Objective
To study the aesthetics of a pv system attached to a university building. It is the first grid connection in Spain, (apart the big pv systems of the utility companies). Electricity back buy price and technical conditions are to be negotiated with the utility company.
On the newly constructed building of the Institute for Solar Energy at the University of Madrid a conventional 16.5 kWp pv system is attached to the facade, the tower and the roof terrace in an aesthetical way.
A 12 kVA inverter is used for the grid connection. The local utility is not involved directly in the project, so the buy-back agreement will be negotiated in a realistic way.
28 MWh/year are expected.
Nr. subsystems : 3 (facade, tower and terrasse)
Power subsystems : 5.7 (facade) + 3.1 (tower) + 7.3 (terrace) +% 0.5 (tower II) kWp
