A solar water heater is a product that uses solar energy to heat-up water. Hot water is required especially in colder parts of India and other areas that become cold in winter. In addition, hot water is required in daily life, for example for more effectively washing clothes. In all these cases, solar water heaters can be a cost-effective option. To accommodate these requirements, solar water heater in Delhi NCR and in other parts of India are available more easily. To give a better idea of the benefits they can provide, the six main benefits are highlighted below.
Solar Water Heaters Use Solar Energy which is Renewable and Environmentally Friendly
India has an abundance of sunshine that is available practically throughout the year in most places. This can be made use of through different solar panel materials. The monocrystalline solar panels are installed in areas receiving strong uninterrupted sunlight throughout the year. However, the polycrystalline solar panels are installed in areas where this does not hold true.
As a renewable source of energy, solar energy is not finite like fossil fuels that are non-renewable. For this reason, it can be made available in a sustainable manner for a larger number of people. Additionally, as it leads to comparatively lower levels of pollution, it is environmentally friendly.
There are Different Types of Systems Available to accommodate different Requirements
The types of systems include the Evacuated Tube Collectors/ETC Systems and the Flat Plate Collectors/FPC Systems. Both Systems are available with the option of a pump, which transfers water to the storage tank. The pump is an optional choice, recommended more for industrial rather than domestic usage.
Though the Evacuated Tube Collectors/ETC Systems are less expensive, they are made of glass and more prone to breakage. The Flat Plate Collectors/FPC Systems, on the other hand, are made of metal, last longer but are more expensive. For cold areas, however, where temperatures reach below zero, the former is a better choice.The reason being, that the latter in these areas require anti-freeze-solution that increases costs.
Various Sizes of Solar Water Heaters Conveniently Accommodate Different Needs
The size of a solar water heater is measured in terms of liters of hot water per day. It signifies the capacity, which begins at one hundred liters of hot water per day. Other sizes include two hundred, two-hundred-and-fifty, three hundred, and three-hundred-and-fifty liters of hot water per day respectively.
The capacity, in turn, determines the number of people it can serve. For example, one hundred liters of hot water per day is recommended for four people. The size also determines the amount of space required by a solar water heater. This space additionally varies according to the type of System used. The Evacuated Tube Collectors/ETC Systems tend to take up less space than the Flat Plate Collectors/FPC Systems. For example, one
A hundred liters solar water heater requires 1.52metres for the former and 22metres for the latter System respectively.
It is Possible to Make Savings through Solar Water Heaters
The total amount of approximate attainable savings is measured on the basis of two criteria. The first criterion describes the approximate number of days hot water can be used in a year. The second criterion describes the approximate savings in electricity on a yearly-basis and full heater usage. This is illustrated through the example of one hundred liters of hot water per day capacity solar water heater.
The first criterion varies according to the region, i.e. northern, eastern, southern and western India. Accordingly, the approximate number of days hot water can be used in a year varies from two hundred-three hundred days. The second criterion is calculated on the basis of the first criterion in terms of approximate electricity units. Accordingly, savings on electricity varies in a year from approximately one thousand to one-thousand-and-five-hundred.
5.Government-prescribed Subsidies are Also Available
Customers who buy solar water heaters can avail of certain Government-prescribed subsidies. But, as they do vary region-wise and details and amounts can change from time to time, current/latest updates are important.Along with this, the latest news and an online search can give a more comprehensive idea of the Government-prescribed subsidies.
It is Also Possible to Conserve Non-Renewable Electricity By Using it Only as a Backup
Electricity produced through non-renewable resources is finite. Meaning that once it is used up, it will no longer be available for future generations. For this reason, electricity produced through renewable resources like solar energy is gaining focus and being emphasized. In this way, non-renewable resources can be used sparingly and conserved properly.
Thus, solar water heater in Delhi NCR and other areas, provide many benefits including daily requirements and combating cold. Many regions of India require hot water practically throughout the year, and especially in winter. In all these cases, solar water heaters steadily and significantly lessen household electricity bills. In addition and very importantly, they protect the environment and conserve precious non-renewable resources.
