Frequently Asked Questions

If you’ve got any questions about solar, we’re here to help! We’ve compiled a list of our most frequently asked question for you. If you have any questions that aren’t listed here, please feel free to email us at hello@solarkraft.com.au, or call us on 1300 985 363.

Why should you go solar?

How much can I save?
The average SolarKraft customer saves up to $1,500 per year on their electricity usage. This will vary from household-to-household, depending on factors such as system size, energy usage amount, usage times, your feed-in-tariff, and more.
What is net metering?

Net metering is a way of measuring your energy usage. It calculates how much energy you export to the grid, and how much you draw from the grid. This means that you get a credit for what you’ve exported, and only pay for the grid energy you use once your solar system isn’t producing enough for your needs (either at night or during peak-demand times).

Does it improve property value?

If you’re considering selling your house, you might be thinking of renovating an old bathroom or even the kitchen to boost your home’s selling price. But did you know that solar rooftop panels could have a similar impact on your asking price? According to realestate.com.au, 85% of Aussies say that solar panels add value to a property. The research also found that three out of four renters fancy green living and would be willing to pay extra for a rental if the sun powers it.

If you’re someone who thinks that solar panels are ugly, here’s the secret weapon: black panels. That’s right – you can get sleek black panels to line your roof, giving your home a modern look and feel.

Does it reduce my environmental impact?
Your environmental impact is reduced more if you have a larger system installed. A single household with a 5kW installation will prevent over 6,000 kg of carbon emissions in its life. SolarKraft alone has eliminated several million tons of carbon emissions in the last twelve months!
How safe is it?
Solar installations are extremely safe. There are no emissions, toxic elements, or live wires. What’s more, using an installer credited by the Clean Energy Council ensures that the quality of your installation is held to very high standards. As we only use CEC-approved installers, all of our installation work is guaranteed for ten years, on top of the 10-year product warranty and 25-year performance warranty we provide.

How does a solar panel system work?

How do panels work?

Household Solar Diagram


  1. Solar panels turn sunlight into DC (direct current) electricity
  2. The solar inverter converts DC electricity into AC electricity, which is first used to run your appliances, and any excess power is exported to the mains grid
  3. Electricity meter distributes power throughout the home. At night when sunlight is not available, the inverter switches itself off and your house runs on regular mains AC electricity
  4. Your electricity retailer tracks the difference between power used and power generated
  5. Your connection to the grid ensures continuous access to power
Do they stop working on a cloudy day?

Absolutely not! Your output will reduce by a varying amount, depending on what type of panels and inverter you have, whether your system has optimisers, and even the orientation of the panels – but it won’t stop completely.

Will I still get a bill?

This depends on the size of your system. Most 5kW systems will greatly reduce your bill, but won’t eliminate the costs of an average household’s usage.

Why does system quality matter?

You probably have a fair idea now of the importance you should be placed on system quality. You want more than just “good” – you want proven brands with solid track records. Systems backed by decent product and performance warranties will prevent long-term costs that come from a poor quality system. That’s why we only use the best brands in the world, for all of our inverters, panels, and batteries. Your peace of mind is priceless to us.

Does solar work in a blackout?

This depends on your system setup. For most installations, your system will shut off alongside the grid in the event of a blackout. This is primarily because if your system continued producing and exporting power while the grid was off, it would cause safety hazards for electricians who work on the affected power lines, as there would still be live electricity in the area.


However, if you have blackout protection, such as our Redback hybrid system, you will still have access to power. This also applies if you have a battery installed.

What if there's a problem?

Your first step in troubleshooting is resetting your inverter. If this hasn’t worked, you can send a maintenance request to us, or call us on 1300 985 363, and we will happily assist you.

How much energy should my system produce?

A standard 1 kilowatt PV system will not produce 1kW of power continuously. Because of inefficiencies caused by a number of factors, you will usually produce about 80% of the panel power rating at peak sunlight. For Queensland, a 1kW grid-connect system can be expected to produce on average about 4.4 kWh per day.

