Late 2009 MBP 15" battery drain on sleep after putting SSD and ram upgrade
You probably have one of the following enabled that could explain the power drain.

Power Nap or Wake on WiFi, disable them, 

or read the small print that says what it will do in sleep :)



Also as said earlier, open the Console and type "Wake" in the search window of the Console.

Now look who and what is waking it up and what is it  for what reason and what is it doing about it.

As for your question why is it consuming more power, well you added more lights to the Christmas tree.

For example when HDD sleeps it does not consumes any power. The cussing SSD does consume power since it reshuffle it self from time to time, that is normal for SSD to refresh its memory cells.

UPDATE:

according to apple, you computer does not support the Power Nap mode settings thus enable/disable activity during the sleep.

So back to the Console reports:

Type "Wake" and look what is waking it up or keeping it awake based on time stamps.

Going on a limb, I would say it is your Trim support for the SSD, that you will find in the Console.

The TRIM command is an important disk command for SSDs that keeps your flash memory appropriately cycled so that you can achieve faster read and write speeds, as well as a longer lifespan for your SSD.
