At initial stages when we studied the potential for application of Solar
water Heaters in day-to-day requirements, we found it to be a promising
application. Consider any place like House, Hotels, Lodges, Hostels, Industries,
and Colleges etc., most (80%) of the energy consumed by these organizations is
used for heating water whether they are in the form of Electricity, Gas or Oil.
Since major part of the energy consumed was for heating water, the need
was to find out an alternative way in which water could be heated by using the
free and naturally available energy from the Sun. This led to the introduction
of Solar Water Heaters.
Since the Solar Energy is inexhaustible and is continuously available, we
not only gave importance in designing & manufacturing efficient and
effective systems but also made sure that the systems once installed should
provide years of dependable service. We worked on the principle that “ Solar
Energy is an inexhaustible source of energy and hence increase in the life of
the system meant increase in energy saving”. Thus we decided to provide our
customers a quality product at a competitive price. Back to Top

What is a “Solar Energy Device”? A device that is designed to
perform certain function by using the free and natural
Light energy from the Sun is called a “Solar Energy Device”. The function
could be Heating water from the sunlight, Heating Air from
the Sunlight, producing Electricity
from sunlight and also cooking food using the Sunlight. Back to Top
What is a solar water Heater (SWH)?A Solar Water Heater is a device that helps us in heating the water by using the free and Natural Light energy from the Sun. The water can be heated to any desired temperature above normal Temperature but cannot exceed the boiling point temperature (100°C). Back to Top
Why Use Solar Heating Systems?Today, solar heating is becoming more important than ever before. Natural gas and oil, which is burned to heat our homes and water is limited. As reserves of gas and oil shrink, these fuels become more expensive. If more people began using solar heating systems, fossil fuels such as oils and gas would become less expensive and last longer.
Burning natural gas and oil in our heating systems also causes air
pollution. Even
electric water and space heaters cause air pollution indirectly, because coal
and natural gas is burned to
produce Electricity in large power plants. So if more people
used solar energy to heat the air and water in their homes, our
environment would be
cleaner. Back to Top
What are the basic components of a Solar Water Heater?The basic components that is required for the effective working of a Solar Water Heater are 1) Collectors, 2) Insulated Storage tanks, 3) Cold water supply tank, and 4) Pipeline interconnecting them. Depending on the system, size pumps may also be included in the system components. Back to Top
What are solar collectors, and how do they work?Collectors form the most important part of the SWH system because they serve the basic purpose of heating water. Solar collectors trap the sun's rays to produce heat. Most solar collectors are boxes, frames, or Rooms that contain these parts: (1) clear covers that let in solar energy (2) dark surfaces inside, called absorber plates, that soak up heat; (3) insulation materials to prevent heat from escaping; and (4) vents Or pipes that carry the heated air or liquid from inside the collector to where it can be used. Cover
: Many
clear materials can be used as covers for solar collectors, but glass is the most common
material. Glass can be made quickly and easily. The special glass used
in solar collector’s resists breaking and scratching. When sunlight
passes through glass and hits a
surface inside a solar collector, it changes into heat. Although glass
allows sunlight to pass through, it also traps the heat produced inside
the collector. Absorbers:
The heat produced inside a solar collector is soaked up by metal sheets
or containers filled
with water. These dark-colored objects that soak up heat are called absorbers.
Without absorbers, solar heating systems would not produce enough heat to
warm rooms inside your house or Water. Insulation
:
Heat always tries to move from a hotter object to a colder one. Insulation
is what prevents or slows down the
movement of heat. Because insulation prevents the heat
inside a solar collector from moving to the outside where the temperature
is lower, it is an important part of any
solar collector. Vents
and Pipes :
When a solar collector is working properly, the heat that it produces
moves from the collector to an
area where that heat can be used. If the collector's job is to heat
water, then pipes, tubes, and pumps move
water from the collector to water utility equipment
or point. Collectors are basically of 3 types namely Flat Plate Collectors, Vacuum Tube Collectors & Parabolic concentrating collectors. Solar Flat Plate collectors are the most widely used collectors for Water Heating systems because of there simplicity in design, easy operation and Installation & they form a very good cost effective solution for hot water needs. Back to Top
What is Insulated Storage tank and why they need to be insulated?All Solar water-heating systems need a storage tank to store the cold water that is to be supplied to the collector and to store the hot water that comes from the collector. Since the natural law says that any hot substance tends to radiate heat to its surroundings to get back to its lowest energy state, it is obvious that the hot water in the storage tank also radiates heat, thus to prevent this radiation and cooling of water the storage tank is Insulated with Rockwool and Aluminium cladding.

