Solar PV Panels

Solar Photovoltaic Panels technology (PV) involves the conversion of solar rays into electricity, which can then be fed into a grid or utilized off-grid. Solar PV technology uses arrays of solar cells to receive sunlight and convert the same into electricity. PV Solar panels do not necessarily need direct sunlight, they can function in daylight. Hence, photovoltaic technology can produce some electricity even under cloudy conditions. PV systems connected to the grid require hardly any maintenance

BIPV-Building Integrated Photovoltaic

In BIPV, modules have been integrated into roofing or other building materials as an alternative to traditional PV modules that are mounted above the roof on racks. Once installed, BIPV components protect the home from weather and also produce electricity for use. BIPV systems can be installed on a small scale to produce limited amount of energy or be large enough to power an entire home and send excess electricity to the utility.

CIGS Thin Film Material

CIGS thin film material is a solid solution of copper indium selenide (often abbreviated "CIS") and copper gallium selenide. Thin film is a process where material from a target source is coated onto a substrate via a plasma field. Silicon solar cells use a wafer of Silicon (Si) which is very thick compared to thin films that are just microns thick. CIGS thin films produce electricity for use and also don’t degrade in sunlight like other thin-film technologies

Solar Water Heaters

Solar water heating (SWH) systems is a mature renewable energy technology which has been accepted in most countries for many years. In a "close-coupled" SWH system, there is a storage tank that is mounted horizontally immediately above the solar collectors on the roof. No pumping is required as the hot water naturally rises into the tank through thermo-siphon flow. In a "pump-circulated" system the storage tank is ground or floor mounted and is below the level of the collectors; a circulating pump moves water or heat transfer fluid between the tank and the collectors. SWH systems are designed to deliver the optimum amount of hot water for most of the year.

Solar Light Tubes

Solar Light tubes or Solar Light Pipes are used for transporting or distributing natural light. Generally speaking, a light pipe or light tube may refer to a tube or pipe for:

  • transport of light to another location, minimizing the loss of light;
  • distribution of light over its length, either for equi-distribution along the entire length.

A solar light tube is a tube lined with highly reflective material which leads the light rays through a building, starting from an entrance-point located on its roof or one of its outer walls.

Solar Street Lights

Solar Street light was originally designed for use in less developed or isolated areas, or perhaps places where the electricity supply has been disrupted by man-made or natural disasters. Street lights powered by solar energy can be simply and rapidly installed, giving the potential of many years of trustworthy use, with a minimum of maintenance required. Solar street lighting can be used not only on streets, boulevards and highways but can also provide cost-effective, environmentally friendly lighting for both military and civilian security installations; park areas or parking spaces; airports, docks and similar areas or, indeed, for whole communities.

LED Lighting Systems

Light-emitting diodes (LEDs) lighting systems are solid-state devices that convert electric energy directly into light of a single color. Since they employ “cold” light generation technology, in which most of the energy is delivered in the visible spectrum, LEDs don't waste energy in the form of non-light producing heat. The technology could be a cost-effective option for lighting a home or office space because of their very long lifetimes.

Advanced Glazing and Thermally insulating triple-glazed units

Advanced Glazing and Thermally insulating triple-glazed units are multifunctional thermally insulating units available with Nanogel® aerogel, a translucent form of silica aerogel. With the availability of this technology, building can now be designed with extensive glass exteriors that have an insulation value up from a traditional R-2 to an unprecedented R-17, nearly the same value to that of an insulated solid wall yet it still admits full spectrum natural daylight into a building.

Heat Pumps

Heat pumps deliver heating, cooling and hot water to buildings in the domestic, public and industrial sectors and can be located anywhere in the world as they utilize the constant temperature of the earth, the air temperature or water source. There are three main types of heat pumps: ground source heat pumps, ground water source heat pumps, and air source heat pumps

Air to Air – Heat Recovery

Air to Air – Heat Recovery and demand control systems have been developed for Buildings to attain low-energy ventilation systems. Heat recovery wheels with mechanical ventilation systems have been designed

Ethanol burning stoves

Ethanol burning stoves function like kerosene stoves and can be used for cooking and water heating and is based on an eco-friendly renewable fuel source – ethanol a byproduct of sugar industry.

Biogas based Heat and Power systems

Biogas produced from the anaerobic digestion of animal manure, green crops and other forms of organic waste can be used for heat and power generation. Upgrading can be done to a level compatible with natural gas by cleaning and by increasing the methane share.

Micro-cogeneration system/ Package for heat & power based on Natural Gas

Micro-cogeneration system employs an internal combustion (I.C.) engine technology which is a reciprocating engine cogeneration system. These cogeneration systems have high power generation efficiencies in comparison with other prime movers. There are two sources of heat for recovery: exhaust gas at high temperature and engine jacket cooling water system at low temperature.
