The concept of a commercial solar energy system is increasingly gaining mainstream attention, thanks to the prospect of saving thousands of dollars on an annual count. While the idea of harnessing the sun’s energy seemed far-fetched a couple of decades ago, the emergence of new technology and innovation, especially in developing solar panels, has made it feasible for businesses and commercial establishments to use power from a clean, efficient, and renewable source.
In this post, let us talk about how commercial solar power works in the simplest and basic explanation possible.
First of all, be guided that the whole idea of solar energy is turning sunlight into usable electricity by way of solar panels. The technical term is “photovoltaic system,” which by the way is made up of one or a couple of photovoltaic modules. One PV module could contain photovoltaic solar cells from 36 up to 72. These cells play a very important role as they are responsible for converting light into electricity. Accordingly, the PV modules are designed to be connected with each other in a series referred to as “array.” Since PV arrays are created with individual and linked PV modules, the best way to describe photovoltaic systems is that they are modular. Simply put, they are easy to transport and convenient to install. In a commercial solar power system, there’s a huge benefit of having to easily expand in case there is a substantial increase in power requirements.
Arguably the most important component of the entire system is the photovoltaic cell. Although solar power systems wouldn’t work without the panels that are tasked to collect energy from the sun, it is the photovoltaic cell that converts light to electricity. As soon as sunlight comes into contact with the photovoltaic cell, a portion of the light particle called a photon is harvested by the cell. The process of absorption leads to knocking loose from the silicon atom, in turn allowing a positive hole to remain. The freed electron, together with the positive hole, forms a neutral.
In generating electricity, the hole and electron must be separated from each other. Thankfully, the photovoltaic cell comes equipped with an artificial junction layer. Because of this, the freed electrons no longer can return to the positively charged holes. As soon as the electric contacts on the front and rear connect through the external circuit, what happens then is that the freed electrons return to the holes by way of flowing through the external circuit. This is how current is generated. The electrical power can now be extracted from the photovoltaic cell. It has to be proportional to the area as well as the intensity of the sunlight in the same area. Measurement of electricity is in watts.
In a commercial setting, the solar electric system has its brains called the “inverters.” The inverter carries an indispensable role for the entire system to work, just like the solar panels and the photovoltaic cells. What it does is convert DC electricity to AC electricity. The purpose of this is because DC electricity cannot be used in a typical home. The same device also is responsible for monitoring the utility grid and controlling the production of the system. Since it is a highly versatile device, it also is the one that shuts the system down in case there is a power grid or utility blackout.
Although the terms we discussed here are a bit technical for the average business owner, there are a lot of many other references online that will give you more information on the benefit of using solar power systems in a business or commercial setting. This post shows you how the system works, and now it is your responsibility to do more research so as to figure out if it really is a feasible investment to make. You will be amazed at how beneficial a solar power system is, especially if you consider the long-term savings.
