Solar energy - Essay Example Solar power is the transferring of sunlight into electrical energy, either directly by means of photovoltaic, or indirectly by means of concentrated solar power (CSP). CSP structures utilize â€Å"lenses or mirrors and tracking systems to focus a large area of sunlight into a small beam. PV converts light into electric current using the photoelectric effect† (Chiras, 2009). Thermal mass is any substance that can be utilized to accumulate heat from the Sun. General thermal mass substances consist of ‘stone, cement and water’. In the past, they have been utilized in dry weathers or mild humid areas to keep buildings stay cool by soaking up solar energy throughout the daytime.Agriculture seeks to optimize the storage of solar energy for the yield of plants. Methods â€Å"such as timed planting cycles, tailored row orientation, staggered heights between rows and the mixing of plant varieties can improve crop yields† (Bradford, 2008). Solar sanitization can be u tilized to make salty water drinkable. The initial recorded case of this was taken place in 16th century. â€Å"A large-scale solar distillation project was first constructed in 1872 in the Chilean mining town of Las Salinas. The plant, which had solar collection area of 4,700 m2, could produce up to 22,700 L per day and operated for 40 years† (Chiras, 2009).. Solar water disinfection involves placing plastic polyethylene terephthalate bottles, filed with water, in sunlight for couple of hours. Duration of time differ according to climate and type of weather.... Thermal mass is any substance that can be utilized to accumulate heat from the Sun.

Solar water d isinfection involves placing plastic polyethylene terephthalate bottles, filed with water, in sunlight for couple of hours. Duration of time differ according to climate and type of weather from at least ‘five hours to two days’ in completely cloudy situation. It is a suggestion from the World Health Organization (WHO) as a practical way for domestic water handling as well as protected storage. More than three million people in developing nations apply this technique for their everyday drinking water. Advantages and Disadvantages Solar Energy is uncontaminated, renewable and sustainable, facilitating to safeguard the atmosphere. It does not contaminate the air by the discharge of ‘carbon dioxide, nitrogen oxide, sulphur dioxide or mercury’ into the air
