SOLAR ON GRID SYSTEM
ON GRID SOLAR:
On-grid solar power system is a solar power generation system where it is connected to the utility grid. The electricity produced by the system is routed to the grid from where it is used to run the various appliances. The installation of the same is also fuss-free and easy to maintain.
WORKING OF ON GRID SOLAR POWER SYSTEM:
- The arrangement of solar modules absorbs the sunlight on them and convert them into electricity. The current generated here is Direct Current (DC). The solar inverter then converts the DC to Alternating Current (AC), thus making it power the electrical items. This electricity is then routed to the grid where it is supplied for day to day use. An important feature is a net meter. It is a device that records the energy supplied to the grid and the energy consumed. At the end of each month, the outstanding is recorded and the consumer is provided with a bill.
SOLAR OFF GRID SYSTEM
ON GRID SOLAR:
Off-grid systems work independently of the grid but have batteries which can store the solar power generated by the system. The system usually consists of solar panels, battery, charge controller, grid box, inverter, mounting structure and balance of systems. The panels store enough sunlight during the day and use the excess power generated in the night.
WORKING OF ON GRID SOLAR POWER SYSTEM:
- Off-grid solar PV systems work on the basic photovoltaic principle, when solar radiations are incident on the solar panel it generates energy in the form of direct current(DC).
- The generated DC energy is fed to the charge controller which regulates the flow of charge and supplies the regulated power to the battery. To supply power during the night or on non-sunny days, batteries play an important role.
- On a sunny day when the solar panel operates efficiently and produces enough power to cater for the load and also to charge the battery, excess energy is stored in the battery and is retrieved later when required.
- The DC energy from a solar panel or battery is converted into alternating current(AC) energy (as most of the appliances at residential/commercial buildings run on AC supply) with the help of an inverter
- This converted AC energy is supplied to the loads connected with the help of the wiring connection.
SOLAR WATER PUMPING SYSTEM
ABOUT:
A solar water pump system is essentially an electrical pump system in which the electricity is provided by one or several PhotoVoltaic (PV) panels. A typical solar powered pumping system consists of a solar panel array that powers an electric motor, which in turn powers a bore or surface pump.
DETAIL:
A solar water pump is an entire water pumping system powered by solar energy through the use of solar photovoltaic panels. It does not use any fossil fuels or external electricity to run the pump.
The pump is a traditional water pump that is generally used for irrigation purposes.
- There are a few components to the solar water pump system, like the solar panel, a motor pump, and a control device to operate it. Some designs may also include an inverter or solar batteries.
- The solar water pump can be used for community irrigation purposes and works well on various water bodies. In-short the solar water pump is powerful enough to replace a traditional diesel or electric water pump.
SOLAR STAND ALONE STREET LIGHTS AND DC SYSTEMS
WORKING OF SOLAR LIGHT:
The solar street lights comprise of, which absorb the solar energy during daytime. The photovoltaic cells convert solar energy into electrical energy, which is stored in the battery. At the nighttime the lamp starts automatically and it consumes the electricity already stored in the battery.
SOLAR LIGHT AND IT TYPES:
There are two types of solar panels commonly used in solar street lights: monocrystalline and polycrystalline. The conversion rate of mono-crystalline solar panels is much higher than their poly-crystalline counterparts. Solar panels also vary in wattage systems.
