Solar Photovoltaic (PV) cells generate electricity by absorbing sunlight and using that light energy to create an electrical current. There are many PV cells within a single solar panel, and the current created by all of the cells together adds…
A solar battery can be an important addition to your solar power system. It helps you store excess electricity that you can use when your solar panels aren’t generating enough energy and gives you more options for how to power…
Our sun is the source of all life on Earth, and solar energy is useful to us in many different ways. The sun creates two main types of energy – light, and heat – that we can harness for many…
Solar panel systems are an increasingly common sight on rooftops all across the U.S., but it can be difficult to figure out how big solar panels are and how much they weigh unless you climb up onto a roof. In…
Tons of solar panels installed in the early 2000s are reaching the end of their lifecycles, posing a serious problem for the industry to contend with. On paper, solar energy seems more promising than ever. Solar cells are becoming easier…
Making the transition to solar energy is a great investment. You want to feel confident that you’re installing the best possible solar system for your home. Researching solar panels and brands will give you the information you need to choose…
You may have seen advertisements or had someone knock on your door offering free solar panels. But are “free solar panels” really free? Let’s get this out of the way early “free solar panels” are not really free. There is…
Solar panels, also known as photovoltaic or PV panels, are made to last more than 25 years. Many solar panels installed as early as the 1980s are still working at the expected capacity. Not only are solar panels remarkably reliable,…
Determining where solar panels are made is not as easy as one might think. Seven of the world’s top 10 solar panel manufacturers are based in China, while only First Solar is based in the United States. The two remaining…
A solar cell is made of two types of semiconductors, called p-type and n-type silicon. The p-type silicon is produced by adding atoms such as boron or gallium that have one less electron in their outer energy level than silicon…
