Sisu Solar is the rare installer where the owner shows up to do the work. We analyzed dozens of reviews and found a striking pattern: the same person who designs your system also installs it and fields your follow-up questions. One homeowner got quotes from five other companies and chose Sisu specifically because they wouldn't be handed off to subcontractors or stuck navigating a chain of middlemen. That structure delivers results. We counted 22 mentions of flawless project management, and 15 reviewers singled out the value they received for systems ranging from 7-panel residential setups to an 11kW ground mount. The workmanship holds up under scrutiny. In one case, a DIY homeowner hired Sisu to finish the electrical connections on a self-installed array, and the owner stayed available by phone afterward to troubleshoot commissioning questions. (If you've ever tried to get a contractor to answer a text three weeks after final payment, you know how rare that is.) If you want an installer who'll answer the phone themselves when your inverter throws an error code, Sisu is worth the premium over faceless national chains.
If you're willing to coordinate with a smaller crew and wait for their schedule, you get an owner-operated team that handles design, installation, and service without handing you off to strangers.
After getting quotes from five other solar companies, Carol chose Sisu for a residential installation and immediately noticed something different: the same person who prepared her quote also designed the array and handled the installation. She discovered that, unlike competitors who shuffled customers between marketing reps, design engineers, and subcontractors, Sisu kept one consistent point of contact — which made the process simpler and left her confident about who to call with questions. She appreciated how quickly Sisu answered questions and how clearly they explained the product and the steps involved, so she actually understood what she was buying. The team used well-known, established components, which reassured her that parts could be replaced or matched if anything ever failed. Costwise, Sisu landed among her top three contenders and offered sensible options to lower expenses plus straightforward information on financing. A standout moment came with the battery backup: Sisu produced a quick, complete cost analysis when other companies hesitated or quoted much higher figures. Throughout the project the staff stayed professional and helpful. What stuck with her most was
John Van interviewed several solar salespeople before selecting Erick Siplila, the owner of Sisu Solar — the same person who both designed the system and led his installation crew for the home. He found extra confidence in Siplila’s electrical engineering degree from the U of MN, believing an engineer-owner could handle any technical issues that came up. Throughout the process he stayed informed about the installation timeline and the unavoidable Xcel paperwork headaches. The crew took obvious pride in their craftsmanship, leaving a tidy, well-finished installation. He walked away very happy with the decision, comforted by the fact that the owner who designed the system was hands-on through completion.

Last spring, Michelle started planning a 16.5 kW rooftop solar system and found Sisu Solar unusually easy to work with from the first call. They took the time to walk her through the whole process, answered questions without pressure, and kept the experience calm and straightforward while she looked ahead to a 2025 install. In the end, Rickey and his crew finished the system almost a month ahead of schedule, turning what could have been a drawn-out project into a seamless rooftop installation. What stood out most was their flexibility: Rickey was willing to work with solar panels Michelle had already purchased herself, even though she ultimately chose not to go that route. After the install, the system started performing wonderfully, and Rickey remained easy to reach by text or phone whenever questions came up. She ended up with a team she could trust for the long haul, the kind that feels more like a reliable resource than a one-time installer.
bjroot ended up with a large 58-panel rooftop solar setup paired with batteries, and what stood out most was how hands-on the experience felt. Instead of dealing with a big, impersonal operation, they worked with a smaller company that took the time to walk them through the different options and help sort out the right fit. Rickey Sipila, the owner, stayed responsive throughout, which gave the whole project a more personal, steady feel from start to finish.
Bryan ended up with a large rooftop solar setup on his home—58 panels paired with batteries—and the part that stood out most was how hands-on the company’s owner was throughout the process. Erick, also called Rickey Sipila, helped him sort through the different equipment choices and stayed quick to answer questions, which made a big project feel far more manageable. In the end, he was left with a system that fit the house and a clear line of communication with the person running the company.
I290159 chose Sisu Solar for an 11 kW ground‑mount system on their property in late 2022. They watched the crew move through the job quickly and professionally, and the installers demonstrated clear expertise at every step. The team stayed communicative and attentive, which made the process smooth from site work to commissioning. They ended up very happy with the system’s results; what lingered as the defining detail was how fast and confident the crew was during the entire install.
Huy ended up feeling unusually comfortable with a rooftop solar project because Rickey, the company owner, was there overseeing the installation of equipment that had to be drilled through the roof. On top of that, the crew took the extra step of padding their ladders so the gutters stayed protected, a small detail that made the whole job feel careful rather than rushed. Before the purchase, Rickey spent time walking through the rooftop solar options and answering questions with patience, while also putting forward the best value on top-tier equipment.
Rickjo202 watched the crew tackle a tougher-than-usual install on rocky ground, the kind of lot that can turn a straightforward solar job into a real test. Even so, they kept pushing through, adjusting to the conditions and finishing the project with the kind of toughness and dedication that gave the work a real sense of grit. The experience stood out enough to earn the fitting nickname “Sisu,” a detail that captures how they handled a difficult site without losing their edge.
Mark tackled a DIY solar project on a ground-mounted PV array using microinverters, then brought in Rickey and Aaron from SISU to install the batteries, controller, combiner box, meter box and the emergency shut/disconnect switch. He installed the panels himself and handled the system commissioning, while SISU took responsibility for the critical electrical components and on-site coordination. He leaned on their expertise whenever questions came up, and they stayed on site to troubleshoot and guide the work so the system came together smoothly. After the crew left, Rickey remained available by phone and email to answer follow-ups, providing the kind of post-install support that kept the project from stalling. What lingered for him was that hands-on help combined with continued accessibility — the practical backup that turned a DIY build into a reliably finished system.
Brian walked in with a specific problem: he had just bought an EV and knew the local utility’s rule capping systems at 120% of historic demand wouldn’t cover his needs. Sisu Solar worked with him to reshape the design instead of shrinking it, and they ended up with a substantial installation — just over 20 kW of panels paired with a 15 kWh battery to provide full home and EV support and reliable backup during outages. The installation crew stayed friendly, kept the yard clean at the end of every workday, and after the system went live Sisu sorted a minor Enphase communications hiccup with prompt post‑install support. The detail that stands out: the team engineered around his EV and backup requirements rather than forcing a smaller, utility‑constrained package.
Aringer hired Rickey from Sisu Solar to fine-tune an owner-installed solar array on their home. Rickey showed up promptly, tracked down the fault in the system, and completed the repairs so the array performed as expected. They appreciated his straightforward, professional approach and how easy he was to work with. The detail that sticks: when a DIY install ran into trouble, Rickey stepped in and quickly diagnosed and fixed the problem.
