Some of the barn quilts in other counties or states are actually painted directly on the barns. For the Sac County, Iowa project, the decision was made to paint the barn quilts on two 4' x 8' sheets of plywood, then eventually mount the plywood on the barn.
A solar panel is a panel exposed to radiation from the sun, that is used to heat water or, when mounted with solar cells, to produce electricity. 1  The solar panel charges a battery during the day that powers our proprietary light bulbs which automatically come on via a light sensor and timer system at night. The solar panel has high efficiency crystalline solar cells, and is easy to install and completely maintenance free.
A solar cell, or photovoltaic cell (in very early days also termed solar battery â a denotation which nowadays has a totally different meaning, see here), is an electrical device that converts the energy of light directly into electricity by the photovoltaic effect, which is a physical and chemical phenomenon.
