Rukmini Corporation Kolkata, West Bengal

The direct current (DC) produced by the solar modules is converted by an inverter into grid-compatible, alternating current (AC) and fed directly into the grid of the local power company. The amortization time of solar power systems can be significantly reduced by the attractive feed-in tariff schemes of Government authorities. There are many places in the world which are not connected to the public grid. With our stand-alone systems for internal consumption, we provide custom-made, high performance systems for a completely self-sufficient power supply. High performance batteries with automatic charge controllers store unused energy to guarantee reliable energy supply at all times – even when the sun isn't shining on the horizon. Our stand-alone off-grid systems ensure a reliable power supply even when the next public grid is kilometers away. Residential System, Commercial System, Street & Garden Lighting System etc. are some of the main Off-grid products offered by Rukmini Energy Pvt. Ltd..

A Rooftop photovoltaic power station is a system which uses one or more photovoltaic panels, installed on rooftops of residential or commercial buildings, to convert sunlight into electricity. The various components in a rooftop photovoltaic power station include photovoltaic modules, mounting systems, cables, Solar inverters and other electrical accessories.

BIPV offers aesthetically appealing roofs & facades which generate electricity. BIPV combines aesthetics and functionality to harness Solar Energy from the building’s exterior- these can be placed as part of the roof, skylights and facades or as asbestos sheets.

Solar street lights are raised light sources which are powered by photovoltaic panels generally mounted on the lighting structure. The photovoltaic panels charge a rechargeable battery, which powers a fluorescent or LED lamp during the night. Our Solar Street Lighting Systems turn on and turn off automatically and operate from DUSK to DAWN. Our Solar Street Lights are designed to work throughout the night. It can work normally for 3 days even if there is no Sunlight. It stays lit for more than just one night if sun is not available for a couple of days or more. Customized designs with longer autonomy as per customers requirment. Various wattage of LED Lamps are used to give desired output.   Advantages Solar street lights are independent of the utility grid. Hence, the operation costs are minimized. Solar street lights require much less maintenance compared to conventional street lights. Since external wires are eliminated, risk of accidents is minimized.

Radiation from the Sun is collected by a solar collector converted into heat energy which transfers heat into the water flowing through the collectors and then the Hot water is stored in an insulated stainless steel tank. This System is designed to deliver hot water 24 hours a day, without using Electricity. Study shows that use of 100 liters per day (lpd) of Solar Water Heating System can save up to 1530 units of electricity every year and thus the system reimburses its cost within 2 years and assures free electricity bills for the rest of its service life. Besides, it immensely helps us to control pollution. A 100 lpd capacity Solar Water Heater prevents emission of 1.35 tons of Carbon dioxide per year. The systems are based on reliable & most efficient technology and require minimal installation as compared to your savings & comfort.

Solar Power enabled Water Pumps are highly efficient, reliable and capable to lift water even from 100ft below the ground, what to say of wells or reservoirs. The power requirements for running the Pumps are met by the customized Solar Modules which generate electricity. It eliminates the need of diesel generator sets and grid electricity for filling overhead tanks and else. Without doubt, Solar Power based Water Pumps are most suitable for various other applications such as operating Sprinklers and other Irrigational purposes at large. Be it Drinking Water Supply, Deep Well Pumping, Pond Management etc, this unique product will revolutionize the use of water pumps. The system is well equipped with Thermal and Overload protection for long life of the product. The installation process being simple, this unique product is maintenance free throughout the long life expectancy period and a very cost effective tool in modern day Irrigation requirements.
