Parabolic troughs are used to concentrate sunlight for solar-energy purposes. Some solar cookers have been built that use them in the same way.[citation needed] Generally, the trough is aligned with its focal line horizontal and east-west. The food to be cooked is arranged along this line. The trough is pointed so its axis of symmetry aims at the sun at noon. This requires the trough to be tilted up and down as the seasons progress. At the equinoxes, no movement of the trough is needed during the day to track the sun. At other times of year, there is a period of several hours around noon each day when no tracking is needed. Usually, the cooker is used only during this period, so no automatic sun tracking is incorporated into it. This simplicity makes the design attractive, compared with using a paraboloid. Also, being a single curve, the trough reflector is simpler to construct. However, it suffers from lower efficiency. It is possible to use two parabolic troughs, curved in perpendicular directions, to bring sunlight to a point focus as does a paraboloidal reflector.[citation needed]The incoming light strikes one of the troughs, which sends it toward a line focus. The second trough intercepts the converging light and focuses it to a point. Compared with a single paraboloid, using two partial troughs has important advantages. Each trough is a single curve, which can be made simply by bending a flat sheet of metal. Also, the light that reaches the targeted cooking pot is directed approximately downward, which reduces the danger of damage to the eyes of anyone nearby. On the other hand, there are disadvantages. More mirror material is needed, increasing the cost, and the light is reflected by two surfaces instead of one, which inevitably increases the amount that is lost.

A solar cooker is a device that uses sunlight for energy. They use no fuel and cost nothing to run. They also help slow deforestation and desertification. Solar cookers are also sometimes used for cooking outside, especially when using fire is risky or there is no fuel. Solar box cookers can be made of materials or be manufactured in a factory for sale. There are many kinds of solar box cookers, from small cardboard boxes, that can be used to cook a single meal, to wood and glass boxes built into the sunny side of a house. Although the solar cooker was invented by Horace de Saussure, a Swiss naturalist, as early as 1767, solar box cookers have only become popular since the 1970s. They are found in almost every country of the world.    

Automatic Dusk to Dawn controller(DTDC)/ Timer Extremely Long life LEDs (>50, 000 Hrs) No lamp blackening, No lamp replacement for several years Attractive and weather proof luminaries (IP-65 Rated) UV stabilised acrylic light diffuser   Certified as per MNRE specification Certified for IP65 protection (ERDA) Manufactured at a ISO 90001:2008 certified facility

This is Special type of solar Water Heaters from Steam power, where the capacity matters. They can be expanded or reduced in number as per the requirement. This is a Series of independent water heaters integrated together to cater a bigger size need. This system is very effective as the number of the heaters can be decided as per the requirement. Installation is Possible in series or in parallel. All these factors are decided as per the space available and the application of the system such as Residential complexes, Hotels, Hostels, Townships, Marriage Hall, etc.   Inner Tank – Cooper. Outer Tank – SS – 304. Insulation – Polyurethane 60 mm. Accessories – Cooper & SS 304 High efficiency with maximum absorption. Unlike flat plates solar the tubes can be cleaned easily from inside, scales can be easily removed in case of hard water. Electrical back-up (optional). Specially Designed Structure – SS 304 to Give More Strength & Life. Specially Designed – Heavy Plastic Leg Support. Freedom from Resistant. Very Very Attractive Look. Excellent Service back-up. Range Available – 200 LPD, 300 LPD, 500 LPD. Uses the world’s latest innovative magnetron sputtering technique the special selective black coating where it require that absorbs maximum energy.
