A PV system that is designed, installed, and maintained well will operate for more than 20 years. The basic PV module (interconnected, enclosed panel of PV cells) has no moving parts and can last more than 30 years. The best way to ensure and extend the life and effectiveness of your PV system is by having it installed and maintained properly. Experience has shown that most problems occur because of poor or sloppy system installation.
A PV system is made up of different components. These include PV modules (groups of PV cells), which are commonly called PV panels; one or more batteries; a charge regulator or controller for a stand-alone system; an inverter for a utility-grid-connected system and when alternating current (ac) rather than direct current (dc) is required; wiring; and mounting hardware or a framework.
When certain semiconducting materials, such as certain kinds of silicon, are exposed to sunlight, they release small amounts of electricity. This process is known as the photoelectric effect. The photoelectric effect refers to the emission, or ejection, of electrons from the surface of a metal in response to light. It is the basic physical process in which a solar electric or photovoltaic (PV) cell converts sunlight to electricity.
What do we mean by photovoltaics? The word itself helps to explain how photovoltaic (PV) or solar electric technologies work. First used in about 1890, the word has two parts: photo, a stem derived from the Greek phos, which means light, and volt, a measurement unit named for Alessandro Volta (1745-1827), a pioneer in the study of electricity. So, photovoltaics could literally be translated as light-electricity. And that's just what photovoltaic materials and devices do; they convert light energy to electricity, as Edmond Becquerel and others discovered in the 18th Century.
Yes! Solar power costs less than traditional power in many markets throughout the U.S. These are the areas where we do business. Traditional utility costs also tend to rise every year. FVES lets you lock in low, predictable solar energy rates no matter how much traditional power rates go up. You can watch your savings grow over time.
Your solar roof will look great! We worked with our manufacturers to make our panels sleek and elegant. The frames are painted with automotive-grade black paint, while our unique mounting system blends them right into your roof. Wiring and other components are hidden from view. It's a distinctive look you'll only get from FV Electrical
Solar panels installed on your roof convert sunlight to electricity throughout the day. Any electricity that you do not use immediately is put into the power grid. This excess energy offsets your energy use at night when the system is not generating electricity. The result is lower utility bills and more control over your energy costs.
There are many factors that determine whether or not solar power will work for you. First, you must own the home where you want solar installed and have high utility bills. Our customers typically spent over $100 per month on electricity before signing up with us.
Other things that could determine if solar is right for you include your roof type, your credit score and the shading on your home. One of our Energy Advisors can go over all this and answer your questions during your free consultation.
Most roofs get more than enough sunlight. Our experts can map your roof and install solar panels where they'll be most effective. Our customers typically generate 50 to 90% of the energy they use every year from solar. This can lead to significant savings since solar energy is more affordable than electricity from the utility company.
We understand that many customers don’t expect to live in their homes for 20 years. That's ok! Solar is a huge plus when it’s time to sell. Berkeley Labs found homes with solar command more at resale than homes without.*
Most customers simply transfer their solar agreement to the home’s new owner. You can also buy out the system ahead of time and include the cost in your home's sale price.
