Solar energy has incredible potential to power our daily lives. Solar energy will be applicable to harvest & to generate electric power by photovoltaic (PV) panels. In applications where electricity is required, it can be a legitimate consideration. Furthermore, solar off-grid PV energy systems have provided a versatile solution for many sectors all over world, especially in rural areas where outage of utility connection is the main problem. Hence, the potential of the off-grid solar PV systems stands out so clearly to compensate for the outage of the utility connection.
A standalone solar photovoltaic street lighting system is an outdoor lighting unit applicable for illuminating a street or an open area. Recent advances in LED lighting have brought a promising opportunity for application in street lighting. Combining LED’s low power, high illumination characteristics with current photovoltaic (PV) technology, PV-powered street light utilizing LED has become a norm in many places. The Solar Street Light comprises one light (luminary) and one battery of lithium Ferrous-phosphate (LiFePO4) attached to the fixture on the top of the Hot Dip Galvanized Octagonal pole. The solar panel capacity is 40 W with an inbuilt battery configuration as 12V 18Ah. The luminary capacity is 15 W. The system provides battery storage backup sufficient to operate the light for 12-14 hours daily. There is an automatic ON/OFF time switch for dusk to dawn operation and overcharge / deep discharge prevention cut-off with LED indicators. The ideal height for installing this light is 3 to 3.5 Meters, which illuminates at least 300 square feet of the domain.
The Solar Water Pump is an innovative pump system devised to utilize the power from the sun during the daytime. The system consists of a submersible pump that runs on power generated from the photovoltaic solar cells and is suitable for use on bore wells with 100 mm (and above} diameter up to 80-90m depth. The Solar Water pump system can be applied to various water sources such as open wells, rivers, lakes, etc. this is a 24*7 sustainable water supply solution for the rural sector. The solar water pumping system is very manageable in design and easy to operate. It needs no rigorous preventive maintenance. The system is user-friendly and can be accomplished by users with appropriate training. The solar water pumping system is warranted & hence scope of maintenance during the warranty period lies with the supplier.
Solar water filters with filtration; storage & distribution systems ensure safe drinking water (SDW) and contribute to the reduction of carbon footprints by reducing the use of coal-based electricity. Solar Water Filter enables the availability of safe drinking water to improve the health of the students of schools. This filtration system is fully stainless steel excluding pipes. This water filtration unit works on a high flow rate which maintains the efficiency of the UV system & this is a low-maintenance product with no water wastage. It does not change the chemical property of water.
The Evacuated Tube Collector Solar Water Heater system works on a Black Body Heat Absorption Principle. The principle states that black color absorbs maximum heat, more than any other color. The system uses vacuum tubes made of borosilicate glass with a special coating to absorb solar energy. Air inside the gap between two glass tubes is evacuated which results in a high level of vacuum, which acts as the best insulation to minimize heat loss from the inner tube. The black coating transfers this heat to the water. The water on the upper side of the vacuum tube becomes hot and thus lighter, and starts moving upwards in the tank. At the same time, cold water, which is heavier, comes downward from the tank and is stored at the bottom. This phenomenon is called as natural thermosyphon circulation, which occurs in every tube.
A solar cooker is a device that uses the energy directly to heat, cook or pasteurize drinks. The parabolic solar cooker can save 10 LPG cylinders/year and 80-90 liter of kerosene. Solar cooking does not emit any smoke, unlike other conventional fuels, which help to retain a higher percentage of protein, Riboflavin, and Vitamin A & C there-by, food cooked by a solar cooker is healthy. Vitamins and minerals increase the nutritional value while antioxidants protect against cancer. If solar cookers are used then 2 trees, per solar cooker per year can be saved. Today, solar cookers are widely used and continue to grow in popularity. People are moving away from other fuel sources such as wood, coal, or natural gas because of their harmful by-products and unavailability.
The Solar Study Lamp is the scheme of the Ministry of New & Renewable Energy, Government of India for the distribution of 7 million solar study lamps for school-going children in the States viz. Assam, Bihar, Jharkhand, Uttar Pradesh, Maharashtra, and many more where household grid connectivity is less. A Solar Study Lamp is a lighting device consisting of PV Panels & LED light which are placed in suitable housing. The Solar Study Lamp is especially suitable for study purposes.
