When the FitClub in Springfield, Illinois decided to trim its energy costs and further promote a healthy lifestyle they contacted C. Power Design to do the installation. After evaluating the site Daniel G., an executive at C. Power recommended Tigo Energy’s Maximizer system for the array. “The Tigo Energy Maximizer system is a great asset for a solar installer,” Daniel G. said. “Using Tigo Energy on my solar installs differentiates our product offering and enhances the value of solar to our clients. The systems are simple to install, make arrays plug and play, and provide great tools for monitoring and improving security. I recommend Tigo on all the installations I do.”Even though the FitClub is a flat metal seam roof, the Tigo Energy system improved energy yield by over 11%. In Illinois, clouds move frequently over these arrays and the Tigo Energy system is able to stabilize the array through these quick changes in weather patterns. The monitoring system also picked up a faulty diode, which was dragging down the performance of the array. “If the Tigo system was not in place, we would not have noticed this.”

When the Dingmons wanted to put a solar array on their home in Lebanon, Oregon they wanted to ensure that their array would conform to their existing rooflines and still produce adequate power. National Solar Inc., the installer, reviewed a number of options for achieving power production from a shaded, multi-tiered array.
“The Dingmons have big beautiful oak trees all around their property,” said John Harley, National Solar's Production VP. “This left only a small piece of roof that had enough sunlight to justify an array, unfortunately this section of the roof was small and had a split roof-line.”
After evaluating racking, microinverter, and other solutions National settled on Tigo Energy. “We went with this approach,” said Kim Berhorst, “because the Tigo Energy system is simple. The Tigo hardware is small, fits inside the frame of a module, and has a much higher reliability than microinverter architectures. It will also produce more energy than other solutions, given the extremely high efficiency of the maximizers and central inverter.”
The Dingmon system has gone online and is showing between a 25 and 30% improvement over a traditional system. Tigo Energy boosted the system's production, from an estimated output of less than 70% of the total solar resource (TSRF) to an estimated TSRF of over 80%. With Tigo Energy systems, projects with marginal TSRF rates can qualify for incentives like the new Oregon FIT pilot programs.
"The system has performed very well and consistent with the varied weather we have in this area," said system owner Sidney Dingmon. "I am pleased with the way the Tigo system has given me a means to monitor the performance of the system . The systems performance is greatly enhanced with the addition of the Tigo system. I am very pleased!"
