Altsys Solar Reviews

Reviewers mostly describe the sales process as clear, helpful, and professional, with several saying the team explained system needs and next steps well. The category still shows one complaint about sales expectations not lining up cleanly for every customer, so the overall read is positive-to-mixed rather than fully clean.Solar.com's composite of published customer feedback, not a customer quote

Helpful explanations. Several reviewers say the team took time to explain what the system needed and why, which helped them feel informed during the proposal stage. Representative review excerpt: "Eric was so helpful explaining what we needed in our system and why."

Honest, prompt interactions. Reviewers also describe the staff as honest, helpful, professional, and prompt in their dealings before and after the sale. Representative review excerpt: "Jack and his team at AltSys Solar have always been extremely honest, helpful, professional, and prompt."

Expectations not always aligned. There is at least one complaint suggesting the proposal or follow-through did not match what the customer expected after moving forward. Representative review excerpt: "My only regret; I should’ve listened to my wife and made the move to solar three years ago!"

Feedback on pricing and financing is generally favorable, with reviewers saying bills went down and that the company was worth working with. Still, this category has one complaint pattern, so transparency around final costs, financing details, or timing-related expectations is not uniformly praised.Solar.com's composite of published customer feedback, not a customer quote

Lower bills reported. Some reviewers say their electric bills dropped significantly after going solar, which they connect to a positive value experience. Representative review excerpt: "He walked me through how to do it online and so far my bill is 1/4 of what it was under the old rate!"

Repeat customers stayed positive. A few reviewers mention returning for a second project or recommending the company, suggesting the price experience was acceptable to them over time. Representative review excerpt: "I have had them do 2 solar installation projects for me over the last 10 years and both times they exceeded my expectations."

Value concerns exist. The review set includes one complaint indicating that price, financing, or timing-related expectations did not feel clear to every customer. Representative review excerpt: "We did our homework and going local is a great choice."

Reviewers commonly report strong communication, with updates, billing help, and support through setup coming up often. The category also contains several complaints about missed calls, delays, and paperwork coordination, so responsiveness appears helpful for many customers but inconsistent for others.Solar.com's composite of published customer feedback, not a customer quote

Frequent updates. Reviewers say the company kept them updated through the process and answered questions along the way. Representative review excerpt: "Throughout the process Eric was in constant communication with updates."

Help with billing and setup. Some customers describe hands-on help with billing and utility setup after installation, which they viewed as good coordination. Representative review excerpt: "My husband and I also had a fantastic experience with Yolanda who helped us with billing, as well as Bryan when it came to our electrical needs."

Coordination breakdowns reported. Complaints in this category mention missed calls, delayed responses, and paperwork or post-work issues with the utility side of the project. Representative review excerpt: "Called 6 times to get a quote and no one picked up their phone."

Timeline feedback is mostly positive, with several reviewers saying appointments were scheduled quickly and installations moved smoothly. However, a smaller set of complaints describes delays in activation or scheduling, so reliability appears solid in many cases but not consistent across the full review set.Solar.com's composite of published customer feedback, not a customer quote

Quick scheduling. Some reviewers say appointments were set quickly and the project got moving right away after the initial contact. Representative review excerpt: "I received a call from Eric, scheduled an appointment right away to go over options."

Delay and activation issues. Complaints mention prolonged waits for utility-related steps or a lack of timely notice when delays came up. Representative review excerpt: "They messed up our post work to pg&e and have robbed us of solar for 4 months."

Workmanship is one of the stronger areas in the review set.

Post-install feedback trends positive overall, with many reviewers saying the company helped with commissioning, monitoring questions, and follow-through after the system was turned on. There are a few complaints about utility paperwork and delayed activation affecting performance, but they are outweighed by positive reports of support and system results.Solar.com's composite of published customer feedback, not a customer quote

Post-install follow-through. Reviewers say the team helped with utility setup and answered questions about how to use the battery effectively after installation. Representative review excerpt: "After the solar was installed they did all the hard work in getting it set up with Edison and have answered my questions regarding how to effectively use the battery."

Representative review excerpt: "Ben was able to assist me greatly as well as Eric and after a whole year of wasted time these guys were able to commission my battery for my solar..."

Paperwork and activation complaints. A few reviewers report that utility paperwork or activation steps were not completed as expected, which affected how soon their systems delivered value. Representative review excerpt: "Even after a conversation with PG&E, which led to us finding out that Eric Sustaita has not even processed out paperwork with PG&E."
