Segment OverviewDefinition:Solar power is electricity generated from the levels of natural energy contained within the suns rays. Solar energy is commonly known as solar radiation, and contains a significant amount of energy we are able to harness. The suns rays contain photons. These photons are capable of transforming electrons into conduction electrons, which means they are able to carry an electrical charge.There are two types of solar power:1 ‐ Photovoltaic (PV) is the technical word for solar panels that create electricity. Photovoltaic material, most commonly utilizing highly‐purified silicon, converts sunlight directly into electricity. When sunlight strikes the material, electrons are dislodged creating an electrical current which can be captured and harnessed. The photovoltaic materials can be several individual solar cells or a single thin layer, which make up a larger solar panel.2 ‐ Solar Thermal electricity technologies (also called concentrating solar power, or CSP) produce electric power by converting the suns energy into high‐temperature heat using various mirror configurations, which is then channeled to an on‐site power plant and used to make electricity through traditional heat‐conversion technologies. The plant essentially consists of two parts: one that collects solar energy and converts it to heat, and another that converts the heat energy to electricity.
Segment OverviewBenefits: Solar energy is a renewable resource. Although we cannot utilize the power of the sun at night or on stormy, cloudy days, etc., we can count on the sun being there the next day, ready to give us more energy and light. As long as we have the sun, we can have solar energy. Solar energy is non‐polluting. Of all advantages of solar energy over that of oil, this is, perhaps, the most important. The burning of oil releases carbon dioxide and other greenhouse gases and carcinogens into the air. Solar cells require very little maintenance (they have no moving parts that will need to be fixed), and they last a long time.Downfalls: Some disadvantages of solar power are economic in nature. At present, solar panels designed to generate electricity are fairly expensive to produce. Since a single solar panel can only generate a relatively small amount of electricity, an expensive and bulky array of solar panels would be needed to provide a sufficient level of electricity for homes or buildings. These solar panels also have to be adjusted throughout the day in order to maintain a direct angle with the sun. Indirect sunlight is only marginally better than no sunlight at all, so a mechanical orientation system would also need to be implemented to turn all of the solar panels. An entire field filled with mirrors could focus the suns energy on a power generator, but maintenance of such a system would be prohibitively expensive. Perhaps one of the most noticeable disadvantages of solar power is the sheer volume of solar panels needed to generate very little energy.
