With the push for alternative energy sources, solar energy is quickly gaining in popularity. You may be asking, though, how do solar panels work? The leap from traditional energy to solar energy is made easier once the dynamics of the system are understood.
In simple terms, solar panels work by collecting photons from the sun and converting them into DC electrical power. From that point, power is then thrust through an inverter, which transforms it into a basic voltage and AC power. Despite concerns, the strips still work in cloudy conditions as the sun continues to give off enough diffuse light to be absorbed. However, equipment that is directly linked to a panel may not work at full capability. In addition, during winter months, the shorter days will also cause a reduction in input and a snow-covered roof will stop production completely. Regardless of how often your panels draw the sun’s energy, you will need to immediately use it or divert it to a battery as the strip will not store power.

While this method is an excellent choice for alternative electricity, it is not a simple plug-and-go appliance. You can install the panels yourself but if you are not completely comfortable with the process, then it is best to hire a professional. Most companies recommend installing the devices when your roof is being built or re-shingled. This will reduce or eliminate the possibility of water leakage around the posts. It is also far easier to install when you are able to locate the rafters quickly, which is nearly impossible on a covered roof.
More often that not, the benefits of solar energy outweigh the investment and time. Even though they take some effort to install, the yearly maintenance is almost non-existent. Most importantly, however, you will be doing your part to eliminate pollutants and drastically cut greenhouse gases.
