This needs use of trigonometry. A pitch of 7.5/12 = 0.625 This means that the tangent of the angle is 0.625 Using trig tables or calculator, find the angle whose tangent is 0.625 The answer is 32 degrees

7 degrees is 1 1/2" rise in one foot.
3 degrees is a slope of 5.24 centimeters per meter. (rounded)
"pitch" can be measured in degree or percent drop. So, if you drop 6' vertically over 24', you would the pitch, or slope, would be 25%. Expressed in degrees, given that 90 degrees is vertical, it would be 25% of 90, or 22.5 degrees of slope.
The earth receives an average of 164 watts per square meter from the sun. This is the average spread over the world including poles and tropics, night and day. The energy in units used commonly in commerce (kilowatt-hours) would be about 45 millionths of a kilowatt hour per second per square meter. More important is the calculation of how much usable energy reaches the ground where the energy could be put into use. At 40 degrees latitude (the rough middle of the US) during the 8 peak hours of the daylight, each square meter will receive about 4.8 kilowatt hours.
