Solar energy starts from the sun. Solar panels (also called “photovoltaic panels”) convert sunlight, which is made up of “photons”, into electricity that is used to transport electricity.

Solar panels can be used for a variety of applications including remote power systems for homes, telecommunications equipment,  and of course to generate electricity from residential and commercial electrical systems.

The development of the solar panel dates back to more than 100 years. Originally, solar energy was used to generate steam, which could be used to power machinery. But until the discovery of the “photovoltaic effect”, which will allow the conversion of sunlight into electricity. This led to the creation of the first solar cells, which were created by coating selenium with a thin layer of gold. And that gave birth to the device we know today as a solar panel.


A photovoltaic cell receives energy from photons when sunlight falls on a semiconductor, leaving many electrons floating around the cell. The positive and negative semiconductors of a solar cell are placed in a certain way to generate electricity (Source). This electric current forces the metal conductor plates inside the cell to accommodate the movement of electrons in one direction. The amount of electricity produced by each cell depends on the strength of this system, which is called current strength. Electricity is then sent through the wires as the free electrons hit the metal plate, allowing the electrons to flow. The electrical energy from the sky goes through the wires to the inverter. Although solar panels produce direct current (DC), many electricity consumers require alternative electricity (AC) to power their systems. Energy flows when solar panels generate electricity. Once it is changed to the state of use, the electric panel receives electricity from the inverter and distributes it in the house as needed. Today, solar energy is used to control lights, appliances and other electrical devices.


Going solar is quite exciting. You can save a lot of money on your energy bills as you do your part to go green. But deciding which type of solar panel to choose can be tricky. Use this quick guide to help you choose the best material for your home.


Also sometimes referred to as Mono-Si or monocrystalline silicon, monocrystalline silicon solar panels are the most common . They are made by adding a crystalline seed that makes the silicon hard, it is shaped into a panel and cut into the holes that make up the panel. The result is high quality, with a flexible crystal structure that improves the performance of the panels. The bars usually have cells with the corners cut off, which gives them a shape. The benefits of these panels include:

  • It requires the least amount of space as compared to other types of solar panels.
  • They’re the most durable and usually come with a 25-year warranty.


Commonly called p-Si or multicrystalline silicon, polycrystalline silicon solar panels are made by melting raw silicon. This is poured into a suitable material before it is cut into a perfect square, giving these panels a different look to their Mono-Si counterparts. Because the process is simple, these solar panels are also affordable. Solar efficiency ranges from 13 to 16 percent on average. Moreover they take more space.


Thin solar films are produced differently than other types of panels. They are made by supporting photovoltaic materials such as cadmium telluride, organic photovoltaic cells, amorphous silicon or indium copper. Depending on the type of material used, the efficiency of this type of panel can be as high as around 13%, according to Energy Informative. Because they are easy to manufacture, they are often inexpensive. In addition, they have a uniform appearance that many owners find attractive. They take up a lot of space, so they don’t always fit perfectly.


The latest solar panel technology, multi-junction solar, offers about 40% efficiency. Different types of solar panels are produced, with levels of semiconductors, each of which can convert light into different energies to consume less light and provide more energy. Although they are very effective, they are also very expensive. These solar panels are usually used only in research laboratories and satellites.


Confused about how to choose the right solar panel for your home? You are not alone. But these tips can make the shopping process easier.

·        Output: Calculate the amount of electricity you use each day to determine the wattage you need from your solar panel.

·        Space: If you have a ton of free space to install your panel, you may want to be more organized. But if you are short on space, you can compromise by choosing a small configuration or expensive monocrystalline silicon panels, which provide maximum performance and minimum space.

·        Budget: You can use the dollar per watt calculator to determine how much you will spend to power your home. Most experts recommend looking for a space around $4 per watt. For example, if you choose a panel with a maximum power of 200 watts, it will cost you around $800.
