Mounting the solar collector

The solar collector is mounted with the accompanying fastening brackets. Attach the rails mounted horizontally so that the collector can be placed into the mounting rail. The rail has screw slot so you can attach the screws which fits best with the underlying structure.

Installing the pipes between the solar collector and the heat storage

The solar collector uses a 22 mm pipe. You fit a pipe into the bottom of the collector and a pipe from the top of the collector diagonally to the inlet. These pipes must have contionous fall back into the heat storage and no water traps. The pipes must be well insulated. The temperature can be up to 100 degrees in the pipes to and from the collector. Insulated pex is a type of pipe that can be used. Below are details of the standpipe for the collector.

The coupling of multiple solar collectors

You can connect multiple solar collectors in an area up to 20 m2. We have developed a special adapter and tubes for this purpose so that you only pushes the pipe piece into the collectors to be connected together.

Assembly of 3-way valve, circulation pump and throttle valve

On the return side between the collector and heat storage you fit a 3-way solenoid valve, a circulation pump and a throttle valve in this order from the collector. The 3-way solenoid valve should open against the air as the default choice. It is pulsed while the circulation pump operates so that it closes the ventilation when the pump is operating. The circulation pump is a self-lubricating, self-priming pump and it must be dimensioned for the height of the facility and the size of the collector. The flow control valve is set to 1 liter of water per minute per m2 of solar collectors.

Mounting the system device

The system device operates the solar thermal energy system. You mount the control unit near heat storage. The control unit has two sensors, one to the collector showing the temperature of the collector and one to the heat storage showing the temperature in the bottom of the heat storage. The control unit also has a signal cable that is mounted to the circulating pump so that the solar thermal energy system receives the correct signals to start and stop. Via the system device you can read the temperatures and the production of solar energy at any time.

Installing the heat storage

The heat storage is mounted so that the solar collector water is circulates from the bottom of the heat storage and the return comes back in the top of the heat storage. The heat storage must be in a frost secure location. From the heat storage an overflow is mounted into the drain. Over overflow should run into the drain, but not in contact with the water in the drain.
