Nigel presented effective, professional, concise and easily understood solutions for an excitingly cost beneficial system. I am recommending him and his product to every homeowner or client that I find receptive. He is a pleasant and responsive experience.
I would like to give two thumbs up to Nigel and the entire Solar teams. I met Nigel through my neighbor Ms.Angela. Ms.Angela inform me about Nigel and the company in which he work. I scheduled an appointment with Nigel to gain some knowledge about solar panels. Nigel informed me about the Solar Program and how this all worked. Nigel took the time to explain it to me, so I totally understood everything. Nigel then walked me through the process and showed me how the design of solar panels would work, where they would go on my roof and how much my savings would be. Nigel made be feel confident and happy in my decision to go solar. Nigel was there for me through the entire process and I am truly grateful. I am extremely happy with my purchase and strongly recommend my friend to contact Nigel and get Solar from this company too. I would like to say thank you again to Nigel, for helped me through the process from beginning to the end.
Nigel is a thorough professional . I had a very good experience with him handling the project between various contacting agencies and Solar Compnay.
They’re giving you a good information and I’ll be happy with
My sales person Nigel is a very pleasant well mannered respectful person.
My consultant, Nigel, McFarlane was professional, responsive and extremely helpful. The process can be difficult due to multiple parties involved but he always made sure to keep me posted and move things along when he could. Very pleasant to talk to and extremely knowledgeable. Would highly recommend.
Nigel was a pure pleasure to work with, from the time we discussed my energy requirements, financial goals, future plans to acquiring multiple proposal from various solar providers, working on various energy options, various commercials options and most importantly the detailed analysis and inputs from him explaining each aspect to make the right choice. I am glad and extremely happy to have Nigel's guidance and knowledge all through the process to make the right choice. It doesn't stop there, he has also been very professional and responsive post the contract signatures with the Solar provider and provides his valuable checks whenever it is necessary. So in summary 5 stars from me to Nigel and his company for a well round professionalism, expertise and personal touch in making me a happy customer. Thank you Nigel.
Nigel McFarlane was my consultant. He walked me through the entire process and made sure I understood all the paperwork. Because of my area I wasn't able to mount my panels on the roof, so I had to utilize a ground mount. He came out to the property measured things up and took the time to explain the protocol. He also responded to every text or phone call I made to him. If your looking into solar and chose to use One Solar Energy make sure you request him specifically. You will not be disappointed!
I worked with Nigel Macfarlane at One Source Energy on my Solar proposal and installation. Nigel did a great job, walking me through the process and was always available to answer questions and provide updates. He was extremely patient and did a great job explaining the setup and the different options that were available to me. I've got the system installed and waiting for Permission to Operate.
Very professional and knowledgeable staff. The information was very clear and easily understood. They made the process very simple. Will definitely recommend them to our other friends looking to go solar. Now we're paying alot less per month for energy. We can monitor the amount of energy pir panels are producing as well as how much power we have used. Going solar was the best decision. No more high and unpredictable bills we know exactly how much we'll be paying every month, no matter how much power we use. Thanks One Source!
My roof was over thirty years old, and I got a new roof without any money out of my pocket. Now I'm in the process of getting solar with state incentives. Thanks so much One Source Energy for making this all possible, I will tell it wherever I go.
