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

  Jan  Feb  Mar  Apr  May  Jun  Jul  Aug  Sep  Oct  Nov  Dec Year
   95  148  256  316  427  440  427  388  290  201  108   74 3171 cumulative
  3.1  5.3  8.2 10.5 13.8 14.7 13.8 12.5  9.7  6.5  3.6  2.4  8.7 average/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 :

  Jan  Feb  Mar  Apr  May  Jun  Jul  Aug  Sep  Oct  Nov  Dec Year
   81   68   54   57   45   43   46   33   55   61   36   47 2002
   63   61   46   58   40   42   50   51   54   56   44   42 2003
   42   49   63   52   45   46   38   45   43   34   40   45 2004
   49   73   69.4 52.8 33.2 41.3 51.7 28.3 44.9 50   55.8 71 2005
   68   75   62.5 22   18   31   46.5 31   44   42   44   48 2006
   42   41   49   57   45   34   35   28   44   59   68   63 2007
   49   40   44   53   27   42   33   24   45   61           2008

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$/€).
