In urban and rural India, millions of homes and commercial buildings have rooftops that receive ample sunlight during the day. These are ideal for harnessing the sun’s energy by converting it into electric power. This can be done by adding an interface known as an inverter to convert the DC power generated by the solar panels on the rooftop to AC power as most appliances/devices run on AC. Although rooftops can be used for creating rooftop energy sources, there are various factors to be considered before deciding to install solar panels on a rooftop.
Solar Street Lighting is outdoor lighting unit used to illuminate a street or open areas. Solar Street Lights operates from Dusk to Dawn i.e., the lamp automatically switches ON after the sunset and switches OFF after sunrise. These street lights operate in stand-alone mode. The solar street light should be installed in a shadow free area or place where direct sunlight is available throughout the day.
Solar water pumps can supply water to locations which are beyond the reach of power lines. Commonly, such places relie on human or animal power or on diesel engines for their water supply (Omer, 2001). Solar water pumps can replace the current pump systems and result in both socio-economic benefits as well as climate related benefits. The water supplied by the solar water pump can be used to irrigate crops, water livestock or provide potable drinking water.
