                         Solar panels project


•   S = 6400 m2
•   Installed power of 1067 kWpeak
•   Yield= 20%, S/P = 7 m2/kWpeak
•   For an energy E = 365x2,8x1067
                   E = 1,1x106 kWh

10% of the daily consumption

Cost of an installation integrated on the roof:
(6,5 €/kWh) => Investment: 7 150 000 €
(Roof renovation not included)
                          Solar panels project


• Electricity sold for 0,30€/kWh

• Electricity sold for 0,55€/kWh
 thanks to the integration prime

Sold in a year: 1,1 x 106 kWh/year x 0,5596 €/kWh = 615 560 €/year
Payback of the installation: 7 150 000 / 615 560 = 11,6 years


But we still need to buy 100% EDF’s electricity: 620 000 €
Conclusion: project not profitable !

• Monetary benefits
• Renewable energy : communication impact
• Subventions: ADEME




• Very high investments
• Works on roofs are compulsory and not included in the presented investments
• Heavy administrative issues

• Functioning of a fridge = geothermic heat pump technology
   – Cold does not exist: absence of caloric energy
   – Heat transfer from fridge to kitchen


• Geothermal heater
   – Extract heat from Earth and take it to Soprocos plant
   – Goal: substitute natural gas for the heat from Earth
                   Geothermic project


• Hole in the ground
   – 10 to 20 meters depth => constant temperature 12- 14°C
   – Each 100 meters T °C rises 3 °C
   – Well next to the boiler: depth 40m
   – Type of installation: water well => most efficient
     extraction method of heat
   – imagen

• Refrigerating liquid won’t harm ozone layer
• Evacuation of heat:
  – Radiant ground
                         + efficient: hot air rises
  – Radiant walls
  – Traditional system
                     Geothermic project



• 36 000 m2 x 0.78 = 28 080 m2 will be heated


• 12 000€ for 200m2 => 1 700 000 €, kind price= 1400000 €
• Mortgage:
   – 6 000 000 kWh/year gas used for heating
   – 75% energy savings
   – We will start to see money after 10 years

•   Economic and energetic benefits
•   Environmental
•   CO2 emissions reduced by 2/3
•   Durability: 25-50 years
•   Acoustic and aesthetic
