The permitting process may vary depending on different factors. For example, to install solar PV panels on buildings in the City of Colwood without a building permit, the installations must comply with the following criteria:

  • The PV system’s total weight must not exert a load greater than 24.4 kg/sq. M (5lbs/sq. ft.) on the roof.
  • Each point of connection between the system and the roof must be less than 22.5 kg (50 lbs).
  • The PV panels must be flush mounted on existing construction in an approved manner as per the manufacturer’s installation instructions.

If anything exceeds the described limitations, the solar installation company will handle the permitting process for you. This process typically involves obtaining a general electrical permit, an electrical wiring permit, and a construction permit. Once the permits are obtained, the solar fitting can begin.

Procuring Materials
