The Perez family solar systems consist of both solar thermal (hot water producing) panels and solar PV (electric producing) panels with fifty three in total. The first PV array was commissioned on January 5th, 2007 and has 22 – 130 watt panels with SMA inverter which makes it a 2.86 kW system. This was the first grid tied installation on C & L Electric Cooperatives system. It was designed by Bill Ball of Stellar Sun Little Rock, Arkansas.
The second phase of solar PV commissioned on March 25th 2011 at the Perez home consists of a dual axis solar tracker which holds 16 – 190 watt panels and uses a SMA sunny boy inverter. In addition to the solar tracker, a 12 – 190 watt panel array is installed on their detached shed using a Fronius inverter. The combined arrays in the second phase make a 5.32 kW system with the tracker producing 30 percent more energy than the fixed array. The second phase was designed by Hopmann Solar Energy of Dumas, Arkansas. The combined PV systems total 8.18 kW and produce all of the electric energy needs of the home.
The solar thermal system commissioned in December of 2010 consists of three 4 x 8 foot Heliodyne flat plate collectors with a combined square footage of 96 square feet connected to 240 gallons of storage capacity. The hot water backup system is made up of a 9.4 gallon per minute Rinnai tankless water heater using propane. This robust system can provide hot water to the large family even through a few days of cloudy weather. The thermal system was designed by Hopmann Solar Energy of Dumas, Arkansas.
