HAVRE DE GRACE, MD: Solar Energy Services, Inc. just finished installing a solar water heating system at Laurrapin Grille in Havre de Grace, MD. The system includes two, 80-gallon tanks and four, 4′ x 8′ solar thermal panels on the southerly facing roof. The system is expected to offset the restaurant’s hot water load by at least 50%.
The solar domestic hot water system consists of 10 panels, for a total of 400 square feet of collectors integrated with four, 120 gallon solar storage tanks, each with dual heat exchangers. On the same roof, SES installed a 22-panel solar pool heating system (920 square feet) designed to heat the main swimming pool during the spring and fall, saving Cherry Hill Management a tremendous amount of energy and money.
As part of the installation, SES also replaced the existing inefficient boilers with high efficiency modulating, condensing boilers (natural gas) integrated with the solar system to provide backup energy for domestic water heating. SES also installed crossover valves to allow Cherry Hill to divert solar energy to the secondary pool when the main pool reaches desired temperatures.
The thermal system utilizes six 30-tube Apricus evacuated tube collectors and two 120 gallon Vaughn Solar Sepco tanks.
WEST CHESTER, PA: Solar Energy Services, Inc. recently finished a solar thermal installation for the Housing Authority of Chester County (HACC).
SES was contracted by Johnson Controls Inc. to design, furnish, and install a solar water heating system that would offset a significant portion of the 90-person public housing facility’s conventional hot water load.
The system includes ten 4′ x 8′ flat plate collectors, mounted to the roof and with a closed=loop plumbing system, attached to three 120-gallon Vaughn Solar Sepco tanks.
The system consists of 30, 175-watt SolarWorld panels and a Sunnyboy string inverter.
On the same campus, at the Ellicott Dining Hall, SES also completed installation of a solar water heating system that will act as a pre-heat to the dining hall’s existing conventional system. This system consists of 20, 4′ x 10′ flat plate AET thermal panels on the roof, closed-loop plumbed to three 120-gallon Vaughn Solar Sepco tanks.
