Kuubix (CLOSED) reviews

The Verdict
Kuubix went out of business, and the reviews show why. We found a company where installations often went smoothly but post-sale support collapsed. One homeowner sat with panels on their roof for seven months waiting for a main panel upgrade, cycling through three different project managers as staff left the company. Another paid for a system in December 2020 that still wasn't operational by March 2022, with their sales rep acting surprised each time they called for updates. The workmanship numbers tell a split story: 24 reviews praised the physical install quality, but 14 described failures severe enough that some owners hired lawyers or demanded panel removal. Communication breakdowns were systematic. Permission-to-operate delays stretched two months because the utility flagged incorrect paperwork that Kuubix never saw. When roofs leaked post-install, callbacks went unanswered for weeks. The company charged homeowners through their lenders even when systems sat dark and useless.
This company is closed. If you're researching them because you have an existing system they installed, expect zero manufacturer support and plan to hire an independent solar service company for repairs or monitoring issues.
Reviews That Shaped Our Verdict
cj hired the company to install a residential solar array that was supposed to be finished in three days, but the job stretched out until the system finally came online six months later. They watched crews mount the panels, then remove and reinstall them twice after the initial install. The company handed over no operating instructions, forcing them to spend several days emailing and dealing with the installer's lawyer before having to bring in their own attorney to get the work completed. After activation a roof leak developed where the crews had worked, and calls went unanswered—voicemail promised a callback within 48 hours, yet a week passed with no return contact. The clearest takeaway: a quick, three-day install turned into a months-long, lawyer-driven ordeal that left them with a leaking roof and no proper handover.
After signing a contract in January 2022 and watching crews mount panels on March 10, 2022, kcialino discovered seven months later that the system still wasn’t functioning and there was no estimate for when the promised main electrical panel upgrade would be completed. They expected the panel upgrade to stretch the timeline a bit, but didn’t expect the project to stall indefinitely. Over that period they dealt with three different project managers—two of whom left the company—and faced almost no proactive communication from Kuubix. Updates only arrived when they phoned; every interaction felt like the company was hearing about the problem for the first time. Patient but frustrated, they could not reconcile having paid for panels that sit on the roof without delivering any benefit. The lasting image: paid-for equipment installed months earlier but idle, with no clear finish date—something a buyer should weigh against any low price.
Tadd shopped around for a solar installer and followed a friend’s recommendation to contact Kuubix. He ended up most impressed by the crews’ kindness: they came to map his roof in mid‑January with Christmas lights still up, and when he asked them to unhook one section they climbed up and removed every strand — a small gesture that set the tone for the project. Kitch listened to his concerns, helped design a system that fit the house and usage, and kept checking in after the install. The installation itself went smoothly and quickly. He asked that the electrical boxes be tucked behind a fence and kept out of public view; the tubing was routed neatly and as hidden as possible, and the panels were mounted exactly to permit specs, flush and unobtrusive. A technician arrived early on inspection day and worked through the morning until the city inspector showed up, even paint‑matching the exterior tubing — an unexpected finish that left him very happy with the workmanship. The main snag came after the hardware was in place: Kuubix’s office handling PTO (permission to operate) didn’t communicate well with the utility. What was presented as a quick final step stretched out — the system

What You Can Expect
Kd48281 watched Virgil’s crew mount solar panels on their roof in December 2020, and by March they discovered the array still hadn’t been connected to power. No project manager ever showed up, Virgil stopped following up after the install, and the homeowner ended up making all the calls — only to be met with surprise each time when they said the system wasn’t activated. They then found out the company no longer had an electrician in their area, and the lender insisted payments would begin regardless of whether the panels were operational. Concluding the installer had rushed the physical installation without arranging activation, they decided to have the panels removed and hire a different company. The detail that sticks: the panels went up fast, but the work needed to make them actually produce electricity never happened, and payments were expected even for a nonworking system.

Ashely.jae hired Kuubix for a residential solar setup and ran into problems early: the equipment never operated correctly. She waited while the company worked on fixes, and the issue wasn't finally corrected until the end of the year. At that point PG&E delivered a $1,500 bill, and Kuubix refused to pay or take responsibility even though she had paid for a solar service package. She ended up covering the charge herself, and no one from Kuubix reached out after the sale. The detail that sticks is simple and stark: the system’s long-running failures led to a $1,500 utility bill that the installer wouldn’t address, and she was left footing the cost.
