Solar Panel Technology Explained
The emergence of solar panel technology dates back to the late 1800's. However, back then it did not receive much interest or popularity. Around one century later, in the mid 1950s, the first "real" solar panel was finally created. Solar technologies started to gain true popularity in the 1970s, due to the growing awareness of the damaging effects of atmospheric pollution and the need for environmentally friendly power-generating systems. Solar panels hardly produce any emissions, making them perfectly safe for the environment, unlike the widely used oil and coal fired electric-generating plants. Currently, solar panel technology is the fastest-growing energy technology in the world.
People were always aware of the sun's power, and it's no wonder. The sun sustains all life on Earth (animals, plants, and humans) and determines the climate. Even though humans have always reaped the imminent benefits of the sun, the advancement of solar panel technology has allowed us to also be able to capture the energy of the sun for future use. Furthermore, solar technology has now become affordable for the average homeowner.
Back in the mid-1950s, solar panels were way too costly and powerless to start using them broadly for residential or commercial applications. However, ever since the 1970s, the technology started to improve steadily and fast. Large environmental interest, dedicated research, and immense investments have resulted in the growth of this industry and the wide availability of solar units.
Now, the solar panel technology has evolved into handy DIY kits, which can be used to power outdoor and indoor lighting, to supply the home appliances with electric, to power the heating of water (pools, hot water systems), and so on. The DIY kits vary in their size, price, efficiency, and complexity. For instance, the small and simple units for solar landscape lighting do not require any assembly, and can be placed where the lighting is needed in the evening hours. The larger kits for powering home appliances, on the other hand, will require the consumer to wire the components together (solar panels, the inverter, battery, etc.), in order to make the system work. Nevertheless, even the assembly-required systems are quite easy to put together.
Solar panels capture the sunlight and convert it to electric, which can be either used right away, or stored in batteries for later use. Most of the currently available solar panels are crafted from semi-conductive silicon, as well as some other semiconductor materials. The panels have a special anti-reflective coating that allows them to trap the sun's energy. The energy is then converted into an electric current, which can be sent either to a battery or to the grid. In order to be efficient, the units have to be mounted in a sunny location, such as on the roofs, polls, etc. The cost of the panels depends on their efficiency and the materials used in their making.
Implementing solar panels involves an initial investment, but it generally
pays off within a rather short time. Solar panel technology is rapidly
advancing, and numerous homeowners have already started using solar
energy for their electric needs.
