Solar Installation Group Reviews

Reviewers mostly describe the sales process as clear, knowledgeable, and low-pressure. A small number of complaints mention proposal sizing, pressure, or expectations that did not match the final outcome, so the pattern is positive overall but not flawless.Solar.com's composite of published customer feedback, not a customer quote

Clear, patient sales support. Many reviewers say the sales team explained the system in detail and helped them feel comfortable moving forward. They often describe the process as honest and not pushy. Representative review excerpt: "My local sales person Jennifer, was very knowledgeable, completely honest and patient with my decision process."

Helpful system explanations. Several reviews say the proposal process covered benefits, equipment choices, and expected savings in a way that made the project easier to understand. These accounts portray the sales stage as informative and organized. Representative review excerpt: "It was Deanna Greener's visit and extensive explanation of the system's benefits from start to finish that convinced us to go solar."

Sizing and expectation issues. A smaller group of reviewers reports concerns about panel counts, contract expectations, or feeling pressured into signing. These complaints are present but limited relative to the positive feedback. Representative review excerpt: "Because on initial visit they underestimated how many panels we need to accommodate our usage even after reviewing our pge bills for 1 year."

Feedback on pricing and financing is mixed and sits near the middle of the pack. Some reviewers report honest pricing and contract terms being followed, while others mention surprise charges, unclear cost details, or disagreements about repair and financing-related expenses.Solar.com's composite of published customer feedback, not a customer quote

Honest pricing in some projects. Several reviewers say the pricing was explained clearly and the contract terms were honored. These accounts describe the financial side of the project as straightforward from the customer’s perspective. Representative review excerpt: "Every promise of their contract has been abided by."

Unexpected cost concerns. Other reviewers report surprise charges or concerns about repair costs, and some say they did not receive enough detail on materials or total pricing. This category shows more complaints than the stronger service areas. Representative review excerpt: "I called them to repair it, and they want to charge me $750."

Financing and out-of-pocket clarity. Some customers describe financing as working smoothly or resulting in no out-of-pocket cost, but others still raise questions about what was included and when costs changed. The overall pattern is mixed rather than consistently positive.

Reviewers generally describe strong communication during the sales and project phases, with staff explaining steps and staying engaged. The complaint pattern is centered on delayed responses, missed callbacks, and cases where customers say they had to keep reaching out to get help.Solar.com's composite of published customer feedback, not a customer quote

Helpful explanations and updates. Many reviewers say representatives explained the process clearly and stayed in touch through the project. They often describe the coordination as organized and customer-focused. Representative review excerpt: "Our Representative Damian Fernandez sat down with us and explained in detail all the benefits and services they had to offer."

Responsive team members. Several reviews praise specific staff for detailed explanations and consistent communication. These accounts suggest that, when communication goes well, customers feel guided through the process. Representative review excerpt: "Josh Clark took the time to explain things in great detail and worked diligently to get us up and running."

Callback and follow-up gaps. A smaller but meaningful set of reviewers reports difficulty getting responses, with missed calls or long delays before anyone resolved the issue. The main concern here is follow-through after the initial sale or install. Representative review excerpt: "Then they disappear, never return any calls, and everytime you do talk to someone they promise to fix the problems then ghost you again."

Most reviewers say the project stayed on schedule or moved efficiently through installation and inspection. The main complaints involve delays, shifting completion dates, or slow progress when permits or activation steps took longer than expected.Solar.com's composite of published customer feedback, not a customer quote

Fast install and inspection. Some reviewers report that installation was completed quickly and inspections followed soon after. These reviews describe a smooth path from installation to activation. Representative review excerpt: "The job was done in one day and PG&E inspection completed the next day."

Permits and project steps handled. Several customers say the company managed permits and related coordination as part of the project. This suggests the timeline was often structured and handled with active project management. Representative review excerpt: "SIG took care of permits, arranged financing and provided excellent referrals for the roof install (True Roof) and tree trimming (Sindelar Tree Service)."

Delay watch-out. A few reviewers describe delays or dates that kept moving, especially when waiting for final steps. Representative review excerpt: "It was a big let down the be told in May this would be done in August but here we are in September now being told it will have to..."

This is one of the stronger areas in the review corpus. Reviewers frequently describe the crews as professional, efficient, and careful, while only a very small number mention workmanship or follow-through problems.Solar.com's composite of published customer feedback, not a customer quote

Professional installation crews. Many reviewers say the installers were fast, knowledgeable, and professional on site. These accounts suggest solid day-of-install execution and courteous crew behavior. Representative review excerpt: "The Crew of gentlemen that installed were fast, efficient and knowledgeable."

Good site communication. Some customers say they were kept informed throughout installation and that questions were answered promptly. That points to a smooth on-site experience for many projects. Representative review excerpt: "Throughout the installation process, she kept in constant contact with me and was always available to answer any questions I had."

Isolated workmanship complaints. A few reviewers report poor workmanship or unresolved issues after the install. These complaints appear, but they are rare relative to the volume of positive installation feedback. Representative review excerpt: "They used poor workmanship when they installed it."

Long-term support is a weaker part of the review picture. Some reviewers report successful repairs and good system output, but a sizable complaint pattern says follow-up was slow, warranty support was difficult to obtain, or performance issues required repeated customer outreach.Solar.com's composite of published customer feedback, not a customer quote

Successful repair visits. Some reviewers say service visits resolved inverter or system problems and got the system running again. These reviews show that post-install support can work well when a technician engages the issue directly. Representative review excerpt: "So, super friendly and knowledgeable, Brian came out .He replaced the faulty inverter and had our system up and running in no time."

System output and savings reports. Several customers report that their systems are producing well and generating monthly savings. These positive comments indicate that some owners are satisfied with how the system performs after turn-on. Representative review excerpt: "We are now saving money every month, and feeling good about doing our part to reduce energy consumption."

Post-install support concerns. Other reviewers say they had to make repeated calls or contact manufacturers themselves to get problems addressed. The strongest negative pattern in this category is slow warranty and service follow-through after activation. Representative review excerpt: "Because SIG solar failed to provide support, WE had to contact the inverter manufacturer, twice in the past few years to get the system functioning, something the installer should have..."
