"Solar Calculator" Android App by ISRO
The energy demand is increasing day by day and the world energy council has indicated increased electricity production from solar energy due to its multibeneficiary characteristics. Government of India has also put a target of generating 175 GW in 2022 through renewable energy. With approximate 300 clear sunny days a year, India has very high solar incidence, which is more than the possible energy output of all fossil fuel energy reserves in India. The solar energy is clean, pollution-free and abundant in nature. The use of solar water heaters, solar photovoltaics, solar power plants are some of the ways to adopt solar energy in our lives. Thus, solar energy is one of the prominent renewable energy on the roof-top of the buildings, mainly in tropical and sub-tropical regions.
Solar insolation is dynamic in nature and changes with time and place. Use of geostationary satellite data (Kalpana and INSAT-3D) makes it possible to calculate the solar insolation varying in spatial and temporal domain. However, use of these data to common man for obtaining all necessary information through a simple android mobile app is envisaged. A synergic use of navigation, communication and satellite technology has resulted in development of an android app which gives solar potential related information for tapping solar energy for residential and commercial usage. The app can be downloaded from “New & Renewable Energy” section at www.vedas.sac.gov.in. This app needs internet connection to calculate the results.
This android app has been developed by VEDAS Research Group / EPSA / SAC at the behest of Ministry of New & Renewable Energy, Govt. of India.
Some of its salient features are as follows:
The app provides solar energy potential (kWh/m2) at any given location
The required location can be keyed in or can be obtained through GPS
It gives monthly and yearly Solar Potential processed using Indian Geostationary Satellite data. It also offers monthly minimum and maximum temperature to calculate realistic solar potential
The location is displayed on image with satellite data in the background.
It also gives azimuth & elevations angles and day length over different time periods in a year. Obstruction of sunlight due to terrain is also calculated using DEM.
It also suggests optimum tilt angle for Solar PV installation
