What is Commercial Solar?
Commercial solar entails the installation of solar panels on industrial properties to generate renewable energy. This power can offset utility bills significantly, especially for businesses with high energy consumption.
When You Need Commercial Solar
You could evaluate commercial solar if your business has a substantial roof space and high electricity costs. If your energy bills are over $1,000 per month, solar can be a smart investment. However, if you operate a small business with low energy needs, the initial costs may not justify the investment.
The Commercial Solar Process
The process of deploying commercial solar usually includes the following steps:
- Site Assessment: A professional will evaluate your space to determine suitability for solar installation.
- System Design: Engineers will design a custom system using tools like PVsyst and AutoCAD, ensuring it meets your electricity needs.
- Permitting: The installation team will handle all necessary permits, adhering to local codes and regulations.
- Installation: Solar panels will be installed, usually using racking systems and inverters from reputable brands like SMA or Enphase.
- Inspection: A final inspection will be conducted to ensure compliance with safety standards and efficiency.
This entire process typically spans 3-6 months, depending on local regulations and the size of the system.
How Much Does Commercial Solar Cost in Chicago?
Understanding the Costs
The cost of commercial solar can fluctuate significantly based on several factors. On average, you can expect to pay:
- Low end: $15,000 for small systems (10-20 kW).
- Mid-range: $50,000 for medium systems (50-100 kW).
- High end: $200,000+ for large systems (over 100 kW).
Factors that affect pricing include capacity, type of solar panels (monocrystalline vs. polycrystalline), and installation complexity. Government rebates can also significantly reduce your net investment, typically around 26% of the total cost under federal programs.
