Welcome to European Tribune. It's gone a bit quiet around here these days, but it's still going.
I have done some analysis of the solar potential of the roof of my shop. Removing some trees to the south west of the shop would keep the roof in sunlight from 9AM to 4PM even on the winter solstice - 7 hours. A compound tilt mechanism that tilts the entire array up 20 degrees on the west in the morning and in the east in the evening, combined with individual panel tilt of up to 15 degrees in either direction would keep the entire array in its optimal zone for five hours a day and allow the array to operate at > or = to half efficiency for another two hours per day. But the ability of the existing structure to support such a system and the durability and maintainability of such a structure over 20 years of wind and rain by myself is highly questionable, given my present age of 70. :-) But it would offer about a third more generation which would be highly significant for off grid type applications. Too bad the wind resource is not greater locally.
