In Europe there are several systems. I guess you need to surf the internet for more information using the terms of your question.

One such system is now working in an Indian Hospital - http://www.absolicon.com/ --
Solar PV and thermal – a marriage made in heaven? - http://www.renewableenergyfocus.com/view/10922/solar-pv-and-thermal-a-marriage-made-in-heaven/
First installation completed in India
The first Absolicon installation is completed in India. Absolicon has installed solar collectors on a hospital in Mohali, India. - http://www.absolicon.com/first-installation-completed-in-india/ -- Solar energy at Indian hospital
A 100 m2 solar collector ensures that the hospital in Mohali has both electricity and hot water for its operations. The system is installed on the roof. Some 50 m2 consists of an Absolicon X10 PVT system that generates electricity and heat. The other 50 m2 includes Absolicon’s model for higher temperatures, T10, which can be connected to a solar cooling unit for the hospital’s air conditioning system. The purchaser is Bergen Group, Absolicon’s partner in the Indian market. The system was unveiled on 22 April 2012 at a ceremony.

some interesting information can be found on www.newformenergy.com/hybrid-solar-solution which explains optimalisation of solar energy. One of the problems of traditional PV is the efficiency loss of about 0.5% per degree increase of the panel. panels can easily become 100 degrees in full sun, thus loosing a substial converson power. The hybrid solution cools the panels down by water (and heats the water). such solutions are cost efficient when apart for the need for electric power also hot water is needed.

In Canada they developed solarwall, see solarwall.com/en/products/solarwall-pvt.php and received an 2010 energy award. The system produces about 4 x the energy as compared to the same surface of conventional systems.
