Note how the black-on-black Siliken panels give this 4,000-watt solar electric system a uniform look. New England Clean Energy leaves some inches between the roof and the panels to increase air flow, which cools the panels and increases energy production. This method also deters squirrels from building nests under the panels, and brush and ice from building up.
