Why site surveys are important
Before installing solar panels, a site survey is usually necessary to confirm that the building roof can safely carry the system. Surveys reduce risks, identify potential challenges, and help plan a layout that maximises energy generation.
What a survey typically entails
During a solar site survey, a surveyor or engineer will assess:
- Roof structure, including rafters, trusses, and support spacing
- Condition and age of roof coverings
- Orientation, slope, and shading from nearby objects
- Access routes for installation and future maintenance
- Potential obstacles such as vents, chimneys, or HVAC equipment
- Electrical infrastructure for connecting the solar system
- Local regulatory or planning requirements
Charges for surveys
Some solar providers include the cost of a survey in their quotation, while others may charge separately. The fee can vary depending on property size, complexity, and whether structural or electrical assessments are needed.
How to arrange a survey
To get a solar site survey, contact a solar installer or survey provider and provide basic property details. They will schedule a visit, usually during normal working hours. For commercial buildings, multiple areas may be inspected, including roof structures, access points, and electrical connections.
What happens after the survey
The survey typically results in a report outlining suitability, required reinforcement, panel layout options, and any regulatory considerations. This report forms the basis for an accurate quotation and safe installation plan.
Benefits of completing a survey
Completing a survey before installation helps prevent costly mistakes, ensures compliance with safety and building regulations, and allows for optimal solar energy generation. It gives property owners a clear understanding of what is feasible and how the system should be installed.
For most properties in the UK, a solar site survey is the most reliable way to ensure the roof and building are ready for panels.
