I would have rated them 4+ stars for initial sales, installation and overall pricing and Warantee that they claimed to provide. Once installation was complete I feel that rating has nose dived with the bad experience so far.
First they promised they will give referral fee right away a day after the installation. It has been 1 1/2 years and they have not paid and they keep pushing me off with lip service. I have sent multiple emails and called multiple times.
Second issue is one of my panel was not performing and it’s producing 33% less energy then others, I found the issue instead of them and reported it to them in March and till now I have to call and follow up but no action has been taken yet since 4+ months. Still waiting for help.
Slingshot power is one of the worst businesses I've ever dealt with.
I originally went with them because I wanted to support a local business and Paul seemed like a friendly guy. Unfortunately the friendliness was a total farce. They took no time in collecting my money for a solar install, however after that there were so many delays that 3 weeks after my initial install date I decided to cancel my contract with them.
It's been 2 weeks now and I still haven't received my refund. They are impossible to get a hold of on the phone and even if you do manage to get a hold of them they keep making promises which they never go through with.
Please read the reviews here and think twice before doing business with them.
