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 inspects 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 helps in identifying potential shading issues, and infrared cameras to identify energy loss areas.
When Do You Need a Solar Energy Audit?
You might need a solar energy audit if you're noticing reduced energy output, considering a new installation, or evaluating system upgrades. Conversely, if your system is producing expected energy, an audit may not be necessary. Regular audits every 1-2 years can help maintain 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 issue a detailed report with insights on improvements and potential savings. The entire process usually takes 2-4 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 assist in analyzing energy performance. Compliance with standards such as the National Renewable Energy Laboratory (NREL) guidelines ensures a thorough evaluation.
