I have installed an RS-485 communications link to a Sunny Webbox, from SMA. The Webbox extracts the data from the inverter and passes it to the SMA web page for public display.

Later, I will be developing my own web page which will include my solar power data, along with current weather info with a live photo of the weather at the R J Ranch.
To view the current solar info, click the link, below:

At this site, put the zipcode 99163 in the search box. The "R J Ranch" will appear. CLICK on it

Weekly Update: 8/17/2008
COMING SOON: Live, real-time, performance figures!
Time connected to the grid: 110 hrs
Electricity produced: 115.00 kWH
Utility meter reads: 2214
Comments: I have added load to the system so that the utility meter runs slightly forward. This is because at the end of the year, if there is a negative value, (We've produced more power than used on location) we lose it ... no reimbursement. Therefore, the best practice is to owe a small amount to the utility company at the end of the year. To add load, I've transferred all of the outbuildings, well pump and koi pond air and water circulator pump to the solar system. This results in a load slightly exceeding the output of the solar power system ... a good thing.

Change in reporting schedule
We're making a change to the solar reporting. Soon, we'll have "real-time" reporting of the solar generation, hour-by-hour, including actual solar radiation being received. (Awaiting the hardware and software to facilitate this)
In the meantime, we'll be reporting statistics on a weekly basis, rather than daily, beginning on Sunday. The reporting period during this interim time will be Sunday-to-Sunday.
