If you are either thinking about buying a solar system, or you already have, then you are probably wondering how a solar system actually works. You may have additional questions and concerns as well; such as has how the solar system works when it is cloudy or rainy outside.

Please read further to find out answers to these questions and many more.

Q: How does solar energy work?

A: While the sun is 93 million miles away from the Earth, it is still a quite mighty source of energy. If you have gotten a sunburn before, you may know about that from personal experience. Solar energy was first discovered by Alexandre Edmond Becquerel, a French scientist from the 19th century. Becquerel witnessed the absorption of light from certain materials, like silicon, in result “knocking” electrons loose. In result of this phenomenon, he developed the first photovoltaic (PV) cell. The PV cell is what solar panels today have to cause electrons to flow in one direction, therefore creating electric currents when coming into contact with sunlight.

Q: How much does it cost to install a solar system with solar inverters?

A: The cost of a solar system relies on several key factors such as where you live, how much do you spend on utilities, and more. The best way to know exactly what you are paying or what you would pay is by consulting with a local solar system professional. One of these trusted experts can provide you with an estimate for how much a solar system with solar inverters would cost for you, as well as how much money you can save each month as they are running.

Q: How do I know if solar energy is right for me?

A: If you own a home, have an adequate roof over your head, and you get a lot of sun throughout the year, you can enjoy collecting solar energy, whether for the science of it all, or for saving money on electric bills. Like the previous answer, it depends solely on where you live and what you pay for electricity, air conditioning, and heat. There is virtually nothing you can lose and much to gain when you invest in solar energy.

Q: Do solar panels work on cloudy days?

A: They indeed do, but they do not collect sunlight as effectively compared to sunny days. The brighter it is outside, the more light that touches the solar paneling, and the more electrons that are generated. On a cloudy day, a solar panel will only generate about a quarter of electricity that it would generate on a sunny day.

Q: Do solar panels work at night?

During the night, the sunlight reflected by the moon is not strong enough to generate any solar energy, so in the sense of collecting more solar energy, it does not during the night time. You solar system, however, will still store and use solar energy that it has collected throughout the day, so it can still be used to power your home, even at night.

Q: How long does a solar system last?

The longevity of a solar system depends on the company that made them, but the minimum that a solar system can last is about 25 years. Keep in mind that you can save money on your utility bills every month, so that is at least 300 months of reduced bills you can have by simply having your solar system installed. Some solar panels even claim to stay up and running for longer than 40 years.
