How Solar Panels Work

The solar panels have become one of the most vital components of the modern day home. The phrase solar panel is commonly used to describe a photovoltaic module fitted into the roof of your house. These panels work by absorbing solar energy and change it into electricity, which is then routed to power your home appliances. Photovoltaic cells or PV Cells are the heart of the solar panels and these need to be carefully installed to maximum efficiency.

There are many components that make up a solar panel and each of these is designed for specific applications. A charge controller is integral to the design of most solar panels made today. This is essentially a circuit board which stores the charge controller current and acts as a switchboard for sending signals to the solar panels. The charge controller is also used to maintain the correct charge level within the system.

There are three types of solar panels, which are available in Australia. These are the crystalline silicon modules, the amorphous silicon modules and the multi media crystalline panels. The crystalline panels are the cheapest of the three and were the first to be widely utilised. They have become increasingly more efficient over the years and have now reached their maximum efficiency levels. As the efficiency levels continue to rise, the price of these panels has also begun to fall.

Another highly efficient type of solar panels is the amorphous silicon modules. These are also fairly new to the market and were initially developed in Japan in the 80’s Although expensive to manufacture, they are extremely effective and have quickly become extremely popular. As with the crystalline panels, they store electricity in their silicon cells. Amorphous solar panels use semiconductor diodes rather than crystalline silicon to store the electricity and are therefore considerably less efficient.

One more alternative to the standard solar panel that can provide a lower cost solution is to build your own solar array. A solar array is simply a series of solar panels that are interconnected through wiring. Most commercially available solar arrays connect four solar panels together to form a fifty-two-watt solar array. If you were to try and build a solar array on your own, you could potentially create a one thousand-watt system. Although this may seem like a large solar array, it is still significantly smaller than most systems that are being used today.

Although the cost of materials and skilled labor is higher than traditional solar panels, they have the advantage of not emitting any carbon dioxide emissions into the atmosphere. A downside to pv panels is that although you can generate electricity for free, it will only be while the sun is shining. When it is time to darken the site, all the photovoltaic cells will stop working and you will need to invest in an additional battery to store the extra electricity. Although they are slightly more costly upfront, they are far more cost effective over time. PV cells are capable of producing electricity even on a cloudy day and they are capable of storing excess energy for future use.
