• What is a PV-T (hybrid) collector?
A PV-T collector is a combined assembly of:
• One PV module - for the conversion of electrical energy
• One Solar heat exchanger - for the conversion of thermal energy
• One aluminium frame work.
See for the explanation and functioning of the systems: “What is PV, what is ST”.
Besides heat extraction/conversion of the so called heat absorber system of the Solar Thermal Section, this absorber system has a second function:
The heat-absorbing and cooling of the PV-module.
Because of this a higher voltage output is obtained. ( up to 40%)
 


• What can be achieved with a PV-T collector?
With one/several PV-T collectors you can setup a so-called “Total Solar Energy System”, for both electric and thermal energy generation.
Also because of its cooling-effect on the PV module this system has a higher efficiency at a much lower cost price than separate systems “Good Price / Performance”.
In combination with geothermal storage / recycling, this system is very suitable for use by companies and institutions with relatively high hot-water and heat usage, e.g.
 
* Hospitals * Large Kitchens
  * Nursing homes * Breweries/beverage industry
  * Hothouse Horticulture * Food processing industry
  * Swimming pool/bath institutions * Laundries
  * Sports centres * Slaughterhouses
  * Hotels * Dairy factories
     
• Choice PV - ST or PV-T system
The sale of the obtained PV-energy (kWh) to the public power system, with application of the German EEG regulation is almost unlimited. So revenue will be guaranteed.
However the sale of the obtained ST energy/heat is dependent on the project. It is no use to obtain and store heat, if it is not used.
Therefore the installation to be selected must correspond with the annual energy usage of hot-water and/or heating of the buildings
 


• Design - calculation by project office
If you submit your energy consumption (over a year/ monthly periods) to our Project-office:
• Gas consumption in m³, respectively, oil consumption in litres.
• Electricity consumption (in kWh).
• Water consumption in litres (estimated in % hot % cold)
We will calculate a so-called Energy-Balance for you and an advice/tender adapted to your specific energy needs.

Depending on the total installed capacity,” Watt peak electric/ kilowatt thermal” and with
the application of the German”EEG Regulation”, which is in existence since 2004, at which a guaranteed/ subsidised kWh price for the delivery of electrical energy to the public power system is applied, it is possible to gain a output of 25% (horticulture), rate of return 4 till 5 years.

* Level 2006, when “energy-prices” remain the same, but in reality prices increase with 5 to 6 % per year.
