Two best things were: the company is local and the installer visited my property and did a roof and shade survey to enable optimization on my property. Charles, the owner, talked me through the whole process. He explained to me the need for optimizers on one of my roofs because of shading, and recommended 4000 watt panels to maximize output with minimum number of panels. The whole process was completed without any sales pushy dialogue. I was given plenty of time to mull over a couple of options. I had three other quotes from other companies: none came close to the price and quality quoted by Sky Energy Solar. The installation went smoothly without a hitch. The two installers arrived on time, were polite, tidy, most importantly the chief installer, Matt, was very professional and did a great job. I have no hesitation in recommending this company: thank you Charles and Matt.
