Abstract
ABSTRACT
The present investigation entitled “Assessment of roof top solar power potential in Solan city of
Himachal Pradesh” was conducted during 2017-2018 in the Department of Environmental Science, College of
Forestry, Dr. Y.S. Parmar University of Horticulture and Forestry, Nauni Solan H.P. Solan city was purposely
selected for the study. 4 sectors namely residential, institutional, industrial and commercial were selected. In the
selected sectors building were randomly selected for collection of primary data, and the secondary data was
collected from various government offices. The data was collected regarding the fuel consumption namely
electricity, LPG and petroleum oils. It was found that 56 per cent of the population from selected households
belonged to annual income group of 2 lac – 5 lac. When income was distributed on the basis of family size it
was found that a maximum overall income of Rs. 7,76,736.1 and a minimum of Rs. 1,19,286 came under family
size 6-7 in summer season and less than 4, respectively. The maximum monthly overall electricity consumption
observed was 352.22 kWh in summer season and 505.56 kWh in winter season. The overall number of cylinders
used in summer was 1.34 and in winter it was 3.69. The monthly energy consumption parameters showed that
the average electricity consumption during summer and winter seasons in case of hospital was 647.50 and
662.30 MWh, respectively, in case of bank was 136.29and 182.62 MWh, respectively, for private and
government schools it was525 MWh and 385 MWh, respectively. The overall LPG consumption in intuitional
sector was 3.25 and 7.75 cylinders for summer and winter season, respectively. The overall annual petroleum oil
consumption in the institutions was 2000 litres. The monthly electricity consumption of small and micro
industries for summer was 2,419 MWh and 2,156 kWh and for winters it was 2,610 MWh and 5,120 kWh,
respectively. The annual energy consumption and carbon dioxide emission of Solan city was hence calculated to
be 287.17GWh and 5,49,472.34 tonnes respectively. The annual rooftop solar power potential of Solan city
calculated was 312.08GWh. This study showed that solar power if used judiciously in Solan city, it would be
sufficient to fulfill the energy needs of the city and also to curb carbon dioxide emission in the city due to usage
of non-renewable energy resources.
