"The total solar energy absorbed by Earth's atmosphere, oceans and land masses is approximately 3,850,000 exajoules (EJ) per year"

Divide by 365 days and you get 1.05 x 10^22 joules
per day.

1 cubic km of water evaporated water takes
2.26 * 10^6 Joules per kg times 10^12 is
2.26 * 10^18 joules.

So, about if about 5000 cubic km of rain occurs that's evidence of about a day of global solar energy being
released.
So take land area of 1000 km square [a million sq km] with
10 cm of rain in this area, it equals 100 cubic km.

Typhoon Tip:
"At its peak strength, it was also the largest tropical cyclone on record with a diameter of 2,220 km"
http://en.wikipedia.org/wiki/Typhoon_Tip
So that was 3.87 million sq km

"The typhoon produced heavy rainfall early in its lifetime while passing near Guam, including a total of 23.1 cm (9.09 in) at Andersen Air Force Base.[1] The outer rainbands of the large circulation of Tip produced moderate rainfall in the mountainous regions of the Philippine island of Luzon"
So on average over whole area 10 cm might be on the high side- but if that amount, it's 387 cubic km. So at most Tip dumped about 1/12th worth of a global solar energy day.

But I can't find any info on daily variations of total global rainfall.
This about cloud cover:
"Dr. Svensmark presents data from satellites that have taken pictures of Earth's cloud cover for the past 20 years. He noticed that the average amount of cloud cover could vary by 3 to 4 percent from year to year."

If I could get something on variation daily rather than yearly this could at least give some indication
