Quick Answer
Identify potential future shading risks by observing nearby growth, trees, and structures that could cast shadows on your solar setup. Consider using online tools or consulting with a solar expert to assess your site's shading risks. Analyze the sun's path throughout the year.
Assessing Shading Risks
When evaluating potential shading risks, start by observing your site’s surroundings. Look for nearby trees, buildings, or other structures that could cast shadows on your solar panels. Consider the mature size of any nearby trees, as well as their growth rate, to determine when they may start to shade your panels. For example, if a tree is 10 feet away and expected to grow 3 feet per year, it may start to shade your panels in 3-4 years.
Using Online Tools
To further assess shading risks, utilize online tools such as the National Renewable Energy Laboratory’s (NREL) PVWatts Calculator or Google’s Project Sunroof. These tools can help you simulate shading patterns and provide a more accurate assessment of your site’s solar potential. Enter your site’s location, solar panel size, and other relevant information to get a detailed analysis of potential shading risks.
Best Practices for Mitigating Shading Risks
To mitigate shading risks, consider the following best practices. If possible, install solar panels at a slightly higher angle to reduce the impact of morning and afternoon shading. Use a solar panel tracking system to follow the sun’s path and maximize energy production during peak hours. Alternatively, consider using a different solar panel configuration, such as a south-facing roof installation, to reduce shading risks.
