I had this company in and they talked about how you a credit score or 680 to get the SPECIAL lease program. I had just bought a car 4 weeks before and paid cash but they still had to pull my score, it was over 700 but the one form solar concepts came back as, this bothered me a lot so I have called Transunion 3 times(solar concepts says they only use Transunion) and three times I have been to that 663 is NOT MY SCORE and that solar concepts (part of sunpower based in San Jose) actually does something else to the score so it is not your usual credit score to bring it down presumably so you fail to qualify for the lease program. I am sure you would pass if you were to BUY the system. I dislike companies who play games. So SUNPOWER/ARIZONA SOLAR CONCEPTS you get my vote of NO CONFIDENCE.
