SOLAR ENERGY

What is Solar Energy

Australia has the highest average solar radiation per square meter of any continent in the world. More than 2000000  households have solar system on their rooftop. The solar industry is rapidly increasing in Australia. PV panels are being used increasingly, both in the city and in remote locations, to produce electricity for households, schools, and communities, and to supply power for equipment such as telecommunication and water pumps. The majority of solar PV installations in Australia are grid-connected systems. Also, electricity for remote and regional Australian communities has been supplied by solar energy for many years. Australia is one of the sunniest countries in the world and there is huge potential for solar PV to make a significant contribution to electricity generation.

What is Solar Energy

Solar PV System

This technology converts sunlight into electricity using photovoltaic cells (PV cells). This process converts the light into electricity i.e photon to voltage is called photovoltaic cell effect.

These cells get combined with the panels. These panels can be installed at the rooftops, builidings, and vehicles and also can be used for the large scale solar plant across a field.

Solar Inverter

A process in which Solar inverter, or converter or PV inverter, converts the variable direct current (DC) output of a photovoltaic (PV) solar panel into a utility frequency alternating current (AC) that can be fed into a commercial electrical grid or used by a local, off-grid electrical network.

It is an important balance of system (BOS)–component in a photovoltaic system, allowing the use of ordinary AC-powered equipment. Solar power inverters have special functions adapted for use with photovoltaic arrays, including maximum power point tracking and anti-islanding protection

Types of Inverter

 

Stand-alone inverters, used in isolated systems where the inverter draws its DC energy from batteries charged by photovoltaic arrays. Grid-tie inverters, which match phase with a utility-supplied sine wave. Grid-tie inverters are used to shut down automatically upon loss of utility supply, for safety reasons as they do not provide backup power during utility outages.
Battery backup inverters are special inverters which are designed to draw energy from a battery, manage the battery charge via an on board charger, and export excess energy to the utility grid.
