Solar Controllers and Temperature Sensors
The Solar Controller is the brain of our solar system.
The controller monitors the temperature in the solar collector located on the roof and also the temperature in the water cylinder or in the swimming pool.
During the night the collector will not collect any energy so the controller will switch the circulation pump off.
As the sun rises the collector will warm, as soon as the controller senses that the collector is 6 degrees higher in temperature than the water in the hot water cylinder, the solar controller will start the solar circulation pump, which transfers the heat to the hot water cylinder.
Our solar controllers can also store and output data to a computer or digital display.
DeltaSol solar controllers also have a freeze prevention feature which pulses the pump if at regular intervals when the collector temperature drops below 10c.
Our domestic systems use a 12 volt solar powered controller and 12 volt pump which is powered by a photovoltaic panel, a backup battery is also incorporated in the 12 volt system.
