Ground-Mounted Solar System

Ground-Mounted Solar System

What is a Ground-Mounted Solar System?

A ground-mounted solar system is a solar energy installation where the panels are mounted on the ground instead of being placed on a rooftop. These systems are particularly beneficial for homes and businesses that either lack sufficient roof space or want to optimize solar production by placing the panels in an ideal sun-facing location. Ground-mounted systems offer flexibility in positioning, allowing you to choose the best orientation and tilt angle for maximum solar efficiency.

How Many Solar Panels Does a Ground-Mounted Solar System Have?

The number of panels in a ground-mounted system depends on the system’s capacity and the wattage of each solar panel. Typically, for a standard residential 6.6kW system (a common size in Australia), you would need around 13 to 15 panels, assuming each panel produces between 440W to 500W. However, larger systems can require more panels.

System Size (kW) Number of Panels (440W) Number of Panels (500W)
6.6 15 13
10 23 20
20 45 40

How Much Electricity Does a Ground-Mounted Solar System Produce?

The electricity output of a ground-mounted solar system depends on several factors, including system size, location, panel orientation, and sunlight exposure. A 6.6kW system typically generates between 22 to 27 kWh per day in optimal conditions​.Larger systems like a 10kW system can produce up to 40 kWh daily, depending on sunlight hours and weather conditions.

System Size (kW) Daily Output (kWh)
6.6 kW 22–27
10 kW 36–40
20 kW 72–80

What are the NSW Rebates for Ground-Mounted Solar Systems?

In New South Wales (NSW), homeowners can benefit from the Small-scale Renewable Energy Scheme (SRES), which provides upfront discounts through Small-scale Technology Certificates (STCs). The value of these certificates depends on system size, location, and market factors​.Other incentives include potential state government rebates and low-interest green loans for solar installations

How Long Will it Take for the System to Pay for Itself?

The payback period for a ground-mounted solar system varies based on the upfront cost, electricity consumption, and local solar rebates or incentives. Typically, a system pays for itself within 4 to 6 years due to savings on electricity bills and possible income from feed-in tariffs (FiTs)​

What is the Cost of a 6.6kW Solar System?

Ground-mounted systems generally cost more than rooftop systems due to additional requirements like mounting hardware, site preparation, and sometimes trenching for electrical connections. A 6.6kW ground-mounted system typically costs between AUD 7,000 and AUD 12,000, whereas larger systems (e.g., 10kW) can range between AUD 15,000 and AUD 20,000​

System Size (kW) Cost Range (AUD)
6.6 kW $7,000 – $12,000
10 kW $15,000 – $20,000
15 kW $20,000 – $30,000
20 kW $25,000 – $35,000
30 kW $35,000 – $50,000
50 kW $60,000 – $85,000

This table provides an estimate based on system size and cost, which can vary depending on factors such as site preparation, component quality, and local regulations​

Inverter and System Performance

Most ground-mounted solar systems are paired with a 5kW to 10kW inverter. Inverters convert the direct current (DC) generated by the solar panels into alternating current (AC) for use in the home. Higher-quality inverters offer better efficiency and longer warranties. Additionally, you may consider a micro-inverter system to maximize output when partial shading occurs on parts of the array​

Considerations for Battery Storage

Adding a battery to your ground-mounted solar system allows you to store excess solar energy for later use, especially during nights or power outages. Battery storage systems are ideal for properties that experience frequent grid issues or for homeowners looking to achieve energy independence​

What Are the Cost Implications of Adding a Battery?

The cost of adding a battery to a ground-mounted solar system depends on the battery size. Typically, a 5kWh battery costs between AUD 6,000 to AUD 8,000, while a larger 10kWh battery can cost between AUD 10,000 to AUD 15,000. The addition of a battery can extend the payback period but provides long-term energy security and additional savings during peak electricity pricing​

What Warranties are Included with a Ground-Mounted System?

Most Ground-Mounted 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​
