What is the cylinder compression of a Toyota solara?

Unfortunately it's impossible to answer your question as stated. There are both four and six cylinder engines used in the Solara and the engines are different between the Gen I (to 2003) and Gen II (2004 to current) models. It's likely compression readings are different between all the engines. All is not lost though. You'll find the answer to your question in the factory service manual and that's available for download from Toyota here: https://techinfo.toyota.com . It'll only cost you about ten-dollars to download for two solid days. In that time you could download every manual for every Toyota and every Technical Service Bulletin too. It'll be the best money you ever spent on your car. Cheers
