What Solar Panel Installation Involves
Installing solar panels is a significant investment for both residential and commercial properties. The process typically involves system design, followed by installation of the solar panels themselves, which are usually mounted on rooftops or ground-mounted systems. Durable solar panels are often made of silicon, and the installation generally adheres to local building codes such as the National Electrical Code (NEC).
When You Need Solar Panels
You may want to consider solar panel installation if you're looking to increase property value. However, if your roof is shaded, it might be not worth it to wait until you can make necessary improvements.
The Installation Process
The installation process typically unfolds in six main steps: 1. Energy assessment, 2. Permitting, 3. Panel setup, 4. Inverter installation, 5. System testing. Each step can take anywhere from a week depending on the size of the system and local permitting processes.
Timeframe for Installation
On average, the entire process from consultation to activation can take 4 to 8 weeks. Factors affecting this timeframe include weather conditions.
