Solar Water Heater
Solar thermal systems use sunlight to heat water - for domestic use and commercial usage.Flat-Plate Collector (FPC): Glazed flat-plate collectors are insulated, weatherproofed boxes that contain a darkabsorber plate under one or more glass or plastic (polymer) covers. Unglazed flat-plate collectors -- typically used for solar pool heating --have a dark absorber plate, made of metal or polymer, without a cover or enclosure.Evacuated-Tube Collectors(ETC): They feature parallel rows of transparent glass tubes. Each tube contains aglass outer tube and metal absorber tube attached to a fm. The fin's coating absorbs solar energy but inhibitsradiative heat loss. These collectors are used more frequently for U.S. commercial applications.A typical 100 LPD (litre per day) system is sufficient to provide approximately 100 litres of hot water at an average temperature of 65°C every day on all sunny days. This helps save approximately 4 units of electricity daily (equivalent energy consumed by an electrical geyser) offering cost benefits of approximately Rs 4,000 per year. TPS solar water heaters are available in scalable multiples of 100. Large scale installations, for special applications · Quality: Durable and long life (life expectation more than 15 years)· Service: Strong dealer network across country & well trained installation team· Technology: Triplolayered evacuated tube technology for rapid water heating· Better Insulation: Specially insulated storage tanks retain hot water for considerable amount of time, withminimal temperature drop at night· Suited for Indian conditions: Our storage tanks are specially suitable for Indian hard water conditions· Optimum conversion threshold: Higher efficiency· Easier to install & maintain: Makes the system suitable for varied projects.Solar water heaters are available with us in the following sizes: 1. 26021A Non Pressure 100 Liters2. 26021B Non Pressure 150 Liters3. 26021C Non Pressure 200 Liters4. 26021D Non Pressure 250 Liters5. 26021E Non Pressure 300 Liters6. 26021F Non Pressure 500 Liters

solar power plant
Solar energy originates in the depths of our sun. The sun endures a continuous stream of thermonuclear explosions as hydrogen atoms are fused into helium atoms. We encounter the resultant energy as radiation that strikes the surface of the earth. Solar panels convert this solar radiation into useful electrical energy and store them in batteries for our use. Enough solar radiation strikes the earth every day to meet earth's energy needs for an entire year. Solar panels, help us harvest this energy and convert it into usable energy to meet the everyday needs of modern life.WHAT ARE SOLAR PANELS MADE OF?Solar panels are typically constructed with crystalline silicon, which is used in other industries also. Solar Panels are a form of active solar power, a term that describes how solar panels make use of the sun's energy: solar panels harvest sunlight and actively convert it to electricity. Solar Cells, pr photovoltaic cells, are arranged in a grid-like pattern in a solar panel.On Grid Solar Power Plant Available for all Wattage Requirement on Per Wattage Basis.

It consists of number of solar cells arranged and connected in a definite pattern. It converts solar energy into electrical energy when sunlight falls on its surface.Solar Inverter Cum Charge Controller With Intelligent Logic Control:Solar Inverter converts DC (Direct current)power from the battery to AC (Alternating current) power compatible with the utility and AC loads. This unit consists of Solar Inverter cum Charge Controller with Intelligent Logic which controls the charging of battery from solar or mains with solar aspriority.This system monitors the Battery charge status and accordingly decides to charge the battery either from solar or from mains. First priority of charging is from solar modules and only in the absence of solar power (no-sunshine time) and when battery voltage is low (a predetermined level), the mains charger is turned ON automatically. This maintains the battery on float.When battery bank reaches a preset low voltage, mains charger turns "ON" and charges the battery bank. Next day, when solar radiation is available, the cycle repeats. This ensures healthiness of battery and hence the life of the battery gets extended. Battery deep discharge, over charge protections are incorporated inside the Solar Inverter.BATTERYA device that converts the chemical energy contained in its active materials directly into electrical energy by means of an electrochemical reaction. Low maintenance, tubular type batteries are provided with this system.MODELS AVAILABLE500Watt, 1KW, 2KW, 3KW, 5KW, 10KWFEATURES· System designed for optimum performance.· Fully automated operation.· Add-on solar charging system available if home inverter is already installed - increase back-up time and save on power bills.
