To obtain distilled water using only solar energy, this solar still is ideal. It is small and portable and delivers from 2.5 to 3 litres of pure distilled water per day when full sunshine is available. Ideal for use where highly saline, brackish or dirty water is available. Fibreglass body, toughened glass cover, high efficiency designGives about 2.5 to 3 litres of distilled water per day and saves 3 KWH/day: payback in about 2 years' timeRaw water holding capacity: 20 litres, area required 1.25 M2 Life span 10 years, negligible maintenance, nil energy consumptionPayback period 2 years max.

At the heart of any solar photovoltaic system is the solar photovoltaic module which transforms light energy to electricity. A standard module has a number of silicon crystalline or amorphous cells connected in series/parallel configuration to get the required voltage/current. A number of such modules are connected in series/parallel combination to get the required power output. "AVIN"®photovoltaic systems use high efficiency modules for the best performance and value for money. Solar Power :- Solar Power Generating Units utilise an array of spv modules which are used to charge a battery through a charge control unit and the batteries drive an inverter which acts as a centralized power generating unit. Capacities range from 0.5 KVA to 5KVA and in MW.

Solar Passive Architecture involves blending architectural principles and solar energy to fashion interiors which remain warm in winter and cool in summer - year-round comfortable environment. Best Implementation of solar passive architecture takes place at the design stage. Retroactive designing is possible but involves more expense and labour whereas designing a building with solar passive architecture as the basis makes for a better created environmentally and aesthetically pleasing workspace. A house cooled/heated with solar passive architecture not only provides a comfortable environment the year round but also saves a lot in energy bills. "AVIN"® assists architects and prospective homeowners in designing and implementing passive solar architecture to build a structure that will be pleasant to live in irrespective of seasons.

Solar Lanterns are a boon to rural households where, after dark, carrying on any sort of work is practically impossible. Especially affected are women and students who find it difficult to work and study "AVIN"® Solar Lanterns are the result of extensive study of the markets and requirements of actual users. Main features are : A high quality photovoltaic panel of 10/12Wp capacity A tough moulded plastic body for the electronics and battery and a clear acrylic moulded shell for the lighting. Integrated charge controller and low voltage switch off in the electronics and indicators for charging and low voltage. High quality long life CFL lamp of 7, 9 or 11 watts capacity (7W standard, 9 and 11W optional). A sealed maintenance free battery of 12V, 7/10 Ah capacity. 3 Hour operation with 7 Watt CFL, slightly less with 9 and 11W Introduction of solar lanterns has changed life dramatically in such areas Women can now work 3 hours after finishing their household chores and supplement income of the household. Students can study for 3 hours Solar Lanterns are revolutionising life in such rural areas. Solar lanterns can also be used as camping light, portable inspection light, in hospitals, check posts...uses are myriad.      

"AVIN"® has designed and developed a solar dryer. The dryer has no moving parts and work on passive convection and heating principle. Toughened glass glazing aperture is 1 mtr x 2 mtrs. Holding capacity is 0.75 cu. mtrs. Various types of materials can be dried. Material to be dried is fed into a chamber from doors provided at the rear of the dryer. Dryer is mounted on castors for easy movement and transportation In addition to such portable dryers "AVIN"® also designs custom dryers and drying systems to suit individual requirements.

Solar cooker shown alongside is developed for a normal family size of 6 to 8 members. Cooker body is twin wall aluminum sheet fabricated. Twin glass sheets with air insulation allow for maximum solar heat entrapment. Four containers are provided to cook food. These containers are of aluminum and are blackodized. The hinged cover to the cooker has a reflecting mirror and the angle of the mirror can be varied . This type of cooker is ideal for rural and semi-urban settings and will also work fine in urban centres, saving housewives an enormous amount of fuel every year. In addition to personal cookers described above cookers can be designed and commissioned for community cooking using various design aspects of solar energy utilization.

Domestic systems can be mounted on individual homes as well as apartments. Shown above are 3 systems mounted on an apartment block, supplying hot water individually to 3 different households. We offer systems for individual house owners as well as systems for community housing projects. Only one in the whole world! Auto Descale system collectors are optionally provided to our clients. Hard water fed to solar heating system tends to form scales which choke the tubes of solar collectors. It is desirable to de-scale the system at least once in two years in summer to maintain its performance. Depending on hardness of water more frequent de-scaling may be necessary. Even de-mineralized water can affect the system performance. International Engg & Trading Co. optionally provides "AVIN"® AUTO DE-SCALING SYSTEM which prevents and/or delays the formation of scales inside the collector tubes. This preventive "AVIN"® AUTO DE-SCALING METHOD prevents and/or delays the scale formation. Scale formation is directly related to PPM and/or chemistry of water. In the process of auto de-scaling some external MS nipples, couplings, etc. Decay and erode and are required to be replaced periodically which ultimately saves the costly collector. This further improves efficiency and durability. Consider all parameters carefully before selecting a plastic collector based SWH: price is not the main and only consideration!
