Jain Sunglow is for pressurized applications & when the water quality is poor.*

* Water testing recommended

Solar Collector

This is heart of the solar system. It consists of copper grid with selectively black chrome coated copper fins ultrasonically welded to the risers. Toughened solar glass, mineral wool insulation, steel sheet for back support & extruded aluminum casing with weather proof joints. These are manufactured with latest BIS standards using state-of-the-art technology to achieve highest efficiency.

Insulated Hot Water Tank

Steel hot water tank with outer cladding of painted & oven baked galvanised sheet, insulated with 40 mm thick PUF insulation. This ensures least overnight temperature drop. Special pressure vessel design for pressurized systems.

Mounting Racks

Generally, mounting racks are designed for flat roofs. Specially designed racks are supplied for sloping roofs or parapet installations. This rack is assembled at site using L-shaped pre-fabricated steel sections, zinc white plated for long life.

Assurance from the Company

Each Jain Solar carries a unique & solid assurance from the Company. It comes from a 3000 crore turnover Company committed to water conservation & environment protection. With over 490 crores of exports in extruded / moulded plastic & micro irrigation systems, galaxy of awards & recognition from TUV NORD for ISO 9001-2000 for all its divisions, the company is poised for a big leap. As a proud owner of Jain Solar Water Heater, welcome to the family of happy and satisfied customers!

Warranty

The Jain Solar Water Heating Systems are backed up by a warranty of 5 years against manufacturing defects subject to the conditions stipulated therein.

Frequently Asked questions (FAQs)

How does the water get heated ?

It is a natural process by which, hot water produced in the collector, moves into the tank and is replaced by cold water from the tank. This cycle repeats till all the water is heated so long as solar radiation is available.

What is the maximum temperature achieved ?

Domestic systems are designed for 60°C, However, in summer or during periods of less use, temperatures up to 85°C are achieved.

What about cloudy/rainy season ?

Jain SWHS will provide hot water for about 300-325 days in a year. For cloudy / rainy days, an optional electric heater can be fitted to boost the water temperature to desired level.

How do we select the capacity ?

For Indian conditions, 25 to 30 liters per person per day is the average hot water use. Accordingly, 125 LPD system is suitable for a family of 4-5 members.

Any maintenance required ?

Use soft water & keep the glass always clean. Check for leakages & valve functioning periodically.

What if the water is hard ?

Select close loop system only. Periodically, clean the tank for any scale buildup.

How about soft loan scheme ?

Soft loan is available for 5 years repayment period upto 80% of project cost. Interest rate is 2% for individuals, 3% for non-profit making & 5% for profit making organizations.

Why Jain Sunlight ?

Benefits : Negligible maintenance, daily water heating expenses almost nil, conserves precious natural resources, exemption from octroi & excise duty, 80% depreciation for commercial use.

Features :Saves energy & environment, easy to install & maintain, no fear of shock/ accidents, long life, huge savings.

Uses :Bungalows, Apartments, Guest Houses, Lodges, Hotels, Hospitals, Heath Clubs, Dairies, and wherever & whenever you need hot water.

Models :Jain Sunlight evacuated tube collector system is for non pressurized application. Available in 100 to 500 LPD. Higher capacity systems are available on request.

Salient Feature Evacuated tube collector

This is heart of the solar system. Evacuated tubes are made up of borosilicate glass coated with AL-N/AL using sputtering technique. This is worlds latest innovative technique of black coating to achieve highest efficiency.

Insulated Hot Water Tank

Stainless Steel hot water tank with outer cladding of G.I. precoated sheet, insulated with 40 mm thick PUF insulation. This ensures least overnight temperature drop.

Mounting Racks

Generally, mounting racks are designed for flat roof. This rack is assembled by SS. Fasteners at site using L-shaped pre-fabricated & powder coated steel sections.

How about rainy season?

Jain Solar is designed for year round performance. It needs about 7 hours of normal solar radiation for desired performance. As an auxiliary support, electric heater is fitted when hot water availability is not as expected.

Frequently Asked questions (FAQs)

How does the water get heated in ETC system?

It is a natural process in which Solar energy is absorbed by the black coating on the outside of the inner tube & the same is transferred to the water inside the tube. Water on the upper side of the vacuum tube becomes hot & lighter in weight & it starts rising up into the tank. At the same time, heavier cold water from the tank comes downward from lower side of the tube. This cycle repeats till all the water is heated so long as solar radiation is available.

What is the maximum temperature achieved ?

Domestic systems are designed for temperature upto 60ºC. However, in summer or during periods of less use, higher temperatures can be achieved.

How do we select the capacity ?

For Indian conditions, 25 to 30 liters per person per day is the average hot water use. Accordingly, 100 LPD system is suitable for a family of 3-4 members.

Any maintenance required ?

Use soft water & keep the glass tubes always clean. Check for leakages & valve functioning periodically. Keep in mind that this system is meant for non-pressurized application only. Air vent to the hot water tank is MUST..

What if the water is hard ?

Select close loop system only. Periodically, clean the tank for any scale buildup.

How about soft loan scheme ?

Soft loan is available for 5 years repayment period upto 80% of project cost. Interest rate is 2% for individuals, 3% for non-profit making & 5% for profit making organizations.
