Solar Water Heaters constitutes collectors, storage tanks and backup electrical heating(optional) and with water Circulation Pumps if required. There are primarily two types of collectors in general usage: Flat plate and Evacuated-tube depending on the quality of water. A flat plate collector, the most common type, is an insulated, weather-proof box containing a dark absorbed plate under one or more transparent or translucent covers. Evacuated-tube collectors are made of rows of parallel, transparent glass tubes. Each tube consists of a glass outer tube and an inner tube or absorbed covered with a selective coating that absorbs solar thermal energy but inhibits radiative heat loss. The air is withdrawn (“evacuated”) from the space between the tubes to form a vacuum, which eliminates conductive and convective heat loss. Solar water heating system capacities range from 200 liters per day to 1 lac liters per day and can be used for following applications: Domestic: Homes, Bungalows and Apartments. Commercial: Hotels, Hospitals and Hostels. Industrial: Preheating boiler feed water and Process Industries.

Rugged Street Lights using Solar Power designed to with stand extreme weather conditions operate automatically based on light conditions(DUSK & DAWN) with a multiple day battery power backup. These lights are used for the following applications:               Road Side Lighting Main Roads, Approach Roads and Internal Roads of Colonies. Compound Lighting For In d us t r i a l  Pr e m i se s ,  Aq ua F arm s etc. S ecurity   L ig h t i n g Stock  H o l d i ng  A r ea, Sto rag e Y ard s,  Par k i n g  L ots   etc. G a rd e n  L ig h t i n g Park s,  Fa r m s, W a l k- w a y Li g h t i ng   etc.

In Solar power water pumping systems, the Pump(Surface/Submersible) is powered directly by solar photo-voltaic system for lifting water from an open well, reservoir or tube well for irrigation or drinking water for both human and livestock. These systems require a shadow-free area for installationof Solar Panels, and closed and secured area for a pump controller unit(AC / DC) which consists of a Inverter and VFD connects solar panels and pump. These pumps can lift water from depths ranging between 10 - 90m and discharge capacities range between 25, 000 and 1, 45, 000 litres per day.  Varshini power can power any existing or new pumps either submersible or mono block of any capacity. The operation of these solar powered pumps is more economical mainly due to the lower operation and maintenance costs and has less environmental impact than pumps powered by an internal combustion engine (ICE). These Solar pumps are useful where grid electricity is unavailable and for new installations due to the cost of getting new electricity is almost equal to the cost of a solar water pump.

Agriculture Fencing: This system shall meet the requirement of customer who wishes to protect his crops from domestic animals. The System is suitable for Farms, Aquaculture and Horticulture etc. Security Fencing: This system shall meet the requirements of Customers whose  premises / properties are to be protected against tress-passing  / Thefts / Intrusions etc. Ideal for Residential, Commercial Establishments,   Ware-Houses , Stadiums etc. Animal Fencing: These systems protect villagers residing near Forest from Wild Animals like  Elephants, Bears, Wild Bears etc. High Security Fencing: These Systems are designed to protect from any type of intrusion  besides providing access to detect the type of intrusion with the help of CCTV, High Fidelity Camera, Flood Lights, Auto dialer etc.  Major application being the Defence Establishments, Banks, Government Institutions, VVIP residences etc.

Solar panels produce DC Power from sunlight and converted into alternating power (AC) at desired voltage and frequency, through the use of Solar Inverters or Power Conditioning Units (PCU's). These systems can be connected to the loads either in parallel to the grid (Grid-tied / interactive) or use of energy storage devices i.e; usually batteries (Standalone). This entire unit is collectively called as Solar power pack /system and generally these systems require shadow free roof area of 100 - 150 Sq ft per kWp and exert a load of 1.5kg per Sq ft over the roof.  Varshini Power has got hands on experience in integrating these solar power packs. We have tied-up with leading suppliers / manufacturers with in and outside India for supplying some of the Critical components required for integrating PCU's. Domestic Power Packs: Solar power packs comes as standard kits for homes and small offices/shops for power solutions. These have been designed for simple in use, easy and faster installations with minimal maintenance free operations. These power packs can run Electrical appliances like FTL / CFL lights, fans, TV, computers, small / medium refrigerator and other small loads. Commercial Power Packs: These systems are designed based on the usage and load requirements. These can be standalone or grid tied. In industrial units which have heavy loads like motors, compressors and reactors etc., Solar Photo-voltaic system may not support the entire load. In such a scenario a grid-tied system can be installed with an optimum combination of Solar, grid and DG power can be used. In the case of normal loads like lighting, fans and computers in commercial establishments, offices, a standalone Solar Photo-voltaic system can be handy.
