Profile

Supernova Technologies are pioneers in the manufacture of Off Grid Wind Energy Systems.

Supernova Technologies, manufactures stand alone wind generators with indigenous standard materials, to generate power at low wind speed which is commonly and freely available in coastal, hilly and desert areas. The power can be used directly or by storing it in the battery bank and consuming it indirectly by an inverter.

Wind as the primary source, costs nothing and can be used profitably. There is no need for an extensive infrastructure as required for a grid supply network. Supernova Wind Generator will function where no grid connections are available or where grid staggering is a regular problem.

Wind power is growing fast because it is cheap, abundant, inexhaustible and clean. No other energy source has all of these attributes.

Supernova Wind Generators have been used for :

* Residential Colonies
* Town & Street lights
* Hospitals
* Temples
* Hotels
* Farms
* Dockyards
* Remote Areas and any Other Utilities.

Comparison

Comparison of Small Wind Generator with other sources of Energy.

Models	Small Wind Generator	Electricity Board	Solar System	Diesel Generator
Investment	Moderate Investment	Investment is Variable	High Investment (3 times compared to Small Wind Generator)	Low Investment
Recurring Cost	Low	High	High	Too High
Estimated Pay Back Period	6 Years at Mean Annual Wind Speed of 20 Kmph.	Not - Applicable as other alternatives are compared with supply from the State Electricity Board.	Never comes during life of solar system as its efficiency reduces at the rate of 10% per annum.	Does not arrive on account of cost of consumables is too high.
Recurring Consumption Cost	Low recurring cost for Battery - bank only being 50% less compared to Electricity Board ranging between Rs. 2.00 to Rs. 3.00 per KW.	Rs. 4 to 6 per KW.	High recurring cost for Battery - bank only being 30% more compared to Electricity Board, ranging between Rs. 5.00 to Rs. 8.00 per KW. According to our knowledge, subsidy in solar system is available for irrigation purpose only.	Running Cost Rs.10/-  per KW Maintenance cost is too high.

Evaluation of Small Wind Generator:

        1) Compared to Electricity Board, use of Small Wind Generator is Luxury with economy
                in recurring cost with pay back period which depend upon speed of area of Installation.

        2) Compared with Solar Energy System, it is economical in every aspect.

        3) Compared to Diesel Generator, it is economical in recurring cost.
