Learn more in this easy-to-understand article about how to make your own simple solar powered string lights. Solar cells: expose them to sunlight or in fact any light and they…
Solar power is the conversion of energy from sunlight into electricity, either directly using photovoltaics (PV), or indirectly using concentrated solar power. Concentrated solar power systems use lenses or mirrors and tracking systems to focus a large area of sunlight into a small beam. Photovoltaic cells convert light into an electric current using the photovoltaic…
Solar panel : Today we are going to discussing about How much Watts Solar Panel will be Suitable for Home Electrical appliances? We can find it by very easy and simple example and explanation. Suppose we want to power up 6 lights of 15 Watts and we need to use these 6 lights for 4 hours every day….
Solar Cell Manufacturing Technology There are different types of solar of photovoltaic cells available in the market. Each of them has its own technical and commercial advantages as well as disadvantages. The solar cells are mainly categorized on the basis of the materials used as semiconductor in the cell. Different types of solar cell have different technical parameters but they can…
Solar Electricity When sunlight strikes on photo-voltaic solar cells, solar electricity is produced. That is why this is also referred to as Photo Voltaic Solar, or PV Solar. Principles of Solar Electricity Generation of electricity by using solar energy depends on the photo voltaic effect. In photo voltaic effect, semiconductor p n junction produces electric potentia when it is exposed to sunlight. For that…
