“…Solar imperative is both urgent and feasible to enable the country to meet long-term energy needs. Digital solar energy atlas is essential to locate solar energy conversion systems such as solar PV or thermal power plants 7 . A monthly solar radiation map on spatial scale is demand of the present time to locate solar energy conversion systems to produce natural and eco-friendly energy.…”

Quantification of assured solar energy potential is essential to select locations for solar photovoltaic, thermal power plants and to quantify solar power potential. The use of remote sensing observations from geostationary satellite sensors is ideal to capture space-time variability of surface insolation. The annual clear solar energy exposure over India was determined using three years' insolation data at 8 km spatial resolution from Kalpana-1 satellite. High density solar energy pockets were diagnosed in western, central and southern India including Gujarat, Rajasthan, Madhya Pradesh, Karnataka, Tamil Nadu and Chhattisgarh states with annual solar energy exposure ranging from 2500 to 3500 kW h m -2 yr -1 .Keywords: Geostationary satellite, renewable energy, remote sensing.THE over-consumption of the available conventional energy resources in the past few decades has brought to light the threat of energy crisis due to depleting nonrenewable energy sources and increasing population. Moreover, it has also deteriorated the quality of the environment. The use of alternative forms of energy such as solar, wind, ocean, thermal, biomass, geothermal, hydro and tidal energies reduce our dependency on fossil fuels and serve better to complement national energy security 1 . Among these, solar energy can be a good alternative and renewable energy source to fulfil the current energy needs. Advancement in solar radiation technologies is paving the new way in energy sustainability 2 at global (continent) to local (village) scales. Solar energy data is a fundamental input for power generation potential through photovoltaic systems, solar collectors for heating, solar air conditioning, climate control in buildings and passive solar devices 3 . India being a sub-tropical country has vast potential of solar energy compared to its total energy consumption in a year 4,5 , especially in urban and rural sectors. Till date, solar energy is under-utilized in India.It currently accounts for only 0.8% of total power generation capacity in India 1 . The Jawaharlal Nehru National Solar Mission (JNNSM) is a major initiative of the Government of India and state governments to promote ecologically sustainable growth while addressing India's energy security challenges. It also constitutes a major contribution by India to the global effort to meet the challenges of climate change. On launching of India's National Action Plan on Climate Change on 30 June 2008, it had emphasized a graduated shift from economic activity based on fossil fuels to one based on non-fossil fuels and from reliance on non-renewable and depleting sources of energy to renewable sources of energy, specifically to develop solar energy as a source of abundant energy to power our economy and to transform the lives of our people.The objective of the solar mission is to create conditions through rapid scale-up of capacity and technological innovation to drive down costs towards grid parity. The mission anticipates in its three phases to grid cost achieving grid parity for solar...

“…in North America (CCSC, 2013); New York (SEL, 2013; CUI, 2010) as well as with advanced tools such as online interactive maps, satellite-based, climatic and topographical data (Perez et al, 2002;Janjai et al, 2005;Gastli and Charabi, 2010) accompanied by LIDAR scanning of building typologies from air (Redweik et al, 2013) and high-speed computer processing (Lukac and Zalik, 2013;Jakubiec and Reinhart, 2013), which may yield highly accurate solar resource maps of the buildings. This kind of highly sophisticated approach is not considered in our study, as they are less applicable to developing countries, or with emerging economies, which have limited access to such tools.…”

RESUMENCon el fi n de promover el uso de la energía solar en las ciudades, se presenta una metodología de catastro urbano del consumo energético y captación solar, aplicada para distintas tipologías residenciales, categorizadas por manzanas, en Concepción, Chile. La categorización se realiza mediante encuestas, registros socioeconómicos, fotos aéreas, tipologías de edifi cación y simulaciones, que se implementan en un Sistema de Información Geográfi co (SIG). Se identifi can rangos y zonas, que entregan como primer resultado, una distribución diferenciada de consumos y potencialidades solares, que constituyen la base para implementar una matriz de energía renovable. El estudio muestra que en Concepción los sectores de alta densidad presentan menor potencial de captación solar, y los sectores con baja densidad muestran un sobrepotencial, que permitiría alcanzar un equilibrio en la matriz energética solar de la ciudad, mediante la transferencia entre los sectores.Palabras clave: Energía solar, consumo energético, mapas urbanos, tipologías residenciales, Chile. ABSTRACTWith the aim of promoting solar energy use in cities, this paper presents an urban assessment of energy consumption and incident solar radiation, applied to different residential typologies, categorized by block in Concepción, Chile. The categorization was done through surveys, socioeconomic records, aerial photographs, building typologies and simulations, which were implemented in a Geographic Information System (GIS). The identifi ed ranges and zones give, as a fi rst result, the differential distribution of energy consumption and solar potential, which constitute the basis for implementing an array of renewable energy. This work shows that high-density sectors have less solar potential in Concepción, whereas low-density sectors show a surplus, which could allow achievement of a balance in the solar energy matrix by energy transfer between sectors of the city.
