How Many Solar Panels Do You Need for a 6.6kW System?

Solar energy has gained immense popularity as a clean and sustainable power source for homes and businesses. One of the commonly sought-after solar systems is the 6.6kW system, known for its efficiency and ability to meet the electricity needs of many households. In this blog, we'll explore how many solar panels you need for a 6.6kW system, the roof area required, metering requirements in Australia, the system's output, and how Econnex can assist you in comparing solar panels from over 1000+ packages.

How Many Solar Panels for a 6.6kW System?

The number of solar panels required for a 6.6kW system depends on the wattage of the panels. Solar panels typically come in various wattage ratings, such as 300W, 320W, 350W, etc. To calculate the number of panels needed, divide the total system capacity (6.6kW) by the wattage of each panel.

For example, if you are using 350W panels, the calculation would be: Number of panels = 6.6 kW / 0.35 kW = 18.86 (rounded to 19 panels)

Remember, the actual number might vary slightly based on factors like panel efficiency, temperature, and shading.

Roof Area Required for 6.6kW Panels

The roof area required for a 6.6kW solar system depends on the dimensions of the panels used and their layout. Most residential solar panels are around 1.6m x 1m in size, but it's crucial to check the specifications of the specific panels you choose. With an average panel size, you'll need approximately 26-36 square meters of roof space for a 6.6kW system.

Roof Requirements for 6.6kW Panels

Before installing solar panels, ensure that your roof meets certain requirements:

• Orientation: The ideal orientation for solar panels in Australia is north-facing to capture the maximum sunlight. However, east and west-facing roofs can also work effectively.
• Tilt: Solar panels should be installed at an angle that maximizes sun exposure throughout the year. The tilt angle is often equivalent to your latitude, but slight adjustments can optimize performance.
• Shading: Make sure there are no significant obstructions like tall trees or buildings that cast shadows on your roof during peak sunlight hours.

Metering Requirements in Australia for a New Set of Panels

When you install a solar PV system, your metering configuration will change to accommodate the solar energy you generate. In Australia, there are mainly three types of metering:

• Gross Metering: All the electricity generated by the solar panels is exported to the grid, and you receive a feed-in tariff for it. You then buy electricity from the grid at standard rates.
• Net Metering: The electricity you generate is first used to power your home's appliances. Excess electricity is then exported to the grid, and you receive a feed-in tariff for it. If you require more electricity than your panels are generating, you purchase it from the grid at standard rates.
• Smart (Interval) Metering: Similar to net metering, but your electricity usage and generation are measured at 30-minute intervals. This type of metering is becoming more common in many regions.

Output from 6.6kW Panels

A 6.6kW solar system, on average, can generate around 24-28 kWh of electricity per day. However, the actual output will vary based on factors such as location, weather conditions, shading, panel efficiency, and the angle of installation.
