The Trail is already filling up with garish homes and event centers and parking lots and left turn bumps and now the indignity of an industrial power plant.
It's churlish, and un-PC, to bad-mouth solar power. But we should recognize, as solar power provides more and more of our energy, that solar collectors are attractive only in their novelty and their benefit toward prolonging life on earth. In fact they are little different in appearance than a full parking lot.
As every home and business begins to burden the landscape with an array, the landscape will suffer. We see even now the jarring apparition of arrays climbing the hillsides behind homes and wineries, with little thought about their visual impact, but much admiration for the "green" commitment of their owners. And large solar arrays, as with the half acre at Rector, are significant money makers that will further speed their adoption, particularly in areas with a lot of open space - like Napa. It is really time for a solar array ordinance to "mitigate" (I would prefer "eliminate") their visual impacts and potential consumption of ag land going forward.
About the Rector array: this is an ideal opportunity to propose a 6-8' berm (a modest bit of earthwork perhaps garnished with vines) at the front of the property to hide both the panels and the corporation yard with its industrial detritus. It could be constructed perhaps with a bit of the 1400 acre feet of silt washed down from the vineyard development in the hills that currently diminishes the capacity of the reservoir. A definite win-win for all.
