Selecting a Solar Energy Contractor
As with any business, evaluation of contractors is important when investing in clean energy technologies. Because solar arrays can produce large quantities of electricity, only qualified professionals should install PV systems.
Obtain several quotes prior to selecting a contractor. Inquire about what is included in the quoted price. Some contractors will include related electrical work performed by a licensed electrician, others may not. Work completed ‘downstream’ of the inverter must be performed by a licensed electrician to insure compliance with National Electrical Code (NEC) and local building codes.
Check with your solar professional about whether they will complete required paperwork for cost-sharing from utility companies or if this is the responsibility of the customer. Typically the utility-based incentives will be paid after the installation is complete and the net meter is installed. Check with your contractor about whether they will finance the utility payment and other payment schedule details.
Inquire about any warranties offered by the contractors and equipment manufacturers. PV panels have long useful lives, so it is not unusual to see power-output warranties of 20 to 25 years. Batteries and other components will have a much shorter warranty coverage. Ask for references and any certifications they may have. You will be investing several thousand dollars into equipment and labor.
Solar professionals should be able to provide numerous references and details about their experience and training. The North American Board of Certified Energy Practitioners (NABCEP) offers a credentialing program for clean energy professionals. NABCEP certified professionals have completed educational requirements and practical, hands-on experience to be certified by this professional association. This type of certification may be of value to a clean energy customer, but should only be one part of the selection process. Several quality solar professionals are available that are not necessarily NABCEP-certified.
