Hi all,

are there any PV measurements around?

I'd like to get a better idea concerning optimum cell orientation for
real life.

I'd like to see e.g. a weekly average of energy vs. day of time. This
would require multiple measurements a day, including date and time
stamp.

Additional info: cell area, latitude, orientation, inclination.
A good extra info would be the outside or cell temperature.

I'd like to gest some visualisation converning the best orientation,
which does not only take a very basic average assumption (mostly based
on 'orientation = south', 'inclination = latitude + x'), but better
assumptions concerning the real application.

Thanks,
Martin - Freiburg, Germany

There is a tool for sites in the US based on actual observations from
several sites.
http://rredc.nrel.gov/solar/codes_algs/PVWATTS/version1/


http://solardat.uoregon.edu/SoftwareTools.html has some tools that show the
sun path across the sky.

http://www.gcstudio.com/suncalc.html provides a listing of apparent solar
positions for a particular day.

http://www.akeena.net/solar_electric_systems/monitoring.html
has some live reporting viewable online.

Thanks. The year is selected as 'meteorologically typical', but every
month may take a different of those years.

That's very close to my needs. But it's a summary only, while I look
for raw measurement values.
