13.2kW Residential Solar System
What is a 13.2kW Solar System?
A 13.2kW solar system is a large-capacity solar energy solution suitable for homes with high energy needs or small to medium-sized businesses. This system can generate substantial electricity, making it ideal for properties with high consumption or those looking to export significant surplus energy back to the grid.
How many solar panels does a 13.2kW solar system have?
The number of solar panels depends on the wattage of each panel. Typically, solar panels range from 440W to 500W per panel. Based on this:
| Panel Capacity | Number of Panels |
|---|---|
| 440W | 30 panels |
| 475W | 28 panels |
| 500W | 26 panels |
How much electricity does a 13.2kW solar system produce?
The energy output depends on factors like location, roof orientation, and weather conditions. On average, a 13.2kW system generates:
- Daily Output: ~50 to 60 kWh per day
- Annual Output: ~18,000 to 21,600 kWh per year
This is sufficient to cover the electricity consumption of large households or small businesses.
What Are the NSW Rebates for the 13.2kW Solar System?
In New South Wales, solar rebates and incentives can significantly reduce the upfront cost of installing a 13.2kW solar system. The primary incentive comes from the Small-scale Renewable Energy Scheme (SRES), which provides financial benefits through Small-scale Technology Certificates (STCs).
For a 13.2kW solar system, you can typically receive between 165 to 190 STCs, depending on your location and system efficiency. Each STC can be sold or assigned to your installer to reduce your system’s total cost. As of 2024, the value of STCs is approximately AUD 35 to AUD 40 per certificate, potentially saving you around AUD 5,000 to AUD 6,000 on a 13.2kW system
In addition to the SRES, some local councils or energy providers may offer further rebates or low-interest loans to support the installation of solar power systems.
By leveraging these rebates, the cost of your 13.2kW system can be significantly reduced, making solar power a more affordable investment.
How Long Will it Take for the System to Pay for Itself?
A 13.2kW solar system typically pays for itself within 3 to 5 years, depending on several factors, such as energy consumption, electricity rates, and the available feed-in tariffs in your area. The faster your system generates savings from reduced electricity bills, the quicker you’ll see a return on your investment.
Here’s a breakdown of factors influencing the payback period:
- Energy consumption: Higher usage means greater savings.
- Feed-in tariffs (FiTs): Selling excess energy back to the grid accelerates payback.
- Installation cost: Lower upfront costs (after rebates) shorten the payback time.
- Location and sunlight: Areas with more sunshine generate more electricity, increasing savings.
With the right conditions, many households see significant savings early on, and a system can provide free electricity for decades after the payback period is over.
What is the Cost of a 13.2kW Solar System?
The cost of a 13.2kW solar system can vary depending on factors like the quality of solar panels and inverter, the complexity of installation, and available government rebates. Below is a table outlining typical price ranges for a 13.2kW system in Australia:
| System Tier | Estimated Price (AUD) |
|---|---|
| Budget | $4,600 |
| Standard | $4,900 |
| Premium | $5,300 |
Factors Affecting Cost:
- Panel and inverter quality: High-efficiency panels and premium inverters can increase the system’s cost but offer better long-term performance.
- Installation complexity: Roof type, shading issues, and whether tilt frames are needed can add to the installation costs.
- Government rebates: The Small-scale Renewable Energy Scheme (SRES) can lower the overall cost by approximately AUD 5,000 to AUD 6,000 depending on your location and STC value
A 13.2kW solar system offers substantial long-term savings, and while the upfront cost ranges between AUD 9,500 to AUD 14,000, government incentives can help reduce this investment significantly. With proper installation, the system pays for itself within 3 to 5 years, making it a sound investment for both residential and business users.
Inverter and System Performance
A 13.2kW system usually comes with a 10kW inverter. Although the system has a higher panel capacity, the inverter is designed to handle real-time energy production and grid requirements. Some systems may overclock, meaning they can produce slightly more energy during peak times like early mornings and late afternoons.
Considerations for Battery Storage
Adding a battery to your 13.2kW system can significantly increase energy independence by storing excess solar energy for nighttime use or during grid outages. A battery system is especially useful for businesses or households with high energy usage during non-sunlight hours.
What Are the Cost Implications of Adding a Battery?
The cost of a battery storage system varies by size and brand. For a 13.2kW system, you may require a battery size of 10 to 15 kWh. The price range is typically:
- Cost of Battery: AUD 10,000 to AUD 15,000, depending on the brand and capacity
What Warranties Are Included with a 13.2kW System?
Most 13.2kW solar systems come with robust warranties, including:
Panel Warranty
Typically 10-25 years for performance guarantees.
Inverter Warranty
Generally 5-10 years.
Workmanship Warranty
Installers often provide a 5-10 year warranty on installation work
