Is A 66kw System More Expensive Than A 6kw System
Yes, but not much more. Expect to pay around $200 more for a 6.6kW solar installation. Youre probably buying two extra 300-watt solar panels to make a 6.6kW system. Its not a big difference in price. But the difference in output efficiency is worth the extra investment.
The difference in the system cost is negligible because the extra work your solar installer needs to do in the installation process is minimal. They are already on site, and the solar inverter is the same as used in a 6kW system. So the extra system size only involves installing a couple more solar panels and some extra cabling.
How Much Money Can I Save With A 12 Kw Solar System
$24,612 is quite a lot of money, so the next logical step is wondering how much can you save with a 12 kW system. If you save more than you spend, it makes financial sense to install! So how much money can you save with a 12kW system? Lets do the math!
To calculate your savings, we need to compare your total solar installation cost of $24,612 to your total cost if you continued to purchase all your electricity from the utility for the next 25 years .

If youre considering solar panels for your home, youll get the most value from them by directly self-consuming the energy that they produce during the daylight hours. The simple reason for this is that using the solar yourself allows you to avoid purchasing expensive energy from the grid instead of earning only a small credit for sending it into the grid. This is a crucial fact about going solar in Australia today.
How Much Space Do We Need On The Roof
A 6kW solar power system comprises 24 solar panels and requires roughly 43 square meters of roof space. Should you have any concerns about whether you have sufficient room on your roof to fit this many panels, rest assured we can help. Get in touch with one of our team members to discuss your options as we have a number of solutions when space is limited.

How Expensive Is A 6kw Solar System
At the national average cost of $2.93 per watt, a 6kW solar system would cost you around $17,580. With the 30% federal tax credit applied, that total drops to $12,306.
Thats a lot of money, so the real question is whether $12,306 for a 6kW installation is a good deal? Well, lets do some math and find out!
Going back to our example above, a 6kW installation in San Antonio produces 8,370 kWh in a single year. The solar industry estimates modern solar panels to last about 25 years, in which case the San Antonio installation would produce 207,253 kWh by the end of its life. Solar panels also lose about 0.08% efficiency each year due to their internal parts degrading, so weve added that loss into our estimate above.
In Texas, the average utility charges $0.1156 per kWh. Utilities typically raise their rates about 2.5% each year, so purchasing 207,253 kWh over 25 years would cost $37,274. Subtracting your initial investment from the total price you wouldve paid the utility if you never went solar, we find that a San Antonio homeowner can save $24,968 by installing a 6kW solar installation!
Texas utility rates are actually lower than the national average, so if youre thinking about installing solar, chances are high youll save as much or more than $24,968 over the life of your installation, though of course it depends on your utility prices, weather, and financing.

Why Oversizing Your Solar Energy System Is A Good Idea
Oversizing is when your solar panels have a greater output capacity than the inverter used in the system. We explained before that a 5kW inverter can handle 133% of its maximum capacity in solar panels .
Its perfectly safe to do. Most solar arrays dont continually produce their peak output. This is because of factors such as sub-optimal tilt angle, weather, dirt, poor efficiency, system losses, and temperature. On a typical hot day a solar panel will lose about 10% of its peak power output capacity. If you have 20+ solar panels in your solar array, thats quite a drop in efficiency.
And remember, some Australian DNSPs dont allow inverters larger than 5kW to be connected to the power grid. So you want to maximise its capacity and performance.
Kw Solar System And A 5kw Inverter
A 5kW solar inverter is generally included in the price of a 6kW solar system.
Solar panels are a great way to reduce your electricity bills and help the environment. In Australia, Small Scale Technology Certificates can be used as an incentive for installing solar systems in homes or businesses that meet certain criteria regarding the size of installation locations within residential areas off-grid locations lasting up until 2032 when they will no longer exist at all!
Solar energy has become one of the most unusual ways Australians use renewable resources, but theres always room for innovation!
Under the STC program, the inverter installed at the premises may be overbuilt with panels by 33%. This 33 percent threshold also applies to the people who install your poles and wires.
For you as a customer of electricity, it is important that not just anybody can come into our homes uninvited! The installation process requires special permission from building owners or managers before entering with tools such as saws and drills, which could potentially damage property while working on their behalf however, there may be some exceptions depending on what type of work needs to be done .
Installing a 6kW Solar System will allow you to use the most STCs on your 5kW inverter, and it ensures that your distributor is satisfied whether power comes from single or three-phase sources!

