Report
Had a couple of guys from MJJs solar come out to do some maintenance on our panels and fix a leak near one of the solar panel mounting brackets a couple of weeks ago. We were incredibly impressed with the service we received. The two guys who came out went above and beyond to ensure that the leak was fixed and no more water could get in. They did a great job cleaning the panels and even sorted out the wifi connection on our inverter. Highly recommended

When considering the installation of a solar system I contacted five providers asking for a proposal and quote. MJJs was one of only two who bothered to actually visit our home. Steve, our initial contact inspected the site then sat down with us for over two hours to learn of our requirements and educate us regarding solar. The MJJs price was competitive, communication throughout was excellent and delivery and installation were timely. The installation team, led by Paul, were communicative and courteous and made every effort to conform fully with my preferences for the location of the electrical

Great Service all around. The sales person was very knowledgable and professional, i had 3 seperate companies come onsite and quote and the other 2 installers spent 15 mins max onsite. MJJ's sales person spent over an hr onsite with me asking me all the questions he needed and explained to us every component and recommendations for panels invertors etc and the reaaons behind his recommendations. He even went into depth about how the installers will install the system on the roof etc and the connectors and fire saftey precautions they put in place.

From day one when Steve came out physically to assess and explain what might be best layout, Jo and the team explaining everything to expect, and the physical installation of the Panels. Very professional and reliable. Very happy. Probably couldnt have chosen a better company for a big investment like this.
