    We really enjoyed working with Eric, Zack and crew. Working with Eric is like working with family. He provided exceptional customer service from start to finish. We're very appreciative and the install went great.

    I cannot say enough great things about NexGen Construction. From the initial informational get together to the installation and final debriefing, NexGen Construction knocked it out of the park. Eric and his team are genuine, approachable and honest. I work the night shift and they went out of their way to accommodate my sleeping pattern and my crazy dogs antics. Eric was able to personalize the solar system, payment plan and installation to my family and my needs and schedule. If you are looking to install solar panels, look no further, you cannot go wrong with NexGen Construction!

    From the very start Eric was honest, patient, and knowledgeable about the whole process. I had already gotten 2 other quote from other solar competitors and Eric was never pushy and always willing to answer any questions I had regarding my possible installation. When I finally decided to move forward with solar I knew Next Gen was who I was going to go with, from his friendly service, to his knowledge on the products and of course this price as well. His installation team was very polite and friendly, always cleaned up there mess every day and made any adjustments to my system as I requested. Over all I am clearly happy with the service I’ve received from Next Gen and would definitely recommend them to all my friends and family. Last note… After completion I asked him to review another property I have downtown HB, after he reviewed it, he came to the determination that it would be in my best interest financially to obtain the solar at that house do to location, roof space, and my ROI (return on investment) one last reassurance that Eric is a very ethical man and will not take to work without letting you know the facts.

    Thanks again,

    NexGen was recommended by a friend. They were professional and timely throughout the entire process. They took care of everything, and made everything easy. Eric is very enthusiastic about his business and his products. It was a pleasure.

    Eric did a great job on our 10 panel installation and had the lowest quote. Returned phone calls promptly. Recommend him for any solar project.

    We had solar electric for our home and solar thermal installed for our pool. I am attimate about getting what I pay for. NEXGEN presented a good explanation of how things would work, was at my home when they were scheduled and completed the 2 installations without a hickup. I would recommend NEXGEN to anyone considering solar or thermal and looking to save money.

  • "Great experience with NexGen"

    Reviewed Feb 12, 2018

    I have talked with multiple solar providers over the last 15 years. Every time the price was more attractive. Several times I was close enough to making a decision that I used Yelp to check out the vendor. I read plenty of horror stories that made me put off making a decision - people not showing up, nobody returning calls, installers where nobody on the crew spoke English, etc.

    I picked NexGen because their Yelp reviews were stellar (check them out yourself) and I felt that Eric (the president) was a no BS guy I could count on. He didn't disappoint me. My installation started on Thursday morning and by Friday afternoon I was making electricity. The NexGen crew was a great bunch of guys. Everyone spoke English and happily answered any question I had. The installation is very clean looking with wiring going thru the attic instead of strung across the roof like I've seen with so many other solar installations.

    The following Monday Eric came by to show me how to monitor my system and answer any remaining questions I had. The HB city inspector came by the same day and signed off on everything. I can't believe how quickly this all happened. I have total confidence that this guy is going to be there if I have any problems. He always answers his cell and there is no runaround when you try to reach him. The ball is now passed to SCE to do their thing with my billing.

    I would recommend NexGen to anyone.

  • "NexGen is the best"

    Reviewed Oct 31, 2017

    We were motivated to look at solar after purchasing a townhome that our son and his family live in. The townhome is all electric. We interviewed a number of companies and we were so impressed with Eric at NexGen that we put solar panels on both the townhome and our two story single family home. Eric did an amazing job educating my wife and me about all the options in products and design. Eric worked very closely with us getting the needed approval from the HOA for the townhome and obtaining the permits needed from the city. The solar panels have exceeded expectations. I highly recommend that folks seriously consider solar panels and when you decide to move forward, I highly recommended you call Eric at NexGen. Eric and his team of installers are terrific.

    I started looking into solar in 2013. By chance the first company I contacted was NexGen Construction. At the time I was in the investigative phase, not anywhere near ready to commit to an installation.

    Eric, NexGen Construction's owner was very helpful in educating me on solar. He spent this time helping me come up to speed even though he knew I was not ready even to decide if solar was right for me much less sign a contract. This was in June. I spent that month and July checking out installers and confirming that solar was a good investment for me. I winnowed down companies to three candidates.

    NexGen Construction gave me a good deal. But more important the dealing with them both in my investigative stage and in the purchasing process made me feel confident in their product and service. I felt it important that my provider was a full service company, not a contractor who relied on fleeting subcontract labor.

    It is five years later when I write this review. Three of my friends have also used NexGen Construction for their solar installations. I believe they have also passed down the recommendation to their friends. All of us are totally satisfied with the work and product.

    The system has consistently been out performing its estimates by somewhere between 5 and 20 percent a month. My electricity costs are essentially nothing now, so I am saving over $2000 a year. This is based on the cost of electricity five years ago. I have not recomputed based on today's rates, but rest assured the savings are greater now. These savings are equivalent to a tax free investment that returns better than 10% a year. Where else can you find that kind of a safe investment?
