a) Photovoltaic solar power systems are environmentally beneficial because they release no harmful pollutants or emissions such as CO2. These systems operate throughout the day‚ implying it is sunny‚ and do not rely greatly on other power sources to operate‚ thus there is less of a toll on the environment in terms of external resource usage. An environmental cost of photovoltaic systems is the manufacturing of these systems that uses energy and could possibly contribute to more atmospheric pollution

world is struggling with power crisis. Because of this‚ many people are searching for ways to overcome this problem. One of the ways is using alternative energy. Alternative energy is renewable energy sources that are usually free and clean. One of them is solar energy. Solar energy can help in generating electricity by converting solar power (sunlight). The solar power can be use in many ways such as providing electricity for home and business buildings. The use of solar power in buildings is still
