What is a Solar Energy Audit?
A solar energy audit entails a comprehensive evaluation of your commercial facility to determine the efficiency of your solar energy system. This process typically examines the layout, orientation, and shading of your solar panels, along with your energy consumption patterns. Certified auditors often use tools such as a solar pathfinder, which assists in identifying potential shading issues, and infrared cameras to detect energy loss areas.
When Do You Need a Solar Energy Audit?
You might need a solar energy audit if you're seeing reduced energy output, considering a new installation, or evaluating system upgrades. Conversely, if your system is meeting your needs, an audit may not be necessary. Regular audits every 1-2 years can help optimize performance.
Step-by-Step Process
The audit process typically begins with a site visit, where the auditor will assess your current solar setup. This is followed by an analysis of your energy bills and usage patterns. The auditor will then provide a detailed report with recommendations on improvements and potential savings. The entire process usually takes about 2 to 4 hours, depending on the complexity of your system.
Tools and Techniques Used
Common tools used include energy monitors to measure sunlight availability and energy output. Auditors may also apply the Energy Star Portfolio Manager to aid in analyzing energy performance. Compliance with standards such as the National Renewable Energy Laboratory (NREL) guidelines ensures a thorough evaluation.
