Tier Drop Solar reviews

Katrin S had eight solar panels put on her ranch-style roof three years ago and returned in April to add seven more. She found the price competitive with the larger companies she checked, but it was the hands-on service from Randy and his crew that convinced her to hire them again. The installation went smoothly, and she especially appreciated that the electrician took the initiative to remove an old dish antenna while already on the roof — a small, practical touch that made the whole job feel more complete.

Delete had Tier Drop Solar install panels on their house a year ago. When they received the SDG&E true-up, they discovered their annual bill was only $15 — surprising given the whole household has been working and schooling from home since COVID began in March, with the AC running more than expected and the pool pump running all day. They credit Tier Drop’s careful approach: the crew was the only one out of four companies that actually climbed onto the roof to plan panel placement, and the company’s panel-count estimate proved perfect. That on-roof assessment and precise sizing turned into a system that handled the increased at-home load, producing an almost negligible true-up. The detail that sticks: the roof visit and accurate number of panels made a measurable difference — $15 for the year.

After comparing several quotes and doing her homework, Monica C. chose Tier Drop Solar as her top pick. She ended up with a system that eliminated her Edison bill and, a little over a year later, she’s already paid off the panels. The moment that set the experience apart came when Randy and Andrew showed up at her house and climbed onto the roof to take exact measurements—no relying on satellite images—then came back to walk her through the options and the technology. They offered a strong price for what she considers the best panels, ran a fast, tidy installation, and left the system up and running in short order. The crew stayed honest and straightforward throughout, and Monica still has them on speed dial for monitoring, the phone app, or cleaning. What she keeps telling people: they did the hands-on measuring and stayed reachable afterward—those two things made the difference.

Fay M. had solar panels installed on her home a year and a half ago and discovered that her total electric bill for the entire last year came to just $23.16. She walked through a summer with the air conditioning on constantly and then opened a bill showing a $10 balance — essentially a credit she didn’t even need to pay. She can’t imagine continuing to pay $200+ a month for power when the sun covers it. Randy led the job and brought steady knowledge and confidence, and the Tier Drop crew used high-quality panels and parts. The installers acted professionally, drew on years of experience, and completed the installation quickly and without problems. She suspects the system might even earn her money back through excess generation, but hasn’t bothered to pursue that yet. The detail that sticks: after a year with the system, her household’s electricity cost amounted to $23.16, with at least one billing period showing a $10 credit.

Tracy I. needed solar for her ranch-style (LA) home and got an unexpectedly hands-on crew from Tier Drop Solar who drove up from Escondido. She watched Randy arrive the same week she called, walk her through the process and the installation plan, and even encourage her to compare other companies so she could be confident in her choice — a level of honesty that set the tone. She then watched Andrew, the electrician, methodically get every panel online, verify they were producing power, and show her how to download the monitoring app so she can see real-time energy production. The team finished the install on schedule, even in the middle of a city heat wave, which underscored their professionalism and commitment. What sticks with her most is that combination of upfront transparency and hands-on follow-through — plus the app demo that lets her check production live.

Brian had plenty of questions before committing to a solar installer, and he chose Tier Drop Solar for a residential rooftop system. He found Randy, Andrew, and Veronica to be consummate professionals who handled communication, the on‑roof installation, and follow-up support with clear, timely updates. The team delivered an installation that matched his expectations and then some: the panels and wiring looked neat and intentionally aligned with his roof’s natural lines. At the end of the job Randy climbed up with him so he could inspect the work in person, and that rooftop walkthrough — seeing the clean cabling and tidy layout up close — is the detail he keeps returning to when he talks about the experience.

Allyson called Tier Drop when the solar system on her home stopped working. A technician named Andrew came out, tracked down the fault and repaired it, and she paid a very reasonable price for the fix. She left a five-star review, remembering Andrew’s clear diagnosis and the affordable repair as the standout parts of the experience.

Benjamin S. picked a locally owned company for a rooftop solar installation after his roofer recommended Tier Drop Solar. Veronica set up the meeting and Randy came out to measure the roof, walk through the installation process, and put together a competitive proposal — he answered questions clearly and made the plan easy to follow. When the permitting process hit a delay, Tier Drop Solar made good: they added an extra PV panel and repaired a gate at no charge to compensate for the hold-up. The equipment and the quality of the work were top-notch, and dealing with Veronica, Randy, and Andrew felt straightforward and personal. He walked away impressed that the team not only explained the job well but also fixed the permitting setback with both product and service.

Craig had a five-year-old rooftop solar system from another highly rated installer, and as he prepared to buy an electric vehicle he wanted more production. He invited Randy from Tier Drop Solar to assess the setup and explore options to boost output. Randy converted the array from a string inverter to microinverters, repositioned panels for better azimuths, and added four extra panels. Over the first month after the work, the inverter swap and panel relocation raised daily production by at least 8 kW, and the four new panels contributed another roughly 5 kW a day — about a 13 kW-per-day gain in total. He found Randy experienced and focused on quality equipment and workmanship, and noted that friends and neighbors who used Tier Drop Solar had similarly positive results. The detail that stands out is the decision to switch to microinverters and optimize panel placement — that single change, plus the extra panels, delivered a dramatic jump in day-to-day generation within weeks.
