Solar PV cells convert solar energy in to electricity that is used to charge batteries to provide lights during night. Solar energy has excellent potential in Pakistan that receives high levels of solar radiation throughout the year. Solar Energy is available at a rate of 1000 watts per square meter in Pakistan. This can be converted to DC electricity with the help of Solar Photovoltaic cells, which may be used to pump water, operate fans, TV and telecommunications directly during daytime. The electrical energy generated during the day time (5-8 hours of sunshine), can also be stored in deep cycle lead acid batteries which can be used at night to provide power for lighting, radio, Television and fans. The system will be user-friendly and designed as a stand-alone system for each household, who will be trained to operate and maintain it. The user will only be required to switch on/off the system, as is done in normal home lighting systems. In addition, Solar Photovoltaic Panels can generate enough electricity to pump water from depth of 350 ft, 700 ft and up to 1000 ft
Solar energy is a potentially available renewable energy source in this region. This source can be utilized as an excellent alternative to fossil fuels for these areas. Solar energy resource is planned to successfully utilize for household applications and electrification of remotest villages of these areas. The outcomes of this program are social uplift, betterment and provision of basic amenities of life.
Resource Potential of Solar Photovoltaic
Pakistan covers 796,095 square kilometers of land between latitudes 24° and 36°north and longitudes 61° and 76° east. At present, it faces serious energy problems: 95 per cent of its electricity generation comes from hydropower, which becomes less productive during the driest, hottest months of the year and cannot keep pace with the sharp rise in energy demand. Also, about 70 per cent of the population lives in some 50,000 villages dispersed around the country. Many of these villages are far from the main transmission lines of the national grid and, because of their relatively small populations; it is usually not economically viable to connect these villages to the grid. Solar energy, on the other hand, has excellent potential in areas of Pakistan that receive high levels of solar radiation throughout the year. Every day, for example, the country receives an average of about 19 Mega Joules per square metre of solar energy
