Powerhome Solar is among the nation's fastest-growing energy companies.
However, it's facing complaints of botched installations and unresponsive customer service.
Among the 11 unhappy Powerhome Solar customers Business Insider spoke with, some say they were stuck with expensive panels that don't work.
And while the Better Business Bureau gives the company an A+ rating, the company has had 183 complaints made against it.
The vast majority of the complaints registered with the BBB were categorized under 'Problem with a Product or Service.'
