ABSTRACT: In this paper, we propose an algorithm to compute the shading mask of any PV field based on its production data, GPS coordinates, and global solar irradiation for the site. The model is based on hourly production data, but could be extended to sub-hourly data. The detection of the shading mask through the production curve itself allows the operator to anticipate the production curve due to shading – and eliminate shading impacts in failure detection routines that can then concentrate on component (inverter, string, …) failure, so that operators can responde appropriately.

ABSTRACT: This article presents the lessons learned from the design and operation of a 300 kWp PV system installed, during spring and summer 2015, on the roof of a new logistic building located in western France. As this building is equipped with refrigerating units, thus with a high power consumption during hot and sunny days, it has been decided to consume the energy produced on-site without any regulated feed-in tariff but with a B-to-B contract, a first of its kind in France. In order to not inject power into the local MV distribution grid, the active power management feature of PV inverters has been implemented, also a first of its kind in France. This paper gives a summary of the detailed on-going monitoring campaign that aims to check if the actual power consumption of the site matches the consumption forecast and if the active power management feature of PV inverters has a significant impact on the total energy generation of this PV system.

ABSTRACT: In the center of the Lyon-Confluence district in Lyon, France, the public company in charge of the redevelopment of the area, SPL Lyon-Confluence, launched in 2011 an international design competition for the selection of a real estate developer to build a positive energy building on a 3.400 m2 piece of land called P plot.
The team Bouygues Immobilier/SLC in association with Kengo Kuma from Japan has been selected by the jury for the design of a group of 3 buildings called HAKARI with dwellings, offices places and shops for a total floor area of 12.300 m2. In order to build a positive energy building to respect the requirements set by SPL Lyon-Confluence, the selected team decided to equip this building with 2 kinds of PV systems: a see-through PV facade on the MINAMI building (21 kWp) and a rooftop PV system on the roof of each of the 3 buildings (168 kWp). The official opening ceremony of this building took place on Thursday 17 September 2015.

ABSTRACT: Following the conclusions of the successful task on Urban scale PV systems (Task 10) of the Photovoltaic Power System Program (PVPS) of the International Energy Agency (IEA), a pro-PV local building policy has been set-up for the purpose of the Lyon-Confluence urban project, a 150 ha redevelopment in the city center of Lyon, France, in order to make real-estate developers and architects design and build low energy buildings equipped with PV systems. This pro-PV local building policy was first tested in 2004 within the EC funded CONCERTO initiative by SPL Lyon-Confluence, the public company in charge of this redevelopment, for the construction of the first dwellings and office spaces of the area (A, B and C blocks). Now, with 10 blocks of the Lyon-Confluence area already equipped with one or several PV systems for a total power of 1.1 MW, this pro-PV local building policy has been improved and the use of PV will increase with more and larger systems. Thus, 6 other buildings will soon be equipped with PV systems for an additional power of more 1,2 MWp that will make the Lyon- Confluence area a significant solar city showcase.
