Record the surrounding obstructions
Energy Saving Trust identifies shading from nearby trees and buildings as a factor affecting solar panel performance. Its advice is written for building-mounted solar panels, but it provides a helpful general reason to document obstructions around any proposed solar collection position. The lighting application still needs its own assessment.
Photograph the location, not just the ground
Include views towards the skyline as well as the area to be lit. Mark nearby trees, buildings, walls and any other features that could be relevant. If you know the orientation of the site, include that on the plan. Use photographs as a starting record rather than a substitute for a proper assessment.
Separate the light position from the collection question
A location can look convenient for illuminating a route while raising questions about solar collection. Show both the lighting objective and the surrounding conditions in your enquiry. Ask which locations should be reviewed before treating a layout as settled.
Keep the information current
Record the date the photographs were taken and note planned building or landscaping changes. Where the site changes through the year, describe what you have observed. A clear record helps the project team identify uncertainties and decide whether further information is needed.
Bring these points to the conversation.
- Send a site plan or marked location image.
- Include skyline views and nearby obstructions.
- Record photo dates and known orientation.
- Mention planned buildings or landscaping changes.
