Due to the environmental necessity, solar panel technology continues to be developed and is appropriate for residences. Solar installers have developed financially accessible options for installing solar, primarily through leasing. The Arizona residential solar module industry has grown and is competitive. Four solar installers, SolarCity, Sunrun, SunPower, and Sungevity, are leaders in the industry nationally and statewide and possess many effective marketing strategies along with some opportunities for improvement. SolarCity offers financing options and is full-service. It is the largest residential solar company that others tend to emulate. Sunrun is more unconventional but has a president who has helped its marketing with her appearances. SunPower runs a network of local solar dealers and takes a hands-off approach to the process. Sungevity has the potential to learn from these installers and can enhance its brand even further. It can focus on targeting young, new homeowners and can follow Apple's style of clean and concise materials. By emphasizing customer service, using guerilla marketing techniques, and following Cialdini's theories on persuasion and influence, Sungevity can be the leader in the Arizona residential solar module industry.
