Common solar terms and what they mean

Common solar terms and what they mean

by | Mar 2, 2021

As more and more Australians choose renewable energy to power their homes, the solar industry is expanding. But often trying to navigate your way through choosing a provider or comparing quotes can be a confusing process.
At Solar System Australia, we want to make it as simple as possible for you to understand how solar energy can benefit your home. And so we’ve compiled this list of common solar terms to boost your knowledge of the industry. We are also always available for a free assessment if you want to tap into our expertise as you choose the best solar solution for your home!

The benefits of renewable energy are many… it is sustainable, clean and uses free natural resources to create – in most cases – no or low pollution energy.
Carbon emissions
When power plants burn coal, they release harmful carbon emissions into the atmosphere. In Australia, more than 30% of carbon emissions generated are from electricity production… and despite our population only making up 0.3% of the global population, we contribute 1% of the world’s carbon emissions.

Carbon emissions are a form of gas that is responsible for the greenhouse effect and detrimental climate change.

The size of a system is made up of the size of each panel and the number of watts it produces. The higher the wattage per panel and the more panels you have the greater the output of the system.

These terms are used interchangeably in the industry. Photovoltaics is the science behind solar… and solar is the common term used in its place.
Polycrystalline
Polycrystalline is a type of solar panel that is created from a blend of multiple silicone sources. Polycrystalline panels are cost effective to produce but aren’t as efficient as other types of solar panels.

Temperature coefficient rating
Solar panels in Australia need to contend with extreme heat conditions. And that’s why the temperature coefficient rating of the panels we use on our homes in Australia is so important.

The temperature coefficient rate is how much energy each cell loses as the temperature rises. A high temperature coefficient rating means that extreme heat will have less of an effect on the panels.

The inverter does the job of converting the DC current to an AC current. And if you have any excess energy, your inverter will feed it back to the grid or into your solar battery unit.
Solar battery
Solar panels can only generate power during the day while the sun is shining. If you don’t use all of the power your solar system makes during the day, and would like to be able to use it to power your home at night, you can install a solar battery.

A solar battery isn’t essential to save money with your solar panels… but it can certainly make a difference!

Roof space
When we talk about roof space in relation to solar, we are referring to the available surface area on your roof to install solar panels.

Obviously, if you have a lot of roof space, you have the option to install more solar panels. But even if you have minimal roof space, you can still reap the benefits of solar with high efficiency panels.

Solar rebates


When it comes to the solar rebate in Australia, the funds available to help offset the cost of your solar system aren’t actually called rebates.
There is a lot of confusion around rebates because they’ve changed many times over the years, so it’s important to get up-to-date information and speak with a reputable company about the financial assistance available to you as a consumer.
Small-scale Renewable Energy Scheme
The Small-scale Renewable Energy Scheme was established to help the government reach their renewable energy targets through the installation of renewable energy systems, including solar.

In the case of the latter, you will receive a feed in tariff which comes in the form of credit on your power bill.
Feed in tariff rates aren’t a fixed amount so you can shop around energy companies to get a good deal.

However, businesses that want to become a Clean Energy Council Approved Solar Retailer are required to comply with a strict code of conduct and commit to solar industry best practice. There is a rigorous application process with regular reporting and check-ins to retain the Approved Solar Retailer status.
Clean Energy Council Accredited Installer
Clean Energy Council Accredited Installers are electricians who are certified and trained in the best practice design and installation of solar systems.
All Clean Energy Council Approved Solar Retailers must only use Clean Energy Council Accredited Installers for their solar installations.
