Solar on atypical, steeply sloped roofs – pv journal Worldwide


The French firm HDF Energy has geared up a brand new polymer electrolyte membrane (PEM) hydrogen fuel-cell manufacturing plant with a 500 kW photo voltaic mission, by adjusting the PV modules and inverters to suit the sawtooth roof design.

French hydrogen specialist HDF Energy just lately commissioned a brand new manufacturing facility in Blanquefort, western France, the place it’ll manufacture high-power PEM hydrogen gasoline cells for the maritime and rail heavy mobility sectors.

To present the constructing with renewable electrical energy and for the check section of the gasoline cells, the corporate selected to put in a 500 kW self-consumption solar energy plant on the roof.

“This is a reasonably complicated roof designed by the group Patriarche Architectes,” Christian Baudon, president of the French consultancy Christian Baudon Conseil, stated. pv journal in France. “it has 12 warehouses giving it a sawtooth look typical of commercial workshops.”

The firm is accountable for the design of the PV system and at present manages about ten C&I tasks in logistics, business, manufacturing facility and airline buildings within the Bordeaux area, in addition to round Carcassonne and Perpignan.

“The solar energy plant is made up of 12 blocks of 41/42 kW every,” added Baudon. “We use 4 Sungrow SG110CX inverters positioned on the roof, with three sheds per inverter and 18 strings per inverter.”

The facility additionally featured 1,149 Trina Solar TSM-435 W modules, put in on the southern slope of the roof by French EPC contractor Eiffage. The mission began in September 2023 and must be accomplished inside one and a half months.

“One of the primary difficulties is the climate,” stated Baudon. “The slope is 38 levels, and the roof turns into an ice rink when it rains.”

Due to this steep inclination, the modules are mounted on a metal tray with a “mini-rail” fixing system from the German supplier Novotegra.

The firm didn’t say how a lot it invested within the mission, however stated the levelized value of power (LCOE) over 20 years is between €0.03 ($0.0325)/kWh and €0.04/kWh.

“Based on one gasoline cell produced per thirty days, which was initially deliberate, the manufacturing of 578 MWh/yr of P90 and 626 MWh/yr of P50 will make it doable to realize a self-production charge of 83% and a self-consumption. charge of 20% to 30%,” stated Baudon. The surplus might be injected into the community at €0.114/kWh.

“Next, if HDF Energy switches to 2 gasoline cells which can be produced per thirty days, the plant’s manufacturing will certainly not be sufficient for high quality exams,” stated Baudon. Two prospects open up: getting inexperienced electrical energy from different sources or growing the ability of the solar energy plant.
