Sales & proposal integrity
Sales Integrity7.2/10
Reviewers describe the sales and proposal process as clear, collaborative, and aligned with expectations. The available evidence is entirely positive, with comments focused on system design, panel placement, and a low-pressure handoff from planning into installation.Solar.com's composite of published customer feedback, not a customer quote
Clear system design. Reviewers say the proposed systems were designed to match their needs, including difficult roof layouts and higher production goals. Several describe the final design as meeting or exceeding expectations. Representative review excerpt: "Perfect job from start to finish -- system design was for a difficult roof, but worked out great and is producing slightly more than predicted."
Collaborative planning. Reviewers report being able to work through layout decisions collaboratively, which helped improve the final panel placement. This theme suggests a proposal process that left room for customer input. Representative review excerpt: "We collaborated on panel placement, which I liked because we got a better array position than either of us had initially planned."
Single-team experience. Some reviewers appreciated not having to repeat details across multiple handoffs between sales and field teams. That continuity appears to have made expectations easier to manage. Representative review excerpt: "This was important because I did not have to or want to deal with the salesman, then the office manager, then the installation crew etc etc."
Price & financing transparency
Price Transparency6.7/10
Reviewers mostly describe pricing as favorable and often below what they expected. There is also some friction around billing and incentive timing, including a mixed report tied to a delayed refund and a negative report about an unexpected invoice.Solar.com's composite of published customer feedback, not a customer quote
Prices often came in low. Price praise is the dominant pattern in this category. Representative review excerpt: "I got everything I wanted for a price that was under what I'd expected it to cost."
Billing confusion watch-out. One reviewer reported surprise around receiving a bill and described difficulty resolving it. This is the clearest complaint in the category and points to a need for stronger upfront billing clarity. Representative review excerpt: "I finally gave in, even after not knowing they were going to be sending me a bill, and tried to pay the invoice just so they would stop harassing my..."
Incentive timing required follow-up. A mixed review says a rebate-related refund took time to arrive and required persistent follow-up. The delay was attributed to the utility side, but it still affected the customer experience. Representative review excerpt: "While there were delays in receiving our SGIP refund (due to PGE, not Day One), Megan worked with us relentlessly to shake it loose from PGE beaucracy."
Communication & coordination
Communication7.5/10
Reviewers overwhelmingly describe strong communication, prompt responses, and good follow-through across projects and service calls. The evidence includes a small number of negative reports, but those are rare relative to the broader praise for coordination and support.Solar.com's composite of published customer feedback, not a customer quote
Responsive project updates. Reviewers say they were kept informed throughout the project and felt the team communicated clearly from start to finish. This is one of the strongest themes in the feedback. Representative review excerpt: "From start to finish, their communication was excellent, and they kept us informed throughout the entire project."
Helpful post-install support. Several reviewers report that the company responded promptly when issues came up after installation, and that staff were knowledgeable and helpful in resolving them. That pattern extends beyond the original install into service support. Representative review excerpt: "We had a few issues the last two years and Day One Solar responded in a prompt and efficient manner Megan in particular is incredibly knowledgeable, very helpful and responds..."
Rare service complaint. One reviewer described a system not responding after a home purchase, which stands out as the main negative note in this category. It appears to be an isolated complaint rather than the dominant pattern. Representative review excerpt: "I purchased a home with a solid system installed by this company, and the solar system not responding or working."
Timeline reliability
Timeline Reliability7.1/10
Reviewers generally describe schedule management as dependable, with projects often moving from contract to completion on a reasonable timeline. A few comments note delays around inspection scheduling or incentive processing, but those reports are limited and mostly framed as situational.Solar.com's composite of published customer feedback, not a customer quote
Projects often stayed on track. Reviewers say projects moved steadily from first contact to completion, even when the timeline included travel, vacations, or coordination with other contractors. The overall pattern is one of solid schedule management. Representative review excerpt: "From first contact to completion of project was less than three months (and this included delays due to summer travel and vacations) and it took just one month from contract..."
Coordination around other work. Some reviewers describe the team successfully coordinating around roof work and other contractors without derailing the job. That suggests good flexibility when schedules were more complex than usual. Representative review excerpt: "We had a lot of roof work being done at the same time as the solar installation - 3 different contractors besides Day One and they were able to work..."
Occasional timing delays. A mixed review mentions a delayed rebate-related refund and a longer wait for inspection scheduling during mid-COVID conditions. The delay is presented as context-driven, but it still affected the timing experience. Representative review excerpt: "While there were delays in receiving our SGIP refund (due to PGE, not Day One), Megan worked with us relentlessly to shake it loose from PGE beaucracy."
Workmanship & site care
Workmanship7.8/10
Reviewers mostly describe the crews as professional, careful, and willing to solve unusual installation problems. Cleanup and site disruption are not common concerns in the feedback, though there is one strong complaint about an incomplete install.Solar.com's composite of published customer feedback, not a customer quote
Professional install crews. Reviewers say the installation teams handled unusual site conditions quickly and professionally. Several comments point to careful workmanship and a willingness to do the job the right way. Representative review excerpt: "There were lots of unusual things with my install, and they breezed through it quickly and professionally."
Problem-solving on site. Reviewers report that the team persisted through troubleshooting until they identified a solution that fixed the issue. This reflects strong hands-on workmanship when complications arose. Representative review excerpt: "The Day One Solar team worked persistently to identify the problem, finally making the ultimately correct decision to pull new wire from the main panel to the inverter, which solved..."
Isolated quality complaint. One reviewer described an incomplete installation and follow-up charges to finish the work. This is the main workmanship complaint in the available review set. Representative review excerpt: "They charged the owner thousands and thousands of dollars to do an incomplete install that was recommended by the manufacturer just to come out later and charge the home owner..."
Long-term support & performance
Long-Term Support7.8/10
Reviewers report strong post-install support, with many comments about prompt troubleshooting, monitoring, and repair follow-through. Most feedback is positive, though there are a couple of complaints tied to inverter issues and periods of lost generation.Solar.com's composite of published customer feedback, not a customer quote
Prompt troubleshooting support. Reviewers say the company was knowledgeable and effective when diagnosing and fixing system issues after install. Support appears to continue well beyond the original project closeout. Representative review excerpt: "One of my solar panels wasn't functioning, and even though they didn't install the system they were very knowledgeable and prompt and effective in isolating the issue and fixing it."
Persistent repair follow-through. Some reviewers describe the team working through difficult post-install problems until the system was working again. That persistence is a recurring part of the post-install feedback. Representative review excerpt: "The Day One Solar team worked persistently to identify the problem, finally making the ultimately correct decision to pull new wire from the main panel to the inverter, which solved..."
Service gaps can matter. A negative review describes an inverter failure that led to months of lost generation, which is the clearest long-term performance complaint in the set. It shows that equipment issues can have a meaningful impact when they arise. Representative review excerpt: "Our inverter died during the height of Covid and we lost 6 months of generation since well… in 2020 there were plenty of other things to worry about."
