The solar panels have not worked since they were put in has not saved us any money or earned us any credits the Errol seal ductwork was also a joke has not eliminated or reduce any allergens that was promised to us when it was done. Our electric bill does not show that global white green was excepted as a clean energy company and to this day we have not seen any reduction in our electric bill it was a total waste of money the job was very sloppy extremely unprofessional and messy !!
