6.66kW Vs 9.99kW Vs 13.32kW -The Best Solar System Size Perfect For Your Home

Switching to solar can be a perplexing decision as you have to skim through several solar product specifications, their sizes, and compare the suitable solar power system for your home. Here at Space Solar, we have pre-configured solar packages for residential and commercial properties that are available in multiple sizes with installation included.

In our today’s blog, we will compare and understand the specification of the three best sizes of solar system viz. 6.66kW, 9.99kW, and 13.32kW for your home. We will also cover a variety of other questions related to these solar system sizes, so stick around!

6.66kw Solar System

6.66kW solar systems are best for medium to large households using a substantial amount of electricity. The 6.66kW solar system is one of the best performing solar systems for home available in the market and can help you save approx $350 per electricity bill. However, your actual savings may be anywhere between $180 and $300 per electricity bill cycle.

This itself will be more than enough to cover your home’s entire energy usage! 6.66kW is a perfect starter solar system for most residential properties. 

6.66kW solar systems are also beneficial for businesses with small commercial space.

This solar system’s size is great for any commercial space that doesn’t require excessive energy usages such as a one or two-person office or small retail shops. Young families and small businesses can start with 6.66kW solar panels and then upgrade to a larger system size if individuals need to increase or for a change.

How Much Power Does A 6.66kW Solar System Produce?

Generally, a premium quality 6.66kW solar system will generate 24KWH per day, which is enough to cover a typical Australian household’s complete energy usage and needs.

The amount of power produced by your 6.66kW solar system will depend on three important things: your location, placement of the solar system, and quality.

A location with a good amount of sunlight is the ideal place for installation. If you reside near a cloudy location, make sure to buy a premium quality solar system as it will help you reap the benefits of this free and inexhaustible source of energy.

Additionally, you should also invest in various solar technologies such as power optimisers to get the best out of your solar panel system.

We recommend you buy robust and top tier quality solar panels and inverters for best results. Our expert solar installers will also share with you their expertise regarding the correct solar installation, which will help you generate the maximum amount of energy possible all 365 days a year!

How Many Solar Panels Do I Need For 9.99 KW?

For a standard 370-watt panel, a 9.99 kW solar system will have 27 solar PV panels. Similarly, for 390-watt panels, it will be 26 solar panels. Since each panel will be around 1.75m by 1.05m in size, you’ll need a minimum of 34m2 of roof space for installation.

9.99 KW Solar System

9.99kW solar systems are great for large families or small businesses and provide the perfect balance of great power capability at an affordable rate. If you have above-average energy consumption levels, 9.99kW solar systems are perfect for you! With 6.66kW solar systems, you can either sell the excess energy produced to the grid through Feed-In Tariffs (FIT) or store it in solar batteries for later use.

9.99kW solar systems will also allow you to obtain more Small-scale Technology Certificates (STCs) as these certificates are based on the capacity of the solar PV panel rather than the inverter’s size. People are finding 9.99kW solar panels as their ideal solar system because of their sharp decline in cost. Additionally, government solar rebates are also declining in value. 

How Much Power Does A 9.99 KW Solar System Produce?

Large Australian homes use up to 40-kilowatt hours of electricity per day. A 9.99kW solar system is more than enough to produce such an amount of electricity and fulfil the energy needs. However, several factors may influence the total power production from a 9.99kW solar system including sunlight hours, shade, outside temperature, and PV panel orientation.

On average, Australia receives approx 5 hours of peak sunlight every day, which means that a  north-facing 9.99kW solar panel system will generate an average of 32kWh to 40kWh of power every day!

For a standard 370-watt panel, a 9.99 kW solar system will have 27 solar PV panels. Similarly, for 390-watt panels, it will be 26 solar panels. Since each panel will be around 1.75m by 1.05m in size, you’ll need a minimum of 34m2 of roof space for installation.

13.32 KW Solar System

For large residential and smaller commercial properties, a 13.32 kW solar system is a great fit for your energy needs. A 13.32kW solar system will cover the average Australian household’s energy usage of about 19,418 kWh of electricity per year. 13.32kW solar systems can produce enough energy that will help you go off-grid. The excess energy produced by a 10kW off-grid solar system can be stored in solar battery storage for future use.

How Much Power Does A 10 KW Solar System Produce?

A 13.32kW solar system can produce anywhere between 11,000 kilowatt-hours (kWh) to 15,000 kWh of electricity per year. However, the figures may vary depending on your location. For instance, Australian cities experienced an ample amount of sunlight. Solar panels in sunnier states will produce more electricity than solar panels in states with low sunlight.

How Many Solar Panels Do I Need For 13.32 KW?

For a standard 370-watt panel, a 13.32kW solar system will need 36 solar PV panels. Similarly, for 390-watt panels, it will be 34 solar panels. A 13.32kW solar system will need a minimum of 475 and 615 square feet of roof space for installation.
