2POWER SYSTEM QUESTIONS AND ANSWERS

2Power modules are not installed differently from conventional photovoltaic systems. The modules are mounted on the known rail systems or brackets.

The hydraulic connection is made with hoses that are inserted into the connection mouths of the modules. The hoses are flexible, weather-resistant and protected by a metal mesh.

The feedline system must be able to withstand temperatures up to 60 ° C and be insulated against condensation. PN10 pressure level is sufficient (no high-temperature installation required).

They can also be led along the facade of the house via the roof construction in the heating room. To bring the feeding lines to the attic, they are pushed in by a conventional solar panel. From here the lines can be transported to installation axes (such as a free chimney or air shaft).

Each individual module array is configured so that the adjustment valves are hydraulically equal. The system can also be built using the Tichelmann system.

The control is done by the solar controller. Two temperature sensors record the temperature in the module and in the storage.

When there is a positive difference, the pump is switched on and the flow is controlled by the rotation speed. For sanitary purposes we offer a hot water layered thermal storage for heating drinking water.

A special glycol-based water mixture is used as heat transfer medium. The system is therefore absolutely frost resistant.

24 kg in filled condition, the weight for the glycol filling being only 1 kg thereof.

Yes. The bottom plates for the roof hooks are screwed securely to the roof trusses with long screws that penetrate through the slats and underlay.

The supply lines for the 2Power modules are run from the heating room through the supply duct to the roof. The line is then guided between the rafters to connect to the module field. The line is then ultimately guided through a so-called solar tile to end on the roof tiles. Once there, it should be placed behind the module field, which is installed later, so that it's not visible.

De verhouding antivries in de solaire vloeistof moet worden aangepast aan de locatie van het moment van opstarten.

Basically that is possible, as long as they provide sufficient flow, can withstand the system pressure of max. 6 bar, and are made of anti-corrosive material.

This may only be done after careful checking with the manufacturer.

The dimensions of the components are shown in the installation and operating manual.

The dimensions of the components are shown in the installation and operating manual.

Basically this is possible, however, it has to provide sufficient buffer volume and have an anti-corrosive solar exchanger which also has sufficient permeability.

The number of 2Power modules is designed according to the heating requirement and the storage capacity. In other words, the modules will only be all 2Power if the heating requirement or the storage capacity is correspondingly large. Otherwise, 1Power modules can be used for electrical power generation next to the 2Power modules because they look the same.en.

We use inverters from the Germany company SMA Solar Technology GmbH.

We assist with the plans and can prepare individual calculations at the time an order is made if desired.

Yes, the system yield is included in the energy balance for the building.

If the 2Power modules are combined with an oil or gas heater, 250 L or 250 dm3 up to 500 L 500 or dm3 can be saved for a 5-member family. For an integrated heating remodel that includes installing a heat pump and long-term thermal energy storage, no oil or gas is needed any more.

The roof slope must be at least 10°. This is necessary just for cleaning purposes.

Installing a 2Power system is always worthwhile for the environment!

Of course. In fact, that works very well!

Yes! This combination of systems, in fact, has a very high yield and the best possibility for savings.

Of course. The module complies with the following standards:

EN 64215: 2005
EN 61730-1: 2004
EN 61730-2: 2004

The module is thermally qualified according to ...

DIN EN 12975-1: 2006
DIN EN 12975-2: 2006

In Kleinostheim, Germany.

Your installer, roofer or electrician can make you an offer for the system.
