You really need to have a solar audit done as each roof is specific. Example, poorly orientated roof in Southern California may not work as well as a roof in New Jersey.

There are some online tools that you can plug in your address and it will give you some cursory feedback on the applicability and feasability of it in your application.

Short answer - not great, because of northern latitude and the fact it is the 5th cloudiest major city in the US - 229 cloud covered days a year. However, there are some houses facing south or west that catch enough sun to be near viable seasonally.

Seattle Light and the City of Seattle have done several studies on this, and have LOTS of info on their websites - as does PG&E out of Portland - similar weather, even though not serviing your area. Google this search phrase - Seattle Light solar efficiency reports - and I think you will find more info and advice than you wanted.

Disclosure - I used to work for one of the companies that Seattle Light study and solar energy installation credit analysis and report, but hopefully that will not turn you away.
