How a Photovoltaic System Works in Hawaii

If you’re considering a photovoltaic system for your home in Hawaii, you may have a lot of questions — like how can the sun generate electricity for my whole home? Well, there is a lot more to a photovoltaic (PV) system than the sun and solar panels. Like the older systems of electricity that we’re used to, PV systems depend on many moving parts and functions. Learning more about how a photovoltaic system works and how it can affect your home will enable you to make a more educated decision on whether or not this renewable energy source is right for your home.

Believe it or not, photovoltaic has been a source of power since 1890, according to The Synergy Grid. However, it took nearly a century for scientists to understand the process and to develop the technology necessary for harnessing this power. Now, it’s rapidly increasing as a resource for powering homes, businesses and government offices. In fact, it’s so accessible that you can use it to power your home in Hawaii.

Its basic function is to take sunlight and convert it into electricity. This is done through photovoltaic cells, which are small cells that range in size from a postage stamp to several inches across and generate one or two watts of power. While that seems insignificant, these cells are are combined to create PV modules that are several feet long and a few feet wide. From there, the modules are pieced together to form arrays that power a homes, businesses and entire communities of all shapes and sizes.

These cells on photovoltaic systems in Hawaii convert energy into electricity, which is transmitted to different components of the PV system. Most systems include a battery, where extra power is stored and can be used when it’s nighttime or on cloudy days. As you can guess, when it’s not being stored, it’s being used. In addition to these basic parts, a PV system comes with various mounting and assembly parts to maximize its position on a home or business for the greatest possible output.

Once the sunlight meets a PV cell on a system in Hawaii, The Synergy Grid states that it is either reflected, absorbed or passes right through the cell. From there, the energy of the absorbed light is distributed to electrons in the atom of the PV cell. It is at this stage that they become part of the electrical flow. The “built-in electric field” of a PV cell drives the voltage to push the energy through an external power resource, like a lightbulb.

Whether a photovoltaic system in Hawaii is meant to power a small home or a large business, it functions the same. As you can see, the smallest cell is the driving force behind this energy powerhouse. That means that each PV system can be tailored to suit any type of need. With that kind of power and customization, a photovoltaic system is right for any home in Hawaii.
