Stellar Solar Reviews

Reviewers most often describe the sales process as straightforward, low-pressure, and tailored to the home. Complaints are present but relatively limited, and they tend to focus on unprofessional interactions, mismatched expectations, or weak follow-through after the initial sale.Solar.com's composite of published customer feedback, not a customer quote

Low-pressure, tailored proposals. Many reviewers say the sales experience felt honest and not pushy, with proposals that matched site needs and helped set clear expectations upfront. Representative review excerpt: "No upselling, no pressure—just honest advice and a team that clearly knows what they’re doing."

Prepared and straightforward reps. Customers also describe reps as knowledgeable and prepared, with proposals that felt well thought out rather than generic. Representative review excerpt: "He showed up prepared on the first visit with a good proposal of what my home could use based on publicly available Google maps and area comps."

Follow-through concerns. A smaller set of reviews says some sales interactions or early promises did not line up with the later experience, especially when customers needed help after the sale. Representative review excerpt: "But they have yet to even pick up the phone or send someone out to trouble shoot the problem and act like it's not their problem."

Reviewers often say pricing, financing, and rebate handling were explained clearly enough to make the project understandable. At the same time, this category has a meaningful complaint pattern around rate details, refunds, billing responsibility, and timing around rebates or incentives.Solar.com's composite of published customer feedback, not a customer quote

Clear value and proposal framing. Positive reviews say the project economics were presented in a way that made the purchase easier to evaluate, and some customers mention helpful guidance on related project costs. Representative review excerpt: "The process started with Connor Smith who assisted with the sale and offered helpful tips, such as having the roof replaced under the same contract (with Cowboy Roofing), and securing..."

Favorable pricing and savings. Some reviewers report that the system cost and monthly savings lined up with expectations, with bills dropping after installation for those who were satisfied on this front. Representative review excerpt: "The system has been running flawlessly, and my monthly bill has dropped from almost $400 to under $100."

Financing and refund complaints. A subset of customers report confusion over financing terms, delayed refunds, or disputes about billing and rebate timing after the project was underway. Representative review excerpt: "I called the bank who did the pre-approval and they confirmed rates were different and adjusted my tentative loan for the better loan rate."

Communication is a consistent strength in the review set, especially around responsiveness, updates, and keeping projects moving across multiple stages. Still, some reviewers report gaps in follow-up, limited response channels, or unresolved communication when issues came up.Solar.com's composite of published customer feedback, not a customer quote

Responsive, well-coordinated projects. Many reviewers praise steady updates and professional coordination from the first call through completion, including complex projects that required a lot of handoffs. Representative review excerpt: "From my initial phone call with Stellar Solar to final completion just a few days ago, everyone I talked to has been incredibly professional."

Clear updates during the work. Customers also describe being kept in the loop during the project, with teams checking in and communicating clearly about next steps. Representative review excerpt: "The Team showed up when they said they would and keep me and my family in the loop at the close of each day."

When follow-up lagged. Some complaints say communication became harder after problems surfaced, with customers reporting slow callbacks or limited reassurance when they wanted answers. Representative review excerpt: "My system hasn’t worked for a week, I’ve called multiple times, and haven’t had any communication back."

Most reviewers describe permitting, installation, inspection, and activation as orderly and often quicker than expected. A smaller set of comments notes delays, repeat inspections, or extended timelines, but these are usually framed as exceptions rather than the norm.Solar.com's composite of published customer feedback, not a customer quote

Efficient end-to-end timing. Reviewers frequently say the process moved smoothly from contract to permission to operate, with some projects finishing quickly and on schedule. Representative review excerpt: "From the first day of roofing to battery installation, panels, inspection, and formal permission to operate, the entire process took only 3.5 weeks."

On-time coordination. Many customers also mention crews arriving when promised and keeping the project moving day by day, which helped the timeline feel predictable. Representative review excerpt: "The Team showed up when they said they would and keep me and my family in the loop at the close of each day."

Delays and inspection setbacks. A smaller number of reviews describe slower-than-expected permitting or activation, including repeated inspection issues that pushed the project out. Representative review excerpt: "They were scheduled and completed, but did not pass inspection the second time."

Installation quality is one of the strongest themes in the review corpus. Reviewers commonly praise professional crews, careful workmanship, and clean job sites, while complaints are comparatively limited and usually focus on specific repair or restoration issues.Solar.com's composite of published customer feedback, not a customer quote

Professional, efficient crews. Customers often describe installers as respectful, efficient, and ready to work, with strong execution even on more complex setups. Representative review excerpt: "The crew showed up ready to work, were professional, respectful, and incredibly efficient."

Careful, high-quality installs. Many reviewers say the installation itself was clean and well handled, with crews earning praise for workmanship and attention to detail. Representative review excerpt: "Joseph (PV and Battery Lead installer) and Robert installed the Tesla Powerwall 3, Tesla Universal Wall charger and Tesla remote switch."

Occasional site-care misses. A few complaints mention roof or site damage, missing details, or repair crews that did not leave a polished finish after correcting an issue. Representative review excerpt: "The panel installers drove screws through the interior of our new flat roof- when they fixed it (which they did)- they didn't paint the interior of the roof to match..."

This category is very strong overall, with many reviewers reporting solid production, dependable monitoring, and effective help when issues arise after activation. Complaints exist, but they are a minority and mainly concern underperforming equipment, monitoring problems, or slow or costly post-install support.Solar.com's composite of published customer feedback, not a customer quote

Long-term reliability. Reviewers frequently say their systems continue producing well over time, and some mention continued satisfaction years after installation. Representative review excerpt: "It's been 7 years and my @StellarSolar system is still producing power and saving me money every day."

Helpful issue resolution. Several customers report that when a problem did come up, a knowledgeable technician or follow-up fix resolved it successfully. Representative review excerpt: "This consumption issue was nothing that they created, but without hesitation he sent out a very knowledgeable technician and fixed our problem once and for all."

Post-install support concerns. A smaller group reports trouble getting attention for system errors or support needs after the work was completed, including questions about monitoring and service fees. Representative review excerpt: "They install solar systems and then do not provide any help or support without a full service appointment and 250$ fee."