What are the requirements for installing a Solar Water Heater?A shadow free area on the rooftop with enough of Sunlight. A cold-water tank at a height of 7-8ft from the terrace level. Back to Top
Is solar water heater a good investment?Solar water heaters, both solar domestic hot water systems & Solar Commercial hot water systems may be a good investment for you and your family. Solar water heaters are cost competitive in many applications when you account for the total energy costs over the life of the system. Although the initial cost of solar water heaters are higher than that of conventional water heaters, the fuel (sunshine) is free. plus, they are environmentally friendly. To take advantage of these heaters, you must have an unshaded, south-facing location (a roof, for example) on your property. However of all the Solar energy devices in the market, Solar water heating systems are found to be the most reliable, durable and are backed up by longest warranty period of all other solar energy devices. Solar water Heaters are known to have the fastest repayment of investment. The larger the capacity of the system the more fast is the repayment period. Back to Top
Does this Solar Water Heater work in any climates?Solar Water Heaters can operate in any climate. Performance varies depending, in part, on how much solar energy is available at the site, but also on how cold the water coming into the system is. The Colder the water, the more efficiently the system operates. Only during rainy season you will need a Conventional backup system (Electric). Back to Top
How does solar water heating systems work?Thermo
siphon Systems
A thermo siphon system relies on warm water rising, a phenomenon known as
natural convection, to circulate water through the collectors and to the tank.
In this type of installation, the tank must be above the collector. As water in
the collector heats, it becomes lighter and rises naturally into the tank above.
Meanwhile, cooler water in the tank flows down pipes to the bottom of the
collector, causing circulation throughout the system. The storage tank is
attached to the top of the collector so that thermo siphoning can occur. These
systems are reliable and relatively inexpensive but require careful planning in
new construction because the water tanks are heavy. Forced

What are the benefits of installing Solar Water Heating Systems ?There
are many benefits to owning a solar water heater, and number one is
economics. Solar water heater economics compare quite favorably with
those of electric water heaters, while the economics aren’t quite
attractive when compared with those of gas water heaters. Heating water
with the sun also means long-term benefits, such as being cushioned from future
fuel shortages and price increases, and environmental benefits. Economic
Benefits
Many homebuilders choose electric water heaters because they are easy to install
and relatively inexpensive to purchase. However, research shows that an average
household with an electric water heater spends about 75% of its home energy
costs on heating water.
It makes economic sense to think beyond the initial purchase price and consider
lifetime energy costs, or how much you will spend on energy to use the appliance
over its lifetime. It is found that solar water heaters offered the largest
potential savings, with solar water-heater owners saving as much as 50% to 85%
annually on their utility bills over the cost of electric water heating.
Depending on the price of fuel sources, the solar water heater can be more
economical over the lifetime of the system than heating water with electricity,
fuel oil, propane, or even natural gas because the fuel (sunshine) is free.
Paybacks vary widely, but you can expect a fast payback on a well-designed and
properly installed solar water heater. (Simple payback is the length of time
required to recover your investment through reduced or avoided energy costs.)
You can expect shorter paybacks in areas with higher energy costs. After the
payback period, you accrue the savings over the life of the system, which ranges
from 15 to 25 years, depending on the system and how well it is maintained.
You can determine the simple payback of a solar water heater by first
determining the net cost of the system. Net costs include the total installed
cost less any tax incentives or utility rebates. (See the box for more
information.) After you calculate the net cost of the system, calculate the
annual fuel savings and divide the net investment by this number to determine
the simple payback.
If you are building a new home or refinancing your present home to do a major
renovation, the economics are even more attractive. Long-Term
Benefits
Solar water heaters offer long-term benefits that go beyond simple economics. In
addition to having free hot water after the system has paid for itself in
reduced utility bills, you and your family will be cushioned from future fuel
shortages and price increases. You will also be doing your part to reduce this
country's dependence on foreign oil. Environmental
Benefits
Solar water heaters do not pollute. By investing in one, you will be avoiding
carbon dioxide, nitrogen oxides, sulfur dioxide, and the other air pollution and
wastes created when your utility generates power or you burn fuel to heat your
household water. When a solar water heater replaces an electric water heater,
the electricity displaced over 20 years represents more than 50 tons of avoided
carbon dioxide emissions alone. Carbon dioxide traps heat in the upper
atmosphere, thus contributing to the greenhouse effect. Be
a Smart Consumer Take the same
care in choosing a solar water heater that you would in the purchase of any
major appliance. Your best protection is to consider only certified and labeled
systems. A
