What Is Solar Energy?

We are sure you know all this but allow us to do our bit.

Solar energy is, simply, energy provided by the sun. This energy is in the form of solar radiation, which makes the production of solar electricity possible. Electricity can be produced directly from photovoltaic, PV, cells. (Photovoltaic literally means “light” and “electric.”) These cells are made from materials which exhibit the “photovoltaic effect” i.e. when sunshine hits the PV cell, the photons of light excite the electrons in the cell and cause them to flow, generating electricity.

An inverter converts the Direct Current (DC) electricity generated by solar panels into Alternating Current (AC), the form of electricity conventionally used in homes. The system is connected through a meter to the grid.

Solar systems allow you to use your solar power when it is generating electricity during the day and put any excess back into the grid. As soon as you need more electricity than your system can generate, your electricity will automatically be supplied from the grid. At night, your house draws energy from the grid.

Solar energy produces electricity when it is in demand – during the day particularly hot days when air-conditioners drive up electricity demand. In use, solar energy produces no emissions. One megawatt hour of solar electricity offsets about 0.75 to 1 tonne of CO2.

The majority of solar PV installations in Australia are grid-connected systems. 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.

How solar Works

How Solar Works?

Firstly, when the Sun is out and shining, the solar panels installed on your roof soak in and convert the energy that sits within its light into Direct Current (DC) electricity.
This happens because, when the photons from sunlight strike the silicone cells in the solar panel, electrons are released. These freed electrons race around and, with the aid of an electric field, create energy in the process.

The electrons then flow through the panel and string, eventually making their way to the installed solar inverter. The inverter, then, takes this energy and converts the DC power from the panels to a usable 240-Volt Alternate Current (AC) electricity.

This AC power is then immediately passed through your house electrical network, and, as it is being generated, it is utilized to operate any household electrical appliances you may have on at the time.

You may be generating more electricity from your solar panels, at any given time, that required and used up to power your home. If that happens to be the case, in most Australian on-grid residential set-ups, the excess power produced by your system is fed back into the grid.

Any electricity that gets fed back in to the grid is power you are essentially selling back to your electricity provider, which means your electricity provider will credit you for it on your power bill. This credit is referred to as a “feed-in-tariff”, and it varies depending on what time of day your systems is feeding excess power into the grid.

Why Go Solar?

Cost Effective

Cost Effective

With the continuous hike in the cost of electricity, it is inevitable for households and businesses to find and implement a cost-effective alternative.

One time investment

One Time Investment

Once the solar panels are installed, the sun definitely won’t ask you to clear a heavy periodical bill. Therefore, all you need to invest in is the set-up cost of the solar panels.

Eco - Friendly

Eco - Friendly

With Australia sourcing around 73 percent of its electricity from coal and 13 percent from natural gas, going solar will substantially reduce greenhouse gas emissions.

Benefits of Solar!

Reduce Your Electricity Bill

Reduce or eliminate your electricity bill and protect against raising energy prices.

Reduce Carbon Emissions

By generating your own electricity you will reduce your reliance on the coal-powered electricity grid.

Clean renewable energy source

Year after year your solar system will continue to deliver free energy from the sun.

Significant return on investment

Start saving from day one. Many systems pay for themselves within a few years.

Increase the value of your home

Many potential buyers and renters are willing to pay more for houses with solar panels installed.

Government incentives

Small-scale Technology Certificates (STC’s) provides big savings towards solar installs.