Can Your Roof Support A Solar Panel System
Armed with the knowledge of solar panel size and solar panel weight, we can make a calculation about how much a whole solar panel system weighs which in turn can help you understand whether your roof can support a new solar panel system or not.
In a 6 kilowatt solar installation made up of 20 solar panels, the panels alone will weigh approximately 800 pounds . Based on our calculation above, we know that this same system measures at 352 square feet, which works out to a weight of 2.3 pounds per square foot . When you include the mounting hardware and other equipment for your panels, the total weight will be closer to 3-4 pounds per square foot.
The roofs on most newer homes can handle significantly more than 3 pounds per square foot of weight. However, if you have an older roof or are in any way concerned about whether your roof can support the additional weight of solar panels, talk to a roofing company. A straightforward roof inspection can help you determine whether the additional weight of solar panels are a viable option for your home.
How Long Is The Payback Period On A 66kw Solar System
The benchmark by which most solar shoppers measure their panels performance is the payback period the number of years that the system will take to pay for itself in energy bill savings & feed-in tariff credits.
The table below shows indicative payback periods, internal rate of return and annual savings in the first year for 6.6kW solar systems in a handful of Australian capital cities based on average prices as of March 2022.
Keep in mind that returns may be better for systems whose price points are lower, or if you achieve a higher level of solar self-consumption. But also be mindful that youll want to be selective about the products and companies that you consider some deals are too good to be true.

Range Of System Sizes
Solar power systems are available in a range of sizes, but the smallest system a solar panel installation company will offers is 1.5kW. Solar power systems for households rarely go above 10kW in size.
A 6kW solar panel system produces enough electricity to match the average New Zealand household’s consumption of grid produced electricity . However, matching a system size to your power demands won’t eliminate your power bill. When exporting a percentage of power to the grid, power companies don’t pay as much for your exported power as what they charge for power. See buy-back rates here>
If the aim is to eliminate your electricity bill, then you will need to increase your solar power self-consumption, and/or include battery storage.A 3kW grid connected solar power system has proved to be a popular system size in New Zealand, due to the fact that it will make a significant change to your power bill and is relatively affordable .
A 3kW system in Auckland generates approximately 3740kWh/year. For the average New Zealand home, eliminating your power bill with a 3kW system is unlikely. However, a slightly smaller system will ensure that a large portion of the power from the system is used by your household with less power being exported to the grid, maximising your return on investment.

Should You Buy A Solar Battery
If you want your solar PV system to pretty much cover all of your energy needs, youll also require a solar battery.
If you dont use solar-generated electricity immediately after it is created, then it will go back into the grid. Homeowners with solar panels need to be in their house during the daytime in order to use their solar energy, or else it will go to waste.
However, with a solar battery, you can store up all the solar energy that doesnt get used. Then, once youre back home in the evenings and the sun has gone down, you can still power all your appliances with solar energy. Whats more, electricity from the grid is even more expensive in the evenings when demand is higher, so youre dodging the priciest time for grid power.
You can find out more in our complete guide to solar batteries, which includes information about typical costs, pros and cons, and the best models on the market. Naturally, its the biggest batteries that are most capable of taking you entirely off-grid, such as the Tesla Powerwall 2.0 or the Sonnen Batterie eco .
What Is The Rebate On A 6kw System
The average rebate on a 6kW solar system is $2,849. This is for states NSW, QLD, SA, WA ACT and NT. The remaining states of VIC and TAS have a rebate of $2,387. Rebate amounts are determined by the number of STCs that are available for you in your state on a 6kW system, multiplied by the current trading price of STCs.

Who Can Benefit From 5kw Solar Panels
For homes and very small businesses, such as a sole trader, a 5kW system may be a smart choice. With 5kW solar panels, youll have enough power to cover most of your home or businesss energy usage, making this a perfect starter system for most residential applications. Its also a good entry point for any commercial space that doesnt require heavy energy usages such as a one or two-person office or small shop.
When you start with 5kW solar panels, you can still upgrade to a larger system in the future if your needs change.
What Can I Run On A 6kw Solar Panel System
What can I run on a 6kW solar system? That is the question that many people are asking, and its not an easy answer. Do you have a 6kW solar system? If youre not sure, heres what that means: A 6 kW solar system generates about 3.4 kWh of power per year.
This is enough energy to power the average home in Australia for a little over a month according to Ben from Go Solar Quotes! That sounds like a lot, but if your household consumes an average of 1 kWh per day, it will take just under two years to go through this much energy. Many factors go into deciding what you can power with your solar panels, including how much direct sunlight you get in your area. If youre looking to install a new solar system for your home or business, consider using tools like Google Maps to see if there is enough sun exposure nearby. Solar panel capacity also plays a role in determining what type of items you can use at one time. So if you have a 6kW solar panel system but need more than 6 kW worth of electricity at one time, then this means that some appliances will be cut off until demand drops again.
