How Do Photovoltaic Systems Work?

Are you thinking of installing solar panels for your home or business? If you’ve asked around to find out as much as you can about solar systems, you must have come across the term photovoltaics. So, what exactly is a photovoltaic or PV system

Ever since the photovoltaic effect was discovered in 1839, scientists have been working hard to develop an efficient and accessible solar system almost anyone could use. And it worked! PV systems have become a common addition to many homes and businesses and the popularity is ever on the rise.

What is photovoltaics or “PV”?

Photovoltaics or PV systems are the most popular type of solar energy used today. This kind of solar technology converts sunlight directly into electricity through a process known as the photovoltaic effect.  

The cells in a PV system are made up of several layers of semi-conducting materials which serve to capture and contain sunlight’s photons. Here’s how it works: 

  • A photovoltaic cell uses photons from sunlight to detach electrons from silicon atoms
  • The electrons are contained within a pn-junction which works as “one-way membrane”   
  • Negative voltage is created on the surface which faces the sun 
  • A positive voltage appears on the opposite surface
  • An external circuit is used to extract the created electric current from the cell

The more solar cells you have installed, the more energy your solar panels will produce. A standard residential solar panel is made up of 60 solar cells, while commercial panels can range from 72 to 98 cells or more.    

Can I use photovoltaics to power my home?

Installing photovoltaic solar systems for your home brings a myriad of benefits. Not only will you be able to reduce energy consumption and save money, but you’ll also help the environment by reducing your carbon footprint. 

With the constantly increasing efficiency and decreasing costs of PV systems, more and more homeowners are deciding to offset their electrical bills through photovoltaic systems. A grid-tied solar system can be an extremely cost-effective solution since it uses electricity both from the electrical grid and the solar panels and feeds any excess energy into the grid for future use.

What’s more, homeowners with solar panels can sell excess energy to local utility companies, as well as take advantage of excellent incentives, federal tax credits, and rebate programs, all of which make using PV systems even more affordable.    

Can I use photovoltaics to power my business?

Similarly, business owners can greatly benefit from utilizing photovoltaic systems too. If you strive to run an environmentally responsible business and gain greater energy independence, then installing a PV system is precisely what you should do. Here’s what you can get from PV systems as a business owner: 

  • Decrease operating costs: using photovoltaics will enable you to cut down energy expenses significantly by giving you greater control over the energy consumption of your business. 
  • Gain marketing appeal: using renewable energy can give you a great reputation boost, making your business more appealing to ecologically aware customers.  
  • Great federal and state incentives: business owners who go solar are eligible for a number of state rebate programs and tax credits which can greatly reduce the initial costs. 
  • Get energy independence: by using a sustainable and renewable source of energy, you won’t have to worry about increasing electricity rates.
