Here is the forecast production for my PV solar panels system in kWh per month/day :

From EDF's 2007 yearly report, here are the CO2 & radioactive wastes generated by kWh produced in 2007 :
- CO2 : 59.1 g/kWh
- long life (>100,000 years) : 0.9 mg/kWh
- short life (<300 years) : 10.0 mg/kWh
Looking at EDF's monthly reports, here are the CO2 generated in g/kWh :

As you can see they are fluctuating a lot...
From a 2005 study, this is because they are mainly using coal power plant (900 gCO2/kWh) to reply to quickly fluctuating demand. While European average is at 340 gCO2/kWh, the French production can be separated by use :
- heating : 180 gCO2/kWh (129-261)
- lightning : 100 gCO2/kWh (64-151)
- intermittent use : 60 gCO2/kWh (38-93) (cooking, washing...)
- continuous use : 40 gCO2/kWh (20-72) (cold, cooling...)
Based upon EDF's 2007 yearly report, our 3kWc photo-voltaic solar panels should save :
- CO2 : 187 kg/yr
- long life radioactive wastes : 2.85 g/yr
- short life radioactive wastes : 31.7 g/yr
The reselling price is currently at 0.57187€/kWh, so the income for the first year should be around 1813€ (2284$ at 1,2595$/€).
