How to assemble a small photovoltaic (PV) panel using readily available materials.  Materials Needed Solar Cells : These are the core components that convert sunlight into electricity. You can buy individual solar cells online (e.g., monocrystalline or polycrystalline cells). Plywood or Acrylic Sheet : For the base or backing of the panel. Clear Acrylic or Glass Sheet : To protect the solar cells while letting sunlight through. Bus Wire and Solder : To connect the solar cells electrically. Tinning Wire : For easier soldering. Junction Box : To house electrical connections. Silicone Sealant or Epoxy : To secure and weatherproof the panel. Multimeter : To test voltage and current output. Tools : Soldering iron, wire cutters, screwdriver, and a drill. Steps to Make a Solar Panel 1. Plan Your Layout Decide how many solar cells you’ll use. Each cell typically produces about 0.5 volts, so for a 12V panel, you’d need around 24-36 cells (depending on their efficiency and your design). Arra...

The visible and near visible (Ultra-Violet and near Infrared) electromagnetic radiation that is emitted by the Sun is termed as Solar Radiation . The solar radiation has a spectral or wavelength, distribution that corresponds to different energy levels, short wavelength radiation has a higher energy than long wave length radiation. These solar radiation convert into useful forms of energy such as "heat and electricity", using a variety of technologies. The technical feasibility and economical operation of these technologies at a specific location depends on the available solar radiation or solar resource. Photovoltaic Effect :- Photo-voltaics are the technology for conversion of solar radiation (sunlight) directly into electricity. A photo-voltaic cell also called a PV or a solar cell is the device used for this purpose. The PV technology has  emerged as a promising technology to generate electricity for small applications like lighting and meeting other electric...
