An educational text from the Solar Shop Australia Solar Academy
Introducing Solar Shop Australia At Solar Shop Australia, we believe that by sharing knowledge, everyone can feel connected with their energy and feel good about where it’s coming from. That’s how we started over 10 years ago—before solar was so popular! Since then, Solar Shop Australia has become one of Australia’s top national solar retailers. To this day, we are specialists—solar is all we do. Our renewable energy advisors are available in-store and for free in-home consultations. They are trained to work with you, your energy usage and your lifestyle to design a system that can reduce your bill or even earn you an income through solar energy! They’ll also stick with you during the whole process to guide you through rebates, tariffs and financing. Read on to learn more about going solar. We hope by the end, you too will believe in what we call ‘the power of good’.

Solar Academy Hi, I’m Professor PV. I started with Solar Shop 10 years ago, researching all over the world for the best solar technologies for Australian homes. Now I help run the Solar Shop Solar Academy, which we created to reinforce our passion for solar power and to help Australians learn about home solar energy solutions.

What is electricity? The first law of thermodynamics tells us that energy can be neither created nor destroyed; it can only change form. The sun sends out energy as electromagnetic radiation. This energy, in turn, creates wind, weather, waves and helps plants grow (the original source of coal-powered electricity). Nearly all of our energy originally comes from the sun! Solar cells act as semi-conductors which, along with some other components, convert this energy into an electrical current. A device called an inverter then converts direct current (DC) from the solar panels into alternating current (AC)—which is what we use in our homes. Electricity is simply a flow of electrons, or current, that travels via a conductor from a negative terminal to a positive one. This flow produces heat and light (measured in watts), which is used in homes and businesses. There is enough solar energy for us all to create enough clean, renewable electricity for all our domestic and commercial needs.

Good ‘Good’, or renewable, energy comes from a variety of sources. This is done by harnessing natural resources such as solar, wind, hydro (water), and geothermal (heat from the earth) to drive turbines to create electricity. All of this happens, of course, without the damaging side-effects of burning fossil fuels. Advances in solar system design now make home generation viable.
The other 99% comes from unsustainable resources like coal and oil.

Panel technology choice These days there are four main solar panel technology types. Panels vary in size, appearance, the amount of electricity they generate, their ability to tolerate shade or heat and, of course, their cost. The better the panel, the more power it will output per m2. Solar Shop Australia understands all these technology types, and can design a home energy solution best suited to your individual needs.

System design Solar Shop Australia has more than 10 years of experience designing systems for our customers through all the changing technologies and Government regulations. This experience has enabled us to develop our own unique system design tool (we call it Solve) that helps you make the right choice for your individual needs. If you want, a Renewable Energy Advisor will consult with you about the specifics of your situation—and come out with the best system that suits your needs and budget.

Power Output Guarantee Because every home is different, no two solar systems will be the same. Different technologies deliver different power outputs in different conditions—and the technologies cost different amounts. Since we started, Solar Shop Australia has researched a range of panel and inverter technologies so that we can get the maximum power output in any situation. With a system design from one of our Renewable Energy Advisors, you will see the power output from your system. You can count on your system delivering consistent results well into the future. We only select reputable, stable manufacturers with industryleading warranties, and our customer service team will support you well into the future.

Maths of going solar
A solar system can save you money, and new financing options put you—not big energy companies—in control of your energy bill.

Take charge of your electricity Energy prices are predicted to rise 15% every year across Australia. Installing a solar system will not only save you money in the long run, but also can reduce your bill from the first day it’s installed. Because Solar Shop Australia offers customers $0 deposit financing for a solar system, it can cost you nothing up front (and repayments are generally lower than your current power bill).
This solar thing just makes sense, huh Sunny? Mum and Dad are already paying more than they would with solar!

This graph shows both the immediate and long-term benefits of solar finance, including the option to pay $0 up-front! The red line represents the predicted rise in electricity costs. The green line represents your low solar repayments plus the much-reduced bill you receive from your power company. See how it starts out less than the current energy cost? This shows that you can invest in solar and reduce your fortnightly costs straight away! Plus, your money goes toward a long-term, sustainable energy source for your home. The bigger your system, the shorter your payback period can be. Once you’ve paid your system off, you’ll enjoy years of ‘free’ power!

Why NOW is the time for solar! State Government feed-in tariffs Every state has legislated feed-in tariffs (FITs) that make big electricity companies pay those contributing solar energy to the grid. This means the producers of ‘bad’ energy have to pay ‘good’ solar energy generators (like you) for power. FITs vary from state to state. However, these

tariffs are being wound back as we reach target levels of legislation, so act now to lock in your rate for years to come. Federal Government rebates To support the uptake of solar, and help
meet the target of 20% of Australia’s energy coming from renewable sources by 2020, the Federal Government has created tradeable certificates for anyone buying a home solar energy system. These small-scale technology certificates (STCs) are like shares; they can be sold or traded. Initially, the government has applied a multiplier to increase the value of these certificates for small home solar systems. However, the multiplier is reducing each year until 2013.

the Maths of going solar
We make it easy for you to take charge Generating electricity from your home solar system is very empowering. However, to benefit from state government feed-in tariffs (FITs) and to access back-up electricity for the non-daylight hours, you need to connect to the main electricity grid and get a smart electricity meter. Solar Shop Australia helps you with this process. We do all the chasing around and paperwork for ‘permissionto-connect’ approvals. We now also have the ability to install your ‘smart-meter’ and connect you to the electricity grid.

The power of good people We’re just as excited about solar today as we were when we started 10 years ago. Perhaps that’s because the ‘power of good’ goes beyond feeling great about your free electricity— it’s also about reducing your carbon footprint. To keep the good feeling going, Solar Shop Australia continues to support other organisations that believe in the power of good. We donate solar systems to clients of Habitat for Humanity, we are one of the major supporters of Sustainable House Day, and we are also the only solar company in Australia to be endorsed by Planet Ark.

2345 kg carbon dioxide (CO2 ) saved This publication was printed carbon-neutral under an ISO 14001certified EMS with vegetable-based inks on Australian paper made from 100% post-consumer recycled waste (such as paper from kerbside recycling). Sustainable production methods used for this booklet have saved approximately 2345kg of damaging greenhouse ( CO2 ) emissions compared to conventional production methods. That’s approximately 1.5 times the amount produced by an average Australian home in a month (without solar, of course)!
