At present, the entire world is facing global warming. The temperature of the earth is growing at a rapid rate. Every year the earth’s temperature rises by 1 degree.
In many parts of India like Delhi, Rajasthan, Gujarat, etc., the temperature during the daytime reaches up to 45 – 47 degrees. And because of it more & more people are using air-conditioner which is further increasing the electricity consumption and increases the outside temperature. The rising electricity consumption is reflecting in the monthly electricity bill.
So now the question is, how to reduce this rapidly growing temperature and the electricity consumption, at the same time?
In this blog, we will understand how we can reduce the temperature along with reducing our electricity bills.
- What is rooftop solar & how can it help to reduce electricity bills?
- What is Terrace Gardening & how does it reduce your home temperature?
- Why is terrace gardening important for urban areas?
- How does terrace gardening be beneficial to rooftop solar?
Rooftop Solar:
Rooftop solar is the photovoltaic system that is mounted on the rooftop of residential and commercial buildings & generates electricity from solar energy.
There are two types of rooftop solar solutions available in the market: On-Grid & Off-Grid rooftop solar solutions.
In an on-grid solar solution, the consumer has connectivity to the utility grid. The consumer uses solar-generated electricity in the daytime, and the night time consumes the electricity from the grid. Since the consumer has grid connectivity, surplus power is transferred to the grid.
Furthermore, in the on-grid solar system, there are 2 types of grid connectivity. First is Net Metering in which a single bidirectional electric meter is used to calculate the total power imported and exported.
The other is Gross Metering, in which there are 2 separate electric meters are used to calculate the total power exported and imported separately. In the case of gross metering, the consumer does not consume solar power directly. All of the power generated is exported to the grid and from the grid, consumer import all of the required power.
In an off-grid solar solution, the consumer stores the generated electricity in the solar batteries & consumes it as per their requirement.
If we compare both the solar solutions, on-grid solar solutions are much cheaper in comparison to off-grid solar solutions as it doesn’t require batteries for power storage.
To choose the perfect rooftop solar solution for your home, you must be aware of the total power consumption. For that, you can do the load calculation of that place with the help of solar experts.
If we talk about the average power consumption, which includes fans, lights, laptops, TVs, fridges, etc., then a 2 KW of the solar solution is enough for this. But to run large appliances like AC, submersible, and geyser, etc. you need a more powerful solar solution will be required.
The top five rooftop solar installation states in India are:
- Gujarat
- Karnataka
- Rajasthan
- Maharashtra
- Delhi
Gujarat is at the number one position in this list, and also due to good grid connectivity and solar tariff, people are adopting on-grid solar solutions more and more here.
Terrace Gardening:
The terrace garden is also known as a rooftop garden. In this process, the house-owner grows fruits, vegetables & flowers on the terrace or balconies of the building. If seen, this method was used as kitchen garden in maximum homes long ago, which has shifted to the roof of the houses due to lack of space. This scenario is very popular in urban areas because of the perfect uses of the rooftop along with the greener. This is the only way to utilize every kind of land and place.
Why it is significant to the urban areas:
- Fresh & Organic Products: If you have a terrace garden, you will get fresh and pesticide-free products along with the fresh air to breathe.
- Reducing pollution along with the temperature: Plants help to increase the flow of oxygen and decrease the rate of pollution. Plants control the quantity of carbon-di-oxide also. Apart from this, if some building has a terrace garden, the indoor temperature of the building will be 6 to 8 degrees less in comparison to another one. Because of this, the consumption of electricity will also be decreased since the use of air conditioners and other appliances would be less.
