The summer season in India already has arrived and it is at its peak engulfing almost every part of the Northern region. One cannot imagine living without electricity; people are using air conditioners, desert coolers to combat the intensity of heat. The result is increased consumption of electricity and hence escalated electricity bills.
I think the increased electricity bills during summer seasons are the story of every household not only in India but any part of the world. What are you doing to get out from this situation? Are you making any efforts? First, let us understand the term Energy portfolio.
The Energy portfolio is the basket of external energy resources (like coal, hydro power, petroleum and renewable resources like solar, wind, biomass etc) through which we fulfill our daily energy needs. (1) Understanding the concept
Well, let us take an example and try to find the solution on how to tackle this situation.
Mr. Kumar lives in Delhi with his family in 2 BHK flat. He owns a car which runs on an average 10Kms per day, which consumes petrol of around Rs. 2000 per month. The electricity bill of Mr. Kumar in the month of May last year was Rs. 4,500/-. The details are as follows:
(2) The renewable energy component is absent
His monthly energy consumption portfolio is as follows:
By looking at the above table, we can find out that his portfolio does not have any component of renewable energy resource.
(3) Planning to include renewable energy component in the portfolio
After reviewing his electricity bill, he plans to fulfill his 10% of daily electricity need (10% of 30 units) this summer through solar energy. He plans to install solar PV at his home which is able to save 3 units per day. He already has Microtek sine wave inverter which is compatible with the solar system. His only needs are solar panels, charge controller, iron frames to support the system and the wires to connect the components. He met a solar installer and after analysing the situation, a 900 watt solar system (panels with 25 years performance warranty and 5 years mechanical warranty) is recommended to him which will save 3 units per day. The whole system will cost him around Rs. 50,000/- all inclusive (Please read "What is the average cost of solar roof in India ?" for better understanding).
By doing some calculations, he finds out that the payback period of his system will be in between 5 – 6 years (I am excluding the cost of the inverter as Mr. Kumar already has one at his home). Now, Mr. Kumar will enjoy free electricity till the life of the solar system, which is 25 years. After proper installation, the system starts working and generating electricity from day one. Now his new monthly energy portfolio looks something like this:
(4) Mr. Kumar has become electricity generator
Here the important thing is that now Mr. Kumar is generating electricity by using the power of sun and consuming it. The 7% energy is generated at his own home which is providing him 3 units on daily basis. This is something very interesting and fascinating.
He has diversified his energy consumption portfolio by adding one component in his portfolio, which is solar energy resource that is helping him in fulfilling 7% of his energy needs. Moreover, after payback the energy produced is almost free to him till the life of the system. Conclusion
Here in this article Mr. Kumar has taken the right step and reduced his monthly electricity bill from Rs. 4500 to Rs. 4050 (10% saving) and he has become the energy generator by installing solar system at his home. So, what is your energy portfolio this summer?
A gradual, small but continuous shift in this direction will make you self reliant which will build strong foundation of pollution free environment. Related Articles:
