I will soon be installing solar panels on my house and I am wondering if there is readily available data on the amount and intensity of sunshine that would correlate to daily potential solar energy production? When I look at my weather data from Environment Canada I don't see any sort of data for sunshine, or whatever. And what is the common measure for the amount of sunshine? Solar radiation, something else? Occasionally you will see a UV factor but I think this is a daily maximum number that likely wouldn't be what I am looking for.
