Bakeries using solar energy to reduce electricity cost
With cost of fuel and power increasing day by day Indian bakeries are looking for alternative energy solutions to cut down their fuel as well as electric energy cost . Fuels used in bakeries are LDO /HSD/CNG/LPG/Furnace Oil /Electricity .
All bakeries requires hot water to clean the utensils used in production process as fat is a major ingredients in bakery product .Utilities run on these fuel for heating water are Hot water generators , Boilers or Hot water geysers . Even at large bakeries the employees canteen consumes large amount of hot water for utensil cleaning . Solar water heating gives these bakery an alternative source energy for heating water and reducing cost of fuel .Temperature attained for such applications could be between 55deg C - 60 deg C
The payback period for such investment could be something between 18 -24 months depending upon the consumption .Many companies like Britannia has installed solar water heating system for its hot water requirement .The most popular supplier of such system is Tata -BP Solar India Ltd .
Other application for usage of solar energy for the larger bakeries have been the lighting around the factory through photo voltaic s cells .
Major advantage of solar energy are
* Lower maintenance cost * Clean environment * Available in abundance all around the year excepts for some region * Save energy cost by reducing either fuel or electricity cost . * No storage space required for fuel .No logistics
