Ultimately the simple answer to the question “what do solar panels do?” is to convert sunlight to energy that you can use in your home. But to understand how solar power can truly help you save money it is important to know a bit more about what solar panels do and how they do it.
Solar panels in and of themselves are only one part of a system that can convert the sun’s rays into usable power for your home. This power is only limited by the number of solar panels you have, the amount of sun your area gets, your system’s ability to store that power, and your ability to use it.
Solar panels are the most important component of your solar powered system; these panels are responsible for collecting the energy from the sun’s rays, with the use of many smaller solar cells within the panels. When considering the question “what do solar panels do?” think of the way that a sponge collects water as that is the function that these panels serve, the solar cells conducts the light into energy collecting it for use in your home.
The solar panels are placed on the roof of your home in such a way as to catch as much of the sun during the day as possible, preferably a south facing roof that has no trees or mountains to block the sun during any part of the day. While these are the ideal conditions, even a roof that gets 8 hours of sun a day can still provide a fair amount of energy to power part of your home.
Once solar panels collect the energy from the sun, an inverter transforms your energy from a direct current to an alternating current, making it useable to power your home. Once the energy has been converted to power that is usable, it can either be used directly or can be stored in deep cycle batteries for later use. These batteries are the difference between a home that can be independent of the grid and those that must still use power from the power company to power all of their needs.
Now that you know the answer to “what do solar panels do” you will be able to decide whether solar power is right for you and what type of system will be best for your circumstances.
