Frequently Asked Questions
How do solar panels work?
During the day, photons in the sun’s rays hit your solar panels and are captured by the solar power modules and solar PV cells. Each PV cell has a top and bottom layer. It creates a small electrical field that captures photons by giving the top layer a negative electrical charge and the bottom layer a positive charge. When the photons hit the electrical field, it causes a reaction that sets the electrons into motion and generates electricity. This tiny but near-instant movement happens over and over, causing DC (Direct Current) electricity to be generated.
Unfortunately, while you can use DC electricity, 99% of modern homes and appliances in Australia use AC (Alternating Current) electricity. So energy generated by your panels must be converted by a solar inverter before it can be used.
How much money can I save using solar?
What size solar panel system do I need?
To determine how to size your solar system, take your daily kWh energy requirement and divide it by your peak sun hours to get the kW power output. Then divide the kW output by your panel’s efficiency to get the estimated number of solar panels you’ll need for your system.
Buy Solar Galaxy panels because we consider your needs, power usage, budget and more to provide you with a solar panel system that will generate the best possible results. We are one of Australia’s leaders in solar power.
Our expert solar engineers and CEC-accredited solar installers can deliver a service that is second to none. Discuss your needs with our team, and we can have one of our residential solar systems with small-scale technology certificates installed on your home in less than four weeks.
What are the environmental benefits of using solar?
Solar panel installation helps prevent harmful greenhouse gas emissions, reducing global warming.
Solar panels emit no pollutants and are thus ecologically benign. They also lessen our reliance on scarce fossil fuels and traditional power sources. Solar Galaxy installs solar panels on residential and business sites and is considered one of the best in the solar industry.
Do I need a solar storage battery?
Unused solar electricity from a solar panel may be stored in a battery and utilized at night or on days with little or no sunshine. There are several advantages to installing batteries, including higher efficiency, improved off-grid systems, the ability to utilise solar power at night, and many more. Batteries aren’t required for a solar energy system to function, but they are an optional expenditure that may increase the system’s worth.
