Power blackouts are common in India and thus, providing continuous supply of power to our surveillance systems is sometimes a challenge. Some of our clients for whom continuous operation of the surveillance system is crucial, have purchased generators to ensure that the system is not disrupted by blackouts. It is economical in the long run if you compare the cost of solar energy to the cost of energy offered by using a diesel generator. The return on investment is much faster. Solar and wind energy are most effective in areas where no or irregular power is available.
In the current era where energy crisis is common, it is a huge achievement to implement a system using renewable energy to its maximum potential. Livedarshan has accomplished this in a project which was carried out for Redi Port Pvt Ltd, where we have utilized solar and wind energy to power an IP-based surveillance system.
Solar energy is the energy derived from the sun through the form of solar radiation. Solar powered electrical generation relies on photovoltaic effect. Photovoltaic is a method of generating electric current by converting solar radiation directly into electric current using semiconductors. See the diagram below to better understand how solar energy works.
Wind generators generate electricity by converting the kinetic energy of the wind into mechanical energy. This mechanical energy is then converted into electric energy using turbines. The diagram below shows how a wind generator works.
In this project, we at Livedarshan have built a wind and solar hybrid power system to provide power to the devices which make up the IP-based surveillance system. This includes 14 IP cameras, a 16 channel N.V.R (Network Video Recorder) and 6 wireless equipments. All of these devices use voltage in the range of 12 to 24 V dc.
During the day, some of the power which is generated by the wind turbines and solar panels is used to charge a big power storage device (i.e. a battery). This device will then be use to power the surveillance system at night.
The diagram below will help you better understand how a wind and solar hybrid power system functions.
The wind and solar hybrid power system is more beneficial than a diesel generator. Diesel generators require 0.28 to 0.04 L of fuel to produce per kilowatt of power per hour. It also produces smoke and noise pollution in the process. Furthermore, due to the continuous increase in fuel prices, setting up a diesel generator is becoming more and more expensive. On the other hand, the costs involved in setting up a wind and solar hybrid power system only consists of the cost of purchasing and maintaining the equipment required (i.e. solar panels & wind turbines). There is no fuel costs involved and if the system is well maintained, it will work satisfactorily for many years.
Our client has benefited a great deal from the wind and solar hybrid power system. Their power costs have dropped immensely after the implementation of this system.
