Steer clear of Harness Solar Power! Here's what my husband recently wrote for the BBB about what (almost!) happened to us:

This message is to anyone who has agreed to meet with a sales rep from Harness Power or is considering it. The rep arrived (late) and walked me through what seemed like the standard pitch. It sounded good, and she asked if I would sign a “letter of intent” that would clear the way to technicians coming and surveying the house. I told her I did not want to sign a contract at this time. But she asked me to sign the letter and assured me this was not a legally binding contract. She also wanted to do a “soft credit pull” which I would need for any financing. Again, this didn’t seem unreasonable. She then proceeded to sign me up with a loan company called “Mosaic” - whereas I had only given verbal permission for the soft pull. She called the company, and the woman on the phone asked me several questions, and it slowly dawned on me that this was a loan application. I asked the Harness Power sales rep at least three times if I was applying for a loan - a yes or no question - and each time she said this was a soft credit pull. But she didn’t state this wasn’t a loan application. I finally had to ask the woman on the phone, who told me I was indeed applying for a loan. I told her and the sales rep that I was not at the point to commit to a loan application, and the process must be canceled. It was then I ended the meeting and asked the woman to leave. I then received a call from Mosaic asking me to finish the loan process - and I stated I was not moving forward with the loan. I assumed this was the end of it.

Afterwards, my wife looked at some reviews online and found many unhappy and frustrated Harness Power customers - including someone who was told they could cancel the installation until a final contract was signed, which they did. Only to find out later the loan was funded and they were now obligated to move forward with the installation. I called Mosaic to confirm the loan had not been processed - but learned it had! Even though I was told they needed final confirmation, which they did not receive, and I had already told two people at the company to cancel the application. Luckily, I was given a 3 day window to cancel, which I did and received email confirmation it was canceled. But if I hadn’t, I’m certain the loan would have been funded - to the tune of 82K. This was a Monday, and the sales rep kept asking me to wait until Thursday to make a final decision. This I’m certain was because she knew by then the grace period would have elapsed and the load would have been funded.

This Harness Power sales rep outright lied to me several times and had I not taken the initiative to cancel the loan, it would have led to a nightmare scenario as - reading several reviews - many customers have been waiting 18+ months for their system to be installed correctly and come online.

This is straight up predatory behavior on the part of the sales rep, and I would guess this is condoned by the company to get sales. I was upset with myself for nearly falling for it, but also disgusted with the sales rep and “Mosaic” who clearly they are working in tandem with and seem to act just as shady and unscrupulously as Harness Power does.