City 1 kW System 2 kW System 3 kW System 4 kW System
Adelaide 4.2 kWh 8.4 kWh 12.6 kWh 16.8 kWh
Brisbane 4.2 kWh 8.4 kWh 12.6 kWh 16.8 kWh
Cairns 4.2 kWh 8.4 kWh 12.6 kWh 16.8 kWh
Darwin 4.4 kWh 8.8 kWh 13.2 kWh 17.6 kWh
Melbourne 3.6 kWh 7.2 kWh 10.8 kWh 14.4 kWh
Sydney 3.9 kWh 7.8 kWh 11.7 kWh 15.6 kWh

Should I get solar?

How much does it cost?

Prices vary depending on system size, panel brand, inverter brand, and roof size. All of our prices are consistent with the Clean Energy Council guides, who also ensure quality installers and provide additional warranties.

I can't afford to pay upfront, what are my options?

We’ve got plenty of financing options available, including a $0 upfront option with weekly payments starting from $27. Find out more here!

Should I pay using cash or financing?

If you ask your financial planner, he may not necessarily say ‘cash’. If you want the best financial outcome, why not look at putting it towards your home loan? Knocking off a big chunk now can save you a LOT in the future.

Or, if you work to live and money is a vehicle to create experiences, why not take your loved ones on a well-earned holiday? In ten years, you’ll probably remember the trip to Fiji with fonder memories than the day you installed solar. And we love solar.

The final decision rests with you, but don’t instantly think that cash is your best bet. If you can secure a payment plan that doesn’t charge interest or hit you with outrageous fees, you may find that your cash is best left in your hands.

How do I know if my roof is suitable for solar?

The ideal roof has little shade and lots of space. However, even if your roof isn’t the ideal setup, we’ve got plenty of options to adapt to your needs. Our expert installers have a range of workarounds for small spaces, shading, and awkward roof orientations.

How long will the system last?

In a good quality system, panels have a guaranteed minimum 25-year performance warranty – for most brands, this is roughly 82-88% of the original performance. For inverters, a top-brand model should last 10 to 15 years, with most brands offering a standard 5-year warranty. We recommend installing an inverter with a 10-year warranty, or extending the offered warranty to this time frame.

How do I choose the optimal system size?

Determining the size of the solar system you need depends on several variables and personal preferences. For example, do you want to go off-grid, hybrid or do you just want to reduce your energy bill as much as possible? There may be factors beyond your control, eg. lack of roof area or shading issues. All of these factors and more need to be considered when you’re trying to estimate the optimal system size for your home. Simply trying to find the biggest system at the cheapest price is a recipe for disaster.


You also need to consider factors such as budget, sunshine hours, power usage times, and more. We’ve got a breakdown of all of these factors here.


What should I know about buying a system?

What size do I need?

The size of your installation will depend on your energy needs and goals. Some people are aiming to offset their bills, whilst others want to eliminate them entirely. Your energy needs will also vary based on factors such as number of household occupants, pools, air-conditioning, and more. The best thing you can do is decide on your energy goals, so you can be sure that you’re installing the system that you want and need.

What rebates are available?

All quotes that you see from any company have already factored the rebates into them. Rebates are issued through creation of STC’s – Small Technology Certificates. These are issues for every megawatt of electricity the solar panel system will produce over a period of one year, five years, or a lifetime. It’s usually recommended that you sell all of these, as they can be traded for cash reductions on your system.

How can I squeeze the most out of my system?

Making the most of your system involves a combination of factors, such as keeping your panels clean, ensuring you have a good tariff, and your system is consistently maintained. You can see more hints here.

Should I install a battery?

Whether you decide to install a battery will depend on how high your energy needs are. The cost of a battery can vary from anywhere up to $14,000. To find out if a battery is beneficial for your system, we recommend talking to one of our consultants about your energy goals.

How much is the feed-in tariff?

Your feed-in tariff will depend on who your energy retailer is. Depending on the plan you sign up for, your tariff could be anywhere from 6-16c per kWh. You don’t have to stay with your current energy retailer – you can switch once you install solar to get a better deal.
