Ask these questions to be sure the contractor knows the business thoroughly and has satisfied other customers. Also, be sure to request copies of insurance documents, certifications and licenses, so you know that the contractor and installers have gone through required training. Be sure to call former customers and check out other installations the contractor has completed. You should query local Better Business Bureaus and your state Attorney General’s office, and check online rating services for comments about the contractor and the equipment you plan to purchase.
- How long have you been in business?
- Are you licensed to do business in my state?
- How many PV systems have you installed? Can you provide a list of consumer references in my area? Can I talk with former customers and also see successful installations?
- Who will do the installation at my site? Are they employees or subcontractors? If you involve subcontractors, do they work with a number of other employers, too? Have these subs worked on many of your installations?
- What training have you and your installers had, and what, if any, certifications do you and your installers hold? Do you have an installer with a Master Electrician license, and is there an installer on your team licensed to install solar?
- Does your company carry these types of insurance: general liability for at least $1 million, professional liability, workers compensation, other types?
- Have you ever been involved in a legal dispute involving a solar installation?
