Technology Behind Solar Panel Based Energy for Home Use

Indiscriminate use of fossil fuel-based energy in twentieth-century post-industrialization in developed countries across the world has played havoc both with our ecosystems and economies. Conventional fossil fuels like coal, oil, and gas provide over 65% of the world's electrical power, and 95% of the world's total energy demands. Fortunately, in recent times rising energy costs have forced the world community to look around for alternative green energy sources, and residential solar panels based energy has emerged as a front runner. Solar energy is gradually gaining big acceptance all over and it will be interesting to get an insight into how residential panels works to generate electrical power.

Solar Panel Constitution and Operations 

A residential solar panels is primarily an assembly of solar cells. Solar cells absorb sunlight to generate electricity and an array of such modules is used to supply power to a building. Chemical compounds of elements largely silicon and boron or phosphorous are very important and critical components of solar panels and are responsible for the absorption of solar radiation from the sun to generate electricity.

Photons in sunlight hit the solar panels and are absorbed by semi–conducting materials. Negatively Charged electrons are knocked loose from their atoms as they are excited. Due to their special structure and the materials in the solar cells, the electrons are only allowed to move in a single direction. Since the electronic structure of the materials is very important for the process to work, often silicon incorporating small amounts of Boron or Phosphorous is used in different ways.

An array of solar cells converts solar energy into a usable amount of Direct Current (DC) electricity. It is interesting to note that out of many types of energy particles present in sunlight, only photons are the ones that are responsible for the generation of electric power in solar panels. It is only when these photons strike the solar cells, negative ions ie electrons are released resulting in the emission of electric fields for eventual generation of electricity.

Quantum of electricity power generated is directly proportional to a number of solar cells in the panel.  Further, best results are obtained from solar cells when placed under direct sunlight away from the buildings, trees, or other obstructions. Shadow effects have to be prevented from the residential  solar panels  sydney to achieve the best results.

Another mechanism to achieve higher output and efficiency is to provide a rotating stand for panels that could follow the direction of the sunlight for the duration of the day. The rotational solar mechanism helps achieve the generation of maximum electricity from the solar panels. The installation of solar panels on a flat roof is also helpful for getting higher electricity output. These configurations help adjustment of the solar cells as needed to obtain most of the radiation from the sun.

Availability of the state of the art residential solar panels sydney systems is motivating many people to design and install solar panels on their home rooftops themselves. On the other hand, many other people are building wind power generators making use of wind power, wherever feasible to generate electricity.
