Solar power is the conversion of sunlight into electricity, either directly using photovoltaics (PV), or indirectly using concentrated solar power (CSP). Concentrated solar power systems use lenses or mirrors and tracking systems to focus a large area of sunlight into a small beam. Photovoltaics convert light into an electric current using the photovoltaic effect
A Grid-tied Solar Rooftop system is energized by photovoltaic panels which are connected to the utility grid through a bi-directional meter which keeps track of all the power the solar system produces. Any solar energy that is not used immediately goes back into the grid through this meter. The Utility gives credit for the excess electricity received by it and deducts the credits earned from your monthly electricity bill.
The Off Grid Solar System, Power Generated from the rooftop system is stored in a battery bank and then fed to load as and when required. Both types of appliances AC and DC can be connected to this system. The inverters are smart and can optionally use the grid power also to keep the load running when power from solar and battery bank is not enough to cater to the total load.
Street lighting commonly uses high-intensity discharge lamps
Used to Solar modules use light energy (photons) from the sun to generate electricity through the photovoltaic effect
Used to String inverters convert electricity from multiple panels while microinverters convert electricity from a single panel
Used to connected to the home power connection.
