Time connected to the grid: 16 hrs

Electricity produced: 15.1 kWH's

Solar Energy: 580 Langley's (A Langley is a unit of measurement for total solar radiation)

Utility meter reads: 2227

Weather: Mostly sunny

Comment: I tested the electric production using a "semi-automatic" solar tracker. (Semi-automatic = I moved the panels every hour!) You can see from the data that we got about 25% more power.

"Semi-automatic" tracker in action. The time is about 9am. The panels are pointing virtually East, rather tha the normal South orientation.
