Mounted on the Field Lab roof is a solar panel which is part of the solar hot water system in the building. The thermal collectors in the panel feature coating with an absorptivity rating of up to 0.96--one of the highest efficiencies in the industry. Without this system, heating water would otherwise consume roughly 4 to 5 percent of the electricity used in the building; in other words, this solar hot water system reduces the electrical consumption by approximately 5 percent during the year. It is estimated that heating water may account for up to 30 percent of home energy costs. |
