SYSTEM OPERATION SOLAR THERMAL: There are two types of solar water heating systems, based on type of circulation; 1. Thermosyphon 2. Forced circulation All domestic and industrial systems upto 4000 LPD (liters per day) @ 60 deg.C,; works on the principle of thermosyphon. Industrial systems beyond 4000 LPD to any capacity will work on forced circulation principle.   Thermosyphon system:: The system works on a principle called "THERMOSYPHON" (Natural circulation).Due to density difference between the cold & hot Water, the lighter hot water flows up into the tank and the heavier cold water enters the collector. Solar radiation incident on the collector panels heats the absorber. This heat is transferred to the water contained in the absorber & becomes less dense than the water in the storage tank. Hot water starts rising and settles at the top of the storage tank. Simultaneously cold water descends to the collector absorber tubes, gets heated up and the cycle repeats. The circulation in the system during the heating process is purely due to the difference of density only. There is no other mechanical moving part, hence the system reliability is very high. At the end of the day when radiation is zero (after dark / sun set) the collector will contain heavier cold water and the tank will have lighter hot water. This will ensure that there will be no circulation during night & hence no conduction losses on account of this. The hot water storage tank is well insulated to retain the hot water temperature and to minimize the overnight temperature drop / heat losses. The Sacrificial Anode (Only for SS tank) prevents the tank from galvanic corrosion. For the monsoon / cloudy days the system is-fitted with Electrical back up heater with thermostat. Forced circulation system: In forced circulation systems, two pumps in tandem are used for circulation of water between collector bank & system insulated tank. The pump operation is controlled by OTC (Differential Temperature Controller), which is fitted Inside the Control panel. OTC senses the cold & hot water temperature through two sensors, one fitted at the bottom of the tank to sense cold water temperature & the other fitted at the top of the last collector of the row in the collector bank, to sense the hot water temperature inside the collector The difference in temperature between the two sensor points is the criteria for the operation of the pump that is controlled through DTC. This temperature difference can be set between 0 to 10 deg, C. Solar radiation falling on the collector heats up the water inside the absorber. The temperature of water starts gradually increasing compared to the water temperature inside the tank. When this temperature difference between the sensor points reaches the preset temperature difference in DTC, the pump is switched "ON". This will result in entry of cold-water form the system-insulated tank into the collector bank & discharge of hot water from the collector bank to the system insulated tank. The process of switching ON & QFF of the pump & circulation of water continues till the end of the day. By the end of the day, the entire quantity of water in the tank reaches the system-designed temperature, provided the radiation level is at minimum of 800 watts per sq.mtr. The process of switching ON & QFF of the pump & circulation of water continues till the end of the day. By the end of the day, the entire quantity of water in the tank reaches the system-designed temperature, provided the radiation level is at minimum of 800 watts per sq.mtr.

SPECIAL FEATURES PROVIDED IN THE SYSTEM Provided in the System   System Dry Run Protection, System High Pressure Protection, System Extreme High Temperature Protection, System Evacuation Protection, Sacrificial Anode-of-Magnesium, Electrical Backup, Pressure Reducing Value, Air Relief Valve / Vent. What’s…Vacuum Tube Collector type Solar Water Heaters works efficiently in cold climates or in 70 Deg. Hot water outlet applications? The construction of the collector tube is similar to a thermos flask, piece in that it comprises of two borosilicate glass tubes, one sealed inside the other. The outside of the inner glass tube is coated with a solar selector surface (Al-N/Al) & the space between the two tubes is evacuated & maintained at a high vacuum. This Vacuum created inside the high strength borosilicate glass tube act as an insulator supporting heat loss & enhanced performance. The use of 3.3 borosilicate glass makes this vacuum tube highly resistant to chemical & thermal shock They are designed to suit hard water heating. There is no bonding of scales on smooth surface of glass tube. Cleaning of collector is very easy.

Type : Evacuated Glass Tubes.

By the end of the day, the entire quantity of water in the tank reaches the system-designed temperature, provided the radiation level is at minimum of 800 watts per sq.mtr.    

