Guardian 120-64PV Complete Solar Hot Water System


Price: $0.00


Free heat from the sun, provides over 90% of your Hot Water.

Intelligent automation is the key to the Guardian Solar Water Heater's outstanding efficiency and self-sufficiency. The Guardian Solar Water Heater will turn on and off daily, collecting heat whenever it is available. The automatic controller alerts the pump when to run. It also alerts the automatic check valve to open, simultaneously. The pump then circulates colder water (from the bottom of your special solar storage tank) through your solar collector(s), and returns the heated water to the tank. This cycle continues as long as sun is available to provide heat to your water. When there is no heat available, the controller turns the pump off, and closes the check valve to prevent any loss of heat from the tank.

Circulation pump runs off of 10 Watt Photovoltaic panel.

2 Solar Collectors are 4'X8' each

Storage Tank is 120 Gallons and includes a 4,500 Watt back-up heating element. 

This is an Open-Loop System

System also includes...

Collector flush mounts, flashing, lag bolts, roofing sealant, copper fittings, 3 roof valves with fittings, 50ft of sensor wire, 50ft of 1/2 inch copper tubing, 60ft of pipe insulation, U-V paint for insulation, circulation pump, controller with sensors, ball valves, boiler drains, 6ft of 3/4 inch insulation, and owners manual.

The DPV System has a photovoltaic panel provides the energy required to power the pump. The solar panel converts sunlight into electricity. This electricity then powers the direct current (DC) pump. Thus water circulates through the system only when the sun is shining.

The DC pump and solar panel are suitably matched to ensure proper performance. The pump starts when there is sufficient solar radiation available to heat the thermal collector. It shuts off later in the day when the available solar energy diminishes. As in the D System, a thermally operated valve provides freeze protection or the collector can be manually drained.
