Sales & proposal integrity
Sales Integrity7.3/10
Reviewers generally describe the sales experience as clear, helpful, and low-pressure. The most common praise centers on staff explaining the process, answering questions, and setting expectations in a way that helped customers feel comfortable. A small number of complaints mention less experienced or less effective sales interactions.Solar.com's composite of published customer feedback, not a customer quote
Clear, low-pressure guidance. Reviewers say the sales process was informative and not pushy, with staff taking time to explain options and answer questions. Several customers describe feeling that the proposal matched their needs and budget concerns. Representative review excerpt: "Bottom line: Contact these folks if you're looking for someone who isn't going to pressure you into buying something more than than you need, who is extremely knowledgeable, and is..."
Helpful support through the process. Reviewers also report that staff stayed involved and provided guidance through next steps, which helped reduce uncertainty. The tone in these accounts is consistently professional and reassuring. Representative review excerpt: "Claryssa was with me every step of the way, providing guidance and reaching out to agencies on our behalf - her friendly and professional presence did a lot to calm..."
Watch-out: isolated sales concerns. A small number of reviewers describe a less reassuring sales interaction, including concerns about representative experience. This appears to be a limited complaint pattern rather than the dominant view. Representative review excerpt: "Tenco sent out a sales representative around 19 years old, who had been working for the company for about a week."
Price & financing transparency
Price Transparency6.5/10
Reviews on price and financing are mostly positive, but this category is more mixed than the others. Positive feedback focuses on staff explaining price points and options, while complaints mention confusion or dissatisfaction around billing-related details. The review set suggests that transparency is often good, though not consistent enough to avoid occasional disputes.Solar.com's composite of published customer feedback, not a customer quote
Options explained clearly. Some reviewers say the company walked through different price points and options before work moved forward. These customers describe the process as helpful and easy to understand. Representative review excerpt: "I spoke to Matt Mitera, who I believe is the ower, about my option and after different price points and options, I decided to do a bypass and opt for..."
Willingness to work with customers. Other reviewers report that staff listened and worked with them on the solution they chose. These accounts frame pricing discussions as collaborative rather than confusing. Representative review excerpt: "He is very willing to work with the customer and most important LISTENS, I only wish all the contractors I deal with in the valley were as professional as TencoSolar!."
Watch-out: billing and cost confusion. A small set of complaints mentions disputes or confusion tied to payment details and cost-related communication. The pattern is limited, but it is the main reason this category lands below the stronger operational scores. Representative review excerpt: "Dan McIntyre, (who claims to be the owner) said via text (I'll attach pictures if this review gets flagged or hidden, attached pics on another review site) "you probably entered..."
Communication & coordination
Communication7.4/10
Most reviewers describe communication as responsive, organized, and supportive. They frequently mention timely updates, coordination across office and field teams, and staff helping move projects forward or resolve issues. Complaints are present, but they are comparatively rare in the review set.Solar.com's composite of published customer feedback, not a customer quote
Responsive and organized coordination. Reviewers say the office and field teams stayed coordinated and kept them informed throughout the process. Several describe the experience as efficient and reassuring. Representative review excerpt: "Their communication and coordination is excellent throughout the process."
Hands-on customer support. Customers also report receiving direct guidance from staff who helped with follow-up steps and agency communication. These reviews emphasize patience and personal attention. Representative review excerpt: "Claryssa was with me every step of the way, providing guidance and reaching out to agencies on our behalf - her friendly and professional presence did a lot to calm..."
Watch-out: occasional follow-up issues. A few reviewers mention delays in callbacks, follow-up, or scheduling. These complaints suggest that communication is usually strong, but not uniform across every interaction. Representative review excerpt: "Needless to say, Tenco did not even bother to call as a follow up for their own sales reps' visit."
Timeline reliability
Timeline Reliability7.1/10
Timeline feedback is mostly favorable, with reviewers often saying work was completed quickly or on time. Several also describe the company as effective at handling process steps tied to utility or building-safety coordination. Still, a small number of complaints point to scheduling delays or interruptions during installation visits.Solar.com's composite of published customer feedback, not a customer quote
Often on time and efficient. Reviewers say appointments were handled on time and jobs were finished quickly. These comments suggest solid day-to-day schedule reliability in many cases. Representative review excerpt: "Smart, honest and competent response to my request for assistance --and on time!"
Handled utility and permitting steps. Some customers describe the company as helpful when the project needed coordination with utility or building departments. Those reviews frame the process as manageable and well supported. Representative review excerpt: "We ran into a glitch with our already installed electrical panel that required a somewhat involved process with our utility and Building and Safety (this was my fault)."
Watch-out: scheduling delays can happen. A small number of reviewers mention waiting to get on the schedule or having an install visit interrupted by missing materials. This points to occasional timing friction rather than a broad pattern. Representative review excerpt: "Luis came back to install it but couldn't finish because he didn't have a neutral wire and he needed to get to another job."
Workmanship & site care
Workmanship7.7/10
Workmanship reviews are strongly positive overall, with many customers praising knowledgeable crews, careful work, and clear explanations on site. Reviewers also mention efficient removals, professional behavior, and good cleanup or protection around the job. The few complaints focus on missed issues or roof-related problems that required follow-up.Solar.com's composite of published customer feedback, not a customer quote
Knowledgeable, professional crews. Reviewers frequently describe technicians as skilled, easy to work with, and good at explaining the work. These comments suggest a generally strong installation experience. Representative review excerpt: "Hector was outstanding he and his apprentice was such an enjoyment working with they are so knowledgeable and explained things so easily where I understood it."
Careful, efficient on-site work. Customers also report crews arriving early, completing work efficiently, and protecting the property during the job. That combination of speed and site care comes through repeatedly in the praise. Representative review excerpt: "Orbitz and Randy arrived early for our appointment, surveyed the job to remove solar water panels from the 2nd story of my house and efficiently removed them while sealing off..."
Watch-out: a few site-related complaints. A small number of reviewers mention roof- or junction-box-related problems that they felt were not fully addressed on the first pass. The complaint pattern exists, but it is limited relative to the larger volume of positive workmanship feedback. Representative review excerpt: "The problem was in the junction box on the roof, which Tenco did not even check."
Long-term support & performance
Long-Term Support7.7/10
Long-term support and post-install performance are rated positively by most reviewers. Customers often describe help with troubleshooting, monitoring, and getting systems back into working order, including after installation or commissioning issues. A few complaints note unresolved equipment problems or service gaps, but they are not the dominant theme.Solar.com's composite of published customer feedback, not a customer quote
Helpful troubleshooting after install. Reviewers say staff were patient in helping them understand system status and next steps after installation. These accounts suggest strong support when customers needed post-install guidance. Representative review excerpt: "They were very patient and helped me o understand that my system was not commissioned."
Quick help with monitoring and inverter issues. Customers also report fast problem-solving when inverter or app issues came up. Several describe the company as effective at diagnosing and restoring system performance. Representative review excerpt: "He quickly assessed the problem with my inverter and ensured the app was working on my cell."
Watch-out: some unresolved repair concerns. A small number of reviewers mention ongoing error codes or issues they felt were not fully checked during service. This indicates that post-install support is usually strong, but not flawless. Representative review excerpt: "Our inverter started putting out error codes so I researched based on star ratings and review comments to find a company that could repair or replace the unit."
