Choosing to invest in solar energy for your home is a big decision. That’s why we strongly believe in providing you the best of service; from understanding how solar panels works to the importance of having a good system design and installation for your home.
Learn more below about the steps involved when our Renewable Energy Advisers design a home solar PV system.
Grid Connect vs Stand-alone
A smart grid-connected system
Most residential houses work on a grid-connect system – these systems export electricity to a larger network when excess electricity is generated. Stand-alone systems supply a local load of electricity, usually supported with a battery backup. These systems often incorporate a second power generator, such as a diesel generator and are usually installed where it’s more cost-effective than connecting to the grid network.
Panel Technology Type
Panel technology types vary depending on where you are located. Traditional panels, like monocrystallines will often be chosen when installation space is limited or where frames and installation costs are high. Newer technologies, like thin film, might be chosen where installation space is plentiful.
Solar panels on fixed arrays will generally be oriented towards the north in the southern hemisphere. This will expose the panels to the greatest amount of sunlight through the course of a day. East facing arrays will receive morning light, and west facing arrays will receive afternoon light. Arrays might be faced east or west so that power generation matches the times when loads are expected to be high.
The tilt of an array will impact the time of year that the solar panels receive the most sunlight – a flatter installation will receive more sunlight in summer, and a more extreme angle will receive more sunlight in winter. Positioning an array to the installation site’s angle of latitude will expose the panels to the greatest amount of sunlight over a year.
Your current energy usage
Many of our customers start considering solar power due to their escalating power costs. One of the biggest influences on your system design is your current electricity use. It’s a good idea to check your average monthly use before contacting us so that our advisers can give you a better idea of what you need.
The amount of space available
Each panel technology type have differing energy generation capabilities. Your Renewable Energy Adviser will work with your current roof area to develop the optimum solution for you.
STC rebate zones
Different locations (eg: Melbourne vs Townsville) have different levels of sunlight throughout the year. It is the average potential output of the system across the year that will provide you with the greatest benefit from going solar. Specific areas within Australia are categorised into different zones of solar radiation (the zones also determine the number of STCs you will receive).
Solar generation supply and demand
We’ll also talk to you about your budget and whether you’re aiming to reduce your electricity bill, eliminate it or try and make money. When meeting our Renewable Energy Advisors during you free in-home consultation, they will consider YOUR individual needs and circumstances.
