What is solar panel and how it works?
Solar Panel is also known as Photovoltaic Solar Panel, made using smaller units of silicon. This is called a solar cell, which converts solar energy into electrical energy. Silicon is a semiconductor inserted between conductive layers in a solar cell.
How solar panels work? The process of solar paneling starts during the day time when proper sunlight is there. The sun rays fall on Solar PV Panels that are installed on your rooftop, and photovoltaic refers to the scientific process by which solar energy gets converted into electrical energy.
There are several silicon cells within each PV panel, and these cells react with photons (unit of light), which come from the sun to produce DC (Direct Current) or electricity. The direct current (DC) then travels into an inverter that converts it into AC (Alternating Current), which further used in your home, office, playgrounds and many other places. After this, AC current transfers to the distribution network in your home, which is capable of powering electrical appliances of your house. When Solar Panels produce more electricity than your home is using, the extra electricity gets shifted or stored in the grid. And, you can avail of the benefits for the extra electricity that your solar panels generate. Moreover, solar panels are available in different sizes and price ranges.

Working Principle of Solar Panels
Solar Panels work on the principle of the photovoltaic effect, which is a method of producing direct current electricity based on the principle of the photoelectric effect. Photovoltaic directly converts solar energy (sunlight) into electricity. When certain materials expose to sunlight they absorb photons and then release free electrons, and this phenomenon is called the photoelectric effect.
Solar cells or photovoltaic cells are used to convert sunlight into direct current (DC) electricity. Though a single photovoltaic cell does not produce enough amount of electricity, hence several photovoltaic cells are mounted on a supporting frame and electrically connected to form a photovoltaic module or solar panel. The current or electricity that solar panel system provide is dependent on the effectiveness of sun rays.
Types of Solar Panels
Solar Panels are classified into two types such as Monocrystalline Solar Panels and Polycrystalline Solar Panels.
Monocrystalline Solar Panels:
Monocrystalline Solar Panels are made using extremely pure mono (single) silicon crystal that helps in converting solar energy into electricity. Monocrystalline solar panels are suitable for easy installation in smaller areas, which requires a reasonable price. However, the monocrystalline solar panel installation is ideal for a larger area, but it makes it expensive. Users will be able to get the most electricity output according to the monocrystalline panels used.
Polycrystalline Solar Panels:
Polycrystalline solar panels are made using poly (multiple) silicon crystals and known as the most commonly used type due to price and efficiency. The cells used in Polycrystalline are a small amount of quantity that makes the Polycrystalline Solar Panels a bit less efficient. For this reason, users can install a large number of polycrystalline panels to generate electricity to meet their consumption needs. As compared to Monocrystalline Solar Panel, Polycrystalline Solar Panel is considered the commonly used type as they maintain a good balance between pricing and effectiveness.
Difference between Monocrystalline and Polycrystalline Solar Panel
The difference between Monocrystalline and Polycrystalline solar panels is the advanced technology that has made them practically interchangeable. Owing to the manufacturing process and robust technology, Monocrystalline Panels are quite expensive as compare to Polycrystalline Panels. The monocrystalline solar panel comes with black and dark blue color, whereas polycrystalline panel appears in the blue mottled.
Monocrystalline Solar Panels are more efficient than polycrystalline solar panels thus, you can use slightly more power in the same size and space of monocrystalline panels. But polycrystalline panels need more equipment to produce the same amount of electrical energy as monocrystalline. For this reason, the solar panel cost is less for polycrystalline. Interested buyers can purchase any solar panel through online and also by visiting stores.
When it comes to temperature, Monocrystalline panels handle the heat slightly better than polycrystalline solar panels. This temperature difference can be noticeable especially in extremely hot areas such as deserts, as compared to residential regions. Last but not least, monocrystalline can perform in a better way even on hazy skies than polycrystalline panels.
Solar Inverter is an indispensable device used in any solar power system utilizing sunlight or solar energy. A solar inverter is useful in changing the DC (Direct Current) into AC (Alternating Current) using solar power. In other words, the solar inverter is used to change the variable Direct Current (DC) output of the solar products into Alternating Current (AC). And this AC power is pushed into your home to operate your appliances, be it a bulb, fan, or home system.
A solar inverter is just an inverter operated using energy from the sun, which helps several devices working by DC power to run them on AC power. In this way, the consumers can use AC power to operate their required piece of equipment. One can ask why to use Solar Inverter instead of using a normal electric one. The answer is simple - solar inverter makes use of solar energy or sunlight, which is clean and pollution-free.
