Dear, administrator!

I'm Jason B. Park.
ECOTECT really amazes me because of its various functions.

I want to ask you about the differences of solar access analysis and solar exposure.

I had progressed the solar access analysis and solar exposure after choosing the surface subdivision and I could get the results data.

I progressed the solar access analysis of subdivided surface, the incident solar radiation during all year and got the data of cumulative values and average daily values.

On the other hand, I progressed the solar exposure(total monthly, average daily with incident) of same subdivided surface(same surface those solar access analysis).

And I compared the results of solar access analysis with the results of solar exposure.

But the results are so different. The all year result of solar access analysis is about 989.71kWh/m^2 and the sum of each month result of solar exposure is about 578.06kWh/m^2. So, I don't know about the reasons.

Of course, it is same area, tilt(33°), location, weather etc.

I really appreciate it if u give me some explanation.

Thank you and Regards
Jason...
