What is Commercial Solar?
Commercial solar entails the installation of solar panels on industrial properties to harvest renewable energy. This power can offset utility bills significantly, especially for businesses with high energy consumption.
When You Need Commercial Solar
You might want to think about commercial solar if your facility has a large roof space and high electricity costs. If your energy bills are more than $1,000 per month, solar might 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 property to determine viability for solar installation.
- System Design: Engineers will design a custom system using tools like PVsyst and AutoCAD, ensuring it meets your energy 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 takes 3-6 months, depending on local regulations and the size of the system.
