, discovered the "photovoltaic effect" in 1839 and that is the principle according to which solar panels work. The photovoltaic effect enables sunlight to be converted into electricity when electrodes coated with silver chloride or bromide are illuminated. Charles Fritts improved this in the manufacture of the first solar cell by coating selenium sheets with thin layers of gold. This eventually led to what is now known as solar panels. However, the first panel was made by Bell Laboratories through the invention of American inventor Russel Ohl. These panels were first used in space satellites and later embedded in calculators. Today they are used for many other applications. You can learn more about their history by reading this article.

How do you work?

A solar panel consists of various individual solar cells that are composed of layers of phosphor, silicon and boron. While phosphorus provides the negative charge, boron provides the positive charge. This allows the plates to absorb photons that come in from sunlight. The photons initiate an electric current. This energy generated by the photons enables the electrons to be removed from their atomic trajectory. They are then released into the electric field generated by the solar cells and drawn into a directed current. This process is known as the photovoltaic effect.

Typically these panels are installed on the roofs of buildings. The average building has enough space to hold the number of panels needed to power such a building. They can also be installed on a plot of land next to or near the building. Excess electricity can be supplied to others or fed into the national grid. In a symmetrical grid-connected arrangement, the panels generate electricity during the day, which is used at night. Depending on your location, you might get paid if your solar system produces more electricity than you need.

In an off-grid system, some of this energy can be stored in batteries and used at a later point in time. To do this, you need a charge controller and an inverter. The solar system supplies the battery with direct current via the charge controller. The inverter converts this into locally usable alternating current.

Installation of solar panels

Now you know about solar panels and how they work. Then how do you buy and install for your residential or commercial space? There are several brands out there, but you don't need to worry that much. What you need to do is reach out to suppliers and installers to help you with your installation. Installers can advise you on the best panels to install and where to install them. You can visit your Solar Spot for help finding the right installers. However, find out what the costs will be before installing. You may be able to get funding, tax breaks, and incentives. Also, be sure to check if you need a permit to install in your city.


Using renewable energy sources such as solar energy has several advantages. Besides being inexhaustible, it's cheap, clean, and low-maintenance. Usually you need a one-time installation. Additionally, you may even be able to get paid for excess electricity and receive tax rebates and other incentives. All you have to do is install high quality and durable solar panels to enjoy all of these benefits.
