Determine the installation services that your installer offers in-house. Some providers subcontract these services to reduce labor costs.
A licensed electrician or plumber may be required to take out a permit and be responsible for all electrical connections on site.
To reduce risk and protect all parties, you may decide to give preference to certain providers based on the degree to which their installers are trained in solar technologies. Anyone working on site must also be insured by the Workplace Safety and Insurance Board.
For Solar PV, if you are connecting to the electrical grid, understand your obligations with the local utility. Ensure your solar provider is also aware of its obligations, and capable of following through with them.
