13.2kw solar system has high-quality solar PV cells with better sunlight capturing capabilities, a faster energy conversion rate, and an extended service life.

Compared to the 10KW solar power system and, this system shows that the 13.2 kW or 13kW solar installation cost is a bit higher than 10KW but its production capacity is more than the cost.

So, that is why we are seeing an increase in demand in installing this larger 7.7kW, 10.5kW, and 13.2kW systems all of a sudden?

The most important reason, in our opinion, is that more people are going solar with the intention of future-proofing a future battery installation, and with the exorbitant power prices we are currently paying, people are realizing that having more panels will simply serve them better in the years ahead. Many people are waiting for battery costs to decrease further before investing in a home battery, as they are now too pricey, even with the government rebate.

Specifications and Cost of a 13.2kw Solar System

It’s very difficult to say how much solar panels cost to install per watt, Coz it depends on various issues, like the type of solar panel and brand, Inverter type, house’s power design- single-phase or three-phase Roof design etc. Even the price will decrease if you buy a larger solar system.In NSW, the average cost of a 13kw or 13.2kw solar panel ranges from $5800 to $7000, including taxes and rebates according to the solarworld power.com.au offer chart without battery (as of Jan 2022). The cost will vary based on the size of the inverter, the capacity of the solar cells, the size of the battery, and other factors.

With a 13kW solar system, a 10kW solar inverter is recommended. If you want to have an off-grid solar panel system, you’ll need a higher battery size, which can range from 10kWh to 50kWh. A greater battery size allows the consumer longer days of energy independence. Specifications indeed determine the price of a solar power system, but this does not imply that a low-cost solar system is worse. In the end, one factor determines the specs for your solar power system: the size of your property or accessible

Average solar panel output per day Australia summer vs winter

The productivity of any solar panel depends on the sunlight, heat, and environment of the area concerned. We all know that NSW isn’t all sunny and that our winters can be dark, chilly, and wet! So we know that throughout the summer, your solar system will generate enough electricity to power your home, air conditioning, and also charge your battery during daylight hours. In fact, the following are the typical daily summer output rates:

Average Winter Energy Production

 Now we come to the design limits, which is why we try to install as many panels as we can on your roof, while staying under budget and with the possibility of adding batteries later. What about winter, which accounts for a quarter of the year’s performance?! Let’s have a look at your daily average energy production rates during the cooler months now:

 As you can see, a 6.615kW system would be disappointing in the winter, only producing enough electricity from your solar panels 50% of the time to completely charge it and having to rely on the pricey grid for electricity all day. In this case, an LG Chem might be more appropriate than another brand. Our current advise is to install now and take advantage of the existing Feed-In Tariffs before adding a battery once the starting prices have reduced. This mindset is influencing the appeal of larger 7.875kW, 10.71kW, and 13.23kW systems in Australia.

A 13.2kW Solar System generates how much energy?

The power generation of any solar panel depends on many factors.

The principal issues for optimal energy production are summarized below:

  • After examining your property and location, the installer will set up the panel’s orientation and tilt alignment.
  •   The abundance of sunlight and the intensity of heat depending on your local geographical and climatic conditions.
  •  Most of the solar panels are installed on the roof of the house. The amount of shadow falling on the panes ‍ depends on the object like a tree or a large building nearby.
  • Due to the cloudy weather, the production capacity of solar panels is greatly reduced due to the lack of sunlight.
  •  The performance, quality of solar PV cells, Depending on the quality of solar panels, solar inverters, solar charger controllers, solar batteries, and other components.

On a north-facing solar system in Sydney, a 6KW or 6.6 KW Solar Electricity System delivers 30-35 kWh power production.This means that if a 13.2kw solar power system in Sydney is used at a rate of more than 70% efficiency, it may create 60-70kWh.

How much space is necessary for a 13.2kw solar power system to be installed?

The size and number of solar panels utilized determine the amount of space required for a 13.2kw solar system to be installed. A total of 30-35 solar panels are required, with a solar panel measuring 211.5 × 105.6 × 4 cm on average weight 22.3kg( Basis on LG 450w panel).

This specification applies to a 370-450 watt panel. As a result, a roof space of roughly 70-82m sq. is required to install this system. The amount of space needed is also determined by the roof’s form and the design of the solar frame, which can be slanted or flat placed.



Because more solar panels are necessary for a 13.2kw solar system, it may be slightly larger for a small or typical property. A 5KW solar power system is a suitable choice for a small or medium-sized home. If you’re short on area, you can make do with the rooftop, roof walls, and align the angle of solar panels with the structural shape of the roof.


The 13.2kw solar power system is ideal for commercial and large residential applications with high energy usage. It may be used to power small enterprises and large families. But if you have a big house and the bill is higher than $500 then you can go for a 13kw solar system also. A 13.2kw solar panel system is optimal for both energy consumption and savings if you have a suburban home, an industrial unit, commercial property, or a warehouse. Solar power systems are suitable for everyone and every property; all you need to consider are the parameters impacting power output, installation space, and your geographical climatic conditions.

A 13.2kw solar panel system will be productive and profitable if all circumstances are favorable at your location and you have the space available. It will also have a short payback period and provide efficient power output to meet personal needs as well as feedback into the electric grid for energy transmission.

Some air conditioners require as much as 2.5 kw, so that your solar panel system’s minimum capacity would have to be 3 kw only to power the air conditioning. The air conditioner would devour this in less than four or five hours. They are high-demand items that consume a lot of energy to maintain their functionality.

All that’s needed for a typical modern home to function entirely on solar power is a mechanism to store the energy when the sun isn’t shining. That is doable, especially now that the Powerwall is available, but they are still very expensive and can only store 5-10 hours of power, depending on your home’s energy consumption.

Silicon is the main element of a solar panel. If you maintain and properly clean solar panels, they can last for at least 25 years. However, they lose productivity over time. Most of the panels come with a 20- 25 year output warranty. Low-cost solar panels use materials with lower long-term durability, and some have begun to fail in Australia’s severe climate.

How many solar panels does it take to power a typical home? According to the last survey of 2018, the average residence is about 2,631 square feet, with monthly electricity bills of around $300. To totally meet the electrical power needs of such a house, around 6.6 kW panels are required.

You can figure out how many solar panels you’ll need. To calculate your household’s energy demand, you divide your area’s peak sunlight hours by the wattage of each panel. To create a range, use a low-wattage (150W) and a high-wattage (370W) example (ex: 17-42 panels to generate 11,000 kWh/year).

How many solar panels does it take to power a typical home? According to Garrison, the average residence is about 207 square meters,  according to the Australian Bureau of Statistics with monthly electricity bills of around $300. To totally meet the electrical power needs of such a house, around 6.6 kW panels are required.