Solar Pool Heating Design Basics   Low pressure is the bottom line when it comes to setting solar up for long term reliability. You can't expect a thin plastic collector to withstand extreme temperatures, thermal movement, aging etc all in combination with stress from pressure in the water. Take away the pressure and you compromise NOTHING. You simply allow the system to operate stress free the way it is intended and you've removed the source for problems. We end up solving other problems in this process and creating a harmonious smooth operating pool mechanical system. Easy to say. Not nearly as simple as you might think to accomplish.   This is our most common solar design for a simple pool without a spa and without "in-floor" cleaning built in where the collectors are elevated up at least one storey. This design requires that the pressure where solar ties in is low. What will a Solar Heater do with my pool Through extensive collaboration with universities and gov't we've learned to simulate the performance of a solar pool heater with remarkable accuracy. We've verified these curves repeatedly with real systems and found excellent correlation. Below is is a typical pool in San Diego CA with a little pool shade, located near the ocean where the collectors are on a south facing roof. Solar Panel Efficiency All products of this style (water flows up the collectors not horizontally and there are about 100-200 flow cores per 4' wide collector) perform exactly the same because they are all the same color and temperature (black and cold) and that's all there is to a comparative efficiency test in this industry. We don't need glass over the collectors because the air is warm relative to collector temperature. If you're comparing collectors based on performance ratings published by an accredited testing agency you're looking at the wrong features. If set up properly we can make any of the 20 collectors manufactured in the US operate almost exactly the same, at top efficiency.

Economic considerations and features   The installation of a traditional street light, whenever the central power grid is not available in the vicinity, implies high investment costs due to installation of cables, excavations, repaving of road asphalt, etc. The installation of Shrinath Engineerings street lights on the contrary is free of these problems, because it has independent energy source and the installation is very simple and easy. Moreover, the Shrinath Engineerings street light is autonomous, ecological, and without operations and maintenance costs, with the only exception of the light bulb which needs to be replaced every 28000 hours. The reliability of this stand alone system is very high as the electricity supply is not subject to interruptions as grid powered street lights are. Furthermore, our Solar Street Light technical design and layout make this street light safe from thieves, and from heavy conditions such as strong winds.   Shrinath Engineerings Street lights all consist of: Solar Module(s) Sealed batteries Cable kit Top pole mounting structure with box for battery and electronics Lamp and Lamp holder SOX Lamp bracket with coupler Technical information for main components The Solar Module is Premier Solar manufactured with high efficiency solar cells assembled and laminated at high temperature on a toughened and tempered glass with high transparency. The module typically has a lifespan of over 30- 50 years. The Regulator is a battery charge regulator with a microprocessor that gives optimal functioning of the street light. Battery charge control with various charge regimes (cyclical, buffer and equalizing charge) in order to guarantee the maximum production and most efficient storage of energy from the solar module. Discharge control ensures optimum performance of the battery, switch off of the lamp if the battery reach a state 75% discharge. Light sensor for the automatic switch on and off the lamps after sunset and automatic switch off at sunrise. "PLUS" function which serves as an automatic increase of lighting time of the lamp in accordance with the amount of energy that the battery has stored. This very important function allows adaptation of the period of lighting, dependent on the actual amount of energy captured by the solar module and stored in the battery during the day. After the standard minimum period of 6 hours programmed, the microprocessor will verify the actual state of charge of the battery and, should it still have energy, it will keep the lamp on for the rest of the night. The regulator has a maximum capacity of 10 Amperes and is equipped with a fuse to protect it from short circuit. It is designed to perform at extreme temperature and humidity conditions and includes a temperature compensation device. It has signals for state of battery charge and eventual fails of the system, and ensures the optimal battery lifetime under all environmental and operational conditions. The DC/AC ballast serves the SOX lamp, transforming an input current at 12 Volts DC into an AC output of stabilized current at high frequency, suitable to power a large light bulb and typically able to guarantee a durability of over 28000 hours. This ballast can be positioned inside the lamp casing. The lamp is made of SOX 18W, 35W bulb, with a luminous flow of 2700 lumens, 5200 lumens. Typically the lamp is installed at about 6 meters from ground and its light generates a 18-20 meter diameter cone of light.

