Comment: Heavy electric car useage. Four trips: 80+ miles. (Each round-trip to Pullman uses about 8.5 kWH. If I were paying to recharge the car from the electrica grid, which I am not, it would cost about 44-cents.

Comment: Production was down again today because there was no sun tracking. The array was fixed pointing south. Tomorrow we will resume full "semi-automatic" sun tracking.

Comment: Production was down about 19%, even though the sun energy available was the same, because the solar arrays were not "semi-automatically" tracking the sun. They were set and fixed at directly south.

Comment: I installed the fifth solar panel mounting post today. it is 48" deep in concrete, 18" in diameter, same as the others. This post will eventually have four more solar panels, making a total of twenty. For the next year, however, it will not be tied into the system, but will be used to test and develop a reliable and inexpensive sun tracking system.

All Dressed Up And No Place To Go

This was Inauguration Day for the system. Inland Power, our electric utility company arrived and "blessed" the system. We are now legally tied into the US power grid. For anyone buying "Green Tag" power, you are surely getting a few electrons that were generated here on the R J Ranch.


Having said the above, the weather today was absolutely terrible: Rain, rain and more rain. Almost half an inch, pretty evenly spread over the whole day. You can see by the chart, it was the lowest in solar radiation and the lowest in electrical production, for a full day's work.
