6.6kw Solar System: Panels, Pricing, Power Output

To accommodate a 6.6kW solar power system, you`ll need approximately 31.7 square meters of suitable rooftop space. This estimation is based on panels measuring approximately 1.8 meters x 1.1 meter each.

The 6.6kW solar system is an ideal choice for single-phase homes with a maximum 5kW inverter capacity and households that consume an average of 20kWh of electricity per day. There are two primary reasons for its popularity:

1. DNSP Inverter Limitations: Most Australian homes use single-phase power, and Distributed Network Service Providers (DNSP) typically do not allow single-phase homes to install inverters exceeding 5kW capacity. Therefore, a 6.6kW system is the largest viable option for such homes.
2. Power Output: Depending on your location in Australia, a 6.6kW solar system can produce between 20kWh to 27kWh of electricity daily, which aligns with the electricity consumption of the average Australian household.

On average, a 6.6kW solar system in Australia generates around 24 kilowatt-hours (kWh) of electricity per day, which is more than the daily consumption of the average Australian household. The actual output may vary based on installation location, panel orientation, and component quality. Additionally, feed-in tariff payments can further contribute to your energy savings.

As of mid-2023, the cost of a 6.6kW solar system with quality components and professional installation typically ranges from $5,200 to $8,700. The final price can be influenced by factors such as the quality of products used, solar installer charges, and solar incentives and rebate claims.

A 6.6kW solar system can lead to annual savings ranging from $950 to $2,000, with the potential for lifetime savings exceeding $50,000. These savings are realized through reduced energy bills and feed-in tariff credits. Several variables, including energy consumption, electricity rates, and feed-in tariffs, influence the amount of savings you can achieve.

Typically, a 6.6kW solar system has a payback period of approximately 3 to 5 years, assuming a reasonable installation cost, solar incentives, and a significant level of solar energy self-consumption. Several factors can influence the payback time, including installation cost, energy consumption, and location.

The daily power production of a 6.6kW solar system varies based on location, solar panel orientation, and shading. In Australia, these systems typically produce between 20kWh to 27kWh of electricity per day. Sunny locations like Darwin yield higher production compared to temperate regions like Hobart.

A well-maintained 6.6kW solar system can last for over three decades. The key components and their lifespans are as follows:

1. Solar Panel Array: Solar panels have a productive life of 25 to 30 years, with some manufacturers offering 25-year performance warranties. While panels degrade over time, they can still perform at 80% of their original efficiency by year 25.
2. Solar Inverter: Solar inverters have a lifespan of 10 to 15 years, necessitating replacement during the system`s lifetime.

Before installing a 6.6kW solar system, there are several considerations to keep in mind. These include assessing your roof`s suitability, ensuring adequate sunlight, calculating installation and maintenance costs, and evaluating the long-term benefits. It`s also valuable to seek input from friends and family who may have experience with solar systems.

If your area experiences frequent power outages, adding batteries to your 6.6kW solar system is advisable. However, in areas with infrequent outages, understanding off-peak and peak power pricing with your retailer is essential to maximize the use of your battery. Our experts recommend a minimum battery size of 5kW for sufficient storage capacity.

Absolutely! A 6.6kW solar system produces ample electricity to power most Australian homes. On average, Australian households consume around 20kWh of electricity per day, and a 6.6kW system typically generates between 20kWh to 27kWh daily.
