How is Solar Energy Produced?

The Sun lies at the heart of our solar system. It is the largest celestial body in our entire solar system. But do you know that everyday when sun shines, it delivers around 3 trillion watts of energy to the earth? This single day’s energy is more than enough to power at least 3 million homes for a whole year! Ever wondered why do we not make use of this free energy source which is available in abundance? The reason behind this is lack of proper knowledge and often lack of awareness of how solar works. Infact, there are certain myths associated with the solar energy which adds to this woe. Some of the myths includes that solar is very costly and doesn’t really fit into the pocket of a common man. Little do you realise that there are lucrative financial schemes available.

So, without taking much of your time let us get into details and explain to you ‘How is Solar Energy Produced’ and used.

The most important phenomenon for generating solar power is to trap the sunlight that is incident. For this, we use Solar Photovoltaic (PV) modules, which contains cells connected in series and are planted on your rooftops or on ground, depending upon the system configuration. When sunlight falls on these cells, it traps the sunlight and produces a Direct Current (DC). But since our household appliances such as Television, Fan, Bulb and air conditioners etc. work on Alternating Current (AC), it becomes extremely important for us to convert this DC power into AC. For this purpose, we attach an inverter directly with the output of our solar panels which converts DC into AC. Now, the output of the inverter is connected to our main building panel from where electricity is distributed to our household appliances. This is how Solar energy is produced and utilized in our houses.

Going solar has massive advantages for industrial and commercial sector as they have huge energy consumption and thus the savings are even bigger. Also worth pondering is that industries and commercial buildings are provided electricity at higher per unit rate than residential consumers and therefore solar guaranteeing a fixed price for 25 years will result in major savings. However, when it comes to commercial and industrial uses, the process could be different. As in India, the ideal voltage required for running our household and commercial appliances is 240V, single phase or 440V, three phase whereas in big industries some of the equipment may require high voltage between 11kV-33kV range therefore a step-up transformer is included in the setup. This step-up transformer increases the voltage, to the optimum required for the industrial and commercial application. In such cases, the output from the step-up transformer is then connected to the High Tension panel (HT panel), from here electricity is sent across to different machines. It is therefore important to have a solar company evaluate your power requirement and consumption pattern so that you get the most optimum solar solution for your needs.
