| Tennis Complex SOLAR WATER HEATING SYSTEM |
| solar water heating system was designed
for the tennis courts at the Cocoa Beach Recreational
Complex to provide hot water for the showers located at
the facility. The solar system, a typical residential
type system, is a "stand alone" solar heating
system capable of operating without utility power. The
system is powered by a small solar electric or
photovoltaic panel located directly above the solar
collector that serves as the system controller while
providing power for the pump. The system, a direct type
application, employs redundant freeze valves for freeze
protection. The system uses a flat plate solar collector to heat water for the showers in the Pro Shop. When the sun is shining, cold water from the bottom of the water storage tank is pumped through the collector by the PV powered pump, and returned to the top of the hot water tank.  The pump in this system, a "DC" pump, is driven by the small solar electric (photovoltaic) panel installed adjacent to the solar thermal collector. The small DC pump and photovoltaic panel replaces the "AC" pump, temperature sensors and system controller found in the typical solar thermal system. Making it 100% solar and capable of operating independent of utility power. |
