40 € ... it's not that bad ... according to:

2. From 01/12/2011 to 31/03/2012.
For each MWh of electricity produced, you will receive a number of green certificates varying from 7 to 5 depending on the power of the installation for a period of 10 years.
Thus, for a photovoltaic system <10 kWC:
The first 5 kWp (peak kilowatt) will give the right to 7 HP / MWh of green electricity produced, i.e. approximately 1 HP each time the system has produced 143 kWh,
The following 5 kWp (from 5 to 10 kWp) will give the right to 5 CV / MWh of green electricity produced, i.e. 1 CV each time the system has produced 200 kWh.
For 1 MWh of solar produced on an installation of <5 kWp, we therefore gain in Belgium on an installation installed in early 2012 (after the calculation is more complicated, because annualized, but you can do it):
- 200 € / MWh to save electricity (around 0.2 € / kWh on average in Belgium)
- 7 * 40 = 280 € / MWh if the CV increases to 40 € (455 € with 65 € guaranteed)
Total at 40 € / CV = 200 + 280 = 480 € / MWh or 0.48 € / kWh
Total at 65 € / CV = 200 + 455 = 655 € / MWh or 0.655 € / kWh
Loss of 480/655 = minus 26% ... it's not that bad! Obviously, some will no longer have golden balls (see *) ...
But the Walloon region, if it does not want to make big civic enemies, has every interest in distinguishing between the contracts signed BEFORE and AFTER this change ...
But the drop in green certificates, like the price adjustment in France last year, is not so serious, because the market will adapt and faster than you think (we bet?). .
what is scandalous is the loss of state guarantee on existing contracts and therefore on installations for which * the price has been set quite arbitrarily on this guaranteed state profitability (= overbilling to benefit from aid)!
Reminder: the "Chinese" price of the WC is less than $ 2!
ps: but green certificates are not supposed to be financed by polluting industrial activities (on CO2)?
