You get solar energy only through direct sunlight. It is the most abundant, pure, non-toxic renewable energy source. There is sunlight every day that shines down on the earth that is 100,000 times greater than the whole world’s power capacity. The sun has always been a potential source of energy, but it wasn’t until the extreme cost rise of conventional energy that people finally took an interest. After more complex ways to use solar energy were discovered, more and more houses are being built that use solar energy as a primary energy source (Heckeroth, 2001). Agriculture has used solar energy in livestock structures to radiate heat into them. Newer, modern solar-powered buildings use their solar technology in the …show more content…
All in all, he invented 500 different devices that incorporated the use of the solar cell. By using a solar battery, he allowed the first plane to fly at night. He owned 200 different patents, some of them in different countries. Lamb was 28 when he invented the first solar cell. Solar cells were used in streetlights to turn independently on and off, using light. The first actual solar panel was invented in 1932 (Fox, 1997).
Photovoltaic modules convert sunlight into DC electricity when sunlight shines on them. Modules are made of glass and either crystal or non-crystal silicon cells. More modules can be added at any time for more power needs. They store all of the energy collected in batteries. Batteries are the only perishable part of a solar system. They are usually lead-acid based and last from five to ten years. A charge controller limits the charge to the battery when it becomes fully charged, so it does not get damaged from overcharge (Fox, 1997).
Active solar heating systems create the highest temperatures. This is because they use liquid heat-transfer fluids. They are easy to fit to most structures, and don’t take up very much room. They can be modified, enlarged or removed if need be. However, they require professional installation and are expensive to buy, run, and repair (Fox, …show more content…
Chlorophyll can be found in chloroplasts of plants, algae, and various bacteria. Its green pigment helps the cells of these organisms perform photosynthesis. The solar cells mimic photosynthesis, which can potentially produce energy (Jenner, 2005). Photosynthesis occurs when light hits organism’s chloroplasts. Chloroplasts are small green molecules in the organism’s cells. The energy from the light is then absorbed by the chlorophyll, which splits water molecules to create a sugar the organism uses for nourishment (Bradford, 2011).
Solar energy is one of the best alternatives. Man has used solar energy for centuries, and solar panels have come a long way. Different systems: passive, active, or dye-sensitized, are not only inexpensive to install and run, but can also help save the earth and money. Solar energy is used for agriculture, homes, and in the city for bigger buildings. Solar panels can be efficient in many ways, and are the product of a better
