Solar water heating (SWH) systems comprise several innovations and
many mature renewable energy technologies which have been accepted in mostcountries for many years. SWH has been widely used in Israel, Australia, Japan,
Austria, China & India.
In a "close-coupled" SWH system the storage tank is horizontally
mounted immediately above the solar collectors on the roof. No pumping is
required as the hot water naturally rises into the tank through thermosiphon
flow. In a "pump-circulated" system the storage tank is ground or floor mounted
and is below the level of the collectors; a circulating pump moves water or heat
transfer fluid between the tank and the collectors.
SWH systems are designed to deliver the optimum amount of hot water
for most of the year. However, in winter there sometimes may not be sufficient
solar heat gain to deliver sufficient hot water. In this case a gas or electric
They have successful track record of manufacturing Solar Water Heating
Systems, since 1989. Presently they are the top most leader company
manufacturing Sudarshan Saur brand Solar Products.
Manufact uring Setup:
They have well equipped manufacturing setup in which World Class
Solar Product is produced using latest International Technology, under ISO
9001: 2000 Quality Management System, supported by skilled staff. They have
advanced black chrome selective coating plant for coating of solar absorber fins,
which is designed with full technical support from National Aerospace Lab.
(NAL), Bangalore. By using Ultrasonic Bonding Technology They produce
high strength and efficient Solar Absorber Fins.
They are the only company using special Non Stick Lining for Hot Water
Storage Tank. Unique "comparative R & D Test Rig is developed for testing of
system performance & to develop high efficient solar water heating system.They have 100% is-house manufacturing facilities to produce top quality World
Class Solar Products.
Marketing Network & After Sales Supports:
They have widely spread well trained dealers network all over the
country. At the major cities, They have Solar Shopees for customer awareness
towards Solar Energy Products. They have fully fledged team of Solar
Technicians and Supervisors for installation, servicing & training purpose.
Foreign Collaboration:
To manufacture World Class Solar Products, They have adopted latest
called as 'Black body absorption Principle.' Sudarshan Saur Solar Water Heating
System works on this basic principle.
Energy of the SUN rays is absorbed by black coated absorber panel in
solar collector. Due to which absorber panel becomes hot. This heat is
conducted to the water flowing in the tubes of absorber Panel and the water
becomes hot. The water so heated is carried to storage tank. This water
circulation from solar absorber panel to storage tank is achieved by two ways.
A) Thermosyphon circulation:Hot water is lighter than cold water hence it moves upward in the hot
water storage tank. And cold water tries to moves downward. This internal flow
of water particles is called 'Thermosyphon circulation'.
The storage tank is placed
at higher level than collector
box. As the water becomes hot
in the tubes of absorber panel, it
flows upwards in storage tank.The same is replaced by
relatively heavier cold water in
storage tank.
So the flow of water continues till all the water in storage tank attains
highest temperature equal to the temperature in the tubes of absorber panel.
This is a total natural phenomenon, there is no need to start or stop thiscirculation. It will automatically start in the morning hours when sun rays fall on
collector box, and it will automatically stop when sun rays are not there.
Forced Flow Solar Water Heating System :
For Capacities more than 3000 LPDs the pressure produced by the
Thermosyphon circulation is not sufficient to move the water. Hence the
additional pump is required to force the water inside the tubes of absorber panel.
