better generation

@ mileshc
The Power Predictor takes a reading every 10 seconds and an average every 10minutes.
The sample rate can't be altered by the user.
The data logger is compatible with a SD card up to 2GB. As the device only uses 7.2Kb/day the included 512Mb memory card is certainly sufficient!
Average current consumption is 24uA.
The Power Predictor uses a CdS.
The solar sensor has been calibrated to show Watts/m2 on the online software.
There is an annual license renewal fee of £40.00 to access the online software.
The data is stored in CSV format.

Hello, I assume the previous poster is asking what the sample rate is? i.e at 5 minute intervals?
Can the Sample rate be altered?
What is the largest SD card it can use i.e. 4gb?
What is the current consumption? (a lithium cell might be better?) or perhaps a small solar cell add on or mod?
How do you calculate the solar energy?
Do you use a CdS or photodiode?
If collecting data for more than a year or wishing to reuse the device on another site after a year, are there any costs to use the on-line service?
What file format is the data stored as? i.e ISO/IEC standard OpenDocument Format ODF or CSV?

Cheers