This prototype home employs active and passive solar technologies, including a hidden, roof-top solar water heater, reflective window coverings, and overhangs. Just as solar energy can heat the water for a building, it can also heat and cool the air. Space Heating A solar space-heating system can consist of a passive system, an active system, or a combination of both. Passive systems are typically less costly and less complex than active systems. However, when retrofitting a building, active systems might be the only option for obtaining solar energy. Passive Solar Space Heating Passive solar space heating takes advantage of warmth from the sun through design features, such as large south-facing windows, and materials in the floors or walls that absorb warmth during the day and release that warmth at night when it is needed most. A sunspace or greenhouse is a good example of a passive system for solar space heating. Passive solar design systems usually have one of three designs: Direct gain (the simplest system) stores and slowly releases heat energy collected from the sun shining directly into the building and warming materials such as tile or concrete. Care must be taken to avoid overheating the space. Indirect gain (similar to direct gain) uses materials that hold, store, and release heat; the material is located between the sun and living space (typically the wall). and warming materials such as tile or concrete. Care must be taken to avoid overheating the space. Isolated gain (collects solar energy remote from the location of the primary living area. For example, a sunroom attached to a house collects warmer air that flows naturally to the rest of the house. Active Solar Space Heating Active solar space-heating systems consist of collectors that collect and absorb solar radiation combined with electric fans or pumps to transfer and distribute that solar heat. Active systems also generally have an energy-storage system to provide heat when the sun is not shining. The two basic types of active solar space-heating systems use either liquid or air as the heat-transfer medium in their solar energy collectors. Liquid-based systems heat water or an antifreeze solution in a hydronic collector. Air-based systems heat air in an air collector. Air-based solar heating systems usually employ an air-to-water heat exchanger to supply heat to the domestic hot water system, making the system useful in the summertime. Both of these systems collect and absorb solar radiation, then transfer the solar heat directly to the interior space or to a storage system, from which the heat is distributed. An auxiliary or backup system provides heat when storage is discharged. Liquid systems are more often used when storage is included. Here is a summary of the many different types of active solar space-heating systems: Medium-temperature solar collectors are generally used for solar space heating. Solar space heating systems operate in much the same way as indirect solar water-heating systems, but they have a larger collector area, larger storage units, and more complex control systems. They are also usually configured to provide solar water heating and typically provide 30% to 70% of the residential heating, or combined heating and hot water, requirements. Active solar space-heating systems require more sophisticated design, installation, and maintenance techniques. A very economical, but specialized space heating system is based upon use of transpired air collectors, mounted as an exterior cladding on a south-facing wall. These systems are used for ventilation preheating. This system heats only outdoor air. These collectors are unglazed, and a blower or fan is used to draw air through perforations in the wall to deliver ventilation air into the building. Solar ventilation air preheating systems are generally used in commercial and industrial applications that require large quantities of ventilation air, including: a) buildings that require much outdoor ventilation, such as warehouses, large manufacturing plants, and airplane maintenance hangars; b) crop drying; and c) pre-heating of boiler combustion air. Space Cooling Cooling and refrigeration can be accomplished using thermally activated cooling systems (TACS) driven by solar energy. These systems can provide year-round utilization of collected solar heat, thereby significantly increasing the cost effectiveness and energy contribution of solar installations. These systems are sized to provide 30% to 60% of building cooling requirements using solar, with the remainder usually dependent on TACS fueled by natural gas. The TACS available for solar-driven cooling include absorption systems and desiccant systems. Generally, solar cooling is not used because of the high initial costs of TACS and the solar fields needed to drive them. Solar absorption systems use the thermal energy from a solar collector to separate a binary mixture of an absorbent and a refrigerant fluid. The refrigerant is condensed, throttled, and evaporated to yield a cooling effect, which is then re-absorbed to continue the cycle. Double-effect absorption systems (which use the heat twice in series) are about twice as efficient as single-effect systems, but require significantly higher input temperatures. Because of the high temperature requirements of absorption cooling systems, evacuated-tube or concentrating collectors are typically used. Solar desiccant systems use thermal energy from the solar collector to regenerate desiccants that dry ambient air; they then use that dry air in indirect and/or direct evaporative stages to provide cooled air to the load. The solar heat is used to regenerate the desiccant, driving off the absorbed water. Some systems use flat-plate collectors at intermediate temperatures.
