What You Need to Know About Photovoltaic Solar Panels

solar-cells-191691_1280When people talk about solar panels they are actually denoting solar photovoltaic panels that generate electricity. Not all panels produce electricity —some panels produce just hot water and these are called Solar Thermal Panels. But that’s not the topic that we will be discussing today so let’s go back to the main topic — PV Solar Panels.

Present-day photovoltaic cells are built with a Thin-Film Solar Cell (TFSC), also known as Thin-Film PhotoVoltaic cell (TFPV), technology. These solar cells are made by placing one or more thin layers of photovoltaic material onto a substrate. TFPV cells are generally characterized according to the photovoltaic material that is used. Some of the resources used in photovoltaic manufacturing are Amorphous silicon (a-Si), thin-film silicon (TF-Si), Cadmium Telluride (CdTe), Copper indium gallium selenide (CIS or CIGS), Dye-sensitized solar cell (DSC), and other organic solar cells.

Wind Energy Facts

zhangbei-778936_1280Here are some interesting facts about the wind energy. Learn how long it has been used, how people use wind power to generate electricity, how much electricity is generated, and much more.

  • Wind power is the result when the energy from the wind is converted into other forms of energy.
  • Wind power can be harnessed in various ways: windmills generate mechanical energy and wind turbines produce electricity.
  • Windmills were used in Persia (previous name of Iran) back in 200 B.C.
  • Wind energy is renewable Read More
