Do you dream of an energy self-sufficient home that produces the least possible electric bills? Do you want to be a proud contributor to sustainable energy for a greener future? Installing a rooftop solar system with an inverter and a battery can be a wise decision.
Are you confused about choosing between the most popular options: a 6.6 kilowatt solar system and a 10-kW solar system? Let’s find out what you need to consider in this brief guide.
Striking a Balance Between Your Needs & Available Options
Here are some technicalities to assess, to ensure a cost-effective solution to fulfil your needs by making the most efficient use of available resources:
1. Household Requirement of Electricity
As you install a 6.6kW solar system, you can expect a daily power output of about 24-27 kWh. It is sufficient for a small family with 2 to 4 members. It can cover your home appliances, illumination, and regular electric usage.
What if your energy demands are higher? A 10 kW solar panel system generates 38-44kWh per day. If you are a medium to large-sized family with a similarly large home, your energy requirement may be proportionately higher. In such a case, installing a 10 kW solar panel system could be a better choice.
2. Roof Size
How much area do your solar panels cover? Availability of roofspace for solar panel installation is a key factor to consider when exploring solar panel systems.
How much area do solar panels need?
- A 6.6 kW solar panel system typically comes with 15 panels of 440W power capacity each. So, this system occupies a roof space of about 30-32 square meters.
- A 10 kW solar panel system comes with 23 panels of 440W power capacity each. It requires around 45 to 50 square metres of your roof space.
3. Electricity Bills & Usage Patterns
Analyse the electricity bills for the past 12 months and try to figure out the following aspects:
Have you been paying a small to moderate electricity bill for the last year? You can offset it by adopting a 6.6 kW solar system.
Does your family consume much electricity during the day? Do you regularly use appliances, gadgets, illumination, and other items more than an average Aussie family? In this case, a 10 kW system would be feasible for saving on electric bills.
4. Budget & ROI
Technically, a 6.6 kW solar panel system is more cost-effective and has a typically low return on investment period. However, if your household energy requirement is higher, it’s advisable to go for a 10 KW solar panel system.
5. Suitability of Solar Panel System Type
Consider your goal for switching to rooftop solar. You can choose between on-grid, off-grid, or hybrid systems. If you have ample roofspace, you can go for a rooftop solar system and transmit excess power directly to the grid.
You can discuss options for additional batteries along with an inverter for storage. This surplus power can keep you covered during power outages or blackouts.
Choosing the Right Fit
Choosing the ideal option to harness Australian sunshine and reduce your energy bills can be tricky. Try striking a balance between your family’s energy needs, available roofspace, upfront cost of installation, and return on investment.
Ensure you pick the perfect option that could be best for your family, best for the environment, best bang for your buck, and all in all the best long-term investment.

FAQs
Q 1: What is a rooftop solar panel system?
Ans: A rooftop solar panel system generates electricity for your domestic or commercial consumption. The technology responsible for converting sunlight directly into electricity is the photovoltaic effect.
Q 2: What are the components of a rooftop solar panel system?
Ans: Usually, a rooftop solar panel system comprises solar panels, an inverter, a battery, an energy meter, and other electrical wiring components, depending upon its type.
Q 3: What are the benefits of installing a solar panel system?
Ans: 6.6kW or 10kW solar panel systems help you save much money on electric bills. If you sell excess power through an on-grid system, it could be a small source of passive income for your household.
