Big Ass Fans
Big Ass Fans entered the commercial business market in 2008, debuting a line of fans ranging from to in diameter. The following year, it began manufacturing fans in sizes suitable for residential settings. In late 2011, Big Ass Fans acquired a manufacturer of energy efficient residential fans. Haiku models incorporate direct current, permanent magnetics and aerodynamic airfoils making them 80% more efficient than conventional ceiling fans. They held the top 10 spots on Energy Star's Most Efficient 2014 list. In 2014, the company added smart technology SenseME to the Haiku ceiling fan. Haiku with SenseME integrates with the Nest Learning Thermostat through a smartphone app.
Skyline Solar
The output of the PV system can be increased with improvements in cell efficiency, the use of trackers, concentration, and other more subtle engineering improvements. Tracking provides up to thirty percent more energy per peak Watt compared to fixed tilt (non-tracking) systems. Controlling the temperature of the cells in a CPV system is critical to high energy generation because higher cell temperatures reduce the output of the panel. Skyline Solar uses a combination of tracking, cooling fins, and reflectors to focus light on a single strip of silicon cells and maximize energy production.
