About Solar Panels

If you are interested in solar energy and is planning to use solar power to light your home, the first thing you want to know is about solar panels. It is of great importance to understand what solar panels are for they are essential part of any solar photovoltaic systems. As you become familiarize with solar panels, you can also now more about their effectiveness in converting solar energy to electricity.

Mistaken Beliefs on Solar Panels

We all know that solar photovoltaic need sunlight to harness energy to convert it into electric current. People tend to think that during cloudy weather, solar panels do not work for the sunlight isn't present. The truth about solar panel is that they can provide electricity to your home for almost one week without sunlight because most of the solar panels used to power homes are attached with large batteries. The belief that solar panels needs a sunny weather for efficiency is a common mistake. Germany has proven that sunny weather is not required for the solar panels to work. The truth is, solar panels can work with UV light. Even though the weather is cloudy; UV light will not be affected.

Another mistake people believe is that solar panels have high maintenance cost. As solar panels consist of an array of solar cells under the covering of a glass or sheet, they do not require much maintenance. Replacement of component is not necessary since the components are not running or moving. Today, you can buy solar panels with 25 to 40 years warranty. As time goes on, solar panels develop their reliability.

The price of solar photovoltaic is another mistake people take. Many believe that solar panels have high prices. However, a statistics about solar panels shows that the cost is reduced sharply in the recent years. Nowadays, you can purchase solar panels without paying anything by using varieties of schemes. Apart from having free and cheap electricity, solar panels can also add value to your home.

One of the common mistakes people believe in about solar panels is about its repayment period. It was not a misconception but a fact that was only a few years ago. The payback period of solar panels have already lessen due to the decline on their prices and also due to the increase on the cost of electricity. Today, the repayment period is 5 to 7 years. The rise in the cost of fossil fuels around the globe will double the cost of electricity in the next five years. It is not a bad thought after all to use solar panels as alternative for cheap electricity.

another mistaken belief of people regarding the use of solar panels is the cut off of modern appliances at home which consume lot of electricity. Cut off from the national grid is not needed just to use the solar panels. This can provide you with a comfortable environment in your home with modern appliances and cheap electric bills at the same time.

Some Interesting Facts about Solar Panels

As people are becoming more and more aware about global warming and greenhouse gasses, they are showing more interest about solar panels and their use in the production of electricity. The awareness in environment has an essential role in making green energy sources the fastest growing industry worldwide. We have already discussed misconceptions about solar panels above, now it is time to read some interesting facts about solar panels and their use.

Solar panels have sharp declining costs. Not long ago, solar panels have unreasonable prices and too long payback time, but not anymore. This last few years, the efficiency of solar panels have risen up to 22%. Manufacturers are investing money in the research and development of more efficient solar panels. The efficiency of solar panels continues to grow as technology advances.

Selling of unused electricity is possible in using solar panels. Feed-in tariff systems are one way used by governments to pay electricity.

Common questions about Solar Panels

The usual questions on solar panels were already undertaken above. Most people want to know about solar panels and their use, cost and efficiency. Others worry more on the payback period and reliability of solar panels. The topic on maintenance is another concern of people. The truth is that less efforts is just needed for the maintenance of solar panels. And some people want to know if solar panels are safe to use. Solar panels are totally safe since its key part is silicon. Silicon is a main element of sand that’s why it is totally safe. The technology of solar panels does not produce any toxic or leakage of any harmful liquid or gas.

Yet another query on solar panels is their storage. Some people believe that solar panels can store electricity but this is not true. Solar panels can only produce current and you have to attach them to batteries with solar panels to store current.

Before placing solar panels at your home, you have to first be familiarize with them. To acquire reliable data about it, you can check online for details. I hope this article imparted sufficient information about solar panels.
