How to connect solar panel to our home electrical appliances

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 Electricity

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…

Difference between Converter and Inverter

Converters and inverters are electrical devices that convert current. Converters convert the voltage of an electric device, usually alternating current (AC) to direct current (DC). On the other hand, inverters convert direct current (DC) to alternating current (AC). Converter                             Inverter                                                                          What it is Electrical devices that convert the voltage from alternating current (AC)…

Steam Turbine Working principle

steam turbine generator is a device that uses steam to rotate a turbine generator to produce electricity. Steam turbines use water that is heated to extremely high temperatures and converted into steam to rotate the blades of a turbine, in order to create mechanical or rotational energy.  This rotational energy caused by the high pressured…
