Solar Zack puts solar panels on homes, and it can re-roof the house first. One customer said Zack re-roofed the house at a cost lower than their other quotes before installing the solar equipment. The company says it has been in business 10 years, operates in all towns in Vermont, New Hampshire, Massachusetts, Rhode Island, Pennsylvania, New Jersey, Maine and Florida, and offers a solar lease, PPA, purchase or financing. A customer who had put off solar for years said the company's work with local framers made it possible to consider more setups, including a solar carport, and that the installed panels produce just as estimated. A customer who had found a deal on panels said the large solar companies in the area refused to install panels they hadn't sold or leased; Zack installed them. One customer wrote that Nick got the installation done in one day. A customer who got estimates from at least three other solar companies said Zach's was the only reasonable one for what they said was important. A customer who had the team install a new roof said they were easy to reach with questions and praised the clean-up afterward. One customer said the only hold-up on their solar project was their electric provider. Vermont lists its residential contractor registration, 173.0000726, as active, held by Zackary Mostov.
I found it effortless to arrange rooftop solar with Zack. We put off solar for years because options from national installers were unwieldy. Working with Zack was a breeze. He's a Vermont local with an excellent reputation around town, where he's done just about every roof. Communications were efficient, thoughtful, and concise. Zack's partnerships with a local CU and other local service providers made the entire process self-executing. Because the company works with local framers, it was possible to consider a broader range of setups, including a solar carport. Pricing and contract terms were fair and competitive. And most important, the installed panels look great and produce just as estimated. We are satisfied in every respect and would recommend Solar Zack without reservation.
I don’t think the experience could have been any better than it was. Zach communicated clearly and often, and his crew were efficient and kind. This is the exactly what you’re looking for when hiring someone to do work. I couldn’t recommend his business highly enough!
Zack was genuine and pleasant to work with. My husband and I were very pleased with the entire experience, from consultation to installation. 100% recommend him.
Solar Zacks team did a great job installing our new roof. Easy to communicate with and was always available to answer any questions. Did a great job on clean up after the roof was completed.
Zack's team works fast. Our new roof is great!
