Yes! Rest assured, Steadfast Solar as a company as well as each installer and designer is a Solar Accreditation Australia (SAA) and NETCC (New Energy Tech Consumer Code) accredited installer. This essentially means that we have paid for and completed all courses and training modules required to achieve accreditation.
This is often an extra year of study and experience on top of a general A-Class Electrician apprenticeship or qualification, and longer for emerging technologies like battery storage. Companies who have a poor reputation from numerous audits/reviews, or who perform unethical, dangerous and non-compliant workmanship, eventually lose their licence or accreditation.
Yes! Every Solar Adelaide installation team has at least one fully qualified Solar Accreditation Australia (SAA) and NETCC (New Energy Tech Consumer Code) accredited designer, solar installer and electrician.
They complete all the sophisticated wiring and critical tasks, sign off on the job, staking their reputation and licence on the work they have completed. They can often be supported by experienced solar roof labourers, who assist in placement of panels and rails, but aren’t involved with the electrical side.
It is also common for senior electricians who are adding solar qualifications under-supervision or apprentice electricians who hope to move into solar or renewables, to make up other members of a team.
The solar modules are supplied with a manufacturer's product warranty and peak power warranty.
Steadfast Solar may, at its discretion offer one of the following remedies in the event of a successful claim against the module performance warranty:
1) to replace the defective module/s
2) refund the percentage of the cost of the module to the customer representing the percentage of the power output less than 80% of the nameplate power rating.
In South Australia, we endeavour to but are not bound by its commitment to rectify any fault within 14 days of notification.
It's as simple as, solar system's panels on your roof = generating free power from the sun, all day. This means everything in the home can be powered for free, so you’re not buying any power from the grid while your system is making power instead, and more than half of your bills are gone because you’re not buying any power from the grid most of the day.
That’s only half the story though. A good quality solar system, installed by an expert designer and with enough panels, can make 4 or 5 times more power than you need in the middle of the day.

Steadfast Solar Adelaide has calculated 5 years as the payback period, or the amount of time it will take for your solar panels to pay themselves off.
This calculation is based on a number of factors, which include the solar system size, the plentiful sunshine available for South Australians, good feed in tariff rates and average electricity rates.
It depends on your energy usage, but for most households, the answer is increasingly yes.
Without a battery, surplus solar gets exported back to the grid at record-low feed-in tariffs, while you still pay full retail rates to import power at night. You're selling cheap and buying back expensive.
A battery flips that equation, store what your panels produce during the day and use it on your own terms after sunset. For most homes, that quickly adds up to hundreds, if not thousands, of dollars saved every year.
And if you own an electric vehicle, a battery becomes even more compelling. Charge overnight from stored solar, and it costs you nothing.
Still need help piecing it all together? Jump on a quick call with our assessment team to talk about solar batteries, and we can answer all your questions and cover things in more detail.
Our experienced team will turn the solar system on to test and demonstrate that everything works and is ready for use, and can demonstrate a shut-down or reboot procedure. You can now have peace of mind that everything is working and you're getting a solar feed.
At the end of an install, our solar experts will require your WIFI network and password to connect your system to the phone app for monitoring, so that you can be updated on your system and so that Steadfast Solar can assist in monitoring for faults and ongoing maintenance services.
It is a regulatory compliance that all new installations and properties have a fixed internet source for both the new smart meter and the system’s inverters. If you do not have a home WIFI service or signal, we must provide you with at least a WIFI dongle with a data plan (optional extra cost if no WIFI).
Your energy plan will be more important or relevant to your savings if you:
Otherwise, the time you use your power (or don’t use it), how much and on which tariff, will influence your savings more significantly than your energy plan.
If you want to save far more money from your solar system, “load-shifting” and “strategic energy usage” can save you 2-500% more than finding a slightly better energy plan. To learn more about it, and take control of your energy savings, check out our blogs and cheat sheets.
