Solar Water Heaters are the one of the solar products which has managed to cut off the government subsidy. Solar power in India has the advantage with the JNNSM subsidy policy promoting by government. The paying back period is too short, and it also replaces the need of electric water heaters used in houses and commercial environments where sometimes they may face a scarcity of electricity supply to their places. The other various reasons for the popularity of solar water heaters are that it can be built easily and can be installed with ease. Here, China has moved a bit towards success in making most installed solar water heater in the world than any other country. India is also not lagging behind and showing its growth towards installing the solar water heaters on the roofs of the households in India. It is gaining popularity in India because of the subsidy available through MNRE for buying solar water heaters. Water heaters are available in the market with various capacities, qualities and at the best prices so that it is affordable for people in India. The installing of whole turnkey consists of solar water heaters; piping systems and maintenance is done by our solar installer. Solar Water Market in India: We have witnessed in the last 4-5 years that growth in the market has been increased from the past 15 years to 20% CAGR due to certain reasons as specified here. Not only there is an increase in growth but also it has acquired a speed in India’s solar water heater market that is around 2.5 million square meters. The 50 percent of the solar water heater that have been installed is found to be in Karnataka and Maharashtra. India has the potential for receiving very high solar radiations which makes it useful for solar water heater. The solar water heaters are mostly installed by the households, which makes the decline in installations for commercial establishments more than 80%. Commercial establishments are still lagging behind in installing solar water heaters. It is seen that, in India, the growth has reached up to 20%, and around 1 million households have installed solar water heater, which might have cost them at Rs 30000 ($650). You can also be benefited by SWH as it saves fuel and pollution...

The change of environment and the energy deficiency encourages the harnessing of solar energy. Due to the daily rising cost of fossil fuels, the government feels need to reduce the cost of solar water heater. With the use of solar thermal collectors, they convert natural sunlight into heat to heat up the water. For example, China is a country where 27 million roofs have rooftop solar water heaters. The 4000 companies in China are manufacturing these devices at an affordable rate and with a great technology which has approached villages who have scarcity of electricity yet. For villagers, they provide it at an affordable rate, about $200 so that they get a solar water heater installed on their roof and enjoy hot showers. China has boasted to applying this technology, and they are achieving a great success in their business. By 2020, Beijing has planned to make the present 114 million square meters of rooftop solar collectors to heat water up to 300 million square meters. The energy required for these installation facilities in China is same as the generation of electricity by 49 coal-fired power plants. Not so far where even in developing countries India and Brazil may also see that millions of households will be using this inexpensive water heating technology. This just would appear in villages just as it appeared when cell phones replaced the use of traditional telephone lines. The initial cost seems may be quite high, but after the installation you will enjoy free life long hot water whenever necessary. Since the energy costs are costly in Europe, this rooftop technology is spreading wide in that country. Even in Austria about 15 percent households have installed rooftop solar water heater to get hot water. As in China, almost all the villages of Austria have installed this rooftop collector. Germany is also not lagging behind. As China and European Union have achieved their goals, Japan and United States are also finding new technologies with their recent projects which may heat up a total of 1,180 million square meters of space and water heating capacity by...

How interest rate subsidies are beneficial than capital subsidies The cost of electricity and fuels are increasing day by day as they are non-renewable sources of energy, and it is not prudent to use this energy to heat water for our use. There is an alternate way by which we can get hot water without incurring any cost. By installing solar water heaters at home, a person can save his money, which was going to be spent on other expensive energy resources. Solar water heaters utilize solar energy to heat water presented in the tank and hence; it is free of cost. In most of the homes located in cities, solar water heaters are installed. It is made possible due to low cost financing which is given by the commercial banks. Ministry of Non-Conventional Energy Sources (MNES) provides regular interest rates. If we take an example of Canara bank, which is headquartered in Bangalore, it provides loans up to two percent for a person whereas, it increases up to three and five percent for institutions and commercial entities respectively. On a whole, a commercial bank can finance up to 85 percent of the project cost. During earlier days of 1990s, there were very few numbers of solar water system manufacturers. The subsidies were guided and kept under MNES supervision all over the country. For example, there were less than six manufacturers of solar water system. To increase the production, the interest subsidy enticed many commercial banks to pass loans and finance for a solar water heating system, which lead to the increment and development of many other solar water heater manufacturers. Due to this there were more than sixty manufacturers of solar water systems in Karnataka alone. The solar water systems which are manufactured should be collaborating with the financial institutions so that the systems get qualified for general purposes. If the system is not performing as well, there can be non payment of the loan which leads to the rejection of the supplier. Due to the availability of the financial programs solar water heaters are installed in various places where there is a need of hot water like a house, hospitals, sugar mills, food processing units, milk processing plants etc. Such changes should be done in the society and utilization of renewable sources of energy must be increased. We can use other technologies as well to conserve energy like solar photovoltaic, biogas, wind and tidal...

In order to heat water, there is a requirement of loads of energy. A solar water heating system utilizes solar energy to heat the water, and hence, is economical than another source of energy. Many plans and guidelines are made by India’s Ministry of New and Renewable Energy (MNRE to install solar water heating systems in houses as well as at buildings. There are certain calculations included in the guidelines like for bathing purpose a person will require 20 liters of hot water and for other common usage water will require around 30 liters per person. These stats can increase up to 25% if they are done for a community where there are a number of houses and flats. Ministry of new and renewable energy (MNRE) also suggests a shade free installation area after every three or four meters. Anyway, there are many more factors which may affect this like usages of long piping for the transfer of hot water and consumption of more amount of hot...

Surat was the first city in India where it was made compulsory to use solar water heating system for hot water in all residential apartments and houses. In the starting of this year, our Union urban development ministry has taken adequate and necessary actions to modify and change the houses so that it becomes fit for solar water systems in all 58 cities to make it a solar city. The Surat municipal corporation (SMC) is going to take necessary actions to modify the houses and construct it in such a way that solar water systems can be installed in each and every 10.2 lakh houses and 65,000 buildings present out there. Anyway, solar water heating in only a small step made in Surat, to make it a solar city. There are many more activities going on like installing solar panels in producing electricity and replacing all normal street lights to CFLs and tube lights. The aim is to use all sorts of renewable sources of energy so that the use of a conventional source gets reduced by 10 to 15 percent in the next five years. Even SMC has appointed a meeting with WISE (World Institute of sustainable energy) to point out the proper plans to install solar water heating...

Solar water heater converts solar energy into heat energy for making water warm. This can be achieved by using solar water heating panels instead of photovoltaic panels that convert heat energy into electrical energy. Use of Solar Energy for water heating is quite efficient, economical & pollution free method. A typical solar water heater consists of solar collector panels containing tubes or coils with water. They are placed in an area of abundant sunlight where it collects the Sun’s energy and transfers it to water for making it warm. For effective absorption of solar energy, the collector is made with black color & is properly insulated. There are two types of System. One is called Passive and another is Active. In a passive system, natural circulation is used for flow of water where water when gets hot, has a tendency to rise upwards and gets collected in a storage tank. While in Active system, forced circulation is used through an external pump, for hot water circulation. The solar water heater system works best in the sunny climate, but it doesn’t mean that it will not work in other climates. However efficiency may change accordingly. In cold climates, tubes are filled with non toxic antifreeze, to improve efficiency of the solar water heating system. Solar water Heaters can also be used as pre-heaters, and additional temperature can be achieved by using electric or gas water heater. This process saves a lot of money as the hot water heater does not have to increase as much temperature of the...
