AltSys Solar consistently delivers competent installations but has a documented gap in utility paperwork handling. We found two customers who went months without solar benefits because required forms sat unprocessed with their utility company, and both describe being ignored when they reached out for help. That's a serious lapse for a local installer that otherwise earns steady praise for workmanship and customer service. The positive side is real, though. One reviewer watched Jack Ramsey, the owner, write a $4,000 check to compensate for a utility delay that wasn't even AltSys's fault. Another got a follow-up call years after installation to walk through an Edison rate change that cut their bill by 75%. Twenty-three reviewers specifically praised the installation quality, and we couldn't find a single complaint about panels failing or inverters breaking down. If you value post-sale handholding and want a team that won't vanish after the install, AltSys checks those boxes. But if your permit or utility interconnection hits a snag, you may end up chasing them for answers.
If you're comfortable triple-checking permit and utility paperwork yourself, AltSys delivers solid hardware and above-average follow-up. But if you need an installer to own the entire process from contract to final approval, the communication gaps are a real risk.
T Ellsworth first had AltSys Solar install a system on their residence several years ago, and that array has run flawlessly. Later, with a business partner, they decided to install solar for their farm LLC, requested bids from several companies, and chose AltSys. The farm installation began in early 2020, just before the COVID-19 pandemic created permitting and utility slowdowns. PGE dragged on approval of the finished system, and Jack Ramsey, AltSys’s owner, stepped in and wrote a $4,000 check to the LLC to compensate for the delay even though the hold-up wasn’t AltSys’s fault. The owner’s personal gesture and the company’s hands-on customer service left them convinced of AltSys’s ethical standards. The detail that sticks is simple and concrete: the owner personally cut a $4,000 check to make the customer whole while waiting on the utility.
After a rooftop solar system was installed four months ago, Kings Dairy expected lower electric bills but discovered the opposite — their charges have actually doubled and they’ve seen no financial benefit. They learned, after speaking with PG&E, that an employee named Eric Sustaita never processed the required paperwork with the utility, so the system wasn’t properly hooked into their account. Attempts to get answers from the installer went unanswered for weeks, leaving them with higher bills, unfiled PG&E paperwork, and no resolution. The lasting image: a completed installation that never translated into savings because the necessary utility paperwork wasn’t submitted and the company stopped communicating.
Brian chose AltSys Solar for a home solar installation and found the whole process refreshingly straightforward: pricing arrived upfront with no hidden fees, and the team led by Jack handled the job professionally and with extra care. He came to see them less as a typical contractor and more as local energy advisors — an impression cemented when the owner phoned after the install to ask if he’d compared rates with SCE, then walked him through the online comparison. That follow-up translated into real savings: his bill now runs at about a quarter of what it was under the old rate. What stuck with him most was the owner’s personal outreach and practical help — old‑school ethics applied to a high‑tech service.

Brock Bonner was weighing a rooftop solar installation for his home and discovered Alt Sys Solar stood out for one reason above all: they explained financing clearly and thoroughly. Eric dropped by the house several times to walk through options and answer questions, which steadily built Brock’s confidence in moving forward. After signing the contract, Alt Sys handled the permit work with the city and county—removing the usual headache of bureaucracy. Eric kept him updated throughout the process, and Brock never once had to chase the team for information or paperwork. A year in, he found that every promise, agreement, and schedule had been honored; the staff remained friendly and accommodating throughout. What stuck with him most was the steady communication and the fact that someone else was managing the messy details, so he could relax about the investment.

After comparing local companies and hearing several recommendations from neighbors, Amber Avila chose AltSys Solar. She worked with sales rep Ricardo Armendariz, who proved responsive, knowledgeable and genuinely easy to deal with. A year after installing solar panels and a battery, she discovered that the old $900 electric bills were a thing of the past — this summer her bill never exceeded $16. She phoned support a couple of times for minor questions, and each time a friendly representative answered and resolved the issue quickly. What stood out most was the combination of attentive service from sales through support and what she considered a fair price for a reliable system. The detail she keeps coming back to is simple and concrete: her summer bill never went above $16.
Lucky chose Jack and his crew to install a home solar system, and three years later the array has performed with not a single problem. They experienced true start-to-finish service — the team handled everything from the initial steps through installation and follow-up, a genuinely cradle-to-grave approach. The most memorable part of the project was Jack’s ongoing availability; knowing he would be there to answer any question gave them confidence long after the panels went live. In the end they ended up with a dependable, low-maintenance system and the reassurance that support is only a phone call away.
After shopping several installers, Frank chose AltSys Solar for his home and was most impressed that the crew didn’t just mount panels — they took time to understand his household energy use and taught him how to get the most from the system. He found the team friendly and refreshingly no-pressure, walking through operation and tips so he felt confident managing the array. The installation moved quickly, and the system was active in about five days. He now regrets not making the switch when his wife first suggested it three years earlier. The detail that stuck with him: hands-on instruction plus a five-day turnaround that had his home generating power almost immediately.
Randy turned to Alts Solar for a system on his home and discovered he hasn't received an electric bill since the panels went live. He ended up with an array that produces roughly $1,000 more in electricity each year than he uses, so the system actually generates a small annual surplus. The installation process felt seamless to him — Alts guided him through every step and helped whenever he needed it. The detail that sticks: no monthly bill since activation and about $1,000 a year in excess generation.
Nola Lack has had a home solar system in place for two years and experienced no problems. She found Altsys Solar’s customer service especially helpful: the team guided her through getting the online monitoring set up so the household can watch production and patiently answered any questions. They accommodated her extremely picky husband on panel placement and how many to install, adjusted the plan to suit his preferences, and he ended up very happy with the finished system. The detail that stood out was that Altsys combined practical help with the monitoring setup and genuine flexibility on layout—two years on, the system runs smoothly and the couple is pleased with the result.
Tyler Coday shopped several installers and discovered AltSys Solar not only offered the best price on a system for his home but also the smoothest process. Eric came out, walked through every detail and answered his many questions, which left the installation essentially pain-free on his side. The crew even installed new smoke detectors so the project could pass inspection, and they handled all the paperwork and technical handoffs with Edison after the panels went up. They stayed communicative through the whole timeline, showed him how to get the most from the battery, and continue to monitor the system remotely. When his Wi‑Fi dropped, AltSys checked in because they could see the system status — a small but telling service touch. He ended up with a working solar-plus-battery setup and ongoing support that carried well beyond the install.
Ashley worked with Eric and the Altsys team to outfit her home with a 13 kW solar system and two batteries. The whole process moved quickly — the system was installed in under 45 days from contract signing. She watched her electric bill plunge from $465 in February 2024 to $112 in February 2025, and this month’s projection sits at only $83. The detail that sticks: a sub-45-day turnaround combined with an immediate, measurable cut in winter electricity costs — roughly a 76% drop in that comparison month.
