FAQ about solar energy

Solar power is generated when energy from the sun (sunlight) is converted into electricity or used to heat air, water, or other fluids. There are two main types of solar energy technologies:

Solar thermal is the conversion of solar radiation into thermal energy (heat). Thermal energy carried by air, water, or other fluid is commonly used directly, for space heating, or to generate electricity using steam and turbines. Solar thermal is commonly used for hot water systems. Solar thermal electricity, also known as concentrating solar power, is typically designed for large scale power generation.

Solar photovoltaic (PV) converts sunlight directly into electricity using photovoltaic cells. PV systems can be installed on rooftops, integrated into building designs and vehicles, or scaled up to megawatt scale power plants. PV systems can also be used in conjunction with concentrating mirrors or lenses for large scale centralised power.

Solar thermal and PV technology can also be combined into a single system that generates both heat and electricity.

Sun is the major energy resource for earth. At any moment, the sun emits about 3.86 x 1026 watts of energy. So add 24 zeros to the end of that number, and you'll get an idea of how unimaginably large an amount of energy that is! Most of that energy goes off into space, but about 1.74 x 1017 watts strikes the earth. Therefore, it is almost a unlimit energy source for human life. Solar energy has a lot of advantages:

It is a renewable energy source

Typical electricity is generated from fossil fuel that will run out one day. Solar energy is a good alternative to replace fossil fuel as the major energy source because solar power is renewable at absolutely no cost to supply energy infinitely.

Environment friendly

The world pollution is getting worse. Any effort that can reduce the pollution to the environment helps to save the earth. Solar panels are able to harness the energy from the sun and convert it to electricity. Therefore, the use of solar panels is environment friendly. Therefore, solar energy that is harmless to the environment will be the major energy source for future - starting today.

Low / no maintenance needed

Once you have installed the solar power system, it can last twenty to thirty years without major maintenance needed. You may need to do system check once a year, just to make sure everything is performing as it should. Since it requires very minimum maintenance cost, your cost should be minimal.

The Australian continent has the highest solar radiation per square metre of any continent and consequently some of the best solar energy resource in the world. The regions with the highest solar radiation are the desert regions in the northwest and centre of the continent.

Australia's energy resources, including solar energy resources, and the factors impacting on the development and adoption of the various energy resources to 2030 are outlined in the Australian Energy Resource Assessment.

Australia receives an average of 58 million PJ of solar radiation per year, approximately 10 000 times larger than its total energy consumption. However, Australia's current use of solar energy is low with solar energy accounting for only about 0.1 per cent of Australia's total primary energy consumption. The most common use of solar energy is solar thermal water heating. Solar PV systems play an important role in off-grid electricity generation in remote areas.

Electricity generation is increasing in response to government policies, notably the Renewable Energy Target, and as a consequence of the development of photovoltaic and concentrating solar thermal technologies through substantial research and development programs. These include the government's Clean Energy Initiative Solar Flagships Program managed by the Department of Resources Energy and Tourism which has committed $1.5 billion to support the construction and demonstration of up to four large-scale solar power plants in Australia, using solar thermal and PV technologies. The Government's aim is to establish up to 1000 megawatts (MW) of solar power generation capacity.

Geoscience Australia is contributing to this program by providing pre-competitive solar resource prospectivity data and analysis to assist the solar industry and research community. The first steps in this project were to improve the collection of solar insolation data through a collaboration project with the Bureau of Meteorology, to increase their solar monitoring ground station network, and to improve the satellite models base used in collaboration with those ground stations.

For people interested in solar ground station sites across Australia, you can view a map and information on some of the active solar ground stations currently collecting insolation data across Australia.

South Australia now has the most expensive electricity in the world providing a powerful incentive for households to install solar systems.

Carbon and Energy Markets director Bruce Mountain crunched the figures and found South Australia’s power is three times more expensive than in the US and 50 per cent higher than the UK.

According to the Australian Government Bureau of Meteorology, in the past 15 years, the daily sunshine hour in Adelaide is 8 hours. So monthly 231 hours, and annually 2774 hours. For Solar, South Australia has an average of 4.5 hours of Sunshine over 12 months. More in Summer time and less in Winter time.

The price of solar systems has dropped dramatically over the past few years, making it an increasingly attractive option for homes and businesses. The upfront cost of your Solar PV system depends on how much Government incentives are available at the time of purchase, the type and number of solar panels to be used, the type of inverter to be used and if you are chossing a normal grid connect system or battery backup system.

The amount of money your household will save on power bills really depends on a few factors:

- The Feed-in-Tariff you receive from your electricity retailer. You may want to shop around to get the biggest Feed in Tariff from another Electricity retailer

- The energy consumption of your household. Solar panels can only generate electricity while the sun is shining so the households that use a lot of power during the day may attract greater savings than those households that consume most of their power at night. However, you will still receive a feed-in tariff for any excess electricity you generate during the day and export back to the electricity grid.

- The size of your proposed Solar system. The bigger the system the more likely you are to save more money depending on your daily usage.

We have built a Power Bill Saving Calculator for our customers to get a roughly result base on their scenarios.

A feed-in-tariff is the amount the electricity retailer pays you for any electricity your solar PV system generates that you don’t use, and is exported back to the electricity grid into the grid.

Feed-in tariffs will be different in every state and by every electricity retailer.

STCs are a government incentives that help reduce the upfront cost of installing your solar PV system. The value of STCs for your solar system that you receive depends on the size of the system and location of the installation.

To be eligible for the STC's, your solar system must be installed by an accredited Clean Energy Council (CEC). installer.

It really depends how old your current electricity meter is at your premises. Some Meters installed are ready to be connected to Solar whereas older models will have to be changed to a Smart Meter to be able to read how much solar electricity is being exported. If your meter requires changing Greenaus Solar will do all the paperwork for the changeover. It is then up to the Electricity retailer to change the meter for you.

The government rebate for PV Systems depends on the size of PV System you choose, The bigger the system the more rebate will be allocated to you. You can check the government rebate here by providing us with few details.

FAQ About Solar Power System

You should always choose a reputable solar module manufacturer who has a Tier 1 rating and who has an office based in Australia for any warranty issues which may arise. At Greenaus Solar we only use Tier 1 Panels with a solid warranty to ensure you will never be left with a solar system that doesn't perform.

A lot of people get confused about the Tier system and believe the tier rating is based on the solar modules but this is incorrect.

Tier one includes the top 2 percent of solar PV (photovoltaic) panel manufacturers.

A Tier 1 rating is actually based on the Solar Module manufacturer not on the individual modules. To be a Tier 1 company they have to Vertically Integrated, Invest heavily in R & D, have an advanced robotic manufacturing process, have manufactured over 5 years and have bankability which means some of the worlds largest finance providers have financed large projects around the world.
