Ground-Mount Solar Installation Cost Per Watt Explained

Key Takeaways

• Ground-mount solar systems provide more flexibility in placement compared to rooftop systems and allow for optimal sunlight exposure.
• The average cost for ground-mount solar installations is around $53,800 before any tax credits.
• Cost per watt is an important metric in evaluating the value and efficiency of a solar installation project.
• Ground-mount systems may involve higher initial costs but result in greater energy output and savings over time.
• Nuance Energy’s patented earth anchor system technology reduces the time and costs of installing ground-mount solar systems.

What Is a Ground-Mount Solar System?

A ground-mount solar system is a solar power setup where photovoltaic (PV) panels are installed on the ground instead of on rooftops. This type of installation is ideal for properties with ample open land and is designed to maximize sunlight exposure with optimal panel orientation and tilt angles throughout the year.

These systems operate similarly to rooftop systems. Solar cells within the PV panels convert sunlight into direct current (DC) electricity. This DC electricity is then routed to inverters that convert it into alternating current (AC), which can be used to power homes or businesses or fed back into the electrical grid.

Ground-Mount Solar Installation Cost Per Watt: What Does It Mean?

Cost per watt helps you compare the efficiency of various solar systems.

The cost per watt ($/W) is a metric that’s calculated as the total cost of a solar installation divided by its total capacity in watts. This figure includes all expenses related to the installation, such as equipment, labor, and permits, but can also factor in incentives like tax credits. 

For example, if a solar system costs $20,000 to install and has a capacity of 5,000 watts, the cost per watt would be 4 dollars.

Importance of Cost Per Watt

1. Comparison Tool: The cost per watt serves as a standardized way to compare various solar installation quotes.
2. Budgeting and Financing: It provides clarity on how much property owners will need to spend upfront versus potential savings over time.
3. Market Trends: Tracking changes in the cost per watt over time can indicate broader trends in the solar market, such as technological advancements or shifts in material costs.

Factors Affecting Ground-Mount Solar Installation Costs

1. System Size and Capacity: The size of the solar system, usually measured in kilowatts (kW), directly impacts the installation cost. Larger systems require more equipment, including additional solar panels and inverters.
2. Type of Solar Panels: 
   1. Polycrystalline Panels: Generally less expensive, averaging around $25.5 per watt.
   2. Monocrystalline Panels: More efficient but costlier, typically around $30 per watt.
   3. Bifacial Panels: These can be even pricier, costing between $31 and $32 per watt due to their advanced technology and efficiency benefits.
3. Mounting Equipment:
   1. Standard Ground Mounts: Less expensive but fixed in angle.
   2. Pole-Mounted Systems: More costly due to tracking mechanisms that adjust the angle of panels to follow the sun throughout the day and maximize energy capture.
4. Labor Costs: Labor costs can vary widely based on the complexity of the installation and regional wage differences.
5. Location and Terrain: The geographical location and terrain of the installation site play an important role in determining costs.
   1. Accessibility: Difficult-to-reach areas may require additional equipment or labor.
   2. Soil Conditions: Certain soil types may necessitate specialized mounting techniques or deeper foundations.
6. Permitting and Regulatory Fees: Local regulations may impose permitting requirements that can add to costs. These fees vary by location and can include zoning approvals or inspections prior to installation.
7. Incentives and Tax Credits: Federal tax credits, such as the Investment Tax Credit (ITC), can significantly reduce upfront costs by allowing homeowners to deduct a percentage of their solar installation expenses from their federal taxes.

Frequently Asked Questions (FAQs)

What are the benefits of ground-mount solar panels?

1. Maximized Sun Exposure: They can be oriented and tilted to capture more sunlight throughout the day.
2. Easier Maintenance: Accessible at ground level, these systems simplify cleaning and repairs without the need for ladders or special equipment.
3. No Roof Modifications: They eliminate the risk of roof damage during installation and do not require structural assessments.
4. Scalability: Ground-mount systems can be expanded easily as energy needs grow.

How long does it take to install a ground-mount solar system?

The installation time for a ground-mount solar system can vary depending on the size and complexity of the project. Typically, a standard residential system can be installed in one to three weeks. This includes site preparation, system assembly, and connection to the electrical grid. But our Osprey PowerRack™ can reduce this timeline significantly due to its simplified installation process.

What maintenance is required for ground-mounted solar systems?

1. Cleaning: Panels should be cleaned periodically to remove dust, dirt, and debris that can reduce efficiency.
2. Inspections: Regular checks for any signs of wear or damage to panels or electrical components are essential.
3. Repairs: Occasional repairs may be necessary if any components are damaged or misaligned.

Are ground-mount solar systems worth it?

Ground-mount solar systems can be an excellent investment if you have adequate land space and can afford the initial costs. They provide higher energy generation potential, easier maintenance, and more flexibility in design compared to rooftop systems.
