How Much Does Solar Panel Installation Cost
The cost of installing a solar panel system is built into the price for most solar companies.
If a company is advertising the price for a 6.6kWh solar panel system as being $5,899, this price includes installation after the rebate.
Any solar installer claiming they will charge you extra to install the system is most likely a scammer.
Payments From The Feed
The Feed-in-Tariff was a Government-backed scheme where you get paid for the energy your solar panels produce. Your energy supplier makes the payments to you every three months.
The scheme was designed to reward householders and businesses for investing in renewable energy.
The Feed-In-Tariff will be replaced with the Smart Export Guarentee.
How much do you get?
FIT payments have two parts:
- This part of the payment is for the energy you produce, even when you use it yourself.
- Youre paid a set rate for each unit of electricity you generate.
- Once your solar panel system is registered with the FIT, the rates youre offered are guaranteed for the full period of the scheme but will rise or fall with inflation.
- Currently you get:
- 3.93p per kWh if your solar PV system is below 10kW
- 4.17p per kWh for systems between 1050kW
Kw Solar System Financial Returns
The financial returns from a 4kW solar PV installation are mainly dependent on the presence or absence of a solar feed-in tariff to the owner/operator of the system. Solar feed-in tariff schemes pay solar system owners a premium for each kWh of power that they send to the electricity grid. Financial payback accordingly depends not only on the total output of the system, but also how that power is utilised by the occupants in light of whether or not a Solar Feed-in Tariff is being applied.
There are essentially 3 situations that owners of grid-connect solar systems might find themselves in regarding Solar Feed-in Tariff incentives:
1. They have access to a Solar Feed-in Tariff, which encourage solar system users to export power to the grid at rates that vary from state to state, but which are above the retail electricity ratethat is, a premium.
2. They have access to a 1-for-1 Solar Buyback scheme in which they are paid an amount equivalent to their retail electricity rate for every unit of solar power that they feed into the grid. People in this category should simply try to reduce their power consumption as much as possible, as they can neither gain nor lose by either exporting or self-consuming their solar p0wer.

How Many Solar Panels Do I Need Then
Related:How many solar panels do I need?
Typically, a modern solar panel produces between 250 to 270 watts of peak power in controlled conditions. This is called the nameplate rating, and solar panel wattage varies based on the size and efficiency of your panel. There are plenty of solar calculators, and the brand of solar system you choose probably offers one. That said, there is a simple equation to calculate the amount of kilowatt-hours your solar panel system will produce.
So now that we know you need to produce about 6kW of AC output, we can work backwards to figure out how many solar panels you need. Solar panels produce direct current , and your home runs on alternating current .
Yep, like the band, AC/DC.
Because of physics, there are losses in converting the energy from the sun into DC power, and turning the DC power into AC power. This ratio of AC to DC is called the derate factor, and is typically about .8. This means you convert about 80% of the DC power into AC power.
This continues to improve ever so slightly, but the losses are unavoidable because of physics! So you take the AC amount you need: 6kW and divide by .8 . This means that youll need 30 250Wp solar panels or 27-28 270Wp panels.
Is This Solar Panel Kit Right For Me
A 4kW Solar Kit requires up to 230 square feet of space. Ideal output will be achieved with an unobstructed south-facing view of the sun for maximum solar power. 4kW or 4 kilowatts is 4,000 watts of DC direct current power. This could produce an estimated 300 to 750 kilowatt hours of alternating current power per month, assuming at least 5 sun hours per day with the solar array facing South. The actual power generated will vary based on location, equipment and installation factors. Refer to your electric utility bill to find the actual kWh used per month and compare it to how much power these low cost 4kW PV systems can generate.
The kWh generated monthly by these systems is great for eliminating the impact of a hot tub or running the air conditioner. A 4000W Complete Solar Kit could offset 1/3rd of medium user’s consumption which may equal 1/2 their $ part of the bill.

Best Solar Panel Manufacturers
The price of a solar PV system will depend on its size and quality. The best solar panels are the ones that produce the highest percentage of usable electricity, in other words they have the highest conversion percentage rate.
As with most things, you get what you pay for. So ideally choose a brand which has a good reputation and is known for reliability and quality of build.
The best solar panels will depend on your requirements, not least the size of your roof and which way it is facing. Houses with smaller roofs need panels that produce the most power per square foot. If thats the case, monocrystalline solar panels, although a bit more expensive than monocrystalline panels, would be the best option.
When it comes to choosing a manufacturer, stick to the popular brands. Well known solar panel manufacturers include:

Editors Note: This Is An Overview On How To Understand How Much Energy Your Solar System Will Produce And Overall Solar Panel Output
We always advise speaking with at least a few certified solar installers to understand how all the factors will affect solar panel output for your system.
Solar panels indicate how much power they intend to produce under ideal conditions, otherwise known as the maximum power rating.
But how much electricity your solar panels produce depends on several factors.
- Does intermittent shading obscure direct sunlight from hitting the roof?
- How much sunlight does your roof get on average?
- How big are the solar panels, and how efficient are the solar cells at converting energy?
Because the seasons and weather conditions affect the amount of sunlight hitting your roof, and the amount of sunlight also varies on the time day, you cant use just the solar panel ratings to predict how much power youll get. However, your location will allow you to do some math and determine how well a solar panel works where you are.

Case Study Battery Size For 5kw Solar System
In the case of Battery Size for 5kw Solar Systems, it all comes down to where youre located in Australia, the positioning of your solar panels and how much energy you both produce and need to produce for back up.
If you already have a 5kW system or are considering purchasing one, youll need to consider the correct battery size for a 5kW system. Look at a 5kw solar panel system specifically, you will likely need a battery with a capacity of at least 10kWh, more likely, up to 13.5kWh.
Generally speaking, a 5Kw solar panel system will produce anywhere between 1721 kWh per day, depending on where youre located in Australia. For most properties, approximately two-thirds of a systems energy production is fed back into the grid which is around 13 KW a day. Instead of being fed back into the grid, this 13kW could be collected and stored solar power in your battery.
However, if your property uses closes to half of your power during daylight hours, this means that half of the energy produced will be sent back to the grid. Consequently, you could use a smaller size solar battery like a 10kWh.
The exact battery size needed will come down to how much electricity you typically consume during daylight hours and what you wish to achieve with a solar battery. In our experience, the Tesla Powerwall battery provides an exceptional solution for a 5kw solar panel system.
