We’ve been enjoying home solar power with Nextdoor Home Upgrades for one year now, and the experience has been fantastic from start to finish. The initial setup was easy and affordable, and we’ve seen consistently low electricity bills ever since. One of the highlights was when our neighborhood lost power—our backup solar power kicked in right away, preventing any issues with our refrigerator.A special shout-out to Josh, who has been professional, knowledgeable, and trustworthy throughout the process. He followed up with us after a year to ensure our system was performing as promised, and even made an adjustment to help us save even more money. We’re very happy with both the product and the service from Nextdoor Home Upgrades!
We had such a great experience with Next Door Solar! We initially spoke with Sam, who was friendly, knowledgeable and straight up with us about costs, financing, solar plans and next steps. Finding someone honest and trustworthy was huge! Our experience through the solar process was pretty seamless too. The next door solar crew was professional and got their work done quickly, efficiently and left no mess behind. The biggest variable was city inspections, but those all went smoothly and the next door solar team kept us in the loop each step of the way. I highly recommend working with them! If you want honest, professional, high quality work and service - look no further.
I had an amazing experience going solar with Next Door. Josh was easy to communicate with via text from start to finish, and answered all of my questions thoroughly. The workmanship on the install and the attention to detail was excellent – they installed some black trim below the street-facing solar panels that makes the install look finished, and they even asked for my house paint to paint the conduit so that it matched perfectly. This is a local company that doesn't subcontract out their work, unlike some of the larger installers, and it is well worth the slightly higher price (though their price was still very reasonable relative to other quotes we got). I would recommend this company without hesitation!
Next Door Home Upgrades is the dream team of solar. They made the solar process a breeze with constant communication and clear expectations. Johnny at NDHU is friendly, knowledgeable and trustworthy with your solar needs. He sized our system perfectly with 20 panels and two Tesla PW3 batteries and plenty of room to grow if our demands increase. After researching solar and seeing the horror stories about Tesla installation taking forever and customer service nonexistence, Johnny was able to provide the local installation and top tier customer service while still installing the Tesla equipment we wanted. The whole process took less than 2 months (closer to one month) from start to finish and the install team at NDHU was fantastic. Started process on 8/19/25, installed on 9/11/25, city approval 9/15/25, pending SCE PTO. We had 3 quotes (Tesla, NDHU, other) which all were similar in cost, but NDHU is the way to go with their top-notch customer service and knowledgeable electrician/installers. If I had to do it all over again, I would not have changed a thing. If you want solar done the right way the first time, Next-Door Home Upgrades is where to go.
“ I dare you to compare” with other Solar companies! Anyone can sell Solar systems , but is it the right system for your needs. Next Door Solar and Johnny Rhee provided the expertise and a custom system that was required for my main house and ADU at a competitive price. Expert installers provided a clean and professional installation. Constant communication with me and the power company made the install seamless! Great Job!Thank you!!
