A building permit is required for solar panel installation when the accumulated face area is greater than or equal to five meters square (approximately 54 feet squared).
Project preparation
Detailed information is required to properly evaluate your plans and the unique conditions of your property or unit.
An engineer is required to assess the building structure that the solar panels will be installed upon.
For electrical work, contact the Electrical Safety Authority at 1-877-372-7233 or email esa.cambridge@electricalsafety.on.ca.
Heritage approval is required if you plan to install the solar panels on a heritage designated property. Learn more about heritage planning.
