Sun Supply PV reviews

JayJahy M. turned to Tandem a couple years ago to replace aging BP panels on his rooftop system, upgrading to more powerful panels and ordering new racking and wiring for the install. He discovered Tandem’s team to be knowledgeable and helpful, and they provided a complete parts quote very quickly. After he placed the order, the components arrived promptly and professionally via the company’s solar products delivery vehicle. Everything in the shipment matched the quote — correct and complete — which made the rooftop installation straightforward. He ended up with a modernized system supplied near wholesale and felt the company would stand behind its gear. What stuck with him was the hassle-free delivery and the fact that every part fit as expected, so there were no surprise trips for missing hardware.

About a year and a half ago Bill purchased parts for a roof‑mounted solar setup and discovered this company offered the best price and the small fittings he needed. Greg walked him through the leftover pieces and made the installation straightforward. The standout moment came when they accidentally shipped IQ6 units instead of the IQ6+ he ordered — one phone call later they dispatched the correct models the same day. He mailed the wrong inverters back five days after receiving them and the company processed the exchange without the usual RMA headaches, treating the error as if it never happened. He plans to buy from them again when he expands his system.

Sam L. stumbled across the company online and decided to purchase their entire solar system. They worked closely with sales agents Kourtnee and Sean, who guided the process smoothly and kept the paperwork and order details accurate. The equipment arrived quickly, and the price came in far better than expected. The thing that stuck with them was the combination of attentive sales support from Kourtnee and Sean plus fast, correct delivery.

Michael shopped every DIY seller he could find and settled on Tandem Solar when he needed a 10 kW system for a roof with limited space. He worked through the project with Sean, Greg and Sarah, digging into every technical detail and firing off a steady stream of questions — and the team stayed patient and thorough the whole way. The system arrived in one delivery to his driveway, and Tandem even arranged for an engineer to produce the calculations and site plan required for the permit, so the package felt nearly turnkey. Because of the space constraint he opted for the highest-efficiency panels they offered; they were the priciest in Tandem’s catalog but still cheaper than other quotes he’d received. He only had to buy a bit of cabling and a conduit for the home run himself — everything else came from them. Now that the company has reorganized under a new name, he’s watching how their setup evolves, but their pricing still looks competitive; he’s considering adding four more panels and plans to have them quote first. What stuck with him most was getting a competitively priced, permit-ready system delivered to his driveway with virtually all the details handled.

Rob, a homeowner in Minnesota, hunted through extensive research and found Sun Supply PV to be the perfect fit for his solar project. He discovered their pricing and product lineup outmatched every other bid he looked at — one competitor even urged him to take the deal because they couldn’t compete. From purchase through plans and structural engineering, the company kept communication smooth and answered his questions at every step. When wildfires were raging nearby, they stood firm and continued to process and fulfill his orders rather than pause the work. Order, plans, engineering and delivery all arrived on schedule and met his expectations; he made clear he isn’t endorsed by them, only impressed. The detail that lingered with him was their ability to keep the project on track and on time even while operating amid the wildfires.

J turned to Tandem for the permit-drawing package and to purchase equipment for a DIY residential solar project that aimed for moderate-to-high-end components. They discovered an impressive selection of products and competitive pricing that matched the wish list, and they encountered Sean and the rest of the staff as exceptionally helpful, friendly, straightforward, and responsive. The design work proved solid, though it arrived later than hoped because Tandem was handling a heavy workload. In the end, the permit-ready drawings and the gear Tandem supplied let them finish the installation themselves. The detail that stuck with them: Tandem carried the exact higher-end components at prices that made the DIY approach practical and successful.

Charles B. invested north of $30,000 in a large home solar array and ended up with dramatic savings — his electricity bill plunged from about $600 a month in the summer to just $11.35 per month so far. Early on, several dozen panels arrived damaged by FedEx, and he discovered the policy that set this company apart: customers pay the installer, and the installer pays the carrier, which meant the company handled the freight claim for him. He called, reached a real person quickly instead of being stuck in an automated system, explained the situation, and the company walked him through next steps and shipped replacement panels immediately. There were a few hiccups throughout the install, but their willingness to take ownership of the shipping problem — rather than leaving him to deal with the carrier — made the difference. He plans to do business with them again because they fixed the mess fast and delivered the savings he expected.

David R. shopped around online for solar components and discovered Tandem had the most aggressive pricing he could find. He sent them his city-approved plans and they dug into the drawings, returning a clear punch list that made the install easier to plan. Tandem shipped the full kit; after a minor shipping hiccup with FedEx or UPS, the company stepped in and took care of the problem quickly. During the install he ran into a few newbie questions and Tandem patiently walked him through the answers. When a couple of small parts fell off the roof and went missing, Tandem shipped replacements the same day. He ended up with a complete system, competitive cost, and prompt, hands-on support — the same-day replacement parts and patient installation help are the details that stuck with him.

Sunghuang L. purchased 18 solar panels and ended up receiving the wrong model. They were promised a refund, but the company went quiet after the initial agreement and several follow-up attempts drew no response. Frustration mounted until they escalated the issue — finally, Sean stepped in and pushed the refund through. The memorable detail: the refund only materialized after a specific staff member intervened, so prospective buyers should be prepared to follow up and ask for a named contact if something goes wrong.
