Changed the array's angle over the weekend finally. It's now at 40 degrees, optimised for spring/fall sun. I noticed better power into the evening compared to the evening before the angle change with similarly sunny days.
When I originally built it, I didn't built with spring summer angles in mind (for some wierd reason) so I had to add support in the middle of the array to keep it from sagging . Last edited by jwxr7; 03-16-09 at 10:00 AM.. |

They were pretty bad until late last week when the sun started shining again. I had 2 record days in a row over the weekend. I'll post some #s soon.

Interesting sway in numbers, really bad from the 7th to 10th, then really awesome from 13th+.

I just noticed that in 4 days it will be time to change the angle of the array for summer already . I guess I better figure out what size legs to make. Maybe I can just move the bottom of the spring/fall legs to get the angle.

Not too horrible of a setup for free. Still any idea of what percentage of your total electric use that is?

I just checked my last utility bill and averaged the last years electric consumption to 21.7kwhrs per day. So in a month I can make up 1 day's worth of consumption. What's that, like 3.3% or so?

I had 2 different power outages in April. One was just long enough to erase the Kill-a-watt memory and the other lasted 25 hrs. So April production was 25.74 kwhrs, or about 919.3 whrs/day (using 28 days because of power outages).
On May 10 th I changed the array to the summer angle. The month of May saw 32.88 kwhrs of production, or an average of 1061 whrs/ day. I need to try modding my kill-a-watt to have battery back-up. |
