Over the years, scientists and environmentalists have been looking for an alternative source of electricity or power supply that is cheaper as well as abundant than the traditional electrical energy. The electromagnetically generated electricity is turning costlier with every passing year. Even the resources required to create the necessary power is depleting with time. The inevitable increase in demand for electricity had left every organization into a deep well of thoughts.
Thus came into existence an independent source of energy that is surplus in nature and unlimited. The energy obtained from Sun; solar energy.
The technology behind solar energy
The easy-to-go steps:
- The radiant rays hit the open surface of the panels that generate an electric field.
- A wiring system provides passage for the generated electricity to travel.
- Traveling electricity make its way into an inverter where it undergoes conversion from DC to AC.
- The inverter is attached to another wiring connection that supplies the converted electricity to the primary house circuit.
- Now after the electricity is consumed, the remaining electricity is flown back grid. This process stores as well provides credit for the generation of excess electricity.
The transmission of solar energy can be distributive or centralized. However, both of the systems can reserve energy even after the Sun has set down. The widespread adoption of this energy also requires large-scale storage of it.
Every coin has two phases; similarly, there are certain advantages of solar energy against the disadvantages.
Pros and Cons of solar energy
|Cost effective when it comes to bill payment.||Earnest money, the inspection fee, and the appraisal fee are high.|
|You can pay even in installments for the total price.||Solar energy is sporadic in nature.|
|Environmental friendly.||The large-size panels affect the environment around them.|
|After a certain time interval you will get back the investment price in terms of savings.||The installations of panels require a lot of space.|
|Constant supply of radiant sun rays is very important in order to storage energy for later use.|
Advantages of solar energy
- Boon to your pocket
The source of ample energy is Sun; the generated electricity is cost-effective and can even turn free. There will be an initial investment, but after that, you will witness a massive downfall in your electric bill, and even it might become negligible. A solar panel can deliver services for 15-20 years. So you can now plan your estimates zero bill saving.
- Enhances the value of your home
If you have a transferable job or plan to shift to a new destination, you might be willing to sell your house. One of the cons concerning solar panels is that they are not portable. But there is another angle to look into the fact that your humble shelter’s value increases when it possesses a system like this.
Disadvantages of solar energy
- Incompatibility of installation area
The installation area of these panels must be spacious. The direct rays of the Sun must be directed on these panels to letting maximum storage of energy. However, the vintage and slanting roofs are not safe enough to pressure these bulky devices.
Residential solar energy
When solar energy is used for household purposes and to supply electricity, it is known as resident solar energy. The effect responsible for it is the photovoltaic effect.
The notable features of residential solar energy:
They must be capable of fulfilling the power requirement of the home.
The power must be supplied as AC, and then only the different electrical appliances can be used.
More than one solar panel is required to absorb energy for supporting a house. On average, 30 watts of solar power are interested in 1 hour when exposed to Sun. For using solar energy at night, a chargeable battery is a must. The battery gets charged all day by the sunshine.
An inverter is a device that transforms DC to AC.
The power stored by the batteries or cells must be well connected using cables and wires to develop a channel for the adequate usage of solar energy worldwide.
The cost incurred for residential solar system.
How long does a solar panel last?
The manufacturing company plays a significant role in terms of the shelf life of a solar panel. Naturally, they degrade in service and quality over time. Typically, they might be useful for 15-20 years, but they might even perform correctly even after that. Many panels expire after 50 years.
Typically, rich branded panels provide 90% efficiency for the first ten years, and gradually, with further aging, the efficiency decreases. However, the panels continue to generate electricity at a pretty nominal rate.
One of the primary reasons that lead to the deficiency of these panels is micro cracks. The micro-cracks act as hurdles in the electrons’ pathway, which leads to a considerable decrement in electricity generation.
Hope you have now realized the boon and bane of solar energy. Nonetheless, solar energy is the future of energy production in this world. The world requires a quick alternative to electromagnetic electricity.
