The cost of a commercial solar system depends on its size and can range from $10,000 to $50,000 or more. This is an estimated price for 10-20kW solar systems without any special configurations or extras. Larger systems (30kW and above) will naturally cost more but offer better cost per watt, thanks to the benefits of large-scale production.
Investing in a commercial solar system can be a smart financial decision for businesses looking to reduce energy costs and improve their carbon footprint. However, understanding the costs involved is crucial to making an informed investment.
Understanding the Costs
The cost of a commercial solar system varies based on several factors such as the size of the system, the technology used, and installation specifics. In Australia, a good quality commercial solar system will cost between $950 and $1,200 per kW installed. This pricing includes high-quality components and installation services, ensuring durability and performance.
Cost Breakdown by System Size
The cost of a commercial solar system in Perth can range from a few thousand dollars to over half a million dollars depending on the size of the system. To provide a clearer perspective, let’s break down the typical costs associated with different system sizes:
20kW to 30kW Systems
These smaller commercial systems are popular for small to medium businesses such as retail outlets or clinics. The cost for a 20kW to 30kW system generally ranges from $20,000 to $35,000. These systems are suitable for businesses that consume a moderate amount of energy and wish to offset some of their utility costs. A 20-30kW system will require at least roughly 100-200m² of roof space.
50kW Systems
A 50kW system can be a suitable choice for businesses with higher energy needs. The estimated cost for these systems is between $55,000 and $70,000. A 50kW system can significantly offset energy bills, making it a popular choice for larger businesses. A typical 50kW solar system will require at least roughly 400m² of roof space.
70kW and Above Systems
Larger systems such as 70kW or 100kW are ideal for large operations such as farms or warehouses. These systems can cost anywhere from $70,000 to $120,000, depending on the specific requirements and components chosen. These systems provide significant savings by reducing peak energy demand charges.
Factors Influencing the Cost
Several factors can influence the final cost of a commercial solar system:
- System Cost (Upfront and Ongoing): High-quality solar panels, inverters, and mounting systems tend to cost more but offer better efficiency and longer lifespans.
- Installation Complexity: Roof type, building height, and structural integrity can add to installation costs. Some roofs may require reinforcement or additional safety measures, affecting the price. Some systems may require switchboard upgrades, crane hire and ground-mounting systems.
- Location: Costs may vary based on your location due to differences in local solar rebates, installation labour rates, and availability of components.
- Rebates and Incentives: Government incentives like Large-scale Generation Certificates (LGCs) can substantially decrease the upfront cost of a solar system.
- Solar Feed-in Tariffs: Some smaller commercial solar systems are eligible for a solar feed-in tariff. In Perth, the Southwestern region has solar feed-in schemes for 10kW (single phase) and 30kW (three phase) systems.
- Energy Usage Patterns: The specific energy consumption patterns of a business can determine the optimal system size, which in turn affects cost.
Benefits of Commercial Solar Investment
Despite the initial investment, the long-term benefits of installing a commercial solar system can be substantial:
- Reduced Energy Costs: Electricity costs can be significantly reduced, allowing businesses to allocate funds to other operational needs.
- Return on Investment (ROI): Most solar systems pay for themselves within 3 to 7 years through the savings generated on electricity bills.
- Energy Independence: Businesses can reduce dependence on grid electricity, safeguarding against future electricity price rises.
- Environmental Impact: Solar power creates clean energy, reducing your business’s carbon footprint and contributing to global sustainability efforts.
