  • "Great Contractor!"

    Reviewed Apr 11, 2021

    It was my original intention to obtain three quotes for installation of my residential solar system. I first contacted Sunrun through Costco. My experience with Costco's in-store salesman was generally positive. That's where the positivity ended - right there in the store. He then scheduled a virtual presentation with their technical staff. That presentation did not go well. The technical staff member started off on the wrong foot by asking me to provide info I had already submitted on-line and emailed to the in store salesman. Then she asked me whether I would like a quote for an outright purchase, a loan or a lease. I requested quotes for all three so I could compare alternatives. She said her software could only provide one quote, not three. During the next hour, I asked numerous questions, many of which the tech salesperson was unable to answer (including why she was proposing to place solar panels on the north facing roof of my home). I followed-up our virtual conversation with a detailed email requesting further information. I never heard from Sunrun again.

    For my next quote, I reviewed solar contractor recommendations on the social media site Next Door. After seeing several positive recommendations for NexGen, I decided to contact Owner Eric Helgeson. He promptly scheduled a virtual meeting with me followed by an in-person meeting at my home, at which time his accompanying staff members surveyed and measured my roof in preparation for coming up with a proposed solar layout. Within a few days, Eric presented me with several digital layouts with different panel quantities and locations. Eric then worked closely with me in coming up with an economically optimal design - not one which overproduces more energy than I need at my expense. He also presented battery options to me, but noted that a battery basically doubles the price of the system, while only providing limited back-up power for essential electrical components during an outage. Eric made it clear that purchasing a battery may not be in my best interest given its very high costs. He suggested a better option might be to install a battery at some future time when costs are likely to drop. Costco/Sunrun did not do this. They only tried to sell me a complete system with a battery at double the price. Once Eric and I agreed on an efficient design, the final price was a few thousand dollars less than Costco/Sunrun's quote (excluding the battery). Eric also uses better quality Enphase equipment and installs micro inverters at each series of panels instead of a single micro inverter for all the panels as Sunrun was proposing (a less costly approach for them but not for the consumer).

    So now, per my original intention, it was time to obtain quote No. 3. However, I was so pleased with Eric's professionalism, honesty and integrity, that I decided to speak to three local references of recent NexGen installations. All were very pleased with his work and had only positive things to say about him and his crew.

    Instead of getting a third quote, I called Eric and told him the job was his. The contracting process was seamless with all documents being signed on-line electronically. Once the contract was signed, Eric handled all the City permitting and coordination with SCE.

    After the City permit was issued, NextGen's crew began work and completed the project in two and a half days. They showed up at my home at the agreed upon time each morning and cleaned up the job site each day before leaving. No problems arose during the time they were at my house and there were no change orders or other surprises.

    When the job was done Eric took the time to answer all my questions and also showed me how to use the Enphase app. The app is very user friendly and can be downloaded onto your smart phone, tablet or computer.

    My system has now been operating for two months without any problems.

    If you are considering the installation of a solar system, I highly recommend you give Eric a call. He and NexGen will not let you down.

    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.

  • "Look no further for your solar needs"

    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!
