Description
The solutions consists in the installation of photovoltaic (PV) panels on the building roof or on the façade. This installation can be of several types:
Design and implementation
Strenghts
- Modular, large variety of applicable capacities
- On-site generation possibilities
- A large variety of possible applications
- Relatively small spatial variations of resource
- Incentives, in majority of cases
Weaknesses
- Intensity, in terms of full working hours
- Seasonal dependence, variability, time profile of expected energy production
- Complicated procedure regarding the legal framework
Opportunities
- Cost reduction and grid parity
- Development of smart grid and electric vehicles
- Electrification of remote and off -grid areas
Threats
- Shortage of main raw material – increase of cost
- Unstable, excessive market
- Legal barriers – quantity based incentive schemes, legislative issues
Example
Saint Denis, France
A photovoltaic curtain wall was implemented in June 2015 to retrofit the South facade of a collective building (total surface of the façade: 400m² – 38m x 11m). 250m² of PV panels have been installed, with an aluminium structural frame. The characteristics of the PV installation are the following:
- Nominal power: 23 520 Wp
- Generated energy: around 17 000 kWh/an
- Total cost (including studies, installation, commissioning) : 260 000 € HT
